Can anyone show me how to do a PHP cURL with an HTTP POST?
I want to send data like this:
username=user1, password=passuser1, gender=1
To www.example.com
I expect the cURL to return a response like result=OK. Are there any examples?
<?php
//
// A very simple PHP example that sends a HTTP POST to a remote site
//
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"http://www.example.com/tester.phtml");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
"postvar1=value1&postvar2=value2&postvar3=value3");
// In real life you should use something like:
// curl_setopt($ch, CURLOPT_POSTFIELDS,
// http_build_query(array('postvar1' => 'value1')));
// Receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec($ch);
curl_close($ch);
// Further processing ...
if ($server_output == "OK") { ... } else { ... }
?>
Procedural
// set post fields
$post = [
'username' => 'user1',
'password' => 'passuser1',
'gender' => 1,
];
$ch = curl_init('http://www.example.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
// execute!
$response = curl_exec($ch);
// close the connection, release resources used
curl_close($ch);
// do anything you want with your response
var_dump($response);
Object oriented
<?php
// mutatis mutandis
namespace MyApp\Http;
class CurlPost
{
private $url;
private $options;
/**
* #param string $url Request URL
* #param array $options cURL options
*/
public function __construct($url, array $options = [])
{
$this->url = $url;
$this->options = $options;
}
/**
* Get the response
* #return string
* #throws \RuntimeException On cURL error
*/
public function __invoke(array $post)
{
$ch = \curl_init($this->url);
foreach ($this->options as $key => $val) {
\curl_setopt($ch, $key, $val);
}
\curl_setopt($ch, \CURLOPT_RETURNTRANSFER, true);
\curl_setopt($ch, \CURLOPT_POSTFIELDS, $post);
$response = \curl_exec($ch);
$error = \curl_error($ch);
$errno = \curl_errno($ch);
if (\is_resource($ch)) {
\curl_close($ch);
}
if (0 !== $errno) {
throw new \RuntimeException($error, $errno);
}
return $response;
}
}
Usage
// create curl object
$curl = new \MyApp\Http\CurlPost('http://www.example.com');
try {
// execute the request
echo $curl([
'username' => 'user1',
'password' => 'passuser1',
'gender' => 1,
]);
} catch (\RuntimeException $ex) {
// catch errors
die(sprintf('Http error %s with code %d', $ex->getMessage(), $ex->getCode()));
}
Side note here: it would be best to create some kind of interface called AdapterInterface for example with getResponse() method and let the class above implement it. Then you can always swap this implementation with another adapter of your like, without any side effects to your application.
Using HTTPS / encrypting traffic
Usually there's a problem with cURL in PHP under the Windows operating system. While trying to connect to a https protected endpoint, you will get an error telling you that certificate verify failed.
What most people do here is to tell the cURL library to simply ignore certificate errors and continue (curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);). As this will make your code work, you introduce huge security hole and enable malicious users to perform various attacks on your app like Man In The Middle attack or such.
Never, ever do that. Instead, you simply need to modify your php.ini and tell PHP where your CA Certificate file is to let it verify certificates correctly:
; modify the absolute path to the cacert.pem file
curl.cainfo=c:\php\cacert.pem
The latest cacert.pem can be downloaded from the Internet or extracted from your favorite browser. When changing any php.ini related settings remember to restart your webserver.
A live example of using php curl_exec to do an HTTP post:
Put this in a file called foobar.php:
<?php
$ch = curl_init();
$skipper = "luxury assault recreational vehicle";
$fields = array( 'penguins'=>$skipper, 'bestpony'=>'rainbowdash');
$postvars = '';
foreach($fields as $key=>$value) {
$postvars .= $key . "=" . $value . "&";
}
$url = "http://www.google.com";
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST, 1); //0 for a get request
curl_setopt($ch,CURLOPT_POSTFIELDS,$postvars);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT ,3);
curl_setopt($ch,CURLOPT_TIMEOUT, 20);
$response = curl_exec($ch);
print "curl response is:" . $response;
curl_close ($ch);
?>
Then run it with the command php foobar.php, it dumps this kind of output to screen:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Title</title>
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Expires" content="0">
<body>
A mountain of content...
</body>
</html>
So you did a PHP POST to www.google.com and sent it some data.
Had the server been programmed to read in the post variables, it could decide to do something different based upon that.
It's can be easily reached with:
<?php
$post = [
'username' => 'user1',
'password' => 'passuser1',
'gender' => 1,
];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.domain.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
$response = curl_exec($ch);
var_export($response);
1.Step by step
Initialize the cURL session:
$url = "www.domain.com";
$ch = curl_init($url);
If your request has headers like bearer token or defining JSON contents you have to set HTTPHEADER options to cURL:
$token = "generated token code";
curl_setopt(
$ch,
CURLOPT_HTTPHEADER,
array(
'Content-Type: application/json', // for define content type that is json
'bearer: '.$token, // send token in header request
'Content-length: 100' // content length for example 100 characters (can add by strlen($fields))
)
);
If you want to include the header in the output set CURLOPT_HEADER to true:
curl_setopt($ch, CURLOPT_HEADER, false);
Set RETURNTRANSFER option to true to return the transfer as a string instead of outputting it directly:
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
To check the existence of a common name in the SSL peer certificate can be set to 0(to not check the names), 1(not supported in cURL 7.28.1), 2(default value and for production mode):
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
For posting fields as an array by cURL:
$fields = array(
"username" => "user1",
"password" => "passuser1",
"gender" => 1
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
Execute cURL and return the string. depending on your resource this returns output like result=OK:
$result = curl_exec($ch);
Close cURL resource, and free up system resources:
curl_close($ch);
2.Use as a class
The whole call_cURL class that can be extended:
class class_name_for_call_cURL {
protected function getUrl() {
return "www.domain.com";
}
public function call_cURL() {
$token = "generated token code";
$fields = array(
"username" => "user1",
"password" => "passuser1",
"gender" => 1
);
$url = $this->getUrl();
$output = $this->_execute($fields, $url, $token);
// if you want to get json data
// $output = json_decode($output);
if ($output == "OK") {
return true;
} else {
return false;
}
}
private function _execute($postData, $url, $token) {
// for sending data as json type
$fields = json_encode($postData);
$ch = curl_init($url);
curl_setopt(
$ch,
CURLOPT_HTTPHEADER,
array(
'Content-Type: application/json', // if the content type is json
'bearer: '.$token // if you need token in header
)
);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
}
Using the class and call cURL:
$class = new class_name_for_call_cURL();
var_dump($class->call_cURL()); // output is true/false
3.One function
A function for using anywhere that needed:
function get_cURL() {
$url = "www.domain.com";
$token = "generated token code";
$postData = array(
"username" => "user1",
"password" => "passuser1",
"gender" => 1
);
// for sending data as json type
$fields = json_encode($postData);
$ch = curl_init($url);
curl_setopt(
$ch,
CURLOPT_HTTPHEADER,
array(
'Content-Type: application/json', // if the content type is json
'bearer: '.$token // if you need token in header
)
);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
This function is usable just by:
var_dump(get_cURL());
Curl Post + Error Handling + Set Headers [thanks to #mantas-d]:
function curlPost($url, $data=NULL, $headers = NULL) {
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
if(!empty($data)){
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
}
if (!empty($headers)) {
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
}
$response = curl_exec($ch);
if (curl_error($ch)) {
trigger_error('Curl Error:' . curl_error($ch));
}
curl_close($ch);
return $response;
}
curlPost('google.com', [
'username' => 'admin',
'password' => '12345',
]);
curlPost('google.com', [
'username' => 'admin',
'password' => '12345',
]);
function curlPost($url, $data) {
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$response = curl_exec($ch);
$error = curl_error($ch);
curl_close($ch);
if ($error !== '') {
throw new \Exception($error);
}
return $response;
}
I'm surprised nobody suggested file_get_contents:
$url = "http://www.example.com";
$parameters = array('username' => 'user1', 'password' => 'passuser1', 'gender' => '1');
$options = array('http' => array(
'header' => 'Content-Type: application/x-www-form-urlencoded\r\n',
'method' => 'POST',
'content' => http_build_query($parameters)
));
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
it's simple, it works; I use it in an environment where I control the code at both ends.
even better, use json_decode (and set up your code to return JSON)
$result = json_decode(file_get_contents($url, false, $context), TRUE);
this approach invokes curl behind the scenes, but you don't jump through as many hoops.
Answer refined from this original answer elsewhere on Stack Overflow:
PHP sending variables to file_get_contents()
If the form is using redirects, authentication, cookies, SSL (https), or anything else other than a totally open script expecting POST variables, you are going to start gnashing your teeth really quick. Take a look at Snoopy, which does exactly what you have in mind while removing the need to set up a lot of the overhead.
A simpler answer IF you are passing information to your own website is to use a SESSION variable. Begin php page with:
session_start();
If at some point there is information you want to generate in PHP and pass to the next page in the session, instead of using a POST variable, assign it to a SESSION variable. Example:
$_SESSION['message']='www.'.$_GET['school'].'.edu was not found. Please try again.'
Then on the next page you simply reference this SESSION variable. NOTE: after you use it, be sure you destroy it, so it doesn't persist after it is used:
if (isset($_SESSION['message'])) {echo $_SESSION['message']; unset($_SESSION['message']);}
Here are some boilerplate code for PHP + curl
http://www.webbotsspidersscreenscrapers.com/DSP_download.php
include in these library will simplify development
<?php
# Initialization
include("LIB_http.php");
include("LIB_parse.php");
$product_array=array();
$product_count=0;
# Download the target (store) web page
$target = "http://www.tellmewhenitchanges.com/buyair";
$web_page = http_get($target, "");
...
?>
Examples of sending form and raw data:
$curlHandler = curl_init();
curl_setopt_array($curlHandler, [
CURLOPT_URL => 'https://postman-echo.com/post',
CURLOPT_RETURNTRANSFER => true,
/**
* Specify POST method
*/
CURLOPT_POST => true,
/**
* Specify array of form fields
*/
CURLOPT_POSTFIELDS => [
'foo' => 'bar',
'baz' => 'biz',
],
]);
$response = curl_exec($curlHandler);
curl_close($curlHandler);
echo($response);
If you try to login on site with cookies.
This code:
if ($server_output == "OK") { ... } else { ... }
It May not works if you try to login, because many sites return status 200, but the post is not successful.
The easy way to check if the login post is successful is to check if it setting cookies again. If in output have a Set-Cookies string, this means the posts are not successful and it starts a new session.
Also, the post can be successful, but the status can redirect instead of 200.
To be sure the post is successful try this:
Follow location after the post, so it will go to the page where the post does redirect to:
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
And than check if new cookies existing in the request:
if (!preg_match('/^Set-Cookie:\s*([^;]*)/mi', $server_output))
{echo 'post successful'; }
else { echo 'not successful'; }
Easiest is to send data as application/json. This will take an array as input and properly encodes it into a json string:
$data = array(
'field1' => 'field1value',
'field2' => 'field2value',
)
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type:application/json',
));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$resultStr = curl_exec($ch);
return json_decode($resultStr, true);
Just wondering if anyone knew what I was doing wrong here?
I am trying to get data from an API for bitcoin via php. However, I am getting no results from my php page.
$url = "https://api.coinmarketcap.com/v1/ticker/bitcoin/?convert=EUR";
$json = file_get_contents($url);
$json_data = json_decode($json, true);
echo "ID: ". $json_data["id"];
However I am getting nothing show at all on the php page. If I use the code below, It works and dumps out the entire information. But, I would prefer to obtain the information separately, instead of one big dump.
$url = "https://api.coinmarketcap.com/v1/ticker/bitcoin/?convert=EUR";
$ch = curl_init();
// Disable SSL verification
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL,$url);
// Execute
$result=curl_exec($ch);
// Closing
curl_close($ch);
var_dump(json_decode($result, true));
Anyone have any ideas why the first code block isn't working? Thanks! Very new to API and Json
Using cURL is much better
Updated code (needs error checking)
$url = "https://api.coinmarketcap.com/v1/ticker/bitcoin/?convert=EUR";
$ch = curl_init();
// Disable SSL verification
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL,$url);
// Execute
$result=curl_exec($ch);
// Closing
curl_close($ch);
$json_data = json_decode($result, true);
foreach ($json_data as $item)
echo "ID: ". $item["id"];
I have printed the result it will produce following output
echo "<pre>";
print_r(json_decode($result, true));
Array
(
[0] => Array
(
[id] => bitcoin
[name] => Bitcoin
[symbol] => BTC
[rank] => 1
[price_usd] => 3821.37
[price_btc] => 1.0
[24h_volume_usd] => 2089880000.0
[market_cap_usd] => 63298556016.0
[available_supply] => 16564362.0
[total_supply] => 16564362.0
[percent_change_1h] => -1.72
[percent_change_24h] => -4.57
[percent_change_7d] => -15.76
[last_updated] => 1505359771
[price_eur] => 3214.536444
[24h_volume_eur] => 1758007056.0
[market_cap_eur] => 53246745321.0
)
)
so you can use foreach loop if your api contain multiple
$data=json_decode($result, true);
foreach($data as $key=>$val){
echo $val->id;
}
full code
<?php
$url = "https://api.coinmarketcap.com/v1/ticker/bitcoin/?convert=EUR";
$ch = curl_init();
// Disable SSL verification
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL,$url);
// Execute
$result=curl_exec($ch);
// Closing
curl_close($ch);
$data=json_decode($result, true));
foreach($data as $key=>$val){
echo $val->id;
}
The setting you are looking for is allow_url_fopen.
You have two ways of getting around it without changing php.ini, one of them is to use fsockopen(), and the other is to use cURL.
I recommend using cURL over file_get_contents() anyways, since it was built for this.
I have tried calling the API using standard URL. All work perfectly directly from the browser. For e.g.:
http://www.worldcat.org/webservices/catalog/search/sru?query=srw.su%3D%22Computer organization%22&startRecord=101&maximumRecords=100&wskey=7Rn7E7osoeJeQURAiEO4GH74HZa6BLdt7eXahgxdvwnfO6Ph7za1OzU9M2zx0e9nuDHVO34b5HfnLuOw
http://www.worldcat.org/webservices/catalog/search/sru?query=srw.su%3D%22Computer engineering%22&startRecord=101&maximumRecords=100&wskey=7Rn7E7osoeJeQURAiEO4GH74HZa6BLdt7eXahgxdvwnfO6Ph7za1OzU9M2zx0e9nuDHVO34b5HfnLuOw
But when I use cURL to do it, I keep on having the error from the API that the wskey is not attached:
function curl_get_contents($url)
{
$ch = curl_init();
d($url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
d($OCLCqueries);
foreach ($OCLCqueries as $OCLCquery) {
// echo "managed1";
$XMLdata = curl_get_contents($OCLCquery);
// echo "managed2";
}
I defined $OCLCqueries earlier. It is an array that contains the URL calls as values.
d() is a function that I call from an installed library which is a more sophisticated form of var_dump(), basically having the same purpose (serve as breakpoints for debugging) but dumping the data in a more human-readable format.
This is the output I have:
<body><h1>HTTP Status 400 - org.oclc.wskey.api.WSKeyException: WsKeyParam(wskey) not found in request</h1><HR size="1" noshade="noshade"><p><b>type</b> Status report</p><p><b>message</b> <u>org.oclc.wskey.api.WSKeyException: WsKeyParam(wskey) not found in request</u></p><p><b>description</b> <u>The request sent by the client was syntactically incorrect (org.oclc.wskey.api.WSKeyException: WsKeyParam(wskey) not found in request).</u></p><HR size="1" noshade="noshade"><h3></h3></body>
How do I solve this problem?
Initially I thought the most likely reason for the failure was a lack of User-Agent string in the request but found, when testing the code below, that it's existence or not made no difference so I believe the problem is the format of the url used in the cURL request as it is already encoded. By separating the baseurl and the parameters as below it works fine.
$url='http://www.worldcat.org/webservices/catalog/search/sru';
$params=array(
'query' => 'srw.su="Computer organization"',
'startRecord' => 101,
'maximumRecords' => 100,
'wskey' => '7Rn7E7osoeJeQURAiEO4GH74HZa6BLdt7eXahgxdvwnfO6Ph7za1OzU9M2zx0e9nuDHVO34b5HfnLuOw'
);
function curl_get_contents( $url=false, $params=array() ){
if( $url && !empty( $params ) ){
$url = $url . '?' . http_build_query( $params );
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0 );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($ch, CURLOPT_URL, $url );
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:44.0) Gecko/20100101 Firefox/44.0' );
$data = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
return (object)array(
'response' => $data,
'info' => $info
);
}
}
$data = curl_get_contents( $url, $params );
print_r( $data->response );
To simplify the call to the main function you could create a simple wrapper function like this.
function getcatalog( $baseurl=false, $term=false, $start=1, $max=1, $key=false ){
if( $baseurl && $term && $key ){
$params=array(
'query' => 'srw.su="'.$term.'"',
'startRecord' => $start,
'maximumRecords' => $max,
'wskey' => $key
);
return curl_get_contents( $baseurl, $params );
}
}
$data = getcatalog( $url, 'Computer organization', 1, 100,'7Rn7E7osoeJeQURAiEO4GH74HZa6BLdt7eXahgxdvwnfO6Ph7za1OzU9M2zx0e9nuDHVO34b5HfnLuOw');
if( $data->info['http_code']==200 ){
print_r( $data->response );
}
I have script that calls at script via cURL. It looks like this,
Route::get('login-redirect', function() {
if (Input::has('error')) {
return Input::get('error_description');
}
if (Input::has('code')) {
$fields = array(
'grant_type' => 'password',
'username' => 'admin#local.com',
'password' => 'passwohrd',
'client_id' => 'testclient'
);
$fieldstring = http_build_query($fields, "\n");
$url = "http://apitest.local/api/v1/get-token";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_POSTFIELDS, $fieldstring);
$result = curl_exec($ch);
$json = json_decode($result);
curl_close($ch);
$fields = array('access_token' => '3c1e6b099f172fc01304403939edf8e56904ab61');
$fieldstring = http_build_query($fields, "\n");
$url = "http://apitest.local/api/v1/me";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_POSTFIELDS, $fieldstring);
$result = curl_exec($ch);
curl_close($ch);
dd($result);
}
The json returned looks like this, if I do dd($json)
{"content":null,"error":true,"error_description":"Invalid username and password combination"}int(1)
I feel like after running it through json_decode I should be able to just output $json->error but no.
The JSON gets made in the following class, but I cannot see anything odd here either, I am doing incorrect, or do I misunderstand json_decode?
<?php
namespace Shaunpersad\ApiFoundation\Http;
use App;
use Response;
class ErrorResponse
{
public static function make($message = '', $status = 200, array $headers = array(), $options = 0)
{
$response = App::make(
'api_response_array',
array(
'content' => null,
'error' => true,
'error_description' => $message
)
);
return Response::json($response, $status, $headers, $options);
}
}
First of all, you do not have CURLOPT_RETURNTRANSFER - your curl_exec returns output buffer directly to the screen.
Second of all, it looks like you have var_dump somewhere and I cannot see where :)
Third of all - you didn't asked any direct question.
Edit
Okay i've read it few time and answer below. The dd() function is truly a var_dump wrapper but it is dumping var_dump data into json format afaics.
What you've got as an output is not from dd($json):
// this part has been output by curl_exec():
{"content":null,"error":true,"error_description":"Invalid username and password combination"}
// only this part comes from dd($json):
int(1)
Here's why:
// no CURLOPT_RETURNTRANSFER, so curl_exec() outputs result and returns true:
$result = curl_exec($ch);
// thus $result = true;
// so here $json = 1, since this is what json_decode(true) will return
$json = json_decode($result);
// then you did dd($json), so it just appended var_dump(1) to the output:
{"content":null,"error":true,"error_description":"Invalid username and password combination"}int(1)
Update
As stated in the other answers, you're not actually receiving the output because you haven't set CURLOPT_RETURNTRANSFER. So curl_exec() will echo out the response to the DOM and return true (1) as your curl request ran successfully.
You'll be able to run the below stuff by setting this in your curl request somewhere:
curl_setop(CURLOPT_RETURNTRANSFER, true);
dd() is a laravel function and this is what the documentation says:
Dump the given variable and end execution of the script.
I'd presume it is just a wrapper function for a prettier looking var_dump() (As I don't use laravel, I wouldn't know its exact output.).
What you want is to decode the $result that is returned from your cUrl. Something like this should suffice:
$data = json_decode($result);
echo $data->error_description;
The successfully decoded object looks like this:
stdClass Object
(
[content] =>
[error] => 1
[error_description] => Invalid username and password combination
)
Example
You can even test your boolean error value like this now:
if($data->error) {
//....true
} else {
//....false
}
I am sending payment info to Virtual merchant payment gateway for payment system using curl. This is my code :
$Url= "https://www.myvirtualmerchant.com/VirtualMerchant/process.do";
// is cURL installed yet?
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
// OK cool - then let's create a new cURL resource handle
$ch = curl_init();
// Now set some options (most are optional)
// Set URL to download
curl_setopt($ch, CURLOPT_URL, $Url);
// Include header in result? (0 = yes, 1 = no)
// curl_setopt($ch, CURLOPT_HEADER, 0);
// Should cURL return or print out the data? (true = return, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
$fields = array(
'ssl_card_number'=>urlencode($_POST['ssl_card_number']),
'ssl_exp_date'=>urlencode($_POST['ssl_exp_date']),
'ssl_cvv2cvc2'=>urlencode($_POST['ssl_cvv2cvc2']),
'ssl_avs_address'=>urlencode($_POST['ssl_avs_address']),
'ssl_avs_zip'=>urlencode($_POST['ssl_avs_zip']),
'ssl_merchant_id'=>urlencode($_POST['ssl_merchant_id']),
'ssl_user_id'=>urlencode($_POST['ssl_user_id']),
'ssl_pin'=>urlencode($_POST['ssl_pin']),
'ssl_transaction_type'=>urlencode($_POST['ssl_transaction_type']),
'ssl_amount'=>urlencode($_POST['ssl_amount']),
'ssl_show_form'=>urlencode($_POST['ssl_show_form']),
'TransactionType'=>urlencode($_POST['TransactionType'])
);
//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string,'&');
curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);
// Download the given URL, and return output
echo $output = curl_exec($ch);
// Close the cURL resource, and free system resources
curl_close($ch);
print_r($output);
But in $output i am getting nothing, not any error or message. Am i doing it wrong ? please tell me ?
First I'd check your mechant_id, pin, etc. Below is working code I created after working through a similar problem.
<html>
<body>
<p>--start--</p>
<?php
//if you have a live account don't use the "demo" post url it won't work
$post_url = 'https://www.myvirtualmerchant.com/VirtualMerchant/process.do';
//replace the xxx's with your proper merchant_id, etc.
//they will give you these when you activate your account
//I've set form to not show, and ssl_result_format =>ascii to get a string returned
$fields = array(
'ssl_merchant_id' =>'xxxxxx',
'ssl_user_id' =>'xxx',
'ssl_pin' =>'xxxxx',
'ssl_show_form' =>'false',
'ssl_result_format' =>'ascii',
'ssl_test_mode' =>'false',
'ssl_transaction_type' =>'ccsale',
'ssl_amount' =>'1.44',
'ssl_card_number' =>'5000300020003003',
'ssl_exp_date' =>'1214',
'ssl_avs_address' =>'Test 3',
'ssl_avs_zip' =>'123456',
'ssl_cvv2cvc2' =>'123',
);
//build the post string
$fields_string = '';
foreach($fields as $key=>$value) { $fields_string .=$key.'='.$value.'&'; }
rtrim($fields_string, "&");
//open curl session
// documentation on curl options at http://www.php.net/curl_setopt
$ch = curl_init();
//begin seting curl options
//set URL
curl_setopt($ch, CURLOPT_URL, $post_url);
//set method
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//set post data string
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
//these two options are frequently necessary to avoid SSL errors with PHP
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
$result = curl_exec($ch);
if($result === FALSE) {
//post failed
die(curl_error($ch));
} else {
//got a response
//some people seem to get name/value pairs delimited with "&"
//but currently mine is \n
//support told me there's no way to change it..
$response_array = explode("\n",$result);
//make it nice and useful
foreach( $response_array as $k=>$v ){
$v=explode("=",$v);
$a[$v[0]]=$v[1];
}
//show the whole array
print_r($a);
//use a specific return value
//returns "APPROVAL" if it went through
echo('<h1>'. $a[ssl_result_message] . '</h1>');
}
?>
<p>--end--</p>

The code above should net you a screen like this:
--start--
Array ( [ssl_card_number] => 50**********3003 [ssl_exp_date] => 1214 [ssl_amount] => 1.44 [ssl_customer_code] => [ssl_salestax] => [ssl_invoice_number] => [ssl_description] => [ssl_departure_date] => [ssl_completion_date] => [ssl_company] => [ssl_first_name] => [ssl_last_name] => [ssl_avs_address] => Test 3 [ssl_address2] => [ssl_city] => [ssl_state] => [ssl_avs_zip] => 123456 [ssl_country] => [ssl_phone] => [ssl_email] => [ssl_result] => 0 [ssl_result_message] => APPROVAL [ssl_txn_id] => AA49315-1234567-F78F-468F-AF1A-F5C4ADCFFB1E [ssl_approval_code] => N53032 [ssl_cvv2_response] => [ssl_avs_response] => [ssl_account_balance] => 0.00 [ssl_txn_time] => 01/15/2014 11:53:15 AM )
APPROVAL
--end--
Make sure you delete all these test purchases when you finished testing. I'm told they will inhibit your real purchases from posting.
try this to find out the error
var_dump(curl_error($ch));
before and calling curl_exec($ch);
You are calling an HTTPS page. Please refer to following link
http://unitstep.net/blog/2009/05/05/using-curl-in-php-to-access-https-ssltls-protected-sites/
Try to find error give this code before curl close:--
echo "Curl Error :--" . curl_error($ch);
if no error found do like this:-
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
then
print_r($result);
exit;
Try this:
$output = curl_exec($ch);
$response = curl_getinfo($ch);
echo "<pre>";
print_r($response);
echo "</pre>";
Hope you get the response :)
