JSON Encode To PHP Variable via Curl fails with empty response - php

i have searched a lot on google and here but im not getting any further with my problem. I am not a coder though I am trying to parse JSON to PHP Variables, but i get an empty response, where i want a table to be shown or at least any jsondata
Here is what my code looks like:
<!DOCTYPE html>
<html>
<body>
<h1>Available Agents </h1>
<?php
$url = 'https://url/livewebservice/imoscontactagentstate?Username=username&Pwd=password&Cmd=GetState&ResultType=JSON';
// Initiate curl
$ch = curl_init ($url);
$data = json_encode ($data,true);
curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt ($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($ch, CURLOPT_HTTPHEADER, array (
' Content-Type: application/x-www-form-urlencoded ',
'charset=utf-8')
);
$result = curl_exec ($ch);
curl_close ($ch);
return $result;
var_dump(json_decode($result, true));
print_r($result);
foreach ($result as $key => $value)
{
echo ' <td><font face="calibri"color="red">'.$value[type].' </font></td><td><font face="calibri"color="blue">'.$value[category].' </font></td><td><font face="calibri"color="green">'.$value[amount].' </font></tr><tr>';
}
echo "</tr></table>";
?>
</body>
</html>
I am grateful for any hints

Try to remove true from $data = json_encode ($data,true); as far as can i remember true is used only in json_decode to create an associative array

The problem was solved my Username did not have the permission to access the data and we made minor changes to the code so it looks like this:
php
$data = array(
"UserName" => "Username",
"Pwd" => "Password",
"Cmd" => "GetAgentStateList",
"ResultType" => "JSON",
);
$url='https://host/livewebservice/service/?'.http_build_query($data);
echo $url;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"Content-Type: application/x-www-form-urlencoded", "charset=UTF-8",));
$result = curl_exec($ch);
if(curl_errno($ch)){
throw new Exception(curl_error($ch));
}
curl_close($ch);
$f_result=json_decode($result);
print_r($f_result);
?>
i hope this helps someone coming from google someday.

Parsing object in PHP not working

I'm using this to get my response (only relevant code below):
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER,$headr);
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$result=curl_exec ($ch);
curl_close ($ch);
echo $result;
$my_resp = $result['total_count'];
var_dump($my_resp);
echo $result gives me an object that appears to be valid JSON. Like this:
{
"total_count": 1
}
However, $my_resp comes back as NULL. What am I doing wrong here?
You need to turn it into an object from a string
$result = json_decode( curl_exec($ch));
or an associative array
$result = json_decode( curl_exec($ch), true );
If it is JSON, you should json_decode() it before trying to read fields.

$_POST via cURL not working

Im trying my hand at using curl to post some data, I am not reciving my post content and can not find the source of the problem
curl.php
<?php
$data = array("user_email" => "22" , "pass" => "22" );
$string = http_build_query($data);
$ch = curl_init("http://localhost:8888/290_project/test.php"); //this is where post data goes too, also starts curl
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
curl_close($ch) //ends curl
?>
test.php
<?php
if(isset($_POST['user_email'], $_POST['pass'])) {
$name = $_POST['user_email'];
$pass = $_POST['pass'];
echo $name;
echo $pass;
} else {
echo "error";
} ?>
Every time I get my error response meaning the post data is not going through. I have tried everything I could think of to trouble shoot;I must be over looking something I am simply not yet familiar with?
Please set CURLOPT_URL to http://localhost:8888.....
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://localhost:8888/290_project/test.php");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
if(!curl_errno($ch)){
$info = curl_getinfo($ch);
} else {
echo 'Curl error: ' . curl_error($ch);
}
curl_close($ch) //ends curl
?>
With curl_getinfo() - Gets information about the last transfer.
For more detail read below link:- http://php.net/manual/en/function.curl-getinfo.php
I have edited the answer, The reason for error is not curl.
http_build_query($data, '', '&');
Following is working example. Please try this.
$postData = array(
'user_name' => 'abcd',
'password' => 'asdfghj',
'redirect' => 'yes',
'user_login' => '1'
);
$url='http://localhost:8888/290_project/test.php';
$ch = curl_init();
//Set the URL to work with
curl_setopt($ch, CURLOPT_URL, $url);
// ENABLE HTTP POST
curl_setopt($ch, CURLOPT_POST, 1);
//Set the post parameters
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//execute the request
$store = curl_exec($ch);
print_r($store);
curl_close($ch)
You have an error in your php code:
edit:
if(isset($_POST['user_email'], $_POST['pass'])) {
to:
if(isset($_POST['user_email']) && isset($_POST['pass'])) {

Post data with curl to another server

I try to post some data to another server using curl. The problem is that I get nothing on the other server.
Server1:
$a = $USER->id;
$b = $USER->username;
error_reporting(-1);
$url = 'http://remote_server/a.php';
$data = array(
'cus' => $a,
'cust' => $b
);
$postString = http_build_query($data, '', '&');
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_POST, 2);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postString);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$post = curl_exec ($ch);
curl_close ($ch);
and on Server2:
<?php
session_start();
var_dump($_POST);
?>
Of course it doesn't work, it gives array(0) {}.
So, how I will see the data on the other server?
To see the actual output of var_dump($_POST) in Server2, you must either :
Server1 side : echo $post variable
Server2 side : write the content of var_dump's result in a file :
ob_start();
var_dump($_POST);
$output = ob_get_clean();
$fp = fopen('log.txt', 'a');
fwrite($fp, $output);
fclose($fp);

Posting JSON data to API using CURL

When I'm posting json data to API using curl - I'm not getting any output. I would like to send email invitation to recipient.
$url_send ="http://api.address.com/SendInvitation?";
$str_data = json_encode($data);
function sendPostData ($url, $post) {
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
return curl_exec($ch);
}
And here is JSON $str_data
[
{
"authorizedKey" : "abbad35c5c01-xxxx-xxx",
"senderEmail" : "myemail#yahoo.com",
"recipientEmail" : "jaketalledo86#yahoo.com",
"comment" : "Invitation",
"forceDebitCard" : "false"
}
]
And calling function:
$response = sendPostData($url_send, $str_data);
This is the API: https://api.payquicker.com/Help/Api/POST-api-SendInvitation
Try adding curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
And changing http_build_query($post) to $post
The implementation:
<?php
$data = array(
"authorizedKey" => "abbad35c5c01-xxxx-xxx",
"senderEmail" => "myemail#yahoo.com",
"recipientEmail" => "jaketalledo86#yahoo.com",
"comment" => "Invitation",
"forceDebitCard" => "false"
);
$url_send ="http://api.payquicker.com/api/SendInvitation?authorizedKey=xxxxx";
$str_data = json_encode($data);
function sendPostData($url, $post){
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS,$post);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$result = curl_exec($ch);
curl_close($ch); // Seems like good practice
return $result;
}
echo " " . sendPostData($url_send, $str_data);
?>
The response I get is:
{"success":false,"errorMessage":"Object reference not set to an instance of an object.","status":"N/A"}
But maybe it will work with valid data....
Edit:
For posting xml,
it's the same as on their site, except in a string:
$xml = '
<SendInvitationRequest xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/PQApi.Models">
<authorizedKey>80c587b9-caa9-4e56-8750-a34b17dba0a2</authorizedKey>
<comment>sample string 4</comment>
<forceDebitCard>true</forceDebitCard>
<recipientEmail>sample string 3</recipientEmail>
<senderEmail>sample string 2</senderEmail>
</SendInvitationRequest>';
Then:
sendPostData($url_send, $xml)
You have to add header:
$headers= array('Accept: application/json','Content-Type: application/json');
And:
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
Otherwise ...
HTTP Status 415 - Unsupported Media Type
... may happen.
You don't need to add headers as you already do json_encode.
just print_r (curl_getinfo($ch)); and see the content type info in it.

php - using curl to consume this web service

I saw this post on consuming a web service using CURL: Consume WebService with php
and I was trying to follow it, but haven't had luck. I uploaded a photo of the web service I'm trying to access. How would I formulate my request given the example below, assuming the URL was:
https://site.com/Spark/SparkService.asmx?op=InsertConsumer
I attempted this, but it just returns a blank page:
$url = 'https://xxx.com/Spark/SparkService.asmx?op=InsertConsumer?NameFirst=Joe&NameLast=Schmoe&PostalCode=55555&EmailAddress=joe#schmoe.com&SurveyQuestionId=76&SurveyQuestionResponseId=1139';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
$xmlobj = simplexml_load_string($result);
print_r($xmlobj);
Really, you should probably look at the SOAP extension. If it is not available or for some reason you must use cURL, here is a basic framework:
<?php
// The URL to POST to
$url = "http://www.mysoapservice.com/";
// The value for the SOAPAction: header
$action = "My.Soap.Action";
// Get the SOAP data into a string, I am using HEREDOC syntax
// but how you do this is irrelevant, the point is just get the
// body of the request into a string
$mySOAP = <<<EOD
<?xml version="1.0" encoding="utf-8" ?>
<soap:Envelope>
<!-- SOAP goes here, irrelevant so wont bother writing it out -->
</soap:Envelope>
EOD;
// The HTTP headers for the request (based on image above)
$headers = array(
'Content-Type: text/xml; charset=utf-8',
'Content-Length: '.strlen($mySOAP),
'SOAPAction: '.$action
);
// Build the cURL session
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, $mySOAP);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
// Send the request and check the response
if (($result = curl_exec($ch)) === FALSE) {
die('cURL error: '.curl_error($ch)."<br />\n");
} else {
echo "Success!<br />\n";
}
curl_close($ch);
// Handle the response from a successful request
$xmlobj = simplexml_load_string($result);
var_dump($xmlobj);
?>
The service requires you to do a POST, and you're doing a GET (curl's default for HTTP urls) instead. Add this:
curl_setopt($ch, CURLOPT_POST);
and add some error handling:
$result = curl_exec($ch);
if ($result === false) {
die(curl_error($ch));
}
This is the best answer because using this once you need to login then
get some data from webservices(third party site data).
$tmp_fname = tempnam("/tmp", "COOKIE"); //create temporary cookie file
$post = array(
'username=abc#gmail.com',
'password=123456'
);
$post = implode('&', $post);
//login with username and password
$curl_handle = curl_init ("http://www.example.com/login");
//create cookie session
curl_setopt ($curl_handle, CURLOPT_COOKIEJAR, $tmp_fname);
curl_setopt ($curl_handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_handle, CURLOPT_POSTFIELDS, $post);
$output = curl_exec ($curl_handle);
//Get events data after login
$curl_handle = curl_init ("http://www.example.com/events");
curl_setopt ($curl_handle, CURLOPT_COOKIEFILE, $tmp_fname);
curl_setopt ($curl_handle, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec ($curl_handle);
//Convert json format to array
$data = json_decode($output);
echo "Output : <br> <pre>";
print_r($data);
echo "</pre>";
