I'm trying to make a simple GET request using cURL directly but I'm not able to get the response.
public function getSiteLicenses($page = 1) {
$url = 'https://testdomain.com';
$header = array('Key:somekey');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch,CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$response = curl_exec($ch);
curl_close($ch);
return json_decode($response, true);
}
The alternate way for me is to use some HTTP library, which works fine but I want to avoid using the library and use cURL directly.
public function getSiteLicenses($page = 1) {
$url = 'https://testdomain.com';
$siteLicenses = \Httpful\Request::get($url)
->addHeader("KEY", $this->apikey)
->send();
$siteLicensesArray = json_decode($siteLicenses, true);
return $siteLicensesArray;
}
What am I missing for requesting GET method using cURL directly? Thanks

I tried a few several ways to read the responses custom header but have not been able to. I know the response I get is served by nginx and the custom header names start with X-......
$endpoint = 'url here';
$ch = curl_init( $endpoint );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'cbFunc');
$result = curl_exec($ch);
print_r( curl_getinfo($ch ) );
The PHP manual is an excellent reference guide an a good starting point when you run into problems like this.
CURLOPT_HEADERFUNCTION [Set value to] A callback accepting five parameters.
hence
log_headers('init');
$endpoint = 'url here';
$ch = curl_init( $endpoint );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'log_headers');
$result = curl_exec($ch);
$headers=log_headers();
print_r($headers);
function log_headers($ch=false, $headers=false)
{
static $hdrs;
if (is_array($hrs) && $ch===$headers===false) {
return $hdrs[];
} elseif ($ch==='init') {
$hdrs=array();
return 0;
}
$hdrs[]=$headers;
return strlen($headers);
}
I have rest API of Nodejs Server, I'm trying to make a POST call to it using PHP.
My php code is:
function post_url($apiRoute,$data) {
$request_url = 'http://test-app.herokuapp.com';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $request_url . $apiRoute);
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
curl_setopt($ch, CURLOPT_POST, 1);
echo $data ;
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
//curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
I have tried calling this function with diff forms of data:
$g = array("_id" => "111");
$postapiresponse = post_url('/CCTRequest/get',json_encode($g));
OR
$postapiresponse = post_url('/CCTRequest/get',json_encode(array("_id" => "111"));
But on server side which Node.js, when I console log req.body I get data like this:
{ '{"_id":"111"}': '' }
How should I pass the data in PHP so I can get proper obj in node.js i.e:
{ '_id': '111' }
See the PHP document:
http://php.net/manual/en/function.curl-setopt.php
CURLOPT_POST:
TRUE to do a regular HTTP POST. This POST is the normal
application/x-www-form-urlencoded kind, most commonly used by HTML forms.
CURLOPT_POSTFIELDS:
If value is an array, the Content-Type header will be set to multipart/form-data.
So you can pass a query string returned by http_build_query() into CURLOPT_POSTFIELDS:
post_url('/CCTRequest/get', http_build_query($g, null, '&'));
and remove curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));. (In fact, the varieble should be $ch, but you typed $curl, so this line doesn't work.)
In the other way, you can replace curl_setopt($ch, CURLOPT_POST, 1); with
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');, it can prevent the data be encoded automaticlly. And then send json_encode() data.
I have solved by using http_build_query($g, null, '&') for making data.
$g = array("_id" => "111");
$g = http_build_query($g, null, '&');
$postapiresponse = post_url('/CCTRequest/get', $g);
You have a typo in the code, which will prevent it setting the header $curl should be $ch:
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
You also need CURLOPT_RETURNTRANSFER uncommented.
function post_url($apiRoute, $data) {
$request_url = 'www.example.com';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $request_url . $apiRoute);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type:application/json']);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
I have been working on building an Rest API for the hell of it and I have been testing it out as I go along by using curl from the command line which is very easy for CRUD
I can successfully make these call from the command line
curl -u username:pass -X GET http://api.mysite.com/pet/1
curl -d '{"dog":"tall"}' -u username:pass -X GET http://api.mysite.com/pet
curl -d '{"dog":"short"}' -u username:pass -X POST http://api.mysite.com/pet
curl -d '{"dog":"tall"}' -u username:pass -X PUT http://api.mysite.com/pet/1
The above calls are easy to make from the command line and work fine with my api, but now I want to use PHP to create the curl. As you can see, I pass data as a json string. I have read around and I think I can probably do the POST and include the POST fields, but I have not been able to find out how to pass http body data with GET. Everything I see says you must attached it to the url, but it doesn't look that way on the command line form. Any way, I would love it if someone could write the correct way to do these four operations in PHP here on one page. I would like to see the simplest way to do it with curl and php. I think I need to pass everything through the http body because my php api catching everything with php://input
PUT
$data = array('username'=>'dog','password'=>'tall');
$data_json = json_encode($data);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json','Content-Length: ' . strlen($data_json)));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
POST
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
GET
See #Dan H answer
DELETE
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
You can use this small library: https://github.com/ledfusion/php-rest-curl
Making a call is as simple as:
// GET
$result = RestCurl::get($URL, array('id' => 12345678));
// POST
$result = RestCurl::post($URL, array('name' => 'John'));
// PUT
$result = RestCurl::put($URL, array('$set' => array('lastName' => "Smith")));
// DELETE
$result = RestCurl::delete($URL);
And for the $result variable:
$result['status'] is the HTTP response code
$result['data'] an array with the JSON response parsed
$result['header'] a string with the response headers
Hope it helps
For myself, I just encode it in the url and use $_GET on the destination page. Here's a line as an example.
$ch = curl_init();
$this->json->p->method = "whatever";
curl_setopt($ch, CURLOPT_URL, "http://" . $_SERVER['SERVER_NAME'] . $this->json->path . '?json=' . urlencode(json_encode($this->json->p)));
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);
EDIT: Adding the destination snippet... (EDIT 2 added more above at OPs request)
<?php
if(!isset($_GET['json']))
die("FAILURE");
$json = json_decode($_GET['json']);
$method = $json->method;
...
?>
I was Working with Elastic SQL plugin.
Query is done with GET method using cURL as below:
curl -XGET http://localhost:9200/_sql/_explain -H 'Content-Type: application/json' \
-d 'SELECT city.keyword as city FROM routes group by city.keyword order by city'
I exposed a custom port at public server, doing a reverse proxy with Basic Auth set.
This code, works fine plus Basic Auth Header:
$host = 'http://myhost.com:9200';
$uri = "/_sql/_explain";
$auth = "john:doe";
$data = "SELECT city.keyword as city FROM routes group by city.keyword order by city";
function restCurl($host, $uri, $data = null, $auth = null, $method = 'DELETE'){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $host.$uri);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
if ($method == 'POST')
curl_setopt($ch, CURLOPT_POST, 1);
if ($auth)
curl_setopt($ch, CURLOPT_USERPWD, $auth);
if (strlen($data) > 0)
curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
$resp = curl_exec($ch);
if(!$resp){
$resp = (json_encode(array(array("error" => curl_error($ch), "code" => curl_errno($ch)))));
}
curl_close($ch);
return $resp;
}
$resp = restCurl($host, $uri); //DELETE
$resp = restCurl($host, $uri, $data, $auth, 'GET'); //GET
$resp = restCurl($host, $uri, $data, $auth, 'POST'); //POST
$resp = restCurl($host, $uri, $data, $auth, 'PUT'); //PUT
set one more property curl_setopt($ch, CURLOPT_SSL_VERIFYPEER , false);
I have the following bit of PHP, it works locally (via apache and localhost) but not on my hosting - $response is always empty:
function get_data($url) {
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$api_key = 'my_api_key';
$randomString = generateRandomString(10);
$endLabel = sha1(md5($randomString));
$user_id = $endLabel;
$amount_doge = '5';
$url = "https://dogeapi.com/wow/?api_key=".$api_key."&a=get_new_address&address_label=".$user_id;
$response = get_data($url);
I wondered if this could be because I'm hosted on HTTP (no SSL option) and I'm calling a HTTPS domain? If so, is there a way around this? I've tried curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); but it doesn't seem to do anything :(
try to use echo curl_error($ch) after $data = curl_exec($ch); to see what curl says
it wil lreport you what happened
I have a Affiliate URL Like http://track.abc.com/?affid=1234
open this link will go to http://www.abc.com
now i want to execute the http://track.abc.com/?affid=1234 Using CURL
and now how i can Get http://www.abc.com
with Curl ?
If you want cURL to follow redirect headers from the responses it receives, you need to set that option with:
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
You may also want to limit the number of redirects it follows using:
curl_setopt($ch, CURLOPT_MAXREDIRS, 3);
So you'd using something similar to this:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://track.abc.com/?affid=1234");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_MAXREDIRS, 3);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$data = curl_exec($ch);
Edit: Question wasn't exactly clear but from the comment below, if you want to get the redirect location, you need to get the headers from cURL and parse them for the Location header:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://track.abc.com/?affid=1234");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, true);
$data = curl_exec($ch);
This will give you the headers returned by the server in $data, simply parse through them to get the location header and you'll get your result. This question shows you how to do that.
I wrote a function that will extract any header from a cURL header response.
function getHeader($headerString, $key) {
preg_match('#\s\b' . $key . '\b:\s.*\s#', $headerString, $header);
return substr($header[0], strlen($key) + 3, -2);
}
In this case, you're looking for the value of the header Location. I tested the function by retrieving headers from a TinyURL, that redirects to http://google.se, using cURL.
$url = "http://tinyurl.com/dtrkv";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
curl_close($ch);
$location = getHeader($data, 'Location');
var_dump($location);
Output from the var_dump.
string(16) "http://google.se"
