PHP cURL GET request and request's body

Question

i'm trying using cURL for a GET request like this:

function connect($id_user){     $ch = curl_init();     $headers = array(     'Accept: application/json',     'Content-Type: application/json',      );     curl_setopt($ch, CURLOPT_URL, $this->service_url.'user/'.$id_user);     curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);     curl_setopt($ch, CURLOPT_HEADER, 0);     $body = '{}';      curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");      curl_setopt($ch, CURLOPT_POSTFIELDS,$body);     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);      // Timeout in seconds     curl_setopt($ch, CURLOPT_TIMEOUT, 30);      $authToken = curl_exec($ch);      return $authToken; } 

As you an see i want to pass $body as the request's body , but i don't know if its correct or not and i can't debug this actually, do you know if is the right to use curl_setopt($ch, CURLOPT_POSTFIELDS,$body); with a GET request?

Cause this enteire code works perfect with POST, now i'm trying change this to GET as you can see

Answer 1

The accepted answer is wrong. GET requests can indeed contain a body. This is the solution implemented by WordPress, as an example:

curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, 'GET' ); curl_setopt( $ch, CURLOPT_POSTFIELDS, $body ); 

EDIT: To clarify, the initial curl_setopt is necessary in this instance, because libcurl will default the HTTP method to POST when using CURLOPT_POSTFIELDS (see documentation).

Answer 2

CURLOPT_POSTFIELDS as the name suggests, is for the body (payload) of a POST request. For GET requests, the payload is part of the URL in the form of a query string.

In your case, you need to construct the URL with the arguments you need to send (if any), and remove the other options to cURL.

curl_setopt($ch, CURLOPT_URL, $this->service_url.'user/'.$id_user); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_HEADER, 0);  //$body = '{}'; //curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");  //curl_setopt($ch, CURLOPT_POSTFIELDS,$body); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
