PHP cURL GET request and request's body -

I'm trying to use cURL for a GET request like this:

 < Code> function connected ($ Id_user) {$ ch = curl_init (); $ Header = array ('approve: app / jason', 'content-type: app / json'); Curl_setopt ($ ch, CURLOPT_URL, $ this- & gt; 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); // timed second curl_setopt ($ ch, CURLOPT_TIMEOUT, 30); $ AuthToken = curl_exec ($ ch); Return $ authToken; }   
 As you see, I want to pass $ body as the request body, but I do not know whether it is correct and I actually debug it Can not you know, if you have the right to use  curl_setopt ($ CH, CURLOPT_POSTFIELDS, $ body);  with a GET request?  
 Because this enteire code works perfectly with POST, now I am trying to change it to change it as you can see   
 < Div class = "post-text" itemprop = "text"> 
  CURLOPT_POSTFIELDS  as the name suggests, for a  post  request body (payload) For the  received  requests, the payload is part of the URL as a query string.  
 In your case, you need to create a URL that is required to send you (if any), and remove other options in the CRL.  
  curl_setopt ($ ch, CURLOPT_URL, $ this-> Services_urzell.username '. $ 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);
