PHP cURL GET请求和请求的正文 [英] PHP cURL GET request and request's body

问题描述

我正在尝试使用cURL作为GET请求，如下所示：

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;
}

因为你看到我想传递$ body作为请求的身体，我不知道它的正确与否，我不能调试这个实际上，你知道是否是正确的使用 curl_setopt（$ ch，CURLOPT_POSTFIELDS，$ body）; 有GET请求？

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?

因为这个enteire代码与POST完美配合，现在我尝试改变这个GET，你可以看到

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

推荐答案

CURLOPT_POSTFIELDS 顾名思义，用于 POST 请求。对于 GET 请求，有效内容是以查询字符串形式的URL的一部分。

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.

，您需要使用您需要发送的参数（如果有）构建URL，并删除cURL的其他选项。

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);
