PHP cURL GET请求和请求的正文

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

我正在尝试使用cURL来获取这样的GET请求:

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?

正如你所见,我想传递$ body作为请求的正文,但我不知道它是否正确,我实际上无法调试,你知道是否正确使用curl_setopt($ ch,CURLOPT_POSTFIELDS ,$机构);有GET请求?

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

因为这个enteire代码与POST完美配合,现在我正在尝试将此更改为GET,如您所见

4 个解决方案

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.

CURLOPT_POSTFIELDS顾名思义,是针对POST请求的正文(有效负载)。对于GET请求,有效负载是查询字符串形式的URL的一部分。

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.

在您的情况下,您需要使用您需要发送的参数(如果有)构造URL,并删除cURL的其他选项。

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);

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

接受的答案是错误的。 GET请求确实可以包含一个正文。这是WordPress实现的解决方案,例如:

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

EDIT: To clarify, the initial curl_setopt is not necessary in this instance, but does no harm. It was included to fully illustrate the example code being referenced.

编辑:为了澄清,在这种情况下,初始curl_setopt不是必需的,但没有坏处。包含它是为了充分说明被引用的示例代码。

  <?php
  $post = ['batch_id'=> "2"];
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL,'https://example.com/student_list.php');
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
  $response = curl_exec($ch);
  $result = json_decode($response);
  $new=   $result->status;
  if( $new =="1")
  {
    echo "<script>alert('Student list')</script>";
  }
  else 
  {
    echo "<script>alert('Not Removed')</script>";
  }

  ?>
