Question

获取空消息作为响应PHP CURL

我尝试了print_r，http代码是200，即使CURLOPT_VERBOSE也没有显示错误。但是，它没有返回任何值。

curl = curl_init();
curl_setopt_array($curl, array(
  CURLOPT_URL => "http://dummy.com/xxx",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_VERBOSE=>true,
  CURLOPT_TIMEOUT => 50,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_CUSTOMREQUEST => "POST",
    CURLOPT_POSTFIELDS => $payload,
    CURLOPT_HTTPHEADER => array(
      "Authorization: Basic xxx",
    ),
  ));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "error:" . $err;
} else {
  echo "response: ".$response;
}

我得到

response: 
when I do CURLOPT_VERBOSE, this returned:
*   Trying xxx.xx.xx.xxx...
* TCP_NODELAY set
* Connected to xxx.xx.xx.xxx (xxx.xx.xx.xxx) port xxxx (#0)

有任何PHP大师需要帮助吗？

Answer 1

Content-Length: 0表示您内容的长度为零。

实际上，在POST请求中不返回任何内容是一个好习惯。因此，您的curl代码可能工作正常。

此响应的目的只是为您设置会话cookie。使用此Cookie，您可以发送其他已被授权的请求。

Answer 2

我找到了答案，有效载荷必须是json_encode（）-ed。这很糟糕
