在 curl 中使用 post 请求

Question

我在 php 中为发布请求写了几行代码。 在 Firefox 上尝试该请求有效，但不适用于 curl。

  public function action($key, $file){
       $this->ch = curl_init();
       $headers[] = "Accept-Encoding: gzip";
       $headers[] = "Connection: Keep-Alive";
       $headers[] = "Content-Type: application/x-www-form-urlencoded";

       $datas = "arg=test&action=upload";
       curl_setopt($this->ch, CURLOPT_URL, "http://test.com");
       curl_setopt($this->ch, CURLOPT_USERAGENT, $this->agent);
       curl_setopt($this->ch, CURLOPT_RETURNTRANSFER, 1);
       curl_setopt($this->ch, CURLOPT_FOLLOWLOCATION, 1);
       curl_setopt($this->ch, CURLOPT_SSL_VERIFYPEER, false);
       curl_setopt($this->ch, CURLOPT_HTTPHEADER,  $headers);
       curl_setopt($this->ch, CURLOPT_COOKIEFILE, $this->cookie_path);
       curl_setopt($this->ch, CURLOPT_COOKIEJAR, $this->cookie_path);
       curl_setopt($this->ch, CURLOPT_POST, TRUE);
       curl_setopt($this->ch, CURLOPT_POSTFIELDS, $datas);
       curl_setopt($this->ch, CURLINFO_HEADER_OUT, 1);

       $result = json_decode(curl_exec($this->ch));
       echo curl_error($this->ch);
       $info = curl_getinfo($this->ch);
       var_dump($info);
       curl_close($this->ch);
       var_dump($result);
 }

所以我没有错误，但输出的标题如下： GET / HTTP/1.1 用户代理：Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624 Netscape/7.1 (ax), Mozilla Host: test.com Accept: / 连接：Keep-Alive 内容类型：application/x-www-form-urlencoded

为什么标头使用 GET 而没有 POST ？ 你能帮帮我吗？

亲切的问候

我不确定我是否理解所有问题，但我可以向您展示 cURL 请求和响应的样子。 POST 方法请求不关心用户代理。看看这对你是否有意义。我刚刚将信息发送到我的请求反射器。你可以在这里看到它的实际效果： https://iconoun.com/demo/temp_f42.php

error_reporting(E_ALL);
echo '<pre>';


// FROM THE POST AT STACK
function action($key, $file){
    $this_agent = NULL; // NOT IMPORTANT WITH POST REQUEST
    $this_cookie_path = 'cookie.txt';

       $this_ch = curl_init();
       $headers[] = "Accept-Encoding: gzip";
       $headers[] = "Connection: Keep-Alive";
       $headers[] = "Content-Type: application/x-www-form-urlencoded";

       $datas = "arg=test&action=upload";
       curl_setopt($this_ch, CURLOPT_URL, "https://iconoun.com/demo/request_reflector.php");
       curl_setopt($this_ch, CURLOPT_USERAGENT, $this_agent);
       curl_setopt($this_ch, CURLOPT_RETURNTRANSFER, 1);
       curl_setopt($this_ch, CURLOPT_FOLLOWLOCATION, 1);
       curl_setopt($this_ch, CURLOPT_SSL_VERIFYPEER, false);
       curl_setopt($this_ch, CURLOPT_HTTPHEADER,  $headers);
       curl_setopt($this_ch, CURLOPT_COOKIEFILE, $this_cookie_path);
       curl_setopt($this_ch, CURLOPT_COOKIEJAR, $this_cookie_path);
       curl_setopt($this_ch, CURLOPT_POST, TRUE);
       curl_setopt($this_ch, CURLOPT_POSTFIELDS, $datas);
       curl_setopt($this_ch, CURLINFO_HEADER_OUT, 1);

       $result = curl_exec($this_ch);
       echo curl_error($this_ch);
       $info = curl_getinfo($this_ch);
       var_dump($info);
       curl_close($this_ch);
       var_dump($result);
 }

 action(NULL, NULL);

响应看起来像这样......
