php cURL - 请求必须分块或具有内容长度

Question

今天我在尝试使用“lib cURL”时遇到了这个奇怪的错误，我找不到解决方案，你能帮我解决这个问题吗？

<?php
set_time_limit(0);
  class cURL
  {
  var $content;
  var $cookie;
  var $headers = array();
  var $ch;
  var $data;
  var $info;
  var $httpcode;
  var $proxy_ip;
  var $proxy_port;
  var $cookie_f;

  function __construct($cookie = '')
  {
      if (!empty($cookie)) {
          $this->cookie_f = $cookie;
      }
  }

  function setproxy($proxy)
  {
      list($ip, $porta) = explode(":", $proxy);
      $this->proxy_ip = $ip;
      $this->proxy_port = $porta;
  }

  function setcookie($cookie)
  {
      $this->cookie = $cookie;
  }

  function open($type, $url)
  {
      $this->ch = curl_init();
      curl_setopt($this->ch, CURLOPT_URL, $url);      
      curl_setopt($this->ch, CURLOPT_FOLLOWLOCATION, 1);
      curl_setopt($this->ch, CURLOPT_RETURNTRANSFER, 1);
      curl_setopt($this->ch, CURLOPT_SSL_VERIFYPEER, false);
      curl_setopt($this->ch, CURLOPT_HEADER, true);
      //curl_setopt($this->ch, CURLOPT_HTTPHEADER, array("Content-type: application/x-www-form-urlencoded", "Content-length: 216"));
      curl_setopt($this->ch, CURLOPT_ENCODING, "");
      curl_setopt($this->ch, CURLOPT_COOKIEFILE, getcwd() . '/cookies.cookie');
      curl_setopt($this->ch, CURLOPT_COOKIEJAR, getcwd() . '/cookies.cookie');
      curl_setopt($this->ch, CURLOPT_USERAGENT, "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; pt-BR; rv:1.9.2.18) Gecko/20110614 Firefox/3.6.18");

      if (strtolower($type) == 'post') {
          curl_setopt($this->ch, CURLOPT_CUSTOMREQUEST, "POST");
          curl_setopt($this->ch, CURLOPT_POST, 1);
          curl_setopt($this->ch, CURLOPT_POSTFIELDS, $this->data);
          curl_setopt($this->ch, CURLOPT_HEADER, true);
      }

      $this->content = curl_exec($this->ch);
      curl_close($this->ch);
      return $this->content;

  }
  }

?>
<?php
    $curll = New cURL;
    $curll ->setCookie = "cookies.cookie";
    $curll ->data = "username=user&password=pass&IsSyncUp=&FacebookAssociation=&SNAccessToken=";
    $curll ->open("POST", "http://www.website.com");
    $curll ->data = '__EVENTTARGET=ctl00$ctl00$cphRoblox$cphMyRobloxContent$lbSend&ctl00$ctl00$cphRoblox$cphMyRobloxContent$rbxMessageEditor$txtSubject=AAAAAAAAA&ctl00$ctl00$cphRoblox$cphMyRobloxContent$rbxMessageEditor$txtBody=BBBBBBBBB';
    $curll ->open("POST", "http://www.website.com/My/PrivateMessage.aspx?RecipientID=20815603");
    echo $curll ->content;
?>

所以，我返回的错误是:

HTTP/1.1 302 Found Cache-Control: private Content-Type: text/html; charset=utf-8 Location: /Login/Default.aspx?ReturnUrl=%2fMy%2fPrivateMessage.aspx%3fRecipientID%3d20815603&RecipientID=20815603 Server: Microsoft-IIS/7.0 Set-Cookie: rbx-ip=; path=/; HttpOnly Set-Cookie: RBXSource=rbx_acquisition_time=10/14/2011 3:32:12 PM&rbx_acquisition_referrer=http://www.website.com/My/PrivateMessage.aspx?RecipientID=20815603&rbx_medium=Direct&rbx_source=www.website.com&rbx_campaign=&rbx_send_info=0; expires=Sun, 13-Nov-2011 21:32:12 GMT; path=/ X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET P3P: CP="CAO DSP COR CURa ADMa DEVa OUR IND PHY ONL UNI COM NAV INT DEM PRE" Date: Fri, 14 Oct 2011 20:32:12 GMT Content-Length: 224 HTTP/1.1 411 Length Required Content-Type: text/html; charset=us-ascii Server: Microsoft-HTTPAPI/2.0 Date: Fri, 14 Oct 2011 20:32:12 GMT Connection: close Content-Length: 344
Length Required HTTP Error 411. The request must be chunked or have a content length.

所以我的问题是“请求必须分块或具有内容长度”。我的 POST 是通过使用“实时 HTTP header ”(Mozila) 查阅浏览器帖子制作的

如果我评论秒数据并打开/发布它工作正常。秒数据和打开/发布是问题所在。

有人能帮帮我吗？感谢阅读。

除非您看到正在传递的实际数据，否则很难确切知道正在发送什么。

下载 fiddler web 代理并比较确切的浏览器输出与 curl。

添加这行 PHP 代码以通过 fiddler 传递 curl。

curl_setopt($ch, CURLOPT_PROXY, '127.0.0.1:8888');
