CURL POST 请求 返回 Length Required

[eoo]

我就纳闷了，头一次出现这问题，百度过了找不到相关问题的解决办法。

携带 cookie GET 请求普通页面倒是没问题， 加了 POST 请求签到地址就返回

Length Required

HTTP Error 411. The request must be chunked or have a content length.


我以为是缺少了 Content-Length 头

就 strlen data 长度加了 header 提交 还是这样。

怎么解决？

ini_set ('display_errors','on');
error_reporting (E_ALL );

//限制内存占用
ini_set ('memory_limit','10M');



//普通 URL 地址
$url="http://xin123.cc/bbs/book_list.aspx?action=new&siteid=1000";

//签到地址

$ch = curl_init ();

以上代码测试得到
HTTP/1.1 200 OK
Cache-Control: no-cache
Pragma: no-cache
Content-Length: 11900

（内容略）

于是问题在哪？
