使用PHP的cURL lib中的POST不发送

$ch = curl_init();
curl_setopt($ch,CURLOPT_HEADER,true);
curl_setopt($ch,CURLOPT_HTTPHEADER,$header);
curl_setopt($ch,CURLINFO_HEADER_OUT,CURLOPT_SSL_VERIFYPEER,0);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,false);
curl_setopt($ch,CURLOPT_POST,CURLOPT_POSTFIELDS,$data);
curl_setopt($ch,CURLOPT_URL,$url);
$t = curl_exec($ch);

不知道为什么,但我正在尝试登录页面,当我转储$t时,我总是看到表单,curl_error是空的,我该怎么做才能调试这个？试图登录的页面不是我的！

我有一个模拟cURL的本地表单,它可以：

<form action="$url" method="POST">
  <input type="hidden" name="username" value="$uspw" />
  <input type="hidden" name="password" value="$uspw" />
  <input type="submit" value="Send" />
</form>

它登录$url！这是我在cURL中发送给POSTFIELDS的$data

$data = array('username' => $uspw,'password' => $uspw);

是..用户和密码是一样的

标题收到：

HTTP/1.1 100 Continue

HTTP/1.1 200 OK

X-Powered-By: Servlet/2.4 JSP/2.0
Content-Type: text/html; charset=ISO-8859-1

在此之后我再次收到所有表格……

$data = array('username' => $uspw,'password' => $uspw);


$header = array('Origin: xxx','Content-Type: application/x-www-form-urlencoded','Connection: keep-alive','Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3','Cache-Control: max-age=0','Except:','Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8','Accept-Charset:ISO-8859-1,'Accept-Encoding:gzip,deflate,sdch','Accept-Language:es-ES,es;q=0.8',);

$ch = curl_init();
curl_setopt($ch,1);

curl_setopt($ch,CURLOPT_FORBID_REUSE,CURLOPT_FRESH_CONNECT,CURLOPT_AUTOREFERER,CURLOPT_USERAGENT,"Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.11 (KHTML,like Gecko) Chrome/23.0.1271.64 Safari/537.11");
curl_setopt($ch,CURLOPT_COOKIEJAR,'xxx.txt');
curl_setopt($ch,CURLOPT_REFERER,'xxxx');
curl_setopt($ch,$url);
$t = curl_exec($ch);

谢谢！
