使用CURL和PHP连接到简单机器论坛

Question

以下是我尝试登录

的smf登录表单的来源

 <form id="guest_form" action="http://example.com/index.php?action=login2" method="post" accept-charset="UTF-8"  onsubmit="hashLoginPassword(this, '828560f91ef51ab12e80def32be06ad4');">
                        <div class="info">Please <a href="http://example.com/index.php?action=login">login</a> or <a href="http://example.com/index.php?action=register">register</a>.</div>
                        <input type="text" name="user" size="10" class="input_text" />
                        <input type="password" name="passwrd" size="10" class="input_password" />
                        <select name="cookielength">
                            <option value="60">1 Hour</option>
                            <option value="1440">1 Day</option>
                            <option value="10080">1 Week</option>
                            <option value="43200">1 Month</option>
                            <option value="-1" selected="selected">Forever</option>
                        </select>
                        <input type="submit" value="Login" class="button_submit" /><br />
                        <div class="info">Login with username, password and session length</div>
                        <input type="hidden" name="hash_passwrd" value="" />
                    </form>

这是我想出的PHP代码：

<?php
$user = "test"; 
$pass = "test"; 
$url="http://www.jasper88.5gbfree.com/index.php?action=login2"; 


$curl_useragent = 'Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.8.1.11) Gecko/20071127 Firefox/2.0.0.11';
$curl_httpheader = array( 'Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5',
'Accept-Language: en-us,en;q=0.5',
'Accept-Encoding: gzip,deflate',
'Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7' );
$referer = "http://www.jasper88.5gbfree.com";




$postdata = "user=$user&passwrd=$pass&cookielength=-1&submit=Login";


$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_FAILONERROR, false );
curl_setopt ($ch, CURLOPT_TIMEOUT, false );
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, false );
curl_setopt ($ch, CURLOPT_USERAGENT, $curl_useragent );
curl_setopt ($ch, CURLOPT_REFERER, $referer);
curl_setopt ($ch, CURLOPT_COOKIESESSION, true );
curl_setopt ($ch, CURLOPT_URL, $url);  
curl_setopt ($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, true); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt ($ch, CURLOPT_COOKIEJAR, "/cok4.txt"); 
curl_setopt ($ch, CURLOPT_COOKIEFILE, "/cok4.txt"); 
curl_setopt ($ch, CURLOPT_VERBOSE, true); 
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata); 
curl_setopt ($ch, CURLOPT_POST, true); 
$result = curl_exec ($ch); 


echo $result;
if (curl_error($ch)) {
    echo curl_error($ch);
}






?>

我收到此错误：会话验证失败。请尝试注销并重新登录，然后重试。

任何人都可以帮助我吗？服务器是我的，如果你想尝试代码，登录工作。
