PHP的捲曲發送信息，以滿足隱藏輸入

Question

我試圖登錄到它具有以下形式的網站：

<div class="inner"> 
     <form name="loginform" action="/site/?module=account&action=login&return_url=" method="post"> 
     <input type="hidden" name="server" value="nice"> 
     <div class="inputs"> 
      <div class="user"> 
       <input style="width: 108px;" id="login_user" type="text" name="username" value="username" onfocus="inputFocus(this)" onblur="inputBlur(this)" /> 
      </div> 
      <div class="pass"> 
       <input style="width: 108px;" id="login_pass" type="password" name="password" value="password" onfocus="inputFocus(this)" onblur="inputBlur(this)" /> 
       <input type="submit" style="visibility:hidden"/> 
      </div> 
     </div> 
     <div class="submit"> 
      <div class="submit-btn" onclick="document.loginform.submit();"></div> 
     </div> 
     <div class="clear"></div> 
     <div class="links"> 
      <a href="/site/?module=account&action=resetpass">Forgot Password?</a> 
     </div> 
    </form> 

</div> 

使用這個PHP腳本：

<?php 
$username=""; 
$password=""; 
$url="(handled this)"; 
$cookie="cookie.txt"; 

$postdata = "username=".$username."&password=".$password; 

$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_URL, $url); 
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 
curl_setopt ($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 0); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie); 
curl_setopt ($ch, CURLOPT_REFERER, $url); 

curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata); 
curl_setopt ($ch, CURLOPT_POST, 1); 
$result = curl_exec ($ch); 

echo $result; 
curl_close($ch); 

?> 

將輸出：

Invalid login server selected, please try again with a valid server. 

因爲我沒有滿足隱藏的輸入。 我試圖在谷歌搜索，但我看不到一個PHP腳本，應該爲此工作。 對不起，我在課堂上沒有教過cURL。

將服務器添加到您的$ postdata。

順便說一句：你需要urlencode參數名稱和參數值。
