php – 如何使用POST和Cookie登录cURL

我不知道需要什么信息才能显示所有信息：

登录表格：

<div id="loginForm">
 <div id="logo"><img src="logo.png" border="0" /></div>
 <div class="loginBar">Login</div>
  <form action="index.php" method="post">
    <input type="hidden" name="p" value="login" />
    <div class="line">
      <label>Captcha</label>
      <img src="captcha/securimage_show.php" border="0" />
    </div>
    <div class="line">
      <label>&nbsp;</label>
      <input type="text" name="captcha" value=""/>                
    </div>
    <div class="line">
      <label>&nbsp;</label>
      <input type="submit" value="Login" />
    </div>
  </form>                        
 <hr/>
 <a href="index.php?p=register" class="register" title="Click to register">Register</a>
</div>

cURL代码：

extract($_POST);

    //set POST variables
    $proxy = '127.0.0.1:8118';
    $url = 'http://example.com/index.php';
    $fields_string= 'p=login&user=' . $user . '&pass=' . $passwd . '&captcha=' . $_POST['captcha'] . '&submit=Login';

        //open connection
        $ch = curl_init();

        //set the url,number of POST vars,POST data
        curl_setopt($ch,CURLOPT_URL,$url);
        curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);
        curl_setopt($ch,CURLOPT_USERAGENT,"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
        curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);
        curl_setopt($ch,CURLOPT_PROXY,$proxy);
        curl_setopt($ch,CURLOPT_COOKIEJAR,"cookie.txt");
        curl_setopt($ch,CURLOPT_COOKIEFILE,"cookie.txt");
    //curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
        //execute post
        $result = curl_exec($ch);

        print_r(curl_error($ch));
        print_r(curl_getinfo($ch));
        print_r(curl_errno($ch));

        //close connection
        curl_close($ch);

curl getinfo：

[url] => http://example.com/index.php 
[content_type] => text/html 
[http_code] => 200

真正的cookie：

由curcurl在cookie.txt中生成的gerenated文件：

# Netscape HTTP Cookie File
# http://curl.haxx.se/rfc/cookie_spec.html
# This file was generated by libcurl! Edit at your own risk.

example.com FALSE   /   FALSE   0   PHPSESSID   crs9cm100agdfsujsncr964jg7

当我运行此代码时,服务器会收到Account,Passwd和Captcha successfull,但是有cookie错误：

Make sure you’ve cookies enabled

此外,我看到真正的cookie内容原始与libcurl生成不同.

此外,我从我的表单中看到我成功捕获了网络服务器cookie.

PS！我以登录表单从此链接收到cookie：

<img src="captcha/securimage_show.php" border="0" />
