服务器成功接收登录名、密码和验证码。我该如何用 cookie 来做到这一点？
我不知道需要什么信息来帮助我将显示全部：
登录表单：
<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> </label>
<input type="text" name="captcha" value=""/>
</div>
<div class="line">
<label> </label>
<input type="submit" value="Login" />
</div>
</form>
<hr/>
<a href="index.php?p=register" class="register" title="Click to register">Register</a>
</div>
卷曲代码：
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);

libcurl 在 cookie.txt 中生成的文件：

当我运行此代码时，服务器成功接收帐户、密码和验证码，但 cookie 出现错误：
确保您已启用 cookie
我还看到真正的 cookie 内容原始与使用 libcurl 生成的不同。
我还从我的表单中看到我成功捕获了网络服务器 cookie。
附注！！我从登录表单中的此链接收到 cookie：
<img src="captcha/securimage_show.php" border="0" />
