使用PHP curl登录到另一个域

我在两个域中有两个文件

     http://example1.com/remote_login.php

及

当用户访问

http://example1.com/remote_login.php

我想在remote_login.php中进行一些验证，然后我想将

用户名

和

密码

发布到

http://example2.com/login.php

如果结果为成功，则应将用户重定向到

http://example2.com/index.php

（我还在

http://example2.com/index.php

）

有什么想法吗

对不起，我的英语不好

我用

curl

试过了，但不起作用，它会登录，但不会设置会话。所以用户不能重定向到

index.php

$cookie="cookie.txt"; 
$data = array();
$data['global_id'] = "raj";
$data['global_password'] = "raj";

foreach ($data as $key => $value){
    $post_items[] = $key . '=' . $value;
}

//create the final string to be posted using implode()
$post_string = implode ('&', $post_items);


$curl_connection = curl_init('http://example2.com/login.php');
curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30);

curl_setopt($curl_connection, CURLOPT_USERAGENT,"Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:14.0) Gecko/20100101 Firefox/14.0.1");

curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($curl_connection, CURLOPT_FAILONERROR, TRUE);
curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl_connection, CURLOPT_REFERER, 'http://example2.com/login.php');
curl_setopt($curl_connection, CURLOPT_POST, true);
curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $data);
curl_setopt($curl_connection, CURLOPT_HEADER, FALSE);
curl_setopt($curl_connection, CURLOPT_COOKIEJAR, $cookie);
curl_setopt($curl_connection, CURLOPT_COOKIEFILE, $cookie);
curl_setopt($curl_connection, CURLOPT_SSLVERSION, 3); // OpenSSL issue
curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, 0);  // Wildcard certificate
curl_setopt($curl_connection, CURLOPT_SSL_VERIFYHOST, 2);
$result = curl_exec($curl_connection);


if($result){
    header("Location: http://example2.com/index.php");

}
else{
    echo "Login failed";
}

这是一项相当大的任务。用户没有登录的原因是，会话不会在他们的计算机上设置，而是在服务器上设置（如果服务器接受cookies）。因此，您现在所做的是毫无用处的

也就是说，您可以设置某种系统，在这种系统中，每个远程登录都会触发生成某种“验证ID”，然后将其返回给特定用户，然后用户会被重定向到一个链接（

validateSession.php

？），传递特定的ID以确认身份，所有会话都在那里设置

这是一项艰巨的任务

另外请注意：除非您使用SSL来防止中间人攻击，否则这不是100%安全的。中间人攻击是指某个邪恶的怪物监听从客户端发送到服务器的内容，反之亦然。因此，如果有人获得了该ID，您就有麻烦了。或者更糟糕的是，如果他们获得了用户用户名并通过了……哦，天哪……

按原样编码

在if（$result）中更改您的代码

if（$result）{
//java脚本
函数submitform（）//这是使用post方法从数据发送的函数
{
document.forms[“myform”].submit（）；
警报（“值已汇总”）；
}
函数submitform（）；//在页面加载时调用函数
}

i高压解决方案，但其路径很长。
