如何使用 Jquery 或 PHP 从其他网站获得响应？

Question

我有一个问题

我需要制作一个登录表单，我必须从其他网站获得响应，我知道有 HttpResponseMessage，但我认为这是为了消耗网络 API，所以我真的很想知道如何获得网站的响应，因为我需要成功登录或者登录失败

有什么方法可以做到吗？

和代码：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
 <script>
  $(document).ready(function(){
   $("#btnSub").click(function(){
    if($("#User").val() == "" || $("#Pass").val() == ""){
     alert("Insert User & Password");
     event.preventDefault();
    }else{
     $("#LogBox").hide();
    }
    
   }); 
  });
 
 </script>

<section class="container">
     <div class="login">
      <h1>Inicio de Sesión</h1>
      <form action="http://us.mzoneweb.net/Scope.MZone.Web/Logon.ashx" method="post" target="TheMZoneFrame">
       <p><input name="Username" id="User" type="text" placeholder="Usuario"></p>
       <p><input name="Password" id="Pass" type="password" placeholder="Contraseña"></p>
       <p><input name="LogoutUrl" type="hidden" value=""></p>
       <p><input name="ErrorUrl" type="hidden" value=""></p>
       <p><input name="Version" type="hidden" value=""></p>
            
       <p class="remember_me">
       <label>
       <input type="checkbox" name="remember_me" id="remember_me">
       Remember me on this computer
       </label>
       </p>
       <p class="submit"><input name="Submit1" id="btnSub" type="submit" value="Iniciar Sesión" ></p>
      </form>
     </div>
    </section>

使用cURL.

这是一个示例函数，它将从另一个站点获得响应：

/*
 * Makes an HTTP request via GET or POST, and can download a file
 * @returns - Returns the response of the request
 * @param $url - The URL to request, including any GET parameters
 * @param $params - An array of POST values to send
 * @param $filename - If provided, the response will be saved to the 
 *    specified filename
 */
function request($url, $params = array(), $filename = "") {
    $ch = curl_init();
    $curlOpts = array(
        CURLOPT_URL => $url,
        // Set Useragent
        CURLOPT_USERAGENT => 
            'Mozilla/5.0 (Windows NT 6.3; WOW64; rv:29.0) 
                    Gecko/20100101 Firefox/29.0',
        // Don't validate SSL 
        // This is to prevent possible errors with self-signed certs
        CURLOPT_SSL_VERIFYPEER => false,
        CURLOPT_SSL_VERIFYHOST => false,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_FOLLOWLOCATION => true
    );
    if(!empty($filename)){
        // If $filename exists, save content to file
        $file2 = fopen($filename,'w+') 
            or die("Error[".__FILE__.":".__LINE__."] 
                    Could not open file: $filename");
        $curlOpts[CURLOPT_FILE] = $file2;
    }
    if (!empty($params)) {
        // If POST values are given, send that shit too
        $curlOpts[CURLOPT_POST] = true;
        $curlOpts[CURLOPT_POSTFIELDS] = $params;
    }
    curl_setopt_array($ch, $curlOpts);
    $answer = curl_exec($ch);
    // If there was an error, show it
    if (curl_error($ch)) die(curl_error($ch));
    if(!empty($filename)) fclose($file2);
    curl_close($ch);
    return $answer;
}
