如何将Facebook登录与Struts2集成？

Question

I know there are two methods to integrate facebook login with a Java application: 我知道将facebook登录与Java应用程序集成有两种方法：

1) Using Facebook code (JavaScript) 1）使用Facebook代码（JavaScript）

I could use the Facebook provided code blew to allow users to login but the problem is that, I am not sure how to send user's details to the back-end.If I use Javascript function to send response object to back-end it can be accessible by hackers (lets say I use Ajax to send email of logged in user to back-end). 我可以使用Facebook 提供的代码自爆允许用户登录，但问题是，我不知道如何将用户的详细信息发送到后端。如果我使用Javascript函数将响应对象发送到后端它可以是黑客可以访问（假设我使用Ajax将登录用户的电子邮件发送到后端）。 Is there any other way to do it? 还有其他办法吗？

2)Spring Social - Facebook 2）Spring Social - Facebook

I know I can use Spring Social , but the problem is that it is based on Spring Web framework and it seems it is difficult to integrate it with Struts2, as it is using annotations such as /connect/facebook. 我知道我可以使用Spring Social ，但问题是它基于Spring Web框架，似乎很难将它与Struts2集成，因为它使用的是/ connect / facebook等注释。 and redirect code such as 和重定向代码，如

<!DOCTYPE html>
<html>
<head>
<title>Facebook Login JavaScript Example</title>
<meta charset="UTF-8">
</head>
<body>
<script>
  // This is called with the results from from FB.getLoginStatus().
  function statusChangeCallback(response) {
    console.log('statusChangeCallback');
    console.log(response);
    // The response object is returned with a status field that lets the
    // app know the current login status of the person.
    // Full docs on the response object can be found in the documentation
    // for FB.getLoginStatus().
    if (response.status === 'connected') {
      // Logged into your app and Facebook.
      testAPI();
    } else if (response.status === 'not_authorized') {
      // The person is logged into Facebook, but not your app.
      document.getElementById('status').innerHTML = 'Please log ' +
        'into this app.';
    } else {
      // The person is not logged into Facebook, so we're not sure if
      // they are logged into this app or not.
      document.getElementById('status').innerHTML = 'Please log ' +
        'into Facebook.';
    }
  }

  // This function is called when someone finishes with the Login
  // Button.  See the onlogin handler attached to it in the sample
  // code below.
  function checkLoginState() {
    FB.getLoginStatus(function(response) {
      statusChangeCallback(response);
    });
  }

  window.fbAsyncInit = function() {
  FB.init({
    appId      : '{your-app-id}',
    cookie     : true,  // enable cookies to allow the server to access 
                        // the session
    xfbml      : true,  // parse social plugins on this page
    version    : 'v2.0' // use version 2.0
  });

  // Now that we've initialized the JavaScript SDK, we call 
  // FB.getLoginStatus().  This function gets the state of the
  // person visiting this page and can return one of three states to
  // the callback you provide.  They can be:
  //
  // 1. Logged into your app ('connected')
  // 2. Logged into Facebook, but not your app ('not_authorized')
  // 3. Not logged into Facebook and can't tell if they are logged into
  //    your app or not.
  //
  // These three cases are handled in the callback function.

  FB.getLoginStatus(function(response) {
    statusChangeCallback(response);
  });

  };

  // Load the SDK asynchronously
  (function(d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id)) return;
    js = d.createElement(s); js.id = id;
    js.src = "//connect.facebook.net/en_US/sdk.js";
    fjs.parentNode.insertBefore(js, fjs);
  }(document, 'script', 'facebook-jssdk'));

  // Here we run a very simple test of the Graph API after login is
  // successful.  See statusChangeCallback() for when this call is made.
  function testAPI() {
    console.log('Welcome!  Fetching your information.... ');
    FB.api('/me', function(response) {
      console.log('Successful login for: ' + response.name);
      document.getElementById('status').innerHTML =
        'Thanks for logging in, ' + response.name + '!';
    });
  }
</script>

<!--
  Below we include the Login Button social plugin. This button uses
  the JavaScript SDK to present a graphical Login button that triggers
  the FB.login() function when clicked.
-->

<fb:login-button scope="public_profile,email" onlogin="checkLoginState();">
</fb:login-button>

<div id="status">
</div>

</body>
</html>
