Question

我正在尝试开发Windows 8应用程序，我想将Facebook整合到其中我知道这可以在没有他们的SDK的情况下完成，但我已经看到它也可以用它完成，我很想去使用SDK。

我已经下载并引用了all.js文件。

我在default.html中包含了初始化代码：

    <div id="fb-root"></div>
<script>
    window.fbAsyncInit = function () {
        // init the FB JS SDK
        FB.init({
            appId: '*******',                        // App ID from the app dashboard
            status: true,                                 // Check Facebook Login status
            xfbml: true                                  // Look for social plugins on the page
        });

        // Additional initialization code such as adding Event Listeners goes here
    };
</script>

我正在尝试按下按钮时使用FB.login()登录，但它无效，因为

FB.getLoginStatus(function (response) {
                console.log("entered")
                if (response.status === 'connected') {
                    console.log("connected");

                } else {
                    console.log("connecting");
                    FB.login(function (response) {
                        if (response.authResponse) {
                            console.log("connected");
                        } else {
                            console.log("canceled");
                        }
                    });
                }
            });

但是，单击我附加此功能的按钮时没有任何反应。它能是什么？任何帮助表示赞赏，谢谢！

  // This is called with the results from from FB.getLoginStatus().

    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') {

    } else if (response.status === 'not_authorized') {
      // The person is logged into Facebook, but not your app.
      document.getElementById('status').innerHTML = 'Please log ' +

      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      : '197393374008468',

    cookie     : true,  // enable cookies to allow the server to access 
                        // the session
    xfbml      : true,  // parse social plugins on this page
    version    : 'v2.7' // use version 2.2
  });

  // Now that we've initialized the  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 = "https://connect.facebook.net/en_US/all.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  SDK to present a graphical Login button that triggers
  the FB.login() function when clicked.

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