Cách đăng nhập bằng tài khoản Facebook?

Question

Tôi đã trải qua this link và đã thử mã.

Tôi đang làm điều tương tự nhưng không có phản hồi nào đến từ Facebook. Không có cửa sổ bật lên (không bị chặn). Mã của tôi được cung cấp bên dưới:

<div id="fb-root"></div> 
<script> 


// Additional JS functions here 


window.fbAsyncInit = function() { 


FB.init({ 

     appId  : 'myappid', // App ID 
     channelUrl : '//myurl/channel.html', // Channel File 
     status  : true, // check login status 
     cookie  : true, // enable cookies to allow the server to access the session 
     xfbml  : true // parse XFBML 
    }); 


FB.getLoginStatus(function(response) { 
alert("Response"); 
alert("getloginstatus"); 
    if (response.status === 'connected') { 
     // connected 
    } else if (response.status === 'not_authorized') { 
     // not_authorized 
     login(); 
    } else { 
     // not_logged_in 
     login(); 
    } 
}); 

}; 


    (function(d){ 
    var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0]; 
    if (d.getElementById(id)) {return;} 
    js = d.createElement('script'); js.id = id; js.async = true; 
    js.src = "//connect.facebook.net/en_US/all.js"; 
    ref.parentNode.insertBefore(js, ref); 
    alert("Lodaed SDK"); 
    }(document)); 

function testAPI() { 
    console.log('Welcome! Fetching your information.... '); 
    FB.api('/me', function(response) { 
     alert("Good to see you, " + response.name + "."); 
    }); 
} 

function login() { 
    FB.login(function(response) { 
     if (response.authResponse) { 
      // connected 
     } else { 
      // cancelled 
     } 
    }); 
} 





</script> 
</div> 

Hãy cho tôi biết tôi đang làm gì sai. Tôi không, tôi không có bất kỳ hộp kiểm nào trong số

 <script> 
     // This is called with the results from from FB.getLoginStatus(). 
     function statusChangeCallback(response) { 
     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. 
      console.log("The person is logged into Facebook, but not your app."); 
     } else { 
      // The person is not logged into Facebook, so we're not sure if 
      // they are logged into this app or not. 
     } 
     } 

     // 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: 'v2.2' // use version 2.2 
     }); 

     // 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("Fb response"); 
      console.log(response); 
      console.log('Successful login for: ' + response.name); 
      document.getElementById('status').innerHTML = 
      'Thanks for logging in, ' + response.name + '!'; 
     }); 
     } 
     </script> 

Trong cơ thể, sử dụng: -

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