FB.ui方法'auth.login'不起作用

Question

它不會打開任何東西。

function logIN() 
{ 
    FB.ui({ 
     method: 'auth.login', 
     perms: 'email', 
     display: 'iframe' }, 
     function(response) { 
      /* */ 
     }); 
} 

Answer 1

我認爲，這應該是你的函數：

FB.ui({ 
    method: 'oauth', 
    display: 'popup', 
    scope: 'email', 
    response_type: 'token', 
    redirect_uri: 'WHEREYOUWANTTOPROCESSTOKEN', 
    client_id: 'YOURAPPID', 
}); 

請注意，只有page或popup是有效類型display

這個例子可能會有幫助：http://fbrell.com/auth/login-and-logout

<button id="fb-auth">Login</button> 

<script> 
function updateButton(response) { 
    console.log('Updating Button', response); 
    var button = document.getElementById('fb-auth'); 

    if (response.session) { 
    button.innerHTML = 'Logout'; 
    button.onclick = function() { 
     FB.logout(function(response) { 
     console.log('FB.logout callback', response); 
     }); 
    }; 
    } else { 
    button.innerHTML = 'Login'; 
    button.onclick = function() { 
     FB.login(function(response) { 
     console.log('FB.login callback', response); 
     if (response.session) { 
      console.log('User is logged in'); 
     } else { 
      console.log('User is logged out'); 
     } 
     }); 
    }; 
    } 
} 

// run it once with the current status and also whenever the status changes 
FB.getLoginStatus(updateButton); 
FB.Event.subscribe('auth.statusChange', updateButton); 
</script>
