ユーザーがアプリに初めてアクセスすると、すべて正常に動作します。ユーザーは、アプリを承認するための質問を含むポップアップを受け取ります。しかし、次のセッション (例: 更新) で、空のポップアップが表示され、すぐに閉じます。
Facebook が新しいアクセス トークンを要求していると思いますが、ユーザー フレンドリーではないことが問題です。ポップアップが開いたり閉じたりすると、ユーザーは何かがおかしい、または何かを見逃したと思います。
コードは次のとおりです。
window.fbAsyncInit = function() {
FB.init({
appId : '', // App ID
channelUrl : '', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
// Here we subscribe to the auth.authResponseChange JavaScript event. This event is fired
// for any authentication related change, such as login, logout or session refresh. This means that
// whenever someone who was previously logged out tries to log in again, the correct case below
// will be handled.
FB.Event.subscribe('auth.authResponseChange', function(response) {
// Here we specify what we do with the response anytime this event occurs.
if (response.status === 'connected') {
// The response object is returned with a status field that lets the app know the current
// login status of the person. In this case, we're handling the situation where they
// have logged in to the app.
if(accessToken)
{
//console.log("Connected WITH accesToken");
testAPI();
}
else{
// console.log("Connected WITHOUTaccesToken");
FB.login(function(response) {
// handle the response
uid = response.authResponse.userID;
accessToken = response.authResponse.accessToken;
//console.log(uid);
//console.log(accessToken);
}, {scope: 'friends_location, user_location, user_relationships'});
}
} else if (response.status === 'not_authorized') {
// In this case, the person is logged into Facebook, but not into the app, so we call
// FB.login() to prompt them to do so.
// In real-life usage, you wouldn't want to immediately prompt someone to login
// like this, for two reasons:
// (1) JavaScript created popup windows are blocked by most browsers unless they
// result from direct interaction from people using the app (such as a mouse click)
// (2) it is a bad experience to be continually prompted to login upon page load.
//alert("You're logged in on FB but not on the APP");
FB.login();
} else {
// In this case, the person is not logged into Facebook, so we call the login()
// function to prompt them to do so. Note that at this stage there is no indication
// of whether they are logged into the app. If they aren't then they'll see the Login
// dialog right after they log in to Facebook.
// The same caveats as above apply to the FB.login() call here.
// FB.login();
//alert("You're offline on FB");
FB.login();
}
});
};
// Load the SDK asynchronously
(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);
}(document));
// Here we run a very simple test of the Graph API after login is successful.
// This testAPI() function is only called in those cases.
function testAPI() {
FB.api('/'+uid+'/friends?fields=name,location,picture&accesstoken='+accessToken, function(response) {
}
//<img border="0" src="console.log(response.data[0].picture.data.url)">
}
});
}
//Logout
function fbLogout() {
//FB.init();
FB.logout(function (response) {
//Do what ever you want here when logged out like reloading the page
//window.location.reload();
});
}
この空のポップアップを防ぐにはどうすればよいですか?
