我将脚本添加到 app.js 中
initializeFB: function () {
if (!isFBInitialized.isInitialized) {
FB.init({
appId: 'xxxxxxxxxxxx',
appSecret: 'xxxxxxxxxxxxxxx',
// App ID from the app dashboard
channelUrl: '//mysite//channel.html', // Channel file for x-domain comms
status: true, // Check Facebook Login status
cookie: true, // enable cookies to allow the server to access the session
xfbml: true // Look for social XFBML plugins on the page to be parsed
});
(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/all.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
// Here we subscribe to the auth.authResponseChange JavaScript event. This event is fired
// for any auth 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.
testFBAPI();
} 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 user interaction (such as a mouse click)
// (2) it is a bad experience to be continually prompted to login upon page load.
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();
}
});
isFBInitialized.isInitialized = true;
}
},
并将其称为 viewattached
app.initializeFB();
然后它运作良好
