我试图让用户登录到 facebook,然后在警报中显示他们的用户 ID。
然而,这段代码没有返回任何东西。我究竟做错了什么?
<html>
<head>
<title>Login to Facebook</title>
</head>
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'APP ID',
channelUrl : 'http://www.mydomain.net/zoozTest/channel.html',
status : true,
cookie : true,
xfbml : true,
oauth : true,
});
};
(function(d){
var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
d.getElementsByTagName('head')[0].appendChild(js);
}(document));
//LOGIN FUNCTION
function login() {
FB.login(function(response) {
if (response.authResponse) {
alert('Success!');
}else{
alert('Login Failed!');
}
}, {scope: 'email'});
}
</script>
<div onclick="login();">Login with Facebook</div>
</body>
</html>
