【问题描述】:
所以我在我的网站主页上设置了一个基本的登录/身份验证流程。在身份验证对话框之后,我想将它们重定向到我网站上的另一个页面。我已经尝试了现有代码的几种变体,在开发人员应用程序的基本设置下更改站点 url,尝试不同的 oauth 流程,但它仍然只是重定向到他们登录的同一个主页。我知道这听起来非常简单,但是有很多不同的身份验证流程和实现,这有点令人困惑。
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'XXXXXXXXXX', // App ID
channelURL : '//localhost/dataweavr/channel.php', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
oauth : true, // enable OAuth 2.0
xfbml : true // parse XFBML
});
// Additional initialization code here
};
// Load the SDK Asynchronously
(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));
</script>
然后还有更多的乐趣......
<div id="fb-root"></div>
<div id="user-info"></div>
<button id="fb-auth">Login</button>
<script>
window.fbAsyncInit = function() {
FB.init({ appId: 'XXXXXXXXXXXXXXXXXXXXXX',
status: true,
cookie: true,
xfbml: true,
oauth: true});
function updateButton(response) {
var button = document.getElementById('fb-auth');
if (response.authResponse) {
//user is already logged in and connected
var userInfo = document.getElementById('user-info');
FB.api('/me', function(response) {
userInfo.innerHTML = '<img src="https://graph.facebook.com/'
+ response.id + '/picture">' + response.name;
button.innerHTML = 'Logout';
});
button.onclick = function() {
FB.logout(function(response) {
var userInfo = document.getElementById('user-info');
userInfo.innerHTML="";
});
};
} else {
//user is not connected to your app or logged out
button.innerHTML = 'Login';
button.onclick = function() {
FB.login(function(response) {
if (response.authResponse) {
FB.api('/me', function(response) {
var userInfo = document.getElementById('user-info');
userInfo.innerHTML =
'<img src="https://graph.facebook.com/'
+ response.id + '/picture" style="margin-right:5px"/>'
+ response.name;
});
} else {
//user cancelled login or did not grant authorization
}
}, {scope:'email,user_birthday'});
}
}
}
// run once with current status and whenever the status changes
FB.getLoginStatus(updateButton);
FB.Event.subscribe('auth.statusChange', updateButton);
};
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol
+ '//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
</script>
还有另一个不相关的问题。为什么我只有一个正常的按钮弹出窗口?如何让 SDK 呈现 Facebook 登录按钮,而不仅仅是一个简单的登录按钮?
