我正在使用JSF / Primefaces在Netbeans中构建一个Web应用程序。我选择了FB API / JS SDK，以允许用户登录该应用程序。
我想在成功登录后将用户重定向到另一个页面。
我有一个可以正常工作的XHTML文件。但是，在testAPI()函数中，我添加了window.location.href = 'http://www.google.com';来测试重定向。除非我在登录后手动刷新（F5）页面，否则它将无法正常工作。
这是完整的XHTML，testAPI围绕第91行：

// This is called with the results from from FB.getLoginStatus().
function statusChangeCallback(response) {
console.log('statusChangeCallback');
console.log(response);
// The response object is returned with a status field that lets the
// app know the current login status of the person.
// Full docs on the response object can be found in the documentation
// for FB.getLoginStatus().
if (response.status === 'connected') {
// Logged into your app and Facebook.
//window.location.href = 'http://www.google.com'; //Will take you to Google.
testAPI();
} else {
// The person is not logged into your app or we are unable to tell.
document.getElementById('status').innerHTML = 'Please log ' +
'into this app.';
}
}
// This function is called when someone finishes with the Login
// Button. See the onlogin handler attached to it in the sample
// code below.
function checkLoginState() {
FB.getLoginStatus(function (response) {
statusChangeCallback(response);
});
}
window.fbAsyncInit = function () {
FB.init({
appId: '1943608085935991',
cookie: true, // enable cookies to allow the server to access
// the session
xfbml: true, // parse social plugins on this page
version: 'v3.2' // use graph api version 2.8
});
// Now that we've initialized the JavaScript SDK, we call
// FB.getLoginStatus(). This function gets the state of the
// person visiting this page and can return one of three states to
// the callback you provide. They can be:
//
// 1. Logged into your app ('connected')
// 2. Logged into Facebook, but not your app ('not_authorized')
// 3. Not logged into Facebook and can't tell if they are logged into
// your app or not.
//
// These three cases are handled in the callback function.
FB.getLoginStatus(function (response) {
statusChangeCallback(response);
});
};
// Load the SDK asynchronously
(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 = "https://connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
// Here we run a very simple test of the Graph API after login is
// successful. See statusChangeCallback() for when this call is made.
function testAPI() {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function (response) {
//If I uncomment the line below to redirect, the console logs and
//the getElementById lines won't work
//window.location.href = 'http://www.google.com';
console.log('Successful login for: ' + response.name);
document.getElementById('status').innerHTML =
'Thanks for logging in, ' + response.name + '!';
//If I uncomment the line below, the test api will execute correctly
//except for the windo.location below:
//window.location.href = 'http://www.google.com';
});
}
</script>
<!--
Below we include the Login Button social plugin. This button uses
the JavaScript SDK to present a graphical Login button that triggers
the FB.login() function when clicked.
-->
<!-- I'm trying out these two buttons! -->
<fb:login-button scope="public_profile,email" onlogin="checkLoginState();">
</fb:login-button>
<fb:login-button autologoutlink="true"></fb:login-button>
<div id="status">
</div>
</h:body>
</f:view>
</html>
如您所见，testAPI函数有两行注释，分别对应于我正在尝试的重定向（Google，作为测试）。
我愿意接受替代方案，如果您提出的建议比我正在做的更好，我将完全理解。
如果您要我添加更多信息或其他文件，请告诉我。
非常感谢！
