问题描述:
这是我的代码。它完美的Facebook的JavaScript SDK测试控制台上,而不是在这里:http://www.booktrolley.in/beta/fblogin.phpFacebook JavaScript SDK登录

,我在下面的代码得到一个“日志是未定义”错误:
function onStatus(response) {
Log.info('onStatus', response);
if (response.session) {
showAccountInfo();
} else {
showLoginButton();
}
}
FB.getLoginStatus(function(response) {
onStatus(response); // once on page load
FB.Event.subscribe('auth.statusChange', onStatus); // every status change
});
你想利用一个存在于FB页面上的记录器,但不是你自己的?

试试这个代码:
<html xmlns:fb="http://www.facebook.com/2008/fbml">
<head></head>
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId: '270423476307006',
status: true,
cookie: true,
xfbml: true,
oauth: true
});
FB.getLoginStatus(function(response) {
onStatus(response); // once on page load
FB.Event.subscribe('auth.statusChange', onStatus); // every status change
});
};
(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>
<h1>Login, Logout, Name and Profile Picture</h1>
<div id="account-info"></div>
<script>
/**
* This assumes the user is logged in and renders their profile picture,
* name and a logout link.
*/
function showAccountInfo(resp) {
if(!resp.userID) {
// we shouldn't be here
return;
}
FB.api(
{
method: 'fql.query',
query: 'SELECT name,uid,pic_square FROM user WHERE uid='+resp.userID
},
function(response) {
document.getElementById('account-info').innerHTML = (
'<img src="' + response[0].pic_square + '"> ' +
response[0].name +
' <img onclick="FB.logout()" style="cursor: pointer;"' +
'src="https://s-static.ak.fbcdn.net/rsrc.php/z2Y31/hash/cxrz4k7j.gif">'
);
}
);
}
/**

*/
function showLoginButton() {
document.getElementById('account-info').innerHTML = (
'<img onclick="FB.login()" style="cursor: pointer;"' +
'src="https://s-static.ak.fbcdn.net/rsrc.php/zB6N8/hash/4li2k73z.gif">'
);
}
/**

*/
function onStatus(response) {
if (response.authResponse) {
showAccountInfo(response.authResponse);
} else {
showLoginButton();
}
}

现在让我们来解释一下我们做了什么:
- 我们正在使用异步加载,以确保
FB.getLoginStatus()
将被解雇,只有当库加载成功 - 由于您将
oauth
设置为true,因此您需要更改代码以使用新的响应(请参阅此post)(您可能需要更改应用程序设置) - 基于#2,当前用户ID在使用
showAccountInfo()
将使用可访问response.authResponse.userID
嗨再次:)我仍然认为,从其他的一个它原本指向不同的域调用您的应用程序是问题。尝试在您的应用程序域名“www.booktrolley.in”上创建“pedurology.org”上的相同页面,并查看结果。 – ifaour
@ifaour嗨:D我所有的数据都在pedurology.org上,我的我的应用程序域更改为pedurology.org,正如您所建议的那样,上一个问题已经解决。 但不是这一个。 感谢您的回复:D – Anant
或者您可以将您的网站,域名网址在您的应用设置中更改为“pedurology.org”并尝试使用。 – ifaour
