[英]Facebook login API for javascript not working
抱歉,这是一个糟糕的缩进。 这是Facebook登录API。 我在我的javascript编译器中收到这些错误...
无效的应用程序ID:必须是表示应用程序ID的数字或数字字符串。“all.js:53
“在调用FB.init()之前调用了FB.getLoginStatus()。” all.js:53
内容安全策略:无法解析无效的源chrome-extension:// lifbcibllhkdhoafpjfnlhfpfgnpldfl
内容安全策略:无法解析无法识别的源chrome-

获取https://www.facebook.com/plugins/login_button.php [HTTP / 1.1 200 OK 1072ms]“fb:login_button未能在45秒内调整大小”
我肯定有正确的网址和app_id,我的网址是http://myimprint.herokuapp.com/
请任何帮助或指示......

<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : '{283742071785556}',
channelUrl : 'http://myimprint.herokuapp.com/',
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
// Here we subscribe to the auth.authResponseChange JavaScript event. This event is fired
// for any authentication 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.
testAPI();
} 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 interaction from people using the app (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();
}
});
};
// Load the SDK asynchronously
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
// Here we run a very simple test of the Graph API after login is successful.
// This testAPI() function is only called in those cases.
function testAPI() {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
console.log('Good to see you, ' + response.name + '.');
});
}

Invalid App Id: Must be a number or numeric string representing the application id.
改变这一行:
appId : '{283742071785556}',
至:
appId : "283742071785556", /* numeric string */
要么
appId : 283742071785556, /* number */
appId : '283742071785556',
必须解决问题
作为字符串的App ID肯定是主要问题,但还有一个非常重要的事情:您应该始终在鼠标事件监听器中使用FB.login。 这就是为什么:
顺便说一句,如果你将FB.login与JavaScript SDK一起使用,你真的不需要“fb:login-button”按钮。
window.fbAsyncInit = function() {
// for js api initialization
FB.init({
appId : '{Your-16 digit App ID}',
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true, // parse XFBML
oauth : true // enable OAuth 2.0
});
};
要解决此问题,只需在Facebook的“应用”部分中执行“创建新应用”即可。 然后返回Facebook Social Plugins页面,选择一个插件,并为其重新生成代码。
在拥有应用ID之前您的Facebook插件代码:
<div id="fb-root"></div>
<script>(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#xfbml=1";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
将应用程序分配给插件后
<div id="fb-root"></div>
<script>(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#xfbml=1&appId=<your-16-digit-app-id>";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
请注意突出显示的代码中的区别? 如果这在注释区域解决了您的问题,请告诉我。
