【问题描述】：
我正在尝试将 facebook 集成添加到我正在使用 cordova 构建的 ionic 移动应用程序中。我可以让它在没有cordovaa或angular的情况下工作，但两者都没有。使用下面的代码，一切都很好，直到加载 all.js 后调用 FB.init 。之后，_init 函数内不再执行任何代码，因此我无法订阅事件或做任何其他事情。
angular facebook 指令（使用来自此要点的代码：https://gist.github.com/ruiwen/4722499）
angular.module('facebook', [])
.directive('fb', ['$FB', function($FB) {
return {
restrict: "E",
replace: true,
template: "<div id='fb-root'></div>",
compile: function(tElem, tAttrs) {
return {
post: function(scope, iElem, iAttrs, controller) {
var fbAppId = iAttrs.appId || '';
var fb_params = {
appId: iAttrs.appId || "",
cookie: iAttrs.cookie || true,
status: iAttrs.status || true,
nativeInterface: CDV.FB,
useCachedDialogs: false,
xfbml: iAttrs.xfbml || true
};
// Setup the post-load callback
window.fbAsyncInit = function() {
$FB._init(fb_params);
if('fbInit' in iAttrs) {
iAttrs.fbInit();
}
};
(function(d, s, id, fbAppId) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk', fbAppId));
}
}
}
};
}])
.factory('$FB', ['$rootScope', function($rootScope) {
var fbLoaded = false;
// Our own customisations
var _fb = {
loaded: fbLoaded,
isLoaded : function(){
return this.loaded;
},
authenticated : false,
isAuthenticated : function(){
return this.authenticated;
},
statusUpdated: function(response){
if (response.status == 'connected') {
self.authenticated = true;
alert('logged in');
} else {
alert('not logged in');
}
},
_init: function(params) {
self = this;
if(window.FB) {
// FIXME: Ugly hack to maintain both window.FB
// and our AngularJS-wrapped $FB with our customisations
angular.extend(window.FB, this);
angular.extend(this, window.FB);
// Set the flag
this.loaded = true;
// Initialise FB SDK
FB.init(params);
//THIS CODE IS NOT CALLED
FB.Event.subscribe('auth.statusChange', function(response) {
alert('auth.statusChange event');
});
FB.Event.subscribe('auth.authStatusChange', self.statusUpdated)
if(!$rootScope.$$phase) {
$rootScope.$apply();
}
}
}
}
return _fb;
}]);
我的控制器：
angular.module('starter.controllers', [])
.controller('StartCtrl', [
'$scope',
'$FB',
'$location',
function($scope, $FB, $location) {
$scope.$watch(function() {
return $FB.isLoaded()
},function(value){
console.log("VALUE",value);
// It needs authentication, this won't work.
if(value){
$scope.facebook_friends = $FB.api('/me/friends', function(response) {
$scope.facebook_friends = response.data;
});
}
},true);
$scope.$watch(function() {
return $FB.isAuthenticated()
},function(value){
alert("VALUE isAuthenticated "+value);
// YEP, this will work.
if(value){
$scope.facebook_friends = $FB.api('/me', function(response) {
$scope.facebook_friends = response.data;
console.log("FRIENDS",response);
});
}
},true);
$scope.FBlogin = function() {
FB.login(null, {scope: 'email'});
};
}
])
index.html：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="initial-scale=0.5, maximum-scale=0.5, user-scalable=no, width=device-width">

</head>
<body ng-app="starter" animation="slide-left-right-ios7">
<ion-nav-view></ion-nav-view>
<fb app-id='appid'></fb>
</body>
</html>
和 app.js
angular.module('starter', ['ionic', 'starter.services', 'starter.controllers', 'facebook'])
.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('start', {
url: "/start",
templateUrl: "templates/start.html",
controller: 'StartCtrl'
})
// if none of the above states are matched, use this as the fallback
$urlRouterProvider.otherwise('/start');
});
