我有两个功能,都返回承诺:
var getToken = function() {
var tokenDeferred = $q.defer();
socket.on('token', function(token) {
tokenDeferred.resolve(token);
});
//return promise
return tokenDeferred.promise;
}
var getUserId = function() {
var userIdDeferred = $q.defer();
userIdDeferred.resolve('someid');
return userIdDeferred.promise;
}

现在我有一个主题列表,一旦这两个承诺得到解决,我想立即更新
var topics = {
firstTopic: 'myApp.firstTopic.',
secondTopic: 'myApp.secondTopic.',
thirdTopic: 'myApp.thirdTopic.',
fourthTopic: 'myApp.fourthTopic.',
};

已解决的主题应如下所示 myApp.firstTopic.someid.sometoken
var resolveTopics = function() {
$q.all([getToken(), getUserId()])
.then(function(){
//How can I resolve these topics in here?
});
}
