AngularJS socket.io事件与递延承诺转发 [英] AngularJS socket.io event forwarding with deferred promise
本文介绍了AngularJS socket.io事件与递延承诺转发的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我使用角插座-IO 但需要一种方法的验证应用程序首先启动socket.io接口之前。 我跟着这个方法。
但我需要使用事件转发在工厂如下所示是这样的:
socket.forward(事件);
我如何加入我厂转发?
.factory('插座',函数($ rootScope,$超时的SocketFactory,$ Q $日志){
//创建一个承诺实例
变种插座= $ q.defer();
//侦听的rootScope发出的认证活动
//将角应用。一旦事件被触发,创建套接字和解决
// 承诺。
$ rootScope。在$('认证',函数(){ //决心另一个摘要周期
$超时(函数(){
VAR令牌= window.localStorage [socket_token];
VAR token_query ='令牌='+令牌;
VAR newSocket =(函数(){
返回的SocketFactory({
ioSocket:io.connect('http://example.com:3000',{
查询:token_query
})
});
})();
socket.resolve(newSocket);
});
});
返回socket.promise
});
解决方案
您可以简单地将呼叫添加到向前()
之前解决与创建的插座承诺:
newSocket =(函数(){/ * ... * /})()
newSocket.forward(事件);
socket.resolve(newSocket);
I am using angular-socket-io but needed a way to authenticate in the app first before starting the socket.io interface. I followed this method.
But I need to use event forwarding in the factory as shown here like this:
socket.forward("event");
How can I add forwarding in my factory?
.factory('socket', function($rootScope, $timeout, socketFactory, $q, $log) {
// create a promise instance
var socket = $q.defer();
// listen for the authenticated event emitted on the rootScope of
// the Angular app. Once the event is fired, create the socket and resolve
// the promise.
$rootScope.$on('authenticated', function() {
// resolve in another digest cycle
$timeout(function() {
var token = window.localStorage["socket_token"];
var token_query = 'token=' + token;
var newSocket = (function() {
return socketFactory({
ioSocket: io.connect('http://example.com:3000', {
query: token_query
})
});
})();
socket.resolve(newSocket);
});
});
return socket.promise
});
解决方案
You can simply add the call to forward()
before resolving the promise with the created socket:
newSocket = (function() { /* ... */ })()
newSocket.forward("event");
socket.resolve(newSocket);
