PubNub AngularJS 未定义函数 ngSubscribe

Question

我试图按照 pubnub 网站

上的指南将 PubNub 与 AngularJS 一起使用

我的代码在app.js:

var myapp = angular.module('myapp', ["pubnub.angular.service"])
    .controller('MessagesController', ['$scope', '$http', '$log', '$rootScope', function($scope, $http, $log, $rootScope) {
    ....

首先我做 $scope.initPubNub();然后调用 $scope.subscribe();

$scope.initPubNub = function() {
    if (!$rootScope.initialized) {
        pubNubDemo = PubNub.init({
              publish_key: 'some token here',
              subscribe_key: 'yet another token',
              uuid: $scope.senderId
        });
    };
    $rootScope.initialized = true;
    console.log("PUBNUB inited");
};

最后一个订阅方法：

$scope.subscribe = function(theChannel) {
    console.log("1111aaaa");

    theChannel = typeof theChannel !== 'undefined' ? theChannel : "/chats/3";

    console.log(theChannel);

    console.log("????111");
    cpubNubDemo.ngSubscribe({ channel: theChannel })
    console.log("????222");


  pubNubDemo.subscribe({ channel: theChannel, callback: function() { console.log(arguments); }});

  console.log("zzzzz");

  $rootScope.$on(pubNubDemo.ngMsgEv(theChannel), function(event, payload) {
    // payload contains message, channel, env...
    console.log('got a message event:', payload);
  })

  $rootScope.$on(pubNubDemo.ngPrsEv(theChannel), function(event, payload) {
    // payload contains message, channel, env...
    console.log('got a presence event:', payload);
  })
};

我在浏览器中得到了跟踪：

它告诉我们 ngSubscribe 不是一个函数。我做错了什么？我用凉亭安装了 "pubnub-angular" 组件。在 bower_components/pubnub-angular/lib/pubnub-angular.js 我看到：

// Generated by CoffeeScript 1.6.3
(function() {
  'use strict';
  angular.module('pubnub.angular.service', []).factory('PubNub', [
    '$rootScope', function($rootScope) {
      var c, k, _i, _len, _ref;
      c = {
        'VERSION': '1.1.0',
        '_instance': null,
        '_channels': [],
        '_presence': {},
        'jsapi': {}
      }; 
      .... 
      c.ngSubscribe = function(args) {
        var _base, _name;
        if (c['_channels'].indexOf(args.channel) < 0) {
          c['_channels'].push(args.channel);
        }
        (_base = c['_presence'])[_name = args.channel] || (_base[_name] = []);
        args = c._ngInstallHandlers(args);
        return c.jsapi.subscribe(args);
      };
      ....

我做错了什么？

Answer 1

应该是这样的：

.controller('MessagesController', ['$scope', '$http', '$log', '$rootScope','PubNub' , function($scope, $http, $log, $rootScope, PubNub) {

Answer 2

也许值得补充和强调的是，如果最后注入 PubNub 依赖项.

，我只能让它工作

PubNub AngularJS 未定义函数 ngSubscribe

PubNub AngularJS undefined function ngSubscribe

javascript

ruby-on-rails

angularjs
