Question

我有一个工厂，使用angular-websocket连接后端，我需要将信息从我的控制器传递给它，以便它发送该信息，我想将其作为一个数组传递。工厂就是这样：

.factory('registerService', function($websocket) {
  var dataStream = $websocket('ws://localhost:3000'); //websocket
  dataStream.onOpen(function() {
    console.log('in');
    this.sendId = function(data) {
    console.log('data: '+data);
    };
  })
  dataStream.send(function(message) {
    //send info to backend
  });
})

和控制器一样：

.controller("registerController", function($scope,$stateParams,$ionicPopup,$state,registerService) {
  $scope.registerService = registerService;
  $scope.signUp = function() {
        registerBox = [];
        registerBox.push('Register')
        registerService.sendId(registerBox);
  };
})

但是我收到错误：registerService.sendId不是函数。问题是什么？

     .factory('registerService', function($websocket) {
          var dataStream = $websocket('ws://localhost:3000'),
              _this = this;

          dataStream.onOpen(function() {
            console.log('in');
            _this.sendId = function(data) {
               console.log('data: '+data);
            };
          })
          dataStream.send(function(message) {
            //send info to backend
          });

         return _this;
   });

将数组从控制器传递到出厂错误
