如何将websocket变量传递给控制器，以便通过相同的websocket连接发回数据？

  app.factory('MyData', function($websocket, $q){
      // Open a WebSocket connection
      var dataStream = $websocket('ws://address');

      var collection = [];


       dataStream.onMessage(function(message) {
       var data = collection.push(JSON.parse(message.data)); 
       var data = (JSON.stringify(collection));
       var data = Object(collection);

       // Check for requests to Delete posted Questions.

        for (var i = 0; i < data.length; i++) {
            var uuid1 = collection[i].uuid;
            // console.log(uuid1);

              for (var j = 0; j < data.length; j++) {
                  var uuid2 = collection[j].uuid;
                  // console.log(uuid2);

                   if (i !=j){

                        if (uuid1 == uuid2){
                          console.log("Delete Question Request for uuid: " + uuid1);
                          collection.splice(i);
                          collection.splice(j);
                      }
                        else console.log("No Questions to Delete");
                    }
              }
        }

      });

       //Function that returns data from websocket and parses into JSON Array

      var methods = {
        collection: collection, 
        get: function() {
          dataStream.send({ action: 'get' });
        }

      };


      return methods;

    });

我的控制器有函数joinChatRoom（），我试图通过相同的开放websocket连接发回数据。：

    app.controller('WaitingRoom', function ($scope, $websocket, MyData) {

      $scope.MyData = MyData;
      console.log(MyData);



      $scope.joinChatRoom = function(uuid){

          var code = "code";
          var uuidTitle = "uuid";
          var chatRequest  = {};
          chatRequest[code] = 100;
          chatRequest[uuidTitle] = uuid;

          var sendChatRequest = JSON.stringify(chatRequest);

          // send request to join chat room.
          dataStream.send(sendChatRequest);

      };


});

Answer 1

我猜你在工厂里有某种获取数据的getter函数...... 您所要做的就是将WebSocket服务注入控制器的范围，您应该能够调用getter函数，其余部分将完成。 .controller（＆＃39;）

您需要在致电：

时从控制器向您的工厂发送回调
