Youtube API v3 console.logging方式太多了

Question

我有一些代码应该channelinfo by name，然后是playlistId by channelinfo，然后是videoes by playlistId，最后是videodetails by videos。

在大约200个视频中，它接听相同的YouTube API 500次。

我的代码如下。

服务：

appApi.factory('ServiceAPI', ['$http', function($http) {
  var factory = {};

  factory.channelDetails = function(channelname, success, error){
    var promise = $http.get('https://www.googleapis.com/youtube/v3/channels?part=contentDetails&forUsername='+channelname+'&key=AIzaSyDQv-WpATIWLinCB3H_sH4W1sKx7plyvRA')
    if(success){
      promise.success(success);
    }
    if(error){
      promise.error(error);
    };
  }
  return factory;
}]);

appApi.factory('ServiceCHLnames', ['$http', function($http) {
  var factory = {};

  factory.channelnames = function(success, error){
    var promise = $http.get('http://localhost:8080/api/resources/channelNames')
    if(success){
      promise.success(success);
    }
    if(error){
      promise.error(error);
    };
  }
  return factory;
}]);

appApi.factory('ServiceVideos', ['$http', function($http) {
  var factory = {};

  factory.videos = function(playlistId, success, error){
    var promise = $http.get('https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&maxResults=50&playlistId=' + playlistId + '&key=AIzaSyDQv-WpATIWLinCB3H_sH4W1sKx7plyvRA')
    if(success){
      promise.success(success);
    }
    if(error){
      promise.error(error);
    };
  }
  return factory;
}]);

appApi.factory('ServiceVideoDtls', ['$http', function($http) {
  var factory = {};

  factory.videodetails = function(videoid, success, error){
    var promise = $http.get('https://www.googleapis.com/youtube/v3/videos?part=statistics&id=' + videoid + '&key=AIzaSyDQv-WpATIWLinCB3H_sH4W1sKx7plyvRA')
    if(success){
      promise.success(success);
      console.log("GOT ONE VIDEO DETAIL")
    }
    if(error){
      promise.error(error);
    };
  }
  return factory;
}]);

控制器：

var appApi = angular.module('YoutubeAPI', ['ngRoute'])

appApi.controller('youtubeCTRL', ['$scope','$http','$q','ServiceAPI','ServiceCHLnames','ServiceVideos','ServiceVideoDtls', function ($scope, $http, $q, ServiceAPI,ServiceCHLnames,ServiceVideos,ServiceVideoDtls) {
    $scope.channel = [];
    $scope.video = [];
    var playlistId = [];


    var pagetokenarr = [];

    //GET Id on channelname
    $scope.saveNewchlName = function () {

        var channelname = $scope.newchlName;

            ServiceAPI.channelDetails(channelname, function(data){

                $scope.newchannelNames = {
                    channelName: $scope.newchlName,

                    playlistId: data.items[0].contentDetails.relatedPlaylists.uploads
                };
                console.log($scope.newchannelNames)

                    $scope.error = null;
                }).error(function (data, status) {

                                });

                    })

我不知道造成这个问题的原因是什么，或者是否正常。

当我用邮递员检查http://localhost:8080/api/resources/videos/时，有200个视频应该调用（并且已经完成）。 但它仍然不断打印成功＆＃34; SUCCESS＆＃34; console.log太多了。

所以视频数组正在进行一些异步调用，因此我的代码在视频被正确推送到数组之前发布了一些数据。

我刚刚删除了数组，但它确实有效。
