angularjs第二次http调用不成功

Question

我有一个在控制器加载时调用的函数（对应于tab-plan.html的PlanCtrl，其中填充了手风琴列表，见下文）：

$scope.initialize = function() {

  if ($cookies.token) {
    $http.defaults.headers.common.Authorization = 'Token ' + $cookies.token;
  }

  var url = "https://127.0.0.1:8000/api/exercises/get_exercise/";
  var memory_url = "https://127.0.0.1:8000/api2/games/get_game/";

  $http({
    url: memory_url,
    method: 'GET',
    headers: {
      'X-CSRFToken': $cookies['csrftoken'],
      'Content-Type': 'application/json; charset=utf-8'
    }
  })

  .success(function(response) {
    alert("suc 1")
    $scope.initial_data_memory = response;
    console.log($scope.initial_data_memory);

    angular.forEach($scope.initial_data_memory, function(item) {

      $scope.game_type = item.game_type;

      //check the exercise date  
      $scope.current_date_memory = item.current_date;


      $scope.days = Plan.all();
      //Iterate over the list
      angular.forEach($scope.days, function(value1, key) {

        //iterate over the list of exercises
        angular.forEach(value1.exercises, function(value2, key) {

          // Check if the fetched exercise id is same as current exercise from the frontend list and check if the fetched date is today 
          if (value2.id == $scope.game_type && $scope.today === $scope.current_date_memory) {
            // If the fetched date is todat i.e. exercise was rated today: set the flag for watchedTodat to true 
            value2.watchedToday = true;

          }

        });

      });

    });
  });

  $http({
    url: url,
    method: 'GET',
    headers: {
      'X-CSRFToken': $cookies['csrftoken'],
      'Content-Type': 'application/json; charset=utf-8'
    }
  })

  .success(function(response) {
    alert("suc 2")
    $scope.initial_data = response;
    console.log($scope.initial_data);

    angular.forEach($scope.initial_data, function(item) {

      $scope.exercise_type = item.exercise_type;

      //check the exercise date  
      $scope.current_date = item.current_date;


      $scope.days = Plan.all();
      //Iterate over the list
      angular.forEach($scope.days, function(value1, key) {

        //iterate over the list of exercises
        angular.forEach(value1.exercises, function(value2, key) {
          // Check if the fetched exercise id is same as current exercise from the frontend list and check if the fetched date is today 
          if (value2.id == $scope.exercise_type && $scope.today === $scope.current_date) {
            // If the fetched date is today i.e. exercise was rated today: set the flag for watchedTodat to true 
            value2.watchedToday = true;

          }

        });

      });

    });
  });

};

它有两个http调用（顺序无所谓），当控制器第一次加载时只执行第一次调用，当第二次加载时，第二次http调用执行/成功。

为什么会这样？

更新 我在两个成功部分都设置了警报：两个都进行了HTTP调用，但最后一个语句value2.watchedToday = true;设置了一个布尔值以启用复选标记，仅设置第二个http调用。见图像波纹管（理想情况下应该有复选标记Best Stretch和Buttterfly反向）：

HTML：

<ion-list>
  <div ng-repeat="day in days"><br>
    <div class="item item-icon-left"  ng-click="toggleGroup(day)" ng-class="{active: isGroupShown(day)}">
      <i class="icon icon-accessory" ng-class="isGroupShown(day) ? 'ion-minus' : 'ion-plus'"></i>
      &nbsp;
      {{day.name}}
    </div>
    <a class="item item-icon-left item-accordion" ng-show="isGroupShown(day)" ng-repeat="exercise in day.exercises" type="item-text-wrap"
       href="#/tab/plan/{{exercise.id}}">
      {{exercise.name}}

      <!-- Trial LED -->

        <span style="float:right;"><i ng-show="{{exercise.watchedToday}}==true" class="ion-checkmark-round"></i></span>

    </a>
  </div>
</ion-list>

    },
    cache: false
  })

  .state('tab.simon', {
    url: '/plan/8', 
    resolve: {
      authenticated: ['djangoAuth', function(djangoAuth){

      }],
    },
    views: {

        templateUrl: '/templates/simon.html',
        controller: 'simonCtrl',
        data: {
          css: '/css/simon.css'

      }
    },
    cache: false
  })
...
.state('tab.exercise', {
    url: '/plan/:exerciseId', 
    resolve: {
      authenticated: ['djangoAuth', function(djangoAuth){
        return djangoAuth.authenticationStatus();
      }],
    },

        templateUrl: '/templates/video.html',
        controller: 'videoCtrl'
      }
    },
    cache: false
  })
