如何在使用ng-include加载不同视图时捕获internet断开连接错误

<div ng-include="'views/view1.html'"></div>

app.controller('MainController', function($scope, $http) {
  $scope.loadView = function(viewUrl) {
    $http.get(viewUrl)
      .then(function(response) {
        // 视图加载成功
        $scope.viewContent = response.data;
      })
      .catch(function(error) {
        // 捕获Internet断开连接错误
        console.log("Internet连接错误：" + error);
      });
  };
});

<button ng-click="loadView('views/view1.html')">加载视图1</button>
<button ng-click="loadView('views/view2.html')">加载视图2</button>
