AngularJS的控制器调用HTTP多次 [英] AngularJS calls HTTP multiple times in controller
问题描述
我发展与角一个页面，并在我的控制器的init（）方法。在code是如下：
I am developing a page with Angular, and have an init() method in my controller. The code is as follows:
var filtersController = ['$scope', '$http', function ($scope, $http) {
$scope.init = function () {
$http({
method: 'GET',
url: '/json-tags-test',
cache: true
}).success(function (data, status, headers, config) {
// this callback will be called asynchronously
// when the response is available
}).error(function (data, status, headers, config) {
// called asynchronously if an error occurs
// or server returns response with an error status.
});
};
}];
这仅仅是一个简单的JSON文件的调用。
It is just a call to a simple JSON file.
我的HTML如下：
<div class="container main-frame" ng-app="projectsApp" ng-controller="filtersController" ng-init="init()">
</div>
由于某些原因，这让通话变得我每次加载页面调用时间的两倍。这是标准的行为？
For some reason, this get call gets call twice every time I load the page. Is this standard behaviour?
非常感谢，

推荐答案
这问题也可以由具有NG-应用与路由控制器并在页面中的NG-控制器参考引起的。例如，如果你的应用程序是这样的：
This problem may also be caused by having an ng-app with routing to your controller and an ng-controller reference in your page. For example, if your app looks like:
<html lang="en" ng-app="myApp">
<head>...</head>
<body>
<div ng-controller="myController">
...
</div>
</body>
</html>
定义的Javascript应用程序：
Javascript defining the app:
angular.module('myApp',[]) {
$routeProvider.when('/path', {templateUrl: '...', controller: myController);
在上面的例子中，与定义的路由myController的，控制器将被实例化两次，你会看到所描述的两个电话。
In the case above, with the defined routing to myController, the controller will be instantiated twice and you'll see two calls as described.
更新
以上code描述什么是问题，但什么是正确的解决方案，缺少所以我更新的答案，每@Intrepid评论。
Above code describe what is problem but what is proper solution is missing so I updated answer as per @Intrepid comment.
需要删除 NG-控制器=myController的从如果你已经路线定义你的HTML模板。
Need to remove ng-controller="myController" from your html template if you already defined in route.
