我知道AngularJS会将一些代码运行两次，有时甚至更多，比如$watch events，不断检查模型状态等等。
然而我的代码:
function MyController($scope, User, local) {
var $scope.User = local.get(); // Get locally save user data
User.get({ id: $scope.User._id.$oid }, function(user) {
$scope.User = new User(user);
local.save($scope.User);
});
//...
执行两次，将2条记录插入到我的DB中。我显然还在学习，因为我已经用我的头撞它很多年了!

我刚刚讲过这个问题，但这个问题与公认的答案不同。我真的要把这些留给未来的自己，包括我为解决这个问题所采取的步骤。
Remove redundant controller declarations Check trailing slashes in routes Check for ng-ifs Check for any unnecessary wrapping ng-view calls (I accidentally had left in an ng-view that was wrapping my actual ng-view. This resulted in three calls to my controllers.) If you are on Rails, you should remove the turbolinks gem from your application.js file. I wasted a whole day to discover that. Found answer here. Initializing the app twice with ng-app and with bootstrap. Combating AngularJS executing controller twice When using $compile on whole element in 'link'-function of directive that also has its own controller defined and uses callbacks of this controller in template via ng-click etc. Found answer here.

我的问题真的很难找到。最后，当网页缺少图像时，问题就出现了。src缺少一个Url。这发生在MVC 5 Web控制器上。为了解决这个问题，当没有真实图像可用时，我添加了透明图像。
<img alt="" class="logo" src="">
我有同样的问题，在一个简单的应用程序(没有路由和一个简单的ng-controller引用)，我的控制器的构造函数运行了两次。最后，我发现我的问题是以下声明自动引导我的AngularJS应用程序在我的Razor视图
<html ng-app="mTest1">
我还使用angular手动引导它。引导。
angular.bootstrap(document, [this.app.name]);
所以去掉其中一个，对我有用。
特此补充，以供参考:
在同样运行在页面上的指令中引用控制器也可能导致双控制器代码执行。
e.g.
return {
restrict: 'A',
controller: 'myController',
link: function ($scope) { ....
当你也有ng-controller="myController"在你的HTML
当在Angular 1.3+中使用Angular -ui-router时，有一个关于在路由转换时渲染视图两次的问题。这也导致执行了两次控制器。提出的解决方案没有一个对我有效。
但是，将angular-ui-router从0.2.11更新到0.2.13，为我解决了这个问题。
