Question

我正在使用Angular 1.6 / MVC 4.6 / E.F 6.0在Web应用程序上工作。我还添加了UI-Grid。它运作良好。我尝试创建自定义过滤器，例如this part of documentation。我的目标是创建与＆＃34; Age＆＃34;相同的自定义过滤器。它在本地工作，但不是在我发布WebApp时。我有两个错误：

Possibly unhandled rejection: canceled
Error: [$injector:unpr] http://errors.angularjs.org/1.6.2/$injector/unpr?p0=nProvider%20%3C-%20n%20%3C-%20myCustomModalCtrl

我非常确定它与我为此自定义过滤器添加的控制器/指令有关。我已经引用了Angular JS help page，但我不知道如何纠正这个错误，以及为什么它只能在本地工作

不确定这是否有帮助，但您的问题可能与myCustomModalCtrl控制器的声明有关。与其他声明相比，此声明缺少注入服务的完整合格声明：

PrintersApp.controller('myCustomModalCtrl', function ($scope, $compile, $timeout) { [..] });

应该是：

PrintersApp.controller('myCustomModalCtrl', ['$scope', '$compile', 
'$timeout', function ($scope, $compile, $timeout) { [..] }]);

当您的代码缩小时，参数$scope将重命名为，例如a。这会导致您收到的错误，因为a中没有宣布名为$injector的服务。

为了避免这个问题，我们必须告诉$injector为我们在控制器中请求的每个参数注入正确的服务名称。
