如何在angular指令中使用已注册的控制器？

I have a controller registered like this:

我有一个像这样注册的控制器：

myModule.controller('MyController', function ($scope, ...some dependencies...)
{
    ....

Using ng-controller="MyController" in the HTML it all works fine, but now I want to use this controller as my directive's controller. Some thing like this:

在HTML中使用ng-controller =“MyController”它一切正常，但现在我想使用这个控制器作为我的指令控制器。有点像这样：

otherModule.directive('myDirective', function() {
    return {
        restrict: 'A',
        replace: true,
        controller: ??????????,
        scope: {
            foo: '=',
            blah: '=',
        },
        template: '....'
    }
});

I tired just putting MyController but it errors out saying "MyController is not defined". I'm sure if I just put MyController in the global namespace, it would work fine, but I don't want anything in the global namespace. If it makes a difference, myModule is defined as a dependency for otherModule. How can I get a reference to this controller for my directive to use?

我只是把MyController放了，但是错误地说“MyController没有被定义”。我敢肯定，如果我只是将MyController放在全局命名空间中，它会正常工作，但我不想要全局命名空间中的任何内容。如果它有所不同，myModule被定义为otherModule的依赖项。我怎样才能获得对该控制器的引用以供我的指令使用？

As suggested, I tried $controller('MyController'), but now I am getting the following error:

按照建议，我尝试了$ controller（'MyController'），但现在我收到以下错误：

Error: Unknown provider: $scopeProvider <- $scope <- myDirectiveDirective

I'm not sure what to make of this error. Is there more needed to make this work?

我不知道该怎么做这个错误。还有更多需要使这项工作？

2 个解决方案

It appears that you can just use:

看来你可以使用：

controller: 'MyController'

IF the controller is in the same module as the directive or a higher level module composed of the module with the directive in it.

如果控制器与指令位于同一模块中，或者由带有指令的模块组成的更高级别模块。

When I tried it with two different modules composed into an app module (one for the controller and one for the directive), that did not work.

当我尝试将两个不同的模块组成一个app模块（一个用于控制器，一个用于指令）时，这不起作用。

The answer you've already accepted works, and in almost all cases should be chosen...

您已经接受的答案有效，几乎在所有情况下都应该选择......

For sake of completeness: Here is how you can use a controller from another module

为了完整起见：以下是如何使用其他模块的控制器

(PS: Don't do this. lol :P)

（PS：不要这样做。哈哈：P）

var app = angular.module('myApp', ['myDirectives']);

app.controller('AppCtrl1', function($scope) {
    $scope.foo = 'bar';
});


var directives = angular.module('myDirectives', []);

directives.directive('test', function($controller) {
   return {
       template: '<h1>{{foo}}</h1>',
       link: function(scope, elem, attrs) {
          var controller = $controller('AppCtrl1', { $scope: scope });

          console.log($scope.foo); //bar
       }
   };
});
