问题描述
我有一个 UI路由器 StateProvider ，需要控制器和放大器之间挑;基于外部数据的看法，所以我用 TemplateProvider 和 ControllerProvider 。
I have a ui-router StateProvider and need to pick between controllers & views based on external data, so I used TemplateProvider and ControllerProvider.
如果我只用了 TemplateProvider 这一切工作正常，但是当我添加 ControllerProvider 我得到这个错误
If I only had the TemplateProvider it all works fine, but when I add the ControllerProvider I get this error:
Error: [ng:areq] Argument 'fn' is not a function, got Object

看起来有些未定义 服务名可能（它说了对象，但它看起来像它的未定义但我不是在调试巨大的 AngularJs ）
Looks like some undefined serviceName possibly (it says got object, but it looks like it's undefined but I'm not great at debugging AngularJs)
下面是我的code：
.state('abstractParent.childState', {
url: '/childState',
controllerProvider: ['myService', function (myService) {
return myService
.isSpecificMember()
.then(function (result) { //this returns a promise of a bool.
if (result.data) {
return 'SpecificController';
} else {
return 'GeneralController';
}
})
}],
templateProvider: ['myService', '$templateFactory',
function (myService, $templateFactory) {
return myService.isSpecificMember().then(function(result) {
if(result.data)
{
return $templateFactory.fromUrl('SpecificView');
} else {
return $templateFactory.fromUrl('GenericView');
}
})
}],
resolve: {
thing: ['thingService', function (thingService) {
//this is only used in one of the controllers.
return thingService.getThing();
}]
}})
修改
根据拉迪姆Köhlers答案更改
Changes based on Radim Köhlers answer
.state('abstractParent.childState', {
url: '/childState',
resolve: {
controllerName: ['myService', function (myService) {
return myService.isSpecificMember().then(function (result) { //this returns a promise of a bool.
if (result.data) {
return 'SpecificController';
} else {
return 'GeneralController';
}
})
}],
thing: ['thingService', function (thingService) { //this is only used in one of the controllers.
return thingService.getThing();
}]
},
controllerProvider: ['controllerName', function (controllerName) {
return controllerName;
}],
templateProvider: ['myService', '$templateFactory', function (myService, $templateFactory) {
return myService.isSpecificMember().then(function(result) {
if(result.data)
{
return $templateFactory.fromUrl('SpecificView');
} else {
return $templateFactory.fromUrl('GenericView');
}
})
}]
})
新的错误：

SOLUTION
这至少需要版本 0.2.14 的角-UI-router.js
推荐答案
的一点是，该 controllerProvider 只是必须返回的目标重新presenting的控制器或字符串的（它的名字）的
The point is, that controllerProvider simply must return object representing the controller or string (its name)
的.$stateProvider
http://angular-ui.github.io/ui-router/site/#/api/ui.router.state.$stateProvider
stateConfig.controllerProvider （可选）的功能
这是返回实际的控制器或注射提供商功能的字符串
Injectable provider function that returns the actual controller or string.
所以，我们不能回到诺言...
So, we cannot return promise...
不过，有一个解决方案：
But there is a solution:
有
我们可以使用内置功能的解析 - 做异步的东西，使 controllerProvider 英雄 - 通过消耗：
We can use built-in feature resolve - to do the async stuff, and make controllerProvider a hero - by consuming it:
resolve: {
controllerName: ['$stateParams', '$timeout','$q',
function ($stateParams, $timeout, $q)
{
var deferred = $q.defer();
$timeout(function(){
deferred.resolve('MyLazyRevealedCtrl');
},250);
return deferred.promise;
}],
},
controllerProvider:['controllerName', function (controllerName)
{
return controllerName;
}],
我们可以看到被简化，只需定时例子（异步扮演角色的 。然后（） ）。它等待了一段时间，并返回解析控制器的名称。
What we can see is simplified example with just a timer (playing role of async .then()). It waits a while and returns resolved controller name.
在 controllerProvider 和的（一次全部解决）的只是需要这一结果，并返回一个字符串。
The controllerProvider then (once all is resolved) just takes that result, and returns it as a string.
