angularjs - 如何以 Angular 将依赖项注入(inject)到 module.config(configFn) 中

Question

在 Angular 中，我们可以将 $routeProvider 注入(inject)到 config 函数

module.config(function ($routeProvider) {


});

我想将我的服务注入(inject)其中

module.config(function ($routeProvider, myService) {


});

我确信该服务已正确定义，但它会抛出异常，指出未知的 myService，当我注入(inject)时发生事件

module.config(function ($routeProvider, $http) {


});

它仍然显示未知$http。

你知道为什么吗？

来自Modules页面，“模块加载和依赖项”部分:

Configuration blocks - get executed during the provider registrations and configuration phase. Only providers and constants can be injected into configuration blocks. This is to prevent accidental instantiation of services before they have been fully configured.

Run blocks - get executed after the injector is created and are used to kickstart the application. Only instances and constants can be injected into run blocks. This is to prevent further system configuration during application run time.

所以你不能将自己的服务或内置服务(如 $http)注入(inject)到 config() 中。使用run()相反。
