如何使用Angularjs将依赖项注入提供程序中? [英] How to inject dependencies into a provider using Angularjs?

问题描述

是否可以通过提供者方法进行DI?

Is it possible to do DI in a provider method?

在此示例中

angular.module('greet',[])
.provider('greeter',function() {

  this.$get=function() {

  };
})
.service('greeterService',function($http){
  console.log($http);
})
;

将$http注入服务似乎是正确的实现，但是在提供者方法中不起作用，并且会引发错误:

Injecting $http into service appears to be the correct implementation, but it doesn't work in a provider method and it throws an error:

未知提供者:$ http

Unknown provider: $http

provider方法是否可以与DI一起使用以注入服务?

Does the provider method work with DI to inject services?

推荐答案

您当然可以将$http注入提供程序.只要确保它出现在$get中，而不是函数构造函数中即可.如下:

You can certainly inject $http to provider. Just make sure it appears in $get, not the function constructor. As follows:

angular.module('greet',[]).provider('greeter',function() {
  this.$get = function($http) {

  };
});
