问题描述
我正在尝试通过遵循工厂方法文档中的示例来构建自己的服务。我想我做错了，因为我继续遇到未知的提供程序错误
I'm trying to build my own service by following the example in the documentation for the factory methodology. I think I've done something wrong however because I continue to get the unknown provider error

请向我指出正确的方向。
Please point me to the right direction.
推荐答案
在依赖项数组中存在不匹配项，请确保在使用它们之前已正确注入了所有依赖项。
You have mismatch in the dependency array, make sure all the dependency has injected correctly before using them.
MainController.$inject = ['$scope','github','$interval','$log','$achorScroll','$location'];
另外，您需要将; 替换为：在您的 github 工厂
Additionaly you need to replace ; by : in your github factory
return{
getUser : getUser,
getRepos : getRepos //<--correction in this line
};
