Azure Functions中的DI [英] DI in Azure Functions

问题描述

我在ASP.NET Web API应用程序中使用了一些类库，这些类库可以处理所有后端内容，例如对多个数据库(例如Azure SQL数据库，Cosmos DB等)进行CRUD操作.

我不想重新发明轮子，也不能在我在Visual Studio 2017中创建的新Azure函数中使用它们.我的所有存储库方法都使用一个接口.那么，如何在新的Azure函数中实现依赖项注入?

我没有看到对DI的任何支持，但是有点困惑.看来Azure函数是基于与WebJobs相同的SDK的，并且我认为去年Microsoft已开始在WebJobs中支持DI-我可以肯定，因为我使用Ninject实施了它.

是否可以解决此问题，以便可以在新的Azure Functions项目中使用现有的库?

解决方案

除了服务定位器(anti)模式，我还看到了这两种技术.我也向Azure Functions团队征求了他们的意见.

I have some class libraries that I use in my ASP.NET Web API app that handle all my backend stuff e.g. CRUD operations to multiple databases like Azure SQL Database, Cosmos DB, etc.

I don't want to re-invent the wheel and able to use them in a new Azure Functions that I'm creating in Visual Studio 2017. All my repository methods use an interface. So, how will I implement dependency injection in my new Azure function?

I'm not seeing any support for DI but I'm a bit confused. It appears Azure Functions are based on the same SDK as WebJobs and I think last year Microsoft had started supporting DI in WebJobs - I know for sure because I implemented it using Ninject.

Is there way around this so that I can use my existing libraries in my new Azure Functions project?

解决方案

I see these two techniques in addition to the service locator (anti)pattern. I asked the Azure Functions team for their comments as well.
