自托管web api和autofac集成。 [英] Self hosted web api and autofac integration.

问题描述

Hi


我正在托管一个web api，它在Windows服务中公开了一些REST服务。由于这是一个Windows服务，我使用HttpSelfHostServer类来托管api。有没有人对如何将autofac IoC与自托管的web api集成有任何见解。我知道在使用IIS来托管api时有一个整合nuget包但我找不到任何自托管方案。任何建议将不胜感激。

解决方案

我找到了解决问题的方法。 Actualy所需的步骤几乎与使用IIS中托管的web api设置autofac时相同。因此，要使用自托管的web api设置autofac，请按照以下步骤操作：



- 下载Autofac.WebApi nuget包

- 像往常一样设置autofac构建器

- 唯一的区别是你必须将autofac指定为web api的依赖解析器。在自托管方案中无法访问GlobalConfiguration，因此您只需在HttpSelfHostConfiguration实例上使用DependencyResolver属性：

  var  builder =  new  ContainerBuilder（）; 
  //  像往常一样注册API控制器和其他类型 
 
  var  container = builder.Build（）; 
  var  resolver =  new  AutofacWebApiDependencyResolver（container）; 
  var  config =  new  HttpSelfHostConfiguration（ @   http：// localhost：9099）; 
 config.DependencyResolver = resolver; 
  var  server =  new  HttpSelfHostServer（config）; 

Hi
I am hosting an web api which exposes a few REST services in a windows service. Since this is a windows service I use the HttpSelfHostServer class to host the api. Does anybody has any exprience on how to integrate an autofac IoC with self hosted web api. I know there is an integraion nuget package when using IIS to host the api but I could not find anything for self-hosted scenarios. Any advice will be appreciated.

解决方案

I found the solution to my problem. Actualy the steps needed are almost the same as when setting the autofac with web api hosted in the IIS. So to set-up the autofac with the self-hosted web api follow the next steps:

- download the Autofac.WebApi nuget package
- set the the autofac builder as you normally would
- the only difference is whan you have to assign the autofac as a dependency resolver to the web api. GlobalConfiguration is not accessible in the self-hosted scenario so you just use the DependencyResolver property on the HttpSelfHostConfiguration instance:

var builder = new ContainerBuilder();
//Register the API controllers and other types as you normally would

var container = builder.Build();
var resolver = new AutofacWebApiDependencyResolver(container);
var config = new HttpSelfHostConfiguration(@"http://localhost:9099");
config.DependencyResolver = resolver;
var server = new HttpSelfHostServer(config);
