Autofac + WCF REST 4.0 [英] Autofac + WCF REST 4.0

问题描述

我建立一个WCF 4.0 REST服务，并希望使用Autofac作为DI容器。很显然，我希望能够调用的服务类（服务合同执行），它接受了一堆接口一起工作的一个参数的构造函数。这些接口要在Autofac容器中注册，我想他们解决，创造我服务类的一个实例时（而不是调用没有参数的构造函数，这是默认值）使用。

I am building a WCF 4.0 REST service and want to use Autofac as DI container. Apparently, I want to be able to call a parameterized constructor of the service class (service contract implementation), which accepts a bunch of interfaces to work with. Those interfaces are to be registered within Autofac container and I want them resolved and used when creating an instance of my service class (instead of calling not parameterized constructor, which is default).

有类似的问题，MVC控制器，这是由Autofac MVC集成封装解决。有没有什么现成的使用WCF REST 4.0？如果没有，什么是解决我的问题的最好方法是什么？例如，有什么样的MVC的DependencyResolver，我可以设置为使用Autofac？

There is similar problem with MVC controllers, which is solved by Autofac MVC Integration package. Is there anything ready-to-use for WCF REST 4.0? If no, what is the best way to solve my problem? E.g., is there anything like MVC's DependencyResolver which I can set up to use Autofac?

请注意，既然4.0，他们改变了一些概念WCF休息。例如，现在有没有 .SVC 文件，路由就足以调用所需的方法。我是很新的WCF REST 4.0，所以我想问问社区的建议，在实施一些巨大的自定义机制消磨时间了。唉，在网上快速搜索并没有给我提供一个可以接受的解决方案。

Note, that since 4.0 they changed some concepts in WCF REST. E.g., now there is no .svc file, routing is enough to call required method. I am quite new to WCF REST 4.0, so I wanted to ask community for suggestions before spending days on implementing some huge custom mechanism. Alas, quick search over internet did not provide me with an acceptable solution.

推荐答案

在您的全球应用程序的启动：

In your global application startup:

//Build a container with your service registered.
var builder = new ContainerBuilder();
builder.RegisterType<YourService>();
var container = builder.Build();

//Set AutofacHostFactory.Container with this built container.
AutofacHostFactory.Container = container;

//Use AutofacWebServiceHostFactory instead of WebServiceHostFactory
var factory = new AutofacWebServiceHostFactory();

//Add your routes
RouteTable.Routes.Add(new ServiceRoute("YourServiceUrl", factory, typeof(YourService)));

这就是全部。

That's all.
