用于 autofac 的 Api 异常过滤器

Question

我已使用IAutofacExceptionFilter 配置 webapi 以获取异常详细信息。在 autofac.config 中注册了所有的东西

HttpConfiguration config = ServiceConfig.Initialize(new ConfigBuilder(options, (configuration, builder) =>
{  
       builder.RegisterType<ErrorLoggingExceptionFilter>()
       .AsWebApiExceptionFilterFor<BaseController>()
       .InstancePerApiRequest();

       builder.RegisterWebApiFilterProvider(GlobalConfiguration.Configuration);
       //builder.RegisterType<ErrorLoggingExceptionFilter>()
       //.AsWebApiExceptionFilterFor<BaseController>().SingleInstance();

       builder.OverrideWebApiActionFilterFor<BaseController>();
       builder.RegisterSource(
       new AnyConcreteTypeNotAlreadyRegisteredSource(t => 
         !(t.IsGenericType && t.GetGenericTypeDefinition() == typeof(Meta<>))
    ));
}
 var serviceResolver = (AutofacWebApiDependencyResolver)config.DependencyResolver;

但它给了我这样的错误

AutofacWebApiDependencyResolver 必须配置为 Web API 的依赖解析器，AutofacControllerConfigurationAttribute 才能从容器中解析控制器类型的服务。

您应该这样做以使 AutofacWebApiDependencyResolver 成为您的默认 Web API 依赖解析器：

// Set the dependency resolver to be Autofac.
var builder = new ContainerBuilder();
var container = builder.Build();
config.DependencyResolver = new AutofacWebApiDependencyResolver(container);

请参阅Autofac documentation 了解更多信息。
