Asp.net mvc 使用混合MVC的AppBuilder.Map块中的Owin Web API设置Autofac

我想将我的Web API代码移动到.Map（“/API”inner=>）块中，这样我就可以将以下配置设置为不影响我的应用程序的MVC部分

下面是我试图做的，但由于web api不再解析autofac依赖项而失败

public void Configuration(IAppBuilder app)
{
    var builder = new ContainerBuilder();
    BuildContainer(builder);
    this._container = builder.Build();
    // Middlewares
    app.UseAutofacMiddleware(this._container); //should be the first middleware added to IAppBuilder
    app.UseAutofacMvc(); 
    //MVC
    DependencyResolver.SetResolver(new AutofacDependencyResolver(this._container)); 
    this.ConfigureAuth(app, _container.Resolve());

    app.Map(
        "/api",
        inner =>
            {
            var config = new HttpConfiguration();
            config.DependencyResolver = new AutofacWebApiDependencyResolver(this._container);
            WebApiConfig.Register(config);
            //inner.UseAutofacMiddleware(this._container); //should be the first middleware added to IAppBuilder
            inner.UseAutofacWebApi(config); //Web.API enable lifetime scope created during the OWIN request to extend into WebAPI.
            inner.UseWebApi(config);
        });
}

另外，如果我做了任何看起来有问题的事情，请告诉我。

我的问题是WebApiConfig仍在中注册

受保护的无效应用程序\u Start（）
{
GlobalConfiguration.Configure（WebApiConfig.Register）；
}

移除这个，autofac将地图下的一切都连接起来。奇怪的是，在没有地图的情况下注册可以让一切正常工作（也许还有其他我不知道的副作用）

我使用的最终配置：

公共无效配置（IAppBuilder应用程序）
{
var builder=new ContainerBuilder（）；
建筑容器（建筑商）；
这个._container=builder.Build（）；
//OWIN中间件
app.UseAutofacMiddleware（this._容器）；//应该是添加到IAppBuilder的第一个中间件
app.UseAutofacMvc（）；//Autofac MVC集成--
//MVC
DependencyResolver.SetResolver（新的AutofacDependencyResolver（此._容器））；//TODO:OWIN仍然需要吗？
//app.UseCors（Microsoft.Owin.Cors.CorsOptions.AllowAll）；
this.ConfigureAuth（app，_container.Resolve（））；
//WEB API配置-使WEB API URL使用配置，避免ASP.NET MVC继承HttpConfig。
应用程序地图(
“/api”，
内部=>
{
var config=新的HttpConfiguration（）；
config.DependencyResolver=新的AutoFacWebAPIDpendencyResolver（此.\u容器）；
WebApiConfig.Register（配置）；
inner.UseAutofacWebApi（config）；//Web.API允许在OWIN请求期间创建的生存期范围扩展到WebAPI中。
inner.UseWebApi（config）；
});
}

我认为我的问题归结为仍然在应用程序中配置\u启动GlobalConfiguration.Configure（WebApiConfig.Register）；

public void Configuration(IAppBuilder app)
{
    var config = new HttpConfiguration();
    var builder = new ContainerBuilder();
    BuildContainer(builder);
    this._container = builder.Build();
    // Middlewares
    app.UseAutofacMiddleware(this._container); //should be the first middleware added to IAppBuilder
    app.UseAutofacMvc();     
    // WebApi config
    config.DependencyResolver = new AutofacWebApiDependencyResolver(this._container);

    //MVC
    DependencyResolver.SetResolver(new AutofacDependencyResolver(this._container)); 
    this.ConfigureAuth(app, _container.Resolve());
    WebApiConfig.Register(config);
    app.UseAutofacWebApi(config); 
    app.UseWebApi(config);
}

public void Configuration(IAppBuilder app)
{
    var builder = new ContainerBuilder();
    BuildContainer(builder);
    this._container = builder.Build();
    // Middlewares
    app.UseAutofacMiddleware(this._container); //should be the first middleware added to IAppBuilder
    app.UseAutofacMvc(); 
    //MVC
    DependencyResolver.SetResolver(new AutofacDependencyResolver(this._container)); 
    this.ConfigureAuth(app, _container.Resolve());

    app.Map(
        "/api",
        inner =>
            {
            var config = new HttpConfiguration();
            config.DependencyResolver = new AutofacWebApiDependencyResolver(this._container);
            WebApiConfig.Register(config);
            //inner.UseAutofacMiddleware(this._container); //should be the first middleware added to IAppBuilder
            inner.UseAutofacWebApi(config); //Web.API enable lifetime scope created during the OWIN request to extend into WebAPI.
            inner.UseWebApi(config);
        });
}

protected void Application_Start() 
{
  GlobalConfiguration.Configure(WebApiConfig.Register);
}

public void Configuration(IAppBuilder app)
{
        var builder = new ContainerBuilder();
        BuildContainer(builder);
        this._container = builder.Build();
        // OWIN Middlewares
        app.UseAutofacMiddleware(this._container); //should be the first middleware added to IAppBuilder
        app.UseAutofacMvc(); // Autofac MVC Integration -- http://alexmg.com/owin-support-for-the-web-api-2-and-mvc-5-integrations-in-autofac/
        //MVC
        DependencyResolver.SetResolver(new AutofacDependencyResolver(this._container)); //TODO: Still needed with OWIN?
        //app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
        this.ConfigureAuth(app, _container.Resolve());
        //WEB API config - Make Web Api urls use the config, avoiding ASP.NET MVC from inheriting the HttpConfig.
        app.Map(
            "/api",
            inner =>
                {
                var config = new HttpConfiguration();
                config.DependencyResolver = new AutofacWebApiDependencyResolver(this._container);
                WebApiConfig.Register(config);
                inner.UseAutofacWebApi(config); //Web.API enable lifetime scope created during the OWIN request to extend into WebAPI.
                inner.UseWebApi(config);
            });
