使用 Owin 和 Web API 和 SimpleInjector 找不到资源

Question

当我在 owin OAUth 旁边使用 Simpleinjector 进行基于令牌的登录时，Simpleinjector 无法解析我的控制器，并且出现“找不到资源”消息的 404 错误。

我使用 owin 管道处理我的请求，并使用 Owin Security 来生成和验证用户令牌。

Simpleinjector 作为 DI 和 ASP.NET 5

我在 stackoverflow 上试过这个解决方案： UserManager dependency injection with Owin and Simple Injector

这个在 simpleinjector 文档中： http://simpleinjector.readthedocs.io/en/latest/owinintegration.html

这对我不起作用（我没有BeginExecutionContextScope） WebApi + Simple Injector + OWIN

这是我的 startup.cs：

public class Startup
{
    public void Configuration(IAppBuilder app)
    {

        SimpleInjectorBootstrapper.Initialize();
        app.Use(async (context, next) => {
            using (AsyncScopedLifestyle.BeginScope(SharedLayer.Core.CoreObject.container))
            {
                await next();
            }
        });

        ConfigureOAuth(app);

        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        FilterConfig.RegisterHttpFilters(GlobalConfiguration.Configuration.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);


        HttpConfiguration config = new HttpConfiguration();
        WebApiConfig.Register(config);

        DependencyResolver.SetResolver(new SimpleInjectorDependencyResolver(SharedLayer.Core.CoreObject.container));
        config.DependencyResolver = new SimpleInjectorWebApiDependencyResolver(SharedLayer.Core.CoreObject.container);


        app.Use<ExceptionMiddleware>();
        app.Map(new PathString("/api"), application => { application.Use<AuthenticateMiddleware>(); });
        app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
        app.UseWebApi(config);

    }


    public void ConfigureOAuth(IAppBuilder app)
    {
        OAuthAuthorizationServerOptions OAuthServerOptions = new OAuthAuthorizationServerOptions()
        {
            AllowInsecureHttp = true,
            TokenEndpointPath = new PathString("/token"),
            AccessTokenExpireTimeSpan = TimeSpan.FromMinutes(30),
            Provider = new AuthorizationProvider(),
        };

        app.UseOAuthAuthorizationServer(OAuthServerOptions);
        app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions());
    }

}

这是我的 simpleinjector 引导程序：

public static class SimpleInjectorBootstrapper
{

    public static void Initialize()
    {
        // Create a new Simple Injector container
        var container = new Container();


        // Set default Scope
        container.Options.DefaultScopedLifestyle = new AsyncScopedLifestyle();


        // Configure the container (register)
        var businessAssembly = typeof(BusinessLayer.Bootstrap.SimpleInjectorBootstrapper).Assembly;


        // get services based on conditions
        var registerations = from type in businessAssembly.GetExportedTypes() 
                             where type.Namespace.Contains("BusinessLayer.Logic")
                             where type.GetInterfaces().Any()
                                select new 
                                { 
                                    Service = type.GetInterfaces().First(),
                                    Implementation = type
                                };



        // register each service
        foreach (var reg in registerations)
        {
            container.Register(reg.Service, reg.Implementation, Lifestyle.Scoped);
        }


        // init nested bootstrapper
        BusinessLayer.Bootstrap.SimpleInjectorBootstrapper.Initialize(container);


        // Register Root services
        container.RegisterMvcControllers(Assembly.GetExecutingAssembly());
        container.RegisterMvcIntegratedFilterProvider();
        container.RegisterWebApiControllers(GlobalConfiguration.Configuration);





        // Optionally verify the container's configuration.
        container.Verify();



        // Store the container for use by the application
        //DependencyResolver.SetResolver(new SimpleInjectorDependencyResolver(container));



        // Assign SimpleInjectorWebApiDependencyResolver to DependencyResolver 
        //GlobalConfiguration.Configuration.DependencyResolver = new SimpleInjectorWebApiDependencyResolver(container);



        // store container in a static variable for DI in class libraries
        SharedLayer.Core.CoreObject.container = container;


    }
}

当我评论这两行时，我的应用程序运行良好：

ConfigureOAuth(app);
app.Map(new PathString("/api"), application => { application.Use<AuthenticateMiddleware>(); });

我的错误在哪里？

编辑：

我发现当我评论这一行时，我的项目运行良好：

        app.Map(new PathString("/api"), application => {
            application.Use<AuthenticateMiddleware>();
        });

这是我的 AuthenticateMiddleware 代码：

public class AuthenticateMiddleware : OwinMiddleware
{
    public AuthenticateMiddleware(OwinMiddleware next)
    : base(next)
    {}

    public async override Task Invoke(IOwinContext context)
    {

        string username = "";


        if (context.Request.Method.Equals(HttpMethod.Get.Method))
        {
            if (context.Request.Query.Any(e => e.Key == "username" && e.Value != null))
                username = context.Request.Query.Get("username");
        }

        else
        {
            var body = new StreamReader(context.Request.Body).ReadToEndAsync().Result;
            var dict = HttpUtility.ParseQueryString(body);
            var json = new JavaScriptSerializer().Serialize(dict.AllKeys.Where(e => e.Equals("username")).ToDictionary(k => k, k => dict[k]));

            JObject jsonObject = JsonConvert.DeserializeObject<JObject>(json);
            username = jsonObject["username"] != null ? jsonObject["username"].ToString() : "";
        }


        if (username == "")
            throw new ArgumentNullException("username is required.");


        if (!context.Authentication.User.HasClaim("username", username))
            throw new SecurityException("token is invalid.");


        await Next.Invoke(context);

    }


}

在对我的项目提出挑战并将其搁置 2 周后，我找到了解决我所有问题的方法，谢谢@Steven

主要问题是 owin 映射。

我必须从路由定义中删除 api 段，我还不知道为什么，但它可以工作。谢谢@Tratcher

owin map extension return 404
