使用 Owin 和 Web API 和 SimpleInjectionor 无法找到该资源

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，并且我收到 404 错误并显示"找不到资源"消息。

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

简单注射器作为 DI 和 ASP.NET 5

我在StackOverflow上尝试了这个解决方案： 用户管理器依赖注入与 Owin 和简单注入器

这个在简单喷油器文档中： http://simpleinjector.readthedocs.io/en/latest/owinintegration.html

而这一剂对我不起作用(我没有BeginExecutionContextScope( WebApi + Simple Injector + OWIN

这是我的创业公司.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());
}
}

这是我的简单注射器引导程序：

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，我的应用程序工作正常：

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，我的项目工作正常：

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

这是我的身份验证中间件代码：

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);
}

}

在挑战我的项目并离开了 2 周之后，我找到了解决所有问题的方法，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，但它有效。 谢谢@Tratcher
