使用OWIN SelfHost时,请致电httpclient抛出404响应



我有以下对自我主持的owin api的呼吁:

const string baseAddress = "http://localhost:9000/";
using (WebApp.Start<ApiSelfHost>(url: baseAddress))
{
    var client = new HttpClient();
    var response = client.GetAsync(baseAddress + "api/v1/orders/test/status").Result;
}

基于(我得到的工作(:

使用owin到自宿主asp.net web api

响应返回以下内容:

状态代码:404,理性词:'找不到'

但是,如果我运行实际的API并转到:

http://localhost:51823/api/v1/orders/test/status

我得到有效的响应。

该控制器动作具有此签名:

[HttpGet]
[Route("api/v1/orders/{orderReference}/status")]
public IHttpActionResult GetOrderStatus([FromUri]string orderReference)

我尝试将该端口9000更改为51823,但这没关系。

我安装了以下OWIN软件包:

<package id="Microsoft.Owin" version="4.0.1" targetFramework="net471" />
<package id="Microsoft.Owin.Host.HttpListener" version="4.0.1" targetFramework="net471" />
<package id="Microsoft.Owin.Hosting" version="4.0.1" targetFramework="net471" />
<package id="Microsoft.Owin.Security" version="3.0.1" targetFramework="net471" />
<package id="Microsoft.Owin.Security.Jwt" version="3.0.1" targetFramework="net471" />
<package id="Microsoft.Owin.Security.OAuth" version="3.0.1" targetFramework="net471" />
<package id="Microsoft.Owin.Testing" version="4.0.1" targetFramework="net471" />

问题

任何指示为什么找不到URL(抛出404(?

几个小时后,我才能使用它!正如预期的那样,这是更深的东西:

我的控制器给出了此错误:

no parameterless constructor defined for this object

尽管设置了IOC类型注册:

source.Register(c => MyDbContextMock.Create())
    .AsImplementedInterfaces()
    .InstancePerRequest();

我错过了这一行:

source.RegisterApiControllers(typeof(OrderController).Assembly);

完整的启动设置为注入:

public class ApiSelfHost : Startup
{
    public override void Configuration(IAppBuilder app)
    {
        app.UseCors(CorsOptions.AllowAll);
        var httpConfiguration = new HttpConfiguration();
        var container = httpConfiguration.ConfigureAutofac();
        app.UseAutofacMiddleware(container);
        app.UseAutofacWebApi(httpConfiguration);
        app.UseWebApi(httpConfiguration);
    }
}

其中ConfigureAutofacHttpConfiguration上的扩展名:

internal static IContainer ConfigureAutofac(this HttpConfiguration source)
{
    var container = new ContainerBuilder()
        .ConfigureAutofac()
        .Build();
    source.ConfigureDependencyInjection(container);
    return container;
}

也在ContainerBuilder上:

internal static ContainerBuilder ConfigureAutofac(this ContainerBuilder source)
{
    source.RegisterApiControllers(typeof(OrderController).Assembly);
    source.Register(c => MyDbContextMock.Create())
        .AsImplementedInterfaces()
        .InstancePerRequest();
    return source;
}

Startup基类是API的实际理由。
