将 Web API 控制器端点添加到 Kestrel 工作器项目 [英] Add Web API controller endpoint to Kestrel worker project

问题描述

我有一个带有 TCP 管道的 .NET Core 工作程序项目，并且想向其中添加一个 HTTP 控制器端点.我基本上

I have a .NET Core worker project with TCP pipelines and want to add one HTTP controller endpoint to it. I basically

• 创建了一个新的工人项目(用于复制目的)
• 在它的 csproj 文件中，我添加了 到项目组以访问 webbuilder 的东西
• 安装包Microsoft.AspNetCore.Mvc.Core
• 创建了一个Startup类

• created a new worker project (for reproduction purposes)
• in its csproj file I added <FrameworkReference Include="Microsoft.AspNetCore.App" /> to the item group to gain access to the webbuilder stuff
• installed the package Microsoft.AspNetCore.Mvc.Core
• created a Startup class

.

internal class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc(); // not sure if I even need this
        services.AddControllers();
    }

    public void Configure(IApplicationBuilder applicationBuilder)
    {
        applicationBuilder.UseRouting();
        applicationBuilder.UseEndpoints(endpoints => { endpoints.MapControllers(); });
    }
}

• 在 Program 类中配置 Kestrel
• configured Kestrel in the Program class

.

public class Program
{
    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureWebHostDefaults(webHostBuilder =>
            {
                webHostBuilder.UseKestrel(kestrelServerOptions =>
                {
                    kestrelServerOptions.ListenLocalhost(5000); // this will be a config value
                }).UseStartup<Startup>();
            })
            .ConfigureServices((hostContext, services) =>
            {
                services.AddHostedService<Worker>();
            });
}

• 创建了一个用于测试目的的控制器

.

[ApiController]
[Route("[controller]")]
internal class UsersController : ControllerBase
{
    [HttpGet]
    public async Task<ActionResult> Test()
    {
        return Ok();
    }
}

• 我运行该项目并调用 GET http://localhost:5000/users
• 我希望得到 200 但得到 404 并且调试器没有命中控制器端点

有人知道我错过了什么吗?

Does someone know what I'm missing?

推荐答案

如果你想让它起作用，你需要在方法上指定默认路由

You need to specify the default route on method if you want this to be work

[ApiController]
[Route("[controller]")]
   public class UsersController : ControllerBase
    {
     [Route("")]
     [HttpGet]
     public async Task<ActionResult> Test()
       {
          return Ok();
       } 
    }

第二件事是公开控制器
