Question

我有一个控制台应用程序（ NET Core 2.2 ），该应用程序的主要功能在cli中。但我想在其上调用rest api端点（以获取有关此应用程序的一些信息）。现在，我将代码实现到Program.cs中，添加一个Startup.cs和一个控制器。但是我无法通过邮递员联系我的管理员。缺少什么？

Program.cs：

public static void Main(string[] args)
{
    CreateWebHostBuilder(args).Build().Run();
    // further logick...
}

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
            .UseStartup<Startup>()
            .UseUrls("http://0.0.0.0:5002");

Startup.cs：

public class Startup
{
    public IConfiguration Configuration { get; }

    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddBusinessComponents();
        services.AddMvc();
    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        app.UseMvc();
    }
}

控制器：

[Produces("application/json")]
[Route("cli/v1/dataPicker/info")]
public class InfoController : Controller
{
    private IInfoBusinessComponent BusinessComponent { get; }

    [Microsoft.AspNetCore.Mvc.HttpGet]
    public async Task<IActionResult> GetInfoAsync()
    {
        Statuses statuses = null;
        try
        {
            statuses = await BusinessComponent.GetInfo();
        }
        catch (System.Exception ex)
        {
            return BadRequest($"Exception occurred while trying to get health informations.");
        }

        return Ok(statuses);
    }
}

以下是我的邮递员回复：

Answer 1

尝试：

[Route("api/[controller]")]
[ApiController]
public class InfoController : Controller
{ 
    [HttpGet("GetInfo")]
    public async Task<IActionResult> GetInfoAsync()
    {
        Statuses statuses = null;
        try
        {
            statuses = await BusinessComponent.GetInfo();
        }
        catch (System.Exception ex)
        {
            return BadRequest($"Exception occurred while trying to get health informations.");
        }

        return Ok(statuses);
    }
}

并在浏览器中调用它，如：

http://localhost:5002/api/Info/GetInfo

Answer 2

我需要在launchSettings.json中添加行（launchBrowser和applicationUrl）：

{
  "profiles": {
    "DataPicker.Cli": {
      "commandName": "Project",
      "launchBrowser": true,
      "environmentVariables": {
        "Key": "Value",
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
      "applicationUrl": "http://localhost:5003/"
    }
  }
}

现在，我可以通过浏览器甚至是Swagger来访问我的API。：-）
