c# - 从控制台应用程序启动 ASP.NET Core Web API

Question

我想将 ASP.NET Core WebApi 集成到包含许多其他项目的解决方案中。(我使用的是 dotnet 6.0)在解决方案中，WebAPI 由 Main 项目作为 Thread 启动。问题是，如果我从其他项目运行 WebApi，则只会启动一个空的 WebApi。 (使用默认端口，而不是配置的端口，并且没有 Controller ...)

谁能帮帮我？

这是我上面描述的相同问题的最小解决方案:

WebApi 是默认的 VisualStudio 2022 项目。我只对 Program.cs 文件做了一些小改动。这是 WebApi 项目的 Program.cs 文件的代码:

namespace WebApi;

public class Program
{
    public static void Main(string[] args)
    {
        var builder = WebApplication.CreateBuilder(args);

        // Add services to the container.

        builder.Services.AddControllers();
        // Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
        builder.Services.AddEndpointsApiExplorer();
        builder.Services.AddSwaggerGen();

        var app = builder.Build();

        // Configure the HTTP request pipeline.
        if (app.Environment.IsDevelopment())
        {
            app.UseSwagger();
            app.UseSwaggerUI();
        }

        app.UseHttpsRedirection();

        app.UseAuthorization();

        app.MapControllers();

        app.Run();
    }
}

主工程Programm.cs代码:

using WebApi;

internal class Program
{
    private static void Main(string[] args)
    {
        Console.WriteLine("Hello, World!");
        WebApi.Program.Main(Array.Empty<string>());
    }
}

launchSettings.json

{
  "$schema": "https://json.schemastore.org/launchsettings.json",
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:56423",
      "sslPort": 44385
    }
  },
  "profiles": {
    "WebApi": {
      "commandName": "Project",
      "dotnetRunMessages": true,
      "launchBrowser": true,
      "launchUrl": "swagger",
      "applicationUrl": "https://localhost:7257;http://localhost:5257",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

这是我从主项目运行 WebApi 时的样子:

Hello, World!
info: Microsoft.Hosting.Lifetime[14]
      Now listening on: http://localhost:5000
info: Microsoft.Hosting.Lifetime[14]
      Now listening on: https://localhost:5001
info: Microsoft.Hosting.Lifetime[0]
      Application started. Press Ctrl+C to shut down.
info: Microsoft.Hosting.Lifetime[0]
      Hosting environment: Production
info: Microsoft.Hosting.Lifetime[0]
      Content root path: C:\data\Experimental\CallWebApiFromOtherProject\Main\bin\Debug\net6.0\

( Controller 和 Swagger 不可用。端口也不是上面定义的端口。-> 只有一个没有任何东西的 Web 服务器)

我做错了什么？

Answer 1

部分配置丢失，因为你从其他项目启动webapi您可以在 WebApi 的 main 方法中尝试如下:

Directory.SetCurrentDirectory(@"the directory of WebApi Project");
var builder = WebApplication.CreateBuilder(new WebApplicationOptions() { EnvironmentName= "Development",ApplicationName="WebApi"});

现在，它在我的情况下运行良好:
