ASP.NET 运行局域网访问

注意

注意：launchSettings.json 在开发环境优先级高于 appsettings.json

打开 properties 文件夹下面的 launchSettings.json 然后使用 "applicationUrl": "http://0.0.0.0:5059"。

下面是例子：

{
  "$schema": "https://json.schemastore.org/launchsettings.json",
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:15455",
      "sslPort": 0
    }
  },
  "profiles": {
    "SimpleApi": {
      "commandName": "Project",
      "dotnetRunMessages": true,
      "launchBrowser": true,
      "launchUrl": "swagger",
      "applicationUrl": "http://0.0.0.0:5059",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

打包 EXE 设置端口（硬编码）

var builder = WebApplication.CreateBuilder(args);
builder.WebHost.UseUrls("http://*:3045");
var app = builder.Build();

app.MapGet("/", () => "Hello World!");

app.Run();

打包后配置 URL

在 appsettings.json 设置 URL：

{
  "appName": "mock name",
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "AllowedHosts": "*",
  "Urls": "http://*:5411"
}

前提是没有在代码中硬编码：

builder.WebHost.UseUrls("http://*:3045");

读取 appsettings.json 的配置

ConfService.cs

public class ConfService
{
    private readonly IConfiguration _cfg;
    public ConfService(IConfiguration cfg) => _cfg = cfg;

    public void Foo()
    {
        // 支持冒号分层
        string conn = _cfg["BookStoreDatabase:ConnectionString"];
        string db = _cfg["appName"];
        Console.WriteLine(db);
    }
}

Program.cs

builder.Services.AddSingleton<ConfService>();

然后在 Controller 使用

[ApiController]
[Route("/index")]
public class IndexController : ControllerBase
{
    private readonly ConfService _confService;
    public IndexController(ConfService confService)
    {
        _confService = confService;
    }

    [HttpGet("/count")]
    public int Index()
    {
        _confService.Foo();
        return 1222;
    }
}
