.NET 发布的应用程序运行与开发不同的端口

Question

当我调试 React .NET 项目时，会打开两个终端。一种用于 React，一种用于 .NET 后端。 现在，当我将应用程序发布到文件夹时，我会得到一个 wwwroot 和运行时文件夹、一大堆 dll 和一个 exe 文件。

所以我知道一个终端不再出现，因为 React 应用程序现在只是一个像普通 html 网站一样的文件夹。

当我调试网站时，我得到：

info: Microsoft.Hosting.Lifetime[14]
      Now listening on: https://localhost:7291
info: Microsoft.Hosting.Lifetime[14]
      Now listening on: http://localhost:5026
info: Microsoft.Hosting.Lifetime[0]
      Application started. Press Ctrl+C to shut down.
info: Microsoft.Hosting.Lifetime[0]
      Hosting environment: Development
info: Microsoft.Hosting.Lifetime[0]
      Content root path: C:\Users\renek\source\ReactNet\ReactNet
info: Microsoft.AspNetCore.SpaProxy.SpaProxyLaunchManager[0]
      No SPA development server running at https://localhost:44411 found.
info: Microsoft.AspNetCore.SpaProxy.SpaProxyMiddleware[0]
      SPA proxy is not ready. Returning temporary landing page.
info: Microsoft.AspNetCore.SpaProxy.SpaProxyMiddleware[0]
      SPA proxy is ready. Redirecting to https://localhost:44411.
info: Microsoft.AspNetCore.SpaProxy.SpaProxyLaunchManager[0]
      SPA development server running at 'https://localhost:44411'

现在，当我将项目发布到我的 VPS 并运行 exe 时：

info: Microsoft.Hosting.Lifetime[14]
      Now listening on: http://localhost:5000
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:\inetpub

有人可以解释一下我如何才能获得相同的设置吗？

到目前为止我尝试过的：

• Launchsettings.json 将值从 Development 更改为 Production：

{
  "profiles": {
    "ReactNet": {
      "commandName": "Project",
      "launchBrowser": false, // True originally
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Production", // Development originally
        "ASPNETCORE_HOSTINGSTARTUPASSEMBLIES": "Microsoft.AspNetCore.SpaProxy"
      },
      "applicationUrl": "https://localhost:7291;http://localhost:5026"
    },
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": false, // True originally
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Production", // Development originally
        "ASPNETCORE_HOSTINGSTARTUPASSEMBLIES": "Microsoft.AspNetCore.SpaProxy"
      }
    }
  },
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:32385",
      "sslPort": 44344
    }
  }
}

是的，我知道编辑 launchSettings 仅用于开发。这是我实际上要发布的第一个项目，所以不要责怪我不知道具体如何做。

如果您想在运行.exe文件时保留端口，您可以尝试：

var builder = WebApplication.CreateBuilder(args);
builder.WebHost.UseUrls("http://localhost:5026;https://localhost:7291");

这是文档相关
