如何在使用 Http.sys 和 URLPrefix 时配置 dotnet core 3 以提供 React SPA？

Question

更改 URLPrefix 后出现以下错误：

The SPA default page middleware could not return the default page '/index.html' because it was not found, and no other middleware handled the request.

因此需要一些东西来告诉 dotnet 核心有关前缀的信息，但我似乎找不到正确的设置组合。

非常感谢帮助。

代码如下：

HostBuilder 设置为：

public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
    .ConfigureWebHostDefaults(webBuilder =>
    {
        webBuilder.UseHttpSys(options =>
        {
            options.AllowSynchronousIO = false;
            options.Authentication.Schemes = AuthenticationSchemes.None;
            options.Authentication.AllowAnonymous = true;
            options.MaxConnections = null;
            options.MaxRequestBodySize = 30000000;
            options.UrlPrefixes.Add("http://localhost:5005/Product/Site");
        });
        webBuilder.UseStartup<Startup>();
    });

配置服务：

public override void ConfigureServices(IServiceCollection services)
{
  services.AddRazorPages();

  services.AddSpaStaticFiles(configuration =>
  {
    configuration.RootPath = "ClientApp/build";
  });

  services.AddMvc();
  services.AddResponseCompression(opts =>
  {
    opts.MimeTypes = ResponseCompressionDefaults.MimeTypes.Concat(
              new[] { "application/octet-stream" });
  });
}

然后Configure是：

      app.UseSpaStaticFiles();
      app.UseRouting();
      app.UseEndpoints
      (
        endpoints =>
        {
          endpoints.MapControllerRoute(
              name: "default",
              pattern: "{controller}/{action=Index}/{id?}");
        }
      );

      app.UseSpa(spa =>
      {
        //spa.Options.DefaultPage = reactPath + "/index.html";
        spa.Options.DefaultPage = "/index.html";

        spa.Options.SourcePath = "ClientApp";


      });

这似乎是实际静态文件路径丢失的问题。在您的 StaticFilesOptions 中，确保您为文件提供者提供 index.html 静态文件的路径。

spa.Options.DefaultPageStaticFileOptions = new StaticFileOptions
            {
              FileProvider = new PhysicalFileProvider
              (
                @"<YourPath>"
              )
            }
