Question

我在开发.net核心应用程序时可以正常工作，但是当我发布应用程序并在IIS上部署时，下面的图片显示了错误。我在这个问题上花了5 6个小时，但没有成功，任何人都可以帮助我。为什么它会显示此错误，而我却错误地引导了我

  public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Error");
                app.UseHsts();
            }

            app.UseHttpsRedirection();
            app.UseStaticFiles();
           // app.UseSpaStaticFiles();

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller}/{action=Index}/{id?}");
            });

            app.UseSpa(spa =>
            {
                // To learn more about options for serving an Angular SPA from ASP.NET Core,
                // see https://go.microsoft.com/fwlink/?linkid=864501

                spa.Options.SourcePath = "ClientApp";

                if (env.IsDevelopment())
                {
                   spa.UseAngularCliServer(npmScript: "start");
                }
            });
        }

经过一天的研究，在这里https://github.com/aspnet/AspNetCore/issues/5238找到了适合我的解决方案正如@boonmathew所指出的。解决方案是确保启动文件中的rootpath

// In production, the Angular files will be served from this directory
services.AddSpaStaticFiles(configuration =>
{
   configuration.RootPath = "ClientApp/dist";
});

匹配了angular.json文件中的输出路径 "outputPath": "dist",

另外，由于您看到该消息，因此如果使用的是右键单击发布，请确保将您的部署设置更改为ASPNETCORE_ENVIRONMENT到Production

edit app settings

environment definition

这就是为我解决的问题。祝你好运！
