  是不是使用的是net core 3+？课程是基于2.2的，所以会跟3+有所不同。试试： "services.AddMvc(option => option.EnableEndpointRouting = false) .AddNewtonsoftJson();", 意思就是默认禁用Endpoint Routing

  感觉像是依赖没添加，截图留下startup文件代码，我可以仔细看看。

  要把

  endpoints.MapGet("/", async context =>

                  {

                      await context.Response.WriteAsync("Hello World!");

                  });

  这句话删掉，否则就会覆盖HomeController里的设置

   app.UseEndpoints(endpoints =>

              {

                  endpoints.MapGet("/", async context =>

                  {

                      await context.Response.WriteAsync("Hello World!");

                  });

  
  

                  endpoints.MapDefaultControllerRoute();

              });

  3.1版本,这么写就OK啦,很简单!

  public void Configure(IApplicationBuilder app, IWebHostEnvironment env)

          {

              if (env.IsDevelopment())

              {

                  app.UseDeveloperExceptionPage();

              }

  
  

              app.UseRouting();

  
  

              app.UseEndpoints(endpoints =>

              {

                  endpoints.MapGet("/", async context =>

                  {

                      await context.Response.WriteAsync("Hello World!");

                  });

  
  

                  endpoints.MapControllerRoute(

                      name: "default",

                      pattern: "{controller=Home}/{action=Index}/{id?}");

              });

          }

  这是asp.net core 3.1的添加方法,用这个就行了
