                  //方式一：自定义设置返回内容
                  g.Response.ContentType = "text/html;charset=utf-8";
                  await g.Response.WriteAsync("欢迎使用webapi<br/>  <a href=\\"/swagger\\" target=\\"_blank\\">webapi接口swagger文档</a>");

				  //方式二：重定向url
                  //g.Response.Redirect("/swagger");
                  //await Task.CompletedTask;
