如何指定环境，请看启动参数

//新API创建  configuration := configuration.YAML("config")
configuration := abstractions.NewConfigurationBuilder().AddYamlFile("config").Build()
// 添加环境为Prod的配置文件 config_prod.yml 
YoyoGo.NewWebHostBuilder().
       UseConfiguration(configuration).
       Configure(func(app *YoyoGo.WebApplicationBuilder) {
		   app.UseStaticAssets()       //添加静态资源
		   app.UseEndpoints(registerEndpointRouterConfig)  //api 路由
       }).Build().Run()
