    主要配置：

?

1 2	builder.Services.AddNacosAspNet(builder.Configuration, section: "Nacos"); builder.Host.UseNacosConfig("Nacos", logAction: x => x.AddSerilog());

　PS:注意一下，我看了很多文档都说，直接使用IConfiguration 文件的 Get 就能获取的 nacos 的配置，这个是错误的，反正我这边测试是行不通的，必须使用 builder.Services.Configure<UserInfo>(builder.Configuration.GetSection("UserInfo"));  然后用  IOptions<UserInfo> options 才能拿到值，错误范例如下：

 

 

 

6-创建一个控制器，开始使用nacos配置
