.net core 集成nacos 并且 使用ocelot 网关集成nacos

nuget 下载

nacos-sdk-csharp.Extensions.Configuration

 

docker 安装 nacos 现在高版本的nacos 与低版本 有些不一样 开放了端口  9848，9849 用于grpc通信

docker run --name nacos \
-e MODE=standalone \
-p 8848:8848 -d \
-p 9848:9848   \
-p 9849:9849 \
--restart always nacos/nacos-server:latest 

页面 访问地址 是

http://192.168.0.196:8848/

在nacos中设置 配置文件

 

  "nacos": {
    "ServerAddresses": [ "http://192.168.0.196:8848" ],
    "DefaultTimeOut": 15000,
    "Namespace": "OderService",
    "ListenInterval": 1500,
    "ServiceName": "OderService",
    "GroupName": "DEFAULT_GROUP",
    "ClusterName": "DEFAULT",
    "RegisterEnabled": true,
    "InstanceEnabled": true,
    "ConfigUseRpc": true,
    "NamingUseRpc": true,
    "Ephemeral": true,
    "LBStrategy": "WeightRoundRobin"
  },

接下来是 .net core 配置 读取

appsettings.json 设置 

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*",
  "NacosConfig": {
    "Listeners": [
      {
        "Optional": false,
        "DataId": "OderService",
        "Group": "DEFAULT_GROUP"
      }
    ],
    "Optional": false,
    "Tenant": "fa6bd7e2-ff16-4faf-b0f6-c6a3e0c509fa",
    "ServerAddresses": [ "http://192.168.0.196:8848/" ]
  }
}

 

namespace NacosAPI
{
    public class Program
    {
        public static void Main(string[] args)
        {
            CreateHostBuilder(args).Build().Run();
        }

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureAppConfiguration((context, buider) =>
                {
                    buider.AddDefualtNacos();
                })
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                });
    }
}

 

nacos扩展

using Microsoft.Extensions.Configuration;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.CompilerServices;
using System.Text;
using System.Threading.Tasks;

namespace Microsoft.Extensions.Configuration
{
    public static class NacosExtend
    {
        public static void AddDefualtNacos(this IConfigurationBuilder builder,string nacosConfigStr= "NacosConfig")
        {
            builder.AddNacosV2Configuration(builder.Build().GetSection(nacosConfigStr));
        }
    }
}

读取 我在nacos控制台添加了

 如果能读取就是成功

            {
                app.UseDeveloperExceptionPage();

                app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "NacosAPI v1"));
            }

            app.UseHttpsRedirection();

            app.UseRouting();

            app.UseAuthorization();

            app.UseEndpoints(endpoints =>

            });
        }
    }
}

成功读取
