安装依赖包

   > Com.Ctrip.Framework.Apollo                         2.10.0   2.10.0> Com.Ctrip.Framework.Apollo.ConfigAdapter.Yaml      2.9.0    2.9.0 > Com.Ctrip.Framework.Apollo.Configuration           2.10.2   2.10.2> Com.Ctrip.Framework.Apollo.ExtensionsHosting       2.10.1   2.10.1

修改appsettings.json

  "Apollo": {"AppId": "ellis","Env": "DEV","MetaServer": "http://192.168.214.133:30080","ConfigServer": [ "http://192.168.214.133:30080" ],}

添加配置类

using Com.Ctrip.Framework.Apollo.Internals;
using Microsoft.Extensions.Primitives;namespace CoreApollo
{public class MyConfigService{private readonly IConfiguration _configuration;public static Dictionary<string,string> configDictionary = new Dictionary<string, string>();public static object lockobj = new object();public MyConfigService(IConfiguration configuration){_configuration = configuration;// 监听配置变更ChangeToken.OnChange(() => _configuration.GetReloadToken(), OnConfigChanged);}public string GetConfig(string key){return  _configuration[key];}private void OnConfigChanged(){Console.WriteLine("Apollo configuration has changed!");lock(lockobj){foreach (var section in _configuration.AsEnumerable()){configDictionary[section.Key] = section.Value;}}Console.WriteLine("re init");}}
}

依赖注入

using Com.Ctrip.Framework.Apollo;
using CoreApollo;//YamlConfigAdapter.Register();var builder = WebApplication.CreateBuilder(args);builder.Configuration.AddApollo(builder.Configuration.GetSection("Apollo")).AddDefault();builder.Services.AddScoped<MyConfigService>();

controller

using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;namespace CoreApollo.Controllers
{[Route("api/[controller]/[action]")][ApiController]public class ApolloController : ControllerBase{private readonly IConfiguration _configuration;private readonly MyConfigService _myConfigService;public ApolloController(IConfiguration configuration, MyConfigService myConfigService){_configuration = configuration;_myConfigService = myConfigService;}[HttpGet]public IActionResult GetConfig(string key){var myConfigValue = _myConfigService.GetConfig(key);return Ok(myConfigValue);}}
}
