Apollo配置

50丨配置：使用分布式配置中心方案版本化管理配置

一、Apollo配置

Nuget:

Com.Ctrip.Framework.Apollo.Configuration

public class Program
{
    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }
    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureAppConfiguration((hostBuilderContext, configurationBuilder) =>
            {
            //阿波罗日志输出级别
            LogManager.UseConsoleLogging(Com.Ctrip.Framework.Apollo.Logging.LogLevel.Trace);
            //var c = configurationBuilder.Build().GetSection("Apollo").Get<ApolloOptions>();
            //注入阿波罗配置
            configurationBuilder.AddApollo(configurationBuilder.Build().GetSection("Apollo"))
                //.AddDefault(Com.Ctrip.Framework.Apollo.Enums.ConfigFileFormat.Json)
                .AddDefault()
                .AddNamespace("app-aidemo4438", Com.Ctrip.Framework.Apollo.Enums.ConfigFileFormat.Json)
                .AddNamespace("application", Com.Ctrip.Framework.Apollo.Enums.ConfigFileFormat.Properties);

            //本地如果有值覆盖apollo
            //optional:false 文件不存在报错
            //reloadOnChange:true  文件变更重新加载配置
            configurationBuilder.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
            //最下面的一个文件 覆盖前一个文件
            configurationBuilder.AddJsonFile("test.json", optional: false, reloadOnChange: true);
            })
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.UseStartup<Startup>();
            });
}

appsetting

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "abc": "loc-abc",
    "RedisCache//": {
      "Configuration": "192.168.198.128:6379",
      "InstanceName": "GoodSite"
    },
  "Apollo": {
    "AppId//": "配置中心唯一标识",
    "AppId": "apidemo4438",
    "Env//": "环境",
    "Env": "DEV",
    "MetaServer": "http://106.54.227.205:8080/",
    "ConfigServer//": "这个是协程的示例地址",
    "ConfigServer": [ "http://106.54.227.205:8080/" ]
  },
  "AllowedHosts": "*"
}

二、DotNet Core 使用 IOptions 读取配置文件

appsettings.json:

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*",
  "HC": {
    "Redis": {
      "aa": "1"
    },
    "DB": {
      "bb": 2
    }
  }
}

Startup.cs:

services.Configure<Test>(Configuration.GetSection("HC"));

Test.cs(model):

public class Test
    {
        public Redis Redis { get; set; }
        public DB DB { get; set; }
    }
    public class Redis
    {
        public string aa { get; set; }
    }
    public class DB
    {
        public string bb { get; set; }
    }

调用：

public Test Test { get; set; }

        public api1Controller(IOptions<Test> options)
        {
            Test = options.Value;
        }
