net core读取配置节

通过工具类 AppSettingsConfig

 services.AddSingleton(new AppSettingsConfig(configuration));

using Microsoft.Extensions.Configuration;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace  XXXXX.Common
{
    
    public class AppSettingsConfig
    {
        public static IConfiguration Configuration { get; set; }

        public AppSettingsConfig(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        /// <summary>
        /// 封装要操作的字符
        /// </summary>
        /// <param name="sections">节点配置</param>
        /// <returns></returns>
        public static string GetValue(params string[] sections)
        {
            try
            {
                if (sections.Any())
                {
                    return Configuration[string.Join(":", sections)];
                }
            }
            catch (Exception) { }
            return "";
        }

        /// <summary>
        /// 递归获取配置信息数组
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="sections"></param>
        /// <returns></returns>
        public static T GetEntity<T>(string sections)
        {
            T s = Activator.CreateInstance<T>();
            Configuration.Bind(sections, s);
            return s;
        }

        /// <summary>
        /// 获取连接字符串
        /// </summary>
        /// <param name="name"></param>
        /// <returns></returns>
        public static string GetConnectionString(string name)
        {
            return Configuration.GetConnectionString(name);
        }


    }

}

"APISetting": {
"Grant": "client_credentials"
},

使用：

var grant = AppSettingsConfig.GetValue("APISetting:Grant");

"Authentication": {
"QQ": {
"ClientId": "AA",
"ClientSecret": "AA"
}
}

直接读取

      options.ClientId = Configuration.GetValue<string>("Authentication:QQ:ClientId");
