.Net Core 读取appsettings.json的配置

在.net core中是没有*.config 文件的 配置文件都是*.json

1、在project.json里下面这行代码

"Microsoft.Extensions.Options.ConfigurationExtensions": "1.0.0",

然后修改 appsettings.json 添加Redis配置

  //用户配置信息
  "AppSettings": {
    //Redis缓存
    "RedisCaching": {
      "Enabled": true,
      "ConnectionString": "10.18.200.177:6379"
    }
  }

2、新建一个AppSettings对象来对应配置文件信息

    /// <summary>
    /// 配置文件
    /// </summary>
    public class AppSettings
    {
        public RedisCaching RedisCaching { get; set; }
    }
    /// <summary>
    /// Redis
    /// </summary>
    public class RedisCaching {
        /// <summary>
        /// 是否启用
        /// </summary>
        public bool Enabled { get; set; }
        /// <summary>
        /// 链接信息
        /// </summary>
        public string ConnectionString { get; set; }
    }

3、在Startup.cs里配置，首先用AddOptions() 初始化注入IOptions<T>，然后Configure<AppSettings>则是自动初始化AppSettings实例并且映射appSettings里的配置

services.AddOptions();
services.Configure<AppSettings>(Configuration.GetSection("AppSettings"));

4、使用
