 public class JwtSettingsOptions

    {

        public const string JwtSettings = "JwtSettings";

        /// <summary>

        /// 发行人

        /// </summary>

        public string Issuer { get; set; }

        /// <summary>

        /// 订阅者

        /// </summary>

        public string Audience { get; set; }

        /// <summary>

        /// 加密key

        /// </summary>

        public string SecurityKey { get; set; }

        /// <summary>

        /// 过期分钟

        /// </summary>

        public int ExpMinutes { get; set; }

    }

方法1

services.AddOptions<JwtSettingsOptions>().Bind(Configuration.GetSection(JwtSettingsOptions.JwtSettings));

方法2

var jwtSettingsOptions = new JwtSettingsOptions();

Configuration.GetSection(JwtSettingsOptions.JwtSettings).Bind(positionOptions);

方法3
//使用 ConfigurationBinder.Get 可能比使用 ConfigurationBinder.Bind 更方便。

var jwtSettingsOptions = new JwtSettingsOptions();

jwtSettingsOptions = Configuration.GetSection(JwtSettingsOptions.JwtSettings).Get<JwtSettingsOptions>();

appsettings.json

{

  "JwtSettings": {

    "SecurityKey": "BB3647441FF3333A4B5D344B4E64A29B53CE525",

    "Audience": "autience",

    "Issuer": "isuser",

    "ExpMinutes": 120

  }

}

通过构造函数获取实例

private IOptions<JwtSettingsOptions> _options;

public HomeController( IOptions<JwtSettingsOptions> options)
{
　　_options = options;

 JwtSettingsOptions  jwtSetting =_options.Value;

}
