基于Golang开发一个轻量级登录库/框架

type Enforcer struct {
    // 从配置文件读取配置需要
    conf         string
    // 登录类型
    loginType    string
    config       config.TokenConfig
    // 生成token的函数
    generateFunc model.GenerateTokenFunc
    // 用于存储数据
    adapter      persist.Adapter
    // 监听器
    watcher      persist.Watcher
    // 用于记录日志
    logger       log.Logger
}
