接上節(jié)發(fā)送郵件，這次我們結(jié)合數(shù)據(jù)庫實(shí)現(xiàn)發(fā)送郵件驗(yàn)證碼
我們假設(shè)的是用戶注冊(cè)驗(yàn)證碼：

首先郵箱唯一，其次驗(yàn)證碼有有效期默認(rèn)一天

struct SKRegistVerfiy: SQLiteModel {
    var id: Int?
    var email: String 
    var verfiyCode: String =  VerfiyCodeRender.renderInstance.default
    var create: TimeInterval = Date().timeIntervalSince1970
    var expri: Double = 60 * 60 * 24
}
extension SKRegistVerfiy{
    
    /// 郵箱驗(yàn)證入庫
    ///
    /// - Parameters:
    ///   - email: 接受驗(yàn)證碼的郵箱
    ///   - code: 隨機(jī)驗(yàn)證碼 默認(rèn)6位數(shù)字
    ///   - expri: 有效期默認(rèn)1天
    init(email: String, verfiyCode code:String = VerfiyCodeRender.renderInstance.default, expri: Double = 24 * 60 * 60){
        let time = Date().timeIntervalSince1970
        self.init(id: nil,
                  email: email,
                  verfiyCode: code,
                  create: time,
                  expri: expri)
    }
}
extension SKRegistVerfiy{
    var isCodeAvailable: Bool{
        return Date().timeIntervalSince1970 - create <= expri
    }
    
    var message:String{
        return "您的確認(rèn)碼已經(jīng)發(fā)到：\(self.email) 確認(rèn)碼是:\(verfiyCode) 將在\(expri/(24*60*60))天過期"
    }
    
}

extension SKRegistVerfiy: All{}

All是個(gè)組合protocol:typealias All = Migration&Content&Parameter

我們需要在configure.swift中配置：migrations.add(model: SKRegistVerfiy.self, database: .sqlite)

整個(gè)是為了學(xué)習(xí)和理清思路，因此我們忽略了安全性：比如郵箱的明文存儲(chǔ)
