## 2. nodejs koa发送邮箱验证码： ##

const nodemailer = require('nodemailer')
    
    const userEmail = 'xxxx@163.com'
    const transporter = nodemailer.createTransport({ 
      service: '163',
      secureConnection: true,
      auth: { 
        user: userEmail,
        pass: 'MBZYT***OJMKO'  //这个是开启`POP3/SMTP/IMAP`的授权码
      }
    })
    
    router.get('/sendcode', async ctx => { 
        const email = ctx.query.email
        // 记得检测该 email 是否已注册
        const code = Math.random().toString().slice(2,6)
        ctx.session.emailcode = code //随机验证码
    	const mailOptions = { 
          from: userEmail,
          cc: userEmail,
          to: email,
          subject: '验证码',
          text: '说明内容',
          html: '<h2>【小米官方】</h2>验证码：<span>${code}</span>'
        }
    	try { 
          await transporter.sendMail(mailOptions)
          ctx.body = { 
    	      code: 0,
    	      message: '邮箱验证码发送成功！',
    	  }
        } catch(e) { 
    	  ctx.body = { 
    	      code: -1,
    	      message: '邮箱验证码发送失败！',
    	  }
        }
    })
    
    // 登录时判断验证码是否一致即可
    router.post('/login', async ctx => { 
    	const {  email, emailcode } = ctx.request.body
        if (emailcode !== ctx.session.emailcode) { 
          ctx.body = { 
    	      code: -1,
    	      message: '邮箱验证码错误！',
    	  }
          return
        }
    }
