Nodejs使用coffeescript编写的用户注册/登陆代码(MySQL)

记录一下，以备后用

Settings = require '../../settings.js'



exports.register = (req, res) ->



  nick_name = req.body.nick_name

  email = req.body.email

  password = req.body.password



  # 配置变量

  table_name = 'user_info'

  database = Settings.mysql.database



  # 获取当前时间

  dateObj = new Date()



  year = dateObj.getFullYear()

  month = dateObj.getMonth() + 1

  day = dateObj.getDate()

  hour = dateObj.getHours()

  min = dateObj.getMinutes()

  sec = dateObj.getSeconds()



  console.log month.length

  date_str = year + '-' + month + '-' + day + ' ' + hour + ':' + min + ':' + sec

  #console.log date_str



  # 选择使用的数据库

  mysqldb.query('USE ' + database)



  # 判断邮箱，进行注册

  sql = "select * from " + table_name + " where email = '" + email + "'"

  console.log sql

  mysqldb.query(sql, (err, data) ->

    if (err)

      return res.jsonp({"status":-1, "message":"数据库出错"})

    else

      if (data.length > 0)

        return res.jsonp({"status":-2, "message":"邮箱已经存在"})

      else

        sql = "select * from " + table_name + " where nick_name = '" + nick_name + "'"

        mysqldb.query(sql, (err, data) ->

          if (data.length > 0)

            return res.jsonp({"status":-3, "message":"昵称已存在"})

          else

            mysqldb.query(

              'INSERT INTO ' + table_name + ' SET nick_name = ?, email = ?, ctime = ?, password = ?',

              [nick_name, email, date_str, password])

            return res.jsonp({"status":0, "message":"注册成功"})

        )

  )



exports.login = (req, res) ->



  email = req.body.email

  password = req.body.password



  # 配置变量

    else

      if (data.length == 0)

        return res.jsonp({"status":-2, "message":"用户不存在"})

      else

        if (data[0].password == password)

          return res.jsonp({"status":0, "message":"登陆成功"})

        else

          return res.jsonp({"status":-3, "message":"用户名或密码错误"})
