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

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
