前端学习（四）node核心模块querystring

querystring可处理键值对的对象和字符串

querystring
{ unescapeBuffer: [Function: unescapeBuffer],
  unescape: [Function: qsUnescape],
  escape: [Function: qsEscape],
  stringify: [Function: stringify],
  encode: [Function: stringify],
  parse: [Function: parse],
  decode: [Function: parse] }

querystring.stringify({name : "myName",course : ["java", "node"], home : "", "&", "="});  //将参数对象(query对象)序列化为一个字符串
"myName=course&course=java&course=node&home="

querystring.parse("字符串","键值对间的连接符","键值间的连接符","Max,默认1000,设为0则无限制");  //反序列化为参数对象

querystring.escape("string");  //字符串转义
'string'

querystring.unescape("sting");  //反转义为字符串
'string'
