nodejs的querystring

querystring.stringify(‘要序列化的字符串’[,“分隔符”][,'键值对的连接符'"])

默认的分隔符是&，键值对连接符是=

1.序列化：

a代码： querystring.stringify({name:'zcw',hobby:['coding','pingpong']})

结果：name=zcw&hobby=coding&hobby=pingpong

b代码： querystring.stringify({name:'zcw',hobby:['coding','pingpong']},',')

结果：name=zcw,hobby=coding,hobby=pingpong

c代码：querystring.stringify({name:'zcw',hobby:['coding','pingpong']},',',':')

结果：'name:zcw,hobby:coding,hobby:pingpong'

2.反序列化：querystring.parse('反序列化string'[,"分隔符"][,'键值对的连接符'])

代码：querystring.parse('name=zcw,hobby=coding,hobby=pingpong',',')

{ name: 'zcw', hobby: [ 'coding', 'pingpong' ] }

3.转义

querystring.escape('<jjj')

结果：%3Cjjj

4.反转义

querystring.unescape('%3Cjjj')
