NodeJS学习第一季-路由规则

1、req.query 处理GET请求 ，获取GET参数

//GET /search?q=tobi+ferret

req.query.q

//=>"tobi ferret"

//GET /shoes?order=desc&shoe[color]=blue&shoe[type]=converse

req.query.order

//=>"desc"

req.query.shoe.color

//=>"blue"

2、req.body 处理POST请求，获取POST参数

//POST user[name]=tobi&user[email]=tobi@qq.com

req.body.user.name

//=>"tobi"

//POST {"name": "tobi"}

req.body.name

//=>"tobi"

3、req.params 处理/xxx形式的GET/POST请求

//GET /user/tj

req.params.user

//=>"tj"

//GET /js/javascript/jquery.js

req.params[0]

//=>"javascript/jquery.js"

4、req.param() 处理GET/POST请求，但查找优先级由高到低为 req.params-->req.body-->req.query

//?name=tobi

req.param('name')

//=>"tobi"

//POST name=tobi

req.param('name')

//=>"tobi"
