NodeJS學習第一季-路由規則

一、req.query 處理GET請求 ，獲取GET參數

//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"

二、req.body 處理POST請求，獲取POST參數

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

req.body.user.name

//=>"tobi"

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

req.body.name

//=>"tobi"

三、req.params 處理/xxx形式的GET/POST請求

//GET /user/tj

req.params.user

//=>"tj"

//GET /js/javascript/jquery.js

req.params[0]

//=>"javascript/jquery.js"

四、req.param() 處理GET/POST請求，但查找優先級由高到低爲 req.params-->req.body-->req.query

//?name=tobi

req.param('name')

//=>"tobi"

//POST name=tobi

req.param('name')

//=>"tobi"
