var http = require('http')
var fs = require('fs')
var url = require('url')  // 引入url模块解析url地址，eg：127.0.0.1:8080/index.html?a=1&b=2 需要将?后的参数去掉

http.createServer(function(req, res){
  var pathObj = url.parse(req.url, true)
  console.log(pathObj)

  switch (pathObj.pathname) {  // 路由
    case '/getWeather':

      res.end(JSON.stringify(ret))
