var url=require(‘url’); var urlObj=url.parse(req.url,true);
var pathName=urlObj.pathname; var newMess=urlObj.query;

掌握重定向方式

res.stateCode=“302”; res.setHeader(‘Location’,’/’); res.end();

var fs=require('fs');
var http=require('http');
var template=require('art-template');
var url=require('url');

];
