form.ejs

get_post.js

1. post的数据要用req.on('data',function(){})接收
2. req.method,判断请求是get还是post

var fs = require('fs');var path = require('path');var url = require('url');var ejs = require('ejs');var http = require('http');http.createServer(function(req,res){    res.writeHead(200,{"Content-Type":"text/html;charset='utf-8'"});    var method = req.method.toLowerCase();    var pathname = url.parse(req.url,true).pathname;    if(pathname == '/login'){        ejs.renderFile('views/form.ejs',{},function(err,data){            res.end(data)        })    }else if(pathname == '/dologin' && method == 'get'){        console.log(url.parse(req.url,true).query);        res.end('dologin');    }else if(pathname == '/dologin' && method == 'post'){        var postStr = '';        req.on('data',function(chunk){            postStr += chunk;        })        req.on('end',function(err,chunk){            fs.appendFile('login.txt',postStr+'\n',function(err){                if(err){                    console.log(err);                    return;                }                console.log('写入数据成功');            })            res.end("")        })    }else{        ejs.renderFile('views/index.ejs',{},function(err,data){            res.end(data);        })    }}).listen(8000)
