Nodejs路由之间的数据传递

实例是模拟登录页面提交表单，然后根据信息判断是否登录成功

login.js

var express =require(‘express‘);
var router =express.Router();

router.get(‘/‘,function(req,res,next){
    res.render("login.jade");
});

module.exports = router;

login.jade

doctype html
html
    head
         meta(http-equiv="Content-Type",content="text/html; charset=utf-8")
    title 添加数据页
    body
        h1 请填写你要发送的信息
        form(action="/loginmsg",method="post")
         input(name="msg",type="text",id="msg")
         input(name="submit",type="submit")

loginmsg.js

var express =require(‘express‘);
var router =express.Router();

router.post(‘/‘,function(req,res,next){
var msg = req.body.msg;
    if(msg){
 res.render("loginmsg.jade",{msg:msg});
     }
});

module.exports = router;

loginmsg.jade

doctype html
html
 head
  title 主页
 body
    div 你发送的信息为：#{msg}

app.js

var express = require(‘express‘);
var path = require(‘path‘);
var app = express();
var bodyParser = require(‘body-parser‘);
var login = require(‘./routes/login‘);
var loginmsg = require(‘./routes/loginmsg‘);

//模板引擎设置
app.set(‘views‘, path.join(__dirname, ‘views‘));
app.set(‘view engine‘, ‘jade‘);
app.use(express.static(‘public‘));

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
    extended: true
})); 

//设置路由
app.use(‘/‘,login);
app.use(‘/loginmsg‘,loginmsg);

app.listen(3000);
console.log("启动端口:3000");
