现在通过webStorm生成express项目，express版本是4.2.0，其中的路由使用类似如下的方式控制.
求解如何修改能达到login处理post请求。
app.js
var express = require('express');
var path = require('path');
var favicon = require('static-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var routes = require('./routes/index');
var users = require('./routes/users');
var login = require('./routes/login');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(favicon());
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', routes);
app.use('/users', users);
app.use('/login', login);
想让我的login路由来处理post请求
login.js
var express = require('express');
var router = express.Router();
/* GET users listing. */
router.get('/', function(req, res) {
var username = req.param('username', null);
var password = req.param('password', null);
console.log("username:" + username + " password:" + password);
res.send('login');
});
module.exports = router;
求解如何修改能达到login处理post请求。
