1. 获取 Get请求 中url的参数：
const urlib = require("url");
// http:///www.web.com/Login?name=111&pass=222
router.get('/Login', function(req, res, next) {
var myObj = urlib.parse(req.url,true);
var name = myObj.query.name;
var pass = myObj.query.pass;
console.log('name = ' + name + ', pass = ' + pass);
// ...
});2. 获取 Post请求 的参数：
// http:///www.web.com/Login
router.post('/Login', function(req, res, next) {
var name = req.body.name;
var pass = req.body.pass;
console.log('name = ' + name + ', pass = ' + pass);
// ...
});
