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);
    
    // ...
});
