如何從不同的中間件使用快速響應對象獲取數據

Question

可能是這個愚蠢的問題.. :)有些可以幫助我從響應對象中獲取數據。基本上我想驗證了我的響應數據快遞

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

app.use('/', function(req, res, next){ 
    console.log('entry point'); 
    res.json({name:"somename",age: 29}); 
    next() 
}); 

var middleware = function (req, res, next) { 

console.log('LOGGED'); 

res.end = function (req, res , next) { 
    var data = res.data; 
    //do some validation logic here 
    next() 
}}; 
app.use(middleware); 

var port = process.env.PORT || 10010; 
app.listen(port);

使用其他middlware您可以通過以下方式

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

var middleware = function (req, res, next) { 
    //function to be called on finish and close event 
    function afterResponse() { 
     res.removeListener('finish', afterRequest); 
     //res.removeListener('close', afterRequest); 

     //You can do some validation logic here. 
    } 


    res.on('finish', afterResponse); 
    //res.on('close', afterResponse); 
}}; 

//Using the middleware before all the request 
app.use(middleware); 

app.use('/', function(req, res, next){ 
    console.log('entry point'); 
    res.json({name:"somename",age: 29}); 
}); 

var port = process.env.PORT || 10010; 
app.listen(port); 

讓我知道，如果您有任何疑問，做到這一點。
