节点localhost没有返回日期

Question

我有以下index.js文件：

var express = require('express');
var app = express();

app.use('/',(req,res) => {

console.log(req.get('Date'));
console.log(req.get('User-Agent'));
console.log(req.url);

var name = req.query.name;
res.status(200).type('html');

res.write('Hello World! <br>');
if (name) {
   res.write('Hi, ' + name + " it's nice to see you.");
}else{
   res.write('Welcome, guest!');
}

res.end();
});

app.listen(3001, () => {
console.log('Listening on port 3001');

});

为什么日期未定义？

Answer 1

因为您使用的浏览器未在标题中发送日期...

您可以使用本地服务器日期....
