Nodejs Server Hostname
提问by Craig Myles
Ok, so it seems pretty easy in Node.js to get the hostname of the request being made to my server:
好的，所以在 Node.js 中获取向我的服务器发出的请求的主机名似乎很容易：
app.get('/', function(req,res){
console.log(req.headers.host);
});
Is there an easy way to determine the hostname of my actual http server? For example, my server is running at the address http://localhost:3000- can I programatically determine this address? I am using expressjs.
有没有一种简单的方法来确定我的实际 http 服务器的主机名？例如，我的服务器正在该地址运行http://localhost:3000- 我可以通过编程方式确定该地址吗？我正在使用 expressjs。

Yes you can using the;
是的，您可以使用；
var express = require('express'),
app = express(),
server = require('http').createServer(app);
server.listen(3000, function(err) {
console.log(err, server.address());
});
should print
应该打印
{ address: '0.0.0.0', family: 'IPv4', port: 3000 }
you can also retreive the hostname for the os by the following;
您还可以通过以下方式检索操作系统的主机名；
require('os').hostname();
