在Node.js中获取客户端主机名 [英] Getting client hostname in Node.js

问题描述

是否可以在Node.js中获取主机名？

is it possible to get hostname in Node.js?

这就是我获取客户端IP的方式：

var ip = request.header('x-forwarded-for');

那么，我如何获得客户的主机名？

var hostname = request.header('???');

感谢您的回复！

推荐答案

我认为你能做到的唯一方法就是这样：

I think the only way you can do it is like this:

<form method="post" action="/gethostname">
    <label for="hostname">What is your hostname?</label>
    <input type="text" name="hostname" id="hostname">
</form>

但我建议你真的不需要它，它不像你可以做任何有用的事情信息。如果你只是想要一个字符串来识别用户的机器，那么你可以做些什么。

But I would suggest you don't really need it, it's not like you can do anything useful with the information. If you just want a string to identify with the user's machine then you can make something up.

如果你真正关注的是FQDN那么我会建议它仍然是对你没那么有用，但为此你需要反向DNS查找。如果您使用VPS或类似设备，您可以配置您的盒子为您执行此操作，但请注意，它可能需要几秒钟，因此在响应中执行此操作并不是一个好主意。另请注意，在大多数情况下，您不会获得用户机器的FQDN，而是路由器的FQDN。

If what you're really after is the FQDN then I would suggest it's still not really that useful to you, but for that you need Reverse DNS lookup. If you're on a VPS or similar you can probably configure your box to do this for you, but note that it'll likely take a few seconds so it's not a good idea to do it as part of a response. Also note, you'll not be getting the user's machine's FQDN in most cases but that of their router.
