从用户重定向到我的网站的位置获取 url

Question

所以，几天前我在 github 上看到了见解，他们给出了流量来源，我如何使用 node.js (express) 做到这一点？

Answer 1

I believe you're looking for req.hostname . Have you tried it? It returns the first X-Forwarded-Host .

Example (from previously linked documentation):

// Host: "example.com:3000"
console.dir(req.hostname)
// => 'example.com'

Answer 2

You can get it with:

document.referrer

Which returns:

the URI of the page that linked to this page. _MDN
