如何在 Node.js/Express 中进行重定向 (301)? [英] How to make a redirect (301) in Node.js / Express?

问题描述

我有一个静态网站，我在 Dokku 中部署了一个简单的单页面布局.我需要从 www 到非 www 以及从 *.website1.com 到 website2.com 进行重定向 (301)，但我不知道如何.我试图在 npm 中使用 express-force-domain 但它使我的 URL 变得疯狂并且有一些重定向循环，我正在尝试我在网上找到的其他方法但没有成功.

I have a static site, a simple single page layout that I deploy in Dokku. I need to make a redirect (301) from www to non www and from *.website1.com to website2.com, but I don't know how. I was trying to use express-force-domain in npm but it makes my URL's crazy and having some redirect loops, I was trying other methods that I find on the web but none succeeds.

我的 server.js 是:

my server.js is:

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

app.set('port', (process.env.PORT || 80))
app.use(express.static(__dirname + '/public'))

app.get('/', function(request, response) {
  response.send('Hello World!')
})

app.listen(app.get('port'), function() {
  console.log("Node app is running at localhost:" + app.get('port'))
})

这是有效的版本，但没有重定向.

That is the version that works, but without redirects.

推荐答案

res.redirect(301, 'http://yourotherdomain.com' + req.path)

请参阅Express 文档.
