如何将浏览器的网址重定向到 Nodejs 的其他网页？

For those who (unlike OP) are using the express lib:

http.get('*',function(req,res){
res.redirect('http://exmple.com'+req.url)
})

To effect a redirect, you send a redirect status (301 for permanent redirect, 302 for a "this currently lives on ..." redirect, and 307 for an intentional temporary redirect):

response.writeHead(301, {
Location: `http://whateverhostthiswillbe:8675/${newRoom}`
}).end();

OP: "I would love if there were a way to do it where I didn't have to know the host address..."

response.writeHead(301, {
Location: "http" + (request.socket.encrypted ? "s" : "") + "://" +
request.headers.host + newRoom
});
response.end();

You can use res.render() or res.redirect() method to redirect to another page using node.js express

Eg:

var bodyParser = require('body-parser');
var express = require('express');
var navigator = require('web-midi-api');
var app = express();


app.use(express.static(__dirname + '/'));
app.use(bodyParser.urlencoded({extend:true}));
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');
app.set('views', __dirname);


app.get('/', function(req, res){
res.render("index");
});


//This reponds a post request for the login page
app.post('/login', function (req, res) {
console.log("Got a POST request for the login");
var data = {
"email": req.body.email,
"password": req.body.password
};


console.log(data);


//Data insertion code
var MongoClient = require('mongodb').MongoClient;
var url = "mongodb://localhost:27017/";


MongoClient.connect(url, function(err, db) {
if (err) throw err;
var dbo = db.db("college");
var query = { email: data.email };
dbo.collection("user").find(query).toArray(function(err, result) {
if (err) throw err;
console.log(result);
if(result[0].password == data.password)




res.redirect('dashboard.html');
else




res.redirect('login-error.html');
db.close();
});
});


});




// This responds a POST request for the add user
app.post('/insert', function (req, res) {
console.log("Got a POST request for the add user");


var data = {
"first_name" : req.body.firstName,
"second_name" : req.body.secondName,
"organization" : req.body.organization,
"email": req.body.email,
"mobile" : req.body.mobile,
};


console.log(data);


**res.render('success.html',{email:data.email,password:data.password});**


});




//make sure that Service Workers are supported.
if (navigator.serviceWorker) {
navigator.serviceWorker.register('service-worker.js', {scope: '/'})
.then(function (registration) {
console.log(registration);
})
.catch(function (e) {
console.error(e);
})
} else {
console.log('Service Worker is not supported in this browser.');
}




// TODO add service worker code here
if ('serviceWorker' in navigator) {
navigator.serviceWorker
.register('service-worker.js')
.then(function() { console.log('Service Worker Registered'); });
}


var server = app.listen(63342, function () {


var host = server.address().host;
var port = server.address().port;


console.log("Example app listening at http://localhost:%s", port)
});

Here in the login section, If the email and password matches in the database then the site is directed to dashbaord.html otherwise we will show page-error.html using res.redirect() method. Also you can use res.render() to render a page in node.js

In Express you can use

res.redirect('http://example.com');

to redirect user from server.

To include a status code 301 or 302 it can be used

res.redirect(301, 'http://example.com');

If you are using Express, the cleanest complete answer is this

const express = require('express')
const app     = express()


app.get('*', (req, res) => {
// REDIRECT goes here
res.redirect('https://www.YOUR_URL.com/')
})


app.set('port', (process.env.PORT || 3000))
const server = app.listen(app.get('port'), () => {})
