域名怎么跳转代码

# 使用 .htaccess 文件
Redirect 301 /oldpage.html http://www.example.com/newpage.html

# 或者在 httpd.conf 文件中
RewriteEngine On
RewriteRule ^oldpage.html$ http://www.example.com/newpage.html [R=301,L]

server {
    listen 80;
    server_name www.example.com;

    location /oldpage.html {
        return 301 http://www.example.com/newpage.html;
    }
}

<?php
header('Location: http://www.example.com/newpage.html', true, 301);
exit();
?>

from flask import Flask, redirect

app = Flask(__name__)

@app.route('/oldpage')
def oldpage():
    return redirect('http://www.example.com/newpage.html', code=301)

if __name__ == '__main__':
    app.run()

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

app.get('/oldpage', (req, res) => {
    res.redirect(301, 'http://www.example.com/newpage.html');
});

app.listen(3000);
