<meta property="og:title" content="Your Title" />
<meta property="og:description" content="Your Description" />
<meta property="og:image" content="URL to your image" />
<meta property="og:url" content="URL to your page" />
<meta property="og:type" content="website" />

document.addEventListener('DOMContentLoaded', function() {
    const metaTitle = document.createElement('meta');
    metaTitle.property = 'og:title';
    metaTitle.content = 'Dynamic Title';
    document.head.appendChild(metaTitle);

    // 同样的方式添加其他OG标签
});

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

app.use((req, res, next) => {
    res.header('Access-Control-Allow-Origin', '*');
    res.header('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept');
    next();
});

app.get('/', (req, res) => {
    res.send('Hello World!');
});

app.listen(3000, () => console.log('Server running on port 3000'));

Header set Access-Control-Allow-Origin "*"
