如何限制仅从单个url访问我的angular站点？

server {
    listen 80;
    server_name yourdomain.com;

    location / {
        allow 192.168.1.1;  # 允许的IP地址
        deny all;           # 拒绝其他所有IP
        proxy_pass http://localhost:4200;  # 假设Angular应用运行在4200端口
    }
}

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_URI} !^/allowed-url$
    RewriteRule .* - [F]
</IfModule>

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

app.use((req, res, next) => {
    if (req.headers['x-forwarded-for'] === 'allowed-ip') {
        next();
    } else {
        res.status(403).send('Forbidden');
    }
});

app.use(express.static('dist'));  // 假设Angular应用构建在dist目录

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

server {
    listen 80;
    server_name yourdomain.com;

    location / {
        auth_basic "Restricted Area";
        auth_basic_user_file /etc/nginx/.htpasswd;
        proxy_pass http://localhost:4200;
    }
}
