如何检测用于访问我网站的浏览器？

request = requests.get("https://your-website.com")
ua = request.headers.get("User-Agent")
print(ua)

navigator.userAgent

const http = require('http');
const request = http.request({
    method: 'GET',
    headers: {'user-agent': 'Mozilla/5.0'},
    url: 'https://your-website.com'
}, (res) => {
    console.log(res.headers.get('user-agent'));
}).on('error', (error) => {
    console.log('Error: ' + error.message);
});
