推荐答案

使用用户代理。根据方便和惯例，与服务器的每个连接都带有此标头。无法保证浏览器是真实的（例如spambot将自己报告为Chrome）。您可以按如下方式获取用户代理：

Use the user-agent. Every connection to your server carries this header, by convenience and convention. There is no guarantee that a browser will be truthful(such as a spambot reporting itself as Chrome). You can get the user-agent as follows:

request.getHeader("User-Agent");

然后再次检查已知的用户代理字符串和模板。

and then check again known user-agent strings and templates.
