Acknowledging that the user agent is unsafe. Still, in the lack of other ways, you should parse a user-agent header, which in fact is not as easy, as the number of combinations is overwhelming. Unless you want to roll your own, I would suggest
承认用户代理是不安全的。尽管如此，在缺乏其他方法的情况下，您应该解析用户代理标头，这实际上并不容易，因为组合的数量太多了。除非你想自己动手，否则我建议

the usage is quite straightforward
用法很简单
UserAgent userAgent = UserAgent.parseUserAgentString(request.getHeader("User-Agent"));
System.out.println(userAgent.getBrowser().getName() + " " + userAgent.getBrowserVersion());
