使用UADetector检测机器人
问题描述：
我正在测试Java用户代理检测器API http://uadetector.sourceforge.net 。根据项目主页，API可以检测机器人。但是查看文档并使用API我无法找到机器人的参考。
I am testing Java user-agent detector API http://uadetector.sourceforge.net. According to the project home page the API can detect robots. But looking at the docs and playing around with the API I can't find reference to Robots.
任何人都可以指引我走向正确的方向吗？
Can anyone direct me to the right direction?
答
你可以这样做：
UserAgentStringParser parser = UADetectorServiceFactory.getOnlineUpdatingParser();
ReadableUserAgent agent = parser.parse(request.getHeader("User-Agent"));
UserAgentType type = agent.getUserAgentType(); // this can be ROBOT, BROWSER, etc.
