德龙 用户代理解析器。 用法示例： Drogon parser = new Drogon (); Iterator< String> iterator = parser . getProductList(useragentString) . iterator(); while (iterator . hasNext()){ System . out . println( " Product = " + iterator . next()); } 样本输出： useragentString = "curl/7.22.0 (x86_64-pc-linux-gnu) libcurl/7.22.0 OpenSSL/1.0.1 zlib/1.2.3.4 libidn/1.23 librtmp/2.3" Product = curl Product = libcurl
