1 需求 业务需求需要记录用户登录时的信息：浏览器信息、IP地址、操作系统信息等，从网上查找了很多帖子，实现方式有两种，一种纯编码判断，一种是使用UserAgentUtils工具类。 注：经测试第一种方式获取浏览器名称时获取不到IE的信息，第二种是可以的。 IE11请求的User-Agent为： Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like GeckoChrome请求的User-Agent为： Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.362 实现使用工具类获取信息，添加maven依赖： eu.bitwalker UserAgentUtils 1.21获取浏览器名称及版本 public static String browserName(HttpServletRequest request){ String userAgent = request.getHeader("User-Agent"); UserAgent ua = UserAgent.parseUserAgentString(userAgent); Browser browser = ua.getBrowser(); return browser.getName() + "-" + browser.getVersion(userAgent); }获取操作系统名称 public static String osName(HttpServletRequest request){ String userAgent = request.getHeader("User-Agent"); UserAgent ua = UserAgent.parseUserAgentString(userAgent); OperatingSystem os = ua.getOperatingSystem(); return os.getName(); }获取IP地址 public static String getIpAddress(HttpServletRequest request) { String ip = request.getHeader("X-Forwarded-For"); if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("Proxy-Client-IP"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("WL-Proxy-Client-IP"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("HTTP_X_FORWARDED_FOR"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("HTTP_X_FORWARDED"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("HTTP_X_CLUSTER_CLIENT_IP"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("HTTP_CLIENT_IP"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("HTTP_FORWARDED_FOR"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("HTTP_FORWARDED"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("HTTP_VIA"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("REMOTE_ADDR"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getRemoteAddr(); } if (ip.contains(",")) { return ip.split(",")[0]; } else { return ip; } } |
