Java获取浏览器信息、IP地址、操作系统信息

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 Gecko

**Chrome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/537.36

### 一、第一种方式 ###

使用工具类获取信息，添加maven依赖：

<dependency>
        <groupId>eu.bitwalker</groupId>
        <artifactId>UserAgentUtils</artifactId>
        <version>1.21</version>
    </dependency>

**1、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);
        }

**2、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();
        }

**3、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;
            }
        }

获得信息如下：![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3R5cDE4MDU_size_16_color_FFFFFF_t_70][]

### 二、第二种方式 ###

**1、获取浏览器名称（**获取不到IE的信息**）**

public static String getBrowserName(HttpServletRequest request) {
            String browserName = "";
            String userAgent = request.getHeader("User-Agent").toUpperCase();
            if (userAgent == null || userAgent.equals("")) {
                return "";
            }
            if (userAgent.indexOf("MSIE") > 0) {
                browserName = "IE";
            } else if (userAgent.indexOf("FIREFOX") > 0) {
                browserName = "Firefox";
            } else if (userAgent.indexOf("CHROME") > 0) {
                browserName = "Chrome";
            } else if (userAgent.indexOf("SAFARI") > 0) {
                browserName = "Safari";
            } else if (userAgent.indexOf("CAMINO") > 0) {
                browserName = "Camino";
            } else if (userAgent.indexOf("KONQUEROR") > 0) {
                browserName = "Konqueror";
            } else if (userAgent.indexOf("EDGE") > 0) {
                browserName = "Microsoft Edge";
            }
            return browserName;
        }

** 2、获取操作系统名称**

public static String getOSname(HttpServletRequest request) {
            String osName = "";
            String userAgent = request.getHeader("User-Agent").toUpperCase();
            if (userAgent.contains("WINDOWS")) {
                if (userAgent.contains("WINDOWS NT 10.0")) {
                    osName = "Windows 10";
                } else if (userAgent.contains("WINDOWS NT 6.2")) {
                    osName = "Windows 8";
                } else if (userAgent.contains("WINDOWS NT 6.1")) {
                    osName = "Windows 7";
                } else if (userAgent.contains("WINDOWS NT 6.0")) {
                    osName = "Windows Vista";
                } else if (userAgent.contains("WINDOWS NT 5.2")) {
                    osName = "Windows XP";
                } else if (userAgent.contains("WINDOWS NT 5.1")) {
                    osName = "Windows XP";
                } else if (userAgent.contains("WINDOWS NT 5.01")) {
                    osName = "Windows 2000";
                } else if (userAgent.contains("WINDOWS NT 5.0")) {
                    osName = "Windows 2000";
                } else if (userAgent.contains("WINDOWS NT 4.0")) {
                    osName = "Windows NT 4.0";
                } else if (userAgent.contains("WINDOWS 98; WIN 9X 4.90")) {
                    osName = "Windows ME";
                } else if (userAgent.contains("WINDOWS 98")) {
                    osName = "Windows 98";
                } else if (userAgent.contains("WINDOWS 95")) {
                    osName = "Windows 95";
                } else if (userAgent.contains("WINDOWS CE")) {
                    osName = "Windows CE";
                }
            } else if (userAgent.contains("MAC")){
                osName = "Mac";
            } else if (userAgent.contains("UNIX")){
                osName = "UNIX";
            } else if (userAgent.contains("LINUX")){
                osName = "Linux";
            } else if (userAgent.contains("SUNOS")){
                osName = "SunOS";
            }
            return osName;
        }

获取IP地址和第一种方式是一样的，获取后的效果是这样的：

第二种显然无法满足需求，推荐使用第一种工具类的方式获取。
