HttpServletRequest獲取瀏覽器、服務端和客戶端信息

　　如何通過HttpServletRequest來獲取到上面的屬性呢？

1、引入開源工具

<!-- https://mvnrepository.com/artifact/eu.bitwalker/UserAgentUtils -->
<dependency>
    <groupId>eu.bitwalker</groupId>
    <artifactId>UserAgentUtils</artifactId>
    <version>1.21</version>
</dependency>

2、在controller中使用

UserAgent userAgent = UserAgent.parseUserAgentString(request.getHeader("User-Agent"));
Browser browser = userAgent.getBrowser();
OperatingSystem operatingSystem = userAgent.getOperatingSystem();
Version browserVersion = userAgent.getBrowserVersion();
log.info(browser.getName());
log.info(operatingSystem.getName());
log.info(browserVersion.getVersion());

3、運行結果

4、request的服務端和客戶端詳細信息

request.getLocalAddr();//獲取本地IP，即服務器IP
request.getLocalName();//獲取本地名稱，即服務器名稱
request.getLocalPort();//獲取本地端口號，即Tomcat端口號
request.getLocale();//用戶的語言環境
request.getContextPath();//context路徑
request.getMethod();//GET還是POST
request.getProtocol();//協議，http協議
request.getQueryString();//查詢字符串
request.getRemoteAddr();//遠程IP，即客戶端IP
request.getRemotePort();//遠程端口，即客戶端端口
request.getRemoteUser();//遠程用戶
request.getRequestedSessionId();//客戶端的Session的ID
request.getRequestURI();//用戶請求的URL
request.getScheme();//協議頭，例如http
request.getServerName();//服務器名稱
request.getServerPort();//服務器端口
request.getServletPath();//Servlet路徑
