【Java 学习】服务端获取客户端浏览器、操作系统、设备类型等信息

1、服务端获取客户端信息

（1）常见问题

我在工作中遇到一个问题，需要在服务端判断用户的操作系统类型，然后选择系统的版本是Windows版还是Linux版。核心问题是怎么判断客户端的操作类型

（2）相关依赖

在Maven的官网找到我们所需要的依赖，引入项目中

<!-- 获取客户端信息 -->
<!-- https://mvnrepository.com/artifact/eu.bitwalker/UserAgentUtils -->
<dependency>
    <groupId>eu.bitwalker</groupId>
    <artifactId>UserAgentUtils</artifactId>
    <version>1.21</version>
</dependency>

（3）编写工具类

import eu.bitwalker.useragentutils.Browser;
import eu.bitwalker.useragentutils.OperatingSystem;
import eu.bitwalker.useragentutils.UserAgent;
import org.apache.commons.lang3.StringUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import javax.servlet.http.HttpServletRequest;

（4）核心控制层

我这里为了方便，创建的是 spring boot 项目，然后用内网穿透提供的访问，这样方便测试，使用Windows 和 Linux 判断

package cn.tellsea.systemtype.controller;

import cn.tellsea.systemtype.utils.UserAgentUtils;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.servlet.http.HttpServletRequest;

/**
 * @author Tellsea
 * @date 2020/10/27
 */
@Controller
public class TestController {
    
    

    @GetMapping("test")
    @ResponseBody
    public String test(HttpServletRequest request) {
    
    
        String userAgent = request.getHeader("user-agent");
        System.out.println("agent: " + userAgent);
        System.out.println("浏览器组：" + UserAgentUtils.getBorderGroup(userAgent));
        System.out.println("浏览器名字：" + UserAgentUtils.getBorderName(userAgent));
        System.out.println("浏览器类型" + UserAgentUtils.getBorderType(userAgent));
        System.out.println("浏览器生产商：" + UserAgentUtils.getBrowserManufacturer(userAgent));
        System.out.println("浏览器版本：" + UserAgentUtils.getBrowserVersion(userAgent));
        System.out.println("设备生产厂商:" + UserAgentUtils.getDeviceManufacturer(userAgent));
        System.out.println("设备类型:" + UserAgentUtils.getDeviceType(userAgent));
        System.out.println("设备操作系统：" + UserAgentUtils.getOs(userAgent));
        System.out.println("操作系统的名字：" + UserAgentUtils.getOsName(userAgent));
        System.out.println("操作系统的版本号：" + UserAgentUtils.getOsVersion(userAgent));
        System.out.println("操作系统浏览器的渲染引擎:" + UserAgentUtils.getBorderRenderingEngine(userAgent));
        String os = UserAgentUtils.getOs(userAgent);
        if (os.contains("Windows")) {
    
    
            System.out.println("是Windows");
        } else if (os.contains("Linux")) {
    
    
            System.out.println("是Linux");
        } else {
    
    
            System.out.println("无法匹配: {" + os + "}");
        }
        return "测试成功";
    }
}

如果是java 写的main方法，直接用浏览器查看请求信息时的userAgent测试即可
