                return  "ios手机端";
            }else {
                return  "电脑端";
    
            }
        }
    
        /**

         * @param userAgent
         * @return
         */
        public static String getAskType(String userAgent) {
            userAgent=userAgent.toLowerCase();
            if (userAgent.contains("windows phone")
                    ||
                    userAgent.contains("android")
                    ||
                    userAgent.contains("iphone")
                    ||
                    userAgent.contains("ipad") //暂且把ipad也归为苹果设备
            ){
                return  "mobile";
            }else {
                return  "pc";
    
            }
        }
    
    }

接口测试&使用方式：

就是从HttpServletRequest request 的头里拿出 user-agent 这个key的值做识别处理。

@GetMapping("doSomeTest")
        public void doSomeTest(HttpServletRequest request){
            
            
            String userAgent  = request.getHeader("user-agent");
            
            
            String requestDevice = getRequestDevice(userAgent);
            System.out.println(requestDevice);
    
            
            String askType = getAskType(userAgent);
            System.out.println(askType);
    
        }
