        userAgent=userAgent.toLowerCase();
        if (userAgent.contains("windows phone")
                ||
                userAgent.contains("android")
                ||
                userAgent.contains("iphone")
                ||
                userAgent.contains("ipad") //暫且把ipad也歸為蘋果裝置
        ){
            return  "mobile";
        }else {
            return  "pc";

        }
    }

}      

接口測試&使用方式：

就是從HttpServletRequest request 的頭裡拿出 user-agent 這個key的值做識别處理。

@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);

    }
