判断http 请求来自于手机还是PC

首先收集了部分客户端请求头部信息如下

iPhone微信：
User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 8_1_2 like Mac OS X) AppleWebKit/600.1.4 (KHTML, like Gecko) Mobile/12B440 MicroMessenger/6.2.4 NetType/WIFI Language/en

iPhone—safari
User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 8_1_2 like Mac OS X) AppleWebKit/600.1.4 (KHTML, like Gecko) Version/8.0 Mobile/12B440 Safari/600.1.4

 

Android-Chrome

User-Agent:Mozilla/5.0 (Linux; Android 4.4.4; HTC D820u Build/KTU84P) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.89 Mobile Safari/537.36

PC-Chrome
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.80 Safari/537.36

PC-Firefox
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.0

PC-IE
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko

 

我们需要判断Http请求是来自手机端还是电脑端，关键是取得User-Agent的信息，进行筛选判断即可。

public static boolean  isMobileDevice(String requestHeader){
        /**
         * android : 所有android设备
         * mac os : iphone ipad
         * windows phone:Nokia等windows系统的手机
         */
        String[] deviceArray = new String[]{"android","mac os","windows phone"};
        if(requestHeader == null)
            return false;
        requestHeader = requestHeader.toLowerCase();
        for(int i=0;i<deviceArray.length;i++){
            if(requestHeader.indexOf(deviceArray[i])>0){
                return true;
            }
        }
        return false;
}

在controller中获取http头信息如下：

    String requestHeader = request.getHeader("user-agent");
        if(JudgeRequestDeviceUtil.isMobileDevice(requestHeader)){
            logger.debug("使用手机浏览器");
        }else{
            logger.debug("使用web浏览器");
        }

 

php: 判断是不是微信客户端的请求

function is_in_wx(){
    $user_agent = $_SERVER[\'HTTP_USER_AGENT\'];
    return false!=strpos($user_agent, \'MicroMessenger\');
}

php: 判断是不是手机的请求 

function is_mobile_visit()
{
    // 如果有HTTP_X_WAP_PROFILE则一定是移动设备
    if (isset ($_SERVER[\'HTTP_X_WAP_PROFILE\']))
    {
        return true;
    }
    // 如果via信息含有wap则一定是移动设备,部分服务商会屏蔽该信息
    if (isset ($_SERVER[\'HTTP_VIA\']))
    {
        // 找不到为flase,否则为true
        return stristr($_SERVER[\'HTTP_VIA\'], "wap") ? true : false;
    }
    // 脑残法，判断手机发送的客户端标志,兼容性有待提高
    if (isset ($_SERVER[\'HTTP_USER_AGENT\']))
    {
        $clientkeywords = array (\'nokia\',
                \'sony\',
                \'ericsson\',

                \'cldc\',
                \'midp\',
                \'wap\',
                \'mobile\'
        );
        // 从HTTP_USER_AGENT中查找手机浏览器的关键字
        if (preg_match("/(" . implode(\'|\', $clientkeywords) . ")/i", strtolower($_SERVER[\'HTTP_USER_AGENT\'])))
        {
            return true;
        }
    }
    // 协议法，因为有可能不准确，放到最后判断
    if (isset ($_SERVER[\'HTTP_ACCEPT\']))
    {
        // 如果只支持wml并且不支持html那一定是移动设备
        // 如果支持wml和html但是wml在html之前则是移动设备
        if ((strpos($_SERVER[\'HTTP_ACCEPT\'], \'vnd.wap.wml\') !== false) && (strpos($_SERVER[\'HTTP_ACCEPT\'], \'text/html\') === false || (strpos($_SERVER[\'HTTP_ACCEPT\'], \'vnd.wap.wml\') < strpos($_SERVER[\'HTTP_ACCEPT\'], \'text/html\'))))
        {
            return true;
        }
    }
    return false;
