首先收集了部分客户端请求头部信息如下

iPhone微信:

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',

        );
        // 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;
