Determine if the HTTP request originated from the mobile phone, or if there is a computer-initiated

In some cases, we need to determine whether the HTTP request is from the phone or the computer side, the key is to obtain user-agent information, screening and judgment can be.

The core classes are as follows:

public static Boolean  IsMobileDevice (String requestheader) {        /**         * android: All Android devices         * Mac OS: iphone ipad         * Windows Phone:nokia such as Windows system phone         */        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;

　　

Get the HTTP header information in the controller as follows:

     String Requestheader = Request.getheader ("user-agent");        if (Judgerequestdeviceutil.ismobiledevice (Requestheader)) {            logger.debug ("Use mobile browser");        } else{            logger.debug ("Use Web browser");        }

　　

functionis_mobile_visit () {//If you have http_x_wap_profile, it must be a mobile device .    if(isset($_server[' Http_x_wap_profile ']))    {        return true; }    //if the VIA message contains a WAP, it must be a mobile device, and some service providers block that information    if(isset($_server[' Http_via ']))    {        //not found for flase, otherwise true        return Stristr($_server[' Http_via '], "WAP")?true:false; }    //brain Residue method, determine the mobile phone to send the client logo, compatibility needs to be improved    if(isset($_server[' Http_user_agent ']))    {        $clientkeywords=Array(' Nokia ', ' Sony ', ' Ericsson ', ' mot ', ' Samsung ', ' HTC ', ' SGH ', ' lg ', ' sharp ', ' sie-', ' Philips ' , ' Panasonic ', ' Alcatel ', ' Lenovo ', ' iphone ', '                ipod ', ' blackberry ', ' Meizu ', ' Android ', ' NetFront ',                ' Symbian ', ' UCWeb ', ' windowsce ', ' palm ', ' Operamini ', ' Operamobi ', ' Openwave ', ' nexusone ', ' CLDC ', ' mid P ', ' wap ', ' mobile '        ); //find keywords for your phone's browser from Http_user_agent        if(Preg_match("/(" .implode(' | ',$clientkeywords) .
