我们可以通过userAgent来判断,比如检测某些关键字,例如:AppleWebKit*****Mobile或AppleWebKit,需要注意的是有些浏览器的userAgent中并不包含AppleWebKit关键字,可能会是Linux,UCBrowser等等。
1. Javascript

<?php /** * 判断是否是通过手机访问 * @return bool 是否是移动设备 */ public function isMobile() { //判断手机发送的客户端标志 if (isset( $_SERVER [ ‘HTTP_USER_AGENT‘ ])) { $userAgent = strtolower ( $_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‘ , ‘opera mobi‘ , ‘openwave‘ , ‘nexusone‘ , ‘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 ).

下面的jsp代码简单判断浏览器类型,如果是iphone或者android就跳转到手机版本网页:

<% String ua = request.getHeader( "User-Agent" ) ; if (ua != null ) { if (ua.indexOf( "iPhone" ) >- 1 || ua.indexOf( "iPad" ) >- 1 || (ua.indexOf( "ndroid" ) >- 1 && ua.indexOf( "WebKit" ) >- 1 )) { return ; } } %> |
下面是.NET代码(C#)
在.NET下,其中一个方法是利用HttpBrowserCapabilities,代码如下:

System.Web.HttpBrowserCapabilities browser = Request.Browser; string s = "Browser Capabilities\n" + "Type = " + browser.Type + "\n" + "Name = " + browser.Browser + "\n" + "Version = " + browser.Version + "\n" + "Major Version = " + browser.MajorVersion + "\n" + "Minor Version = " + browser.MinorVersion + "\n" + "Platform = " + browser.Platform + "\n" + "Is Beta = " + browser.Beta + "\n" + "Is Crawler = " + browser.Crawler + "\n" + "Is AOL = " + browser.AOL + "\n" + "Is Win16 = " + browser.Win16 + "\n" + "Is Win32 = " + browser.Win32 + "\n" + "Supports Frames = " + browser.Frames + "\n" + "Supports Tables = " + browser.Tables + "\n" + "Supports Cookies = " + browser.Cookies + "\n" + "Supports VBScript = " + browser.VBScript + "\n" + "Supports JavaScript = " + browser.EcmaScriptVersion.ToString() + "\n" + "Supports Java Applets = " + browser.JavaApplets + "\n" + "Supports ActiveX Controls = " + browser.ActiveXControls + "\n" + "Supports JavaScript Version = " + browser[ "JavaScriptVersion" ] + "\n" ; |
在web.config中需要在filter中进行匹配

<system.web> <browserCaps> <use var= "HTTP_USER_AGENT" /> <filter> < case match= "Windows NT 6.1" > platform=Windows7 </ case > </filter> </browserCaps> </system.web> |

///<summary> /// 根据 Agent 判断是否是智能手机 ///</summary> ///<returns></returns> public static bool CheckAgent() { bool flag = false ; string agent = HttpContext.Current.Request.UserAgent; string [] keywords = { "Android" , "iPhone" , "iPod" , "iPad" , "Windows Phone" , "MQQBrowser" }; //排除 Windows 桌面系统 if (!agent.Contains( "Windows NT" ) || (agent.Contains( "Windows NT" ) && agent.Contains( "compatible; MSIE 9.0;" ))) { //排除 苹果桌面系统 if (!agent.Contains( "Windows NT" ) && !agent.Contains( "Macintosh" )) { foreach ( string item in keywords) { if (agent.Contains(item)) { flag = true ; break ; } } } } return flag; } |
代码解释:
1. !agent.Contains("Windows NT") && !agent.Contains("Macintosh") 排除Window 桌面系统 和 苹果桌面系统
2. "Android", "iPhone", "iPod", "iPad", "Windows Phone", "MQQBrowser" 这些是判断智能设备Agent中的关键词
3. MQQBrowser 为 QQ 手机浏览器,QQ 手机的Agent 比较特殊,所以单独判断
各移动浏览器的http user-agent:
一、微信的http user-agent(关键词MicroMessenger)
1. Iphone(苹果)平台微信的ucweb的useragent:
Mozilla/5.0 (iPhone; CPU iPhone OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Mobile/9B176 MicroMessenger/4.3.2
2. Android(安卓)平台微信的ucweb的useragent:1
Mozilla/5.0 (Linux; U; Android 2.3.6; zh-cn; GT-S5660 Build/GINGERBREAD) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1 MicroMessenger/4.5.255
二、UC浏览器的http user-agent(关键词UCWEB)
1. android平台:
android平台ucweb急速模式开启下ucweb浏览器useragent:
UCWEB/2.0 (Linux; U; Adr 2.3; zh-CN; MI-ONEPlus) U2/1.0.0 UCBrowser/8.6.0.199 U2/1.0.0 Mobile
android平台ucweb急速模式关闭状态下的http_user_agent:
Mozilla/5.0 (Linux; U; Android 2.3; zh-CN; MI-ONEPlus) AppleWebKit/534.13 (KHTML, like Gecko) UCBrowser/8.6.0.199 U3/0.8.0 Mobile Safari/534.13
2. iPhone 平台
iPhone 平台极速模式开启状态下ucweb浏览器useragent:
UCWEB/2.0 (iOS; U; iPh OS 4_3_2; zh-CN; iPh4) U2/1.0.0 UCBrowser/8.6.0.199 U2/1.0.0 Mobile
iPhone 平台极速模式关闭状态下 UA 示例如下:(OBUA 为自带浏览器 UA)\
OBUA UCBrowser/8.6.0.199 Mobile
3. iPad 平台
ipad平台下ucweb浏览器useragent:
Mozilla/5.0 (iPad; U; CPU OS 6_0 like Mac OS X; zh-CN; iPad2) AppleWebKit/534.13 (KHTML, like Gecko) UCBrowser/8.6.0.199 U3/0.8.0 Safari/534.13
4. windows Phone平台
WP平台下ucweb浏览器useragent:
WP平台极速模式开启状态下:(以 Nokia 900 为例)
UCWEB/2.0 (Windows; U; wds7.10; zh-CN; Nokia 900) U2/1.0.0 UCBrowser/8.6.0.199 U2/1.0.0 Mobile
5. 诺基亚平台
诺基亚手机Symbian&Java平台ucweb浏览器useragen:
Nokia 5800 XpressMusic/UCWEB8.9.0.253/50/999
安卓QQ浏览器HD版检测的结果是:mac, Safari,这个很是变态,自己看着处理吧
3个检测浏览器User-Agent信息的网站
三、一些特别的浏览器
QQ浏览器(android)
MQQBrowser/3.6/Adr (Linux; U; 4.0.3; zh-cn; HUAWEI U8818 Build/U8818V100R001C17B926;480*800)
魅族UC浏览器(android)
JUC (Linux; U; 2.3.5; zh-cn; MEIZU MX; 640*960) UCWEB8.5.1.179/145/33232
UC浏览器(iphone)
IUC(U;iOS 5.1;Zh-cn;320*480;)/UCWEB8.8.0.212/42/997
Opera mobile(android)
Opera/9.80 (Android 4.0.3; Linux; Opera Mobi/ADR-1210241554) Presto/2.11.355 Version/12.10
Opera mini(iphone)
Opera/9.80 (iPhone; Opera Mini/7.0.5/28.2690; U; zh) Presto/2.8.119 Version/11.10
三个在线网站,通过手机浏览器就可以在线检测
1. http://whatsmyuseragent.com/
2. http://whatsmyua.com/
3. http://www.useragentstring.com/
