如何使用userAgent检测移动设备

How to Use userAgent to detect mobile device

本文关键字：移动 检测 何使用 userAgent      更新时间：2023-09-26

有人能帮我吗。

我想检测设备，如Iphone，BB，andriod和浏览器应用他们的特定css，使其液化或调整到他们的分辨率。

当涉及到移动浏览器时，andriod和Iphone是否存在分辨率差异或css问题，因为我计划为这两个浏览器使用相同的css，因为我知道他们默认使用相同的浏览器safari。

以下是javascript中的一个示例：

var isMobile = navigator.userAgent.match(/(iPhone|iPod|iPad|Android|BlackBerry)/);
if (isMobile) {
   // User-Agent is IPhone, IPod, IPad, Android or BlackBerry
}

要检查特定的用户代理字符串，可以执行以下操作：

if (navigator.userAgent.match(/iPhone/)) {
   // The User-Agent is iPhone
}

尝试使用http://www.php.net/get_browser并检查CCD_ 1字段。当然，只有在php.ini中设置了browscap.ini的路径时，它才有帮助https://github.com/garetjax/phpbrowscap

<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0;  user-scalable=0;" />
<meta name="HandheldFriendly" content="true"/>
<meta name="MobileOptimized" content="320"/>
<meta http-equiv="cleartype" content="on" />

use this code on your website under <header> tag.

这是移动设备检测的代码。

 function isMobile() {
// Check the server headers to see if they're mobile friendly
if(isset($_SERVER["HTTP_X_WAP_PROFILE"])) {
    return true;
}
// If the http_accept header supports wap then it's a mobile too
if(preg_match("/wap'.|'.wap/i",$_SERVER["HTTP_ACCEPT"])) {
    return true;
}
// Still no luck? Let's have a look at the user agent on the browser. If it contains
// any of the following, it's probably a mobile device. Kappow!
if(isset($_SERVER["HTTP_USER_AGENT"])){
    $user_agents = array("midp", "j2me", "avantg", "docomo", "novarra", "palmos", "palmsource", "240x320", "opwv", "chtml", "pda", "windows' ce", "mmp'/", "blackberry", "mib'/", "symbian", "wireless", "nokia", "hand", "mobi", "phone", "cdm", "up'.b", "audio", "SIE'-", "SEC'-", "samsung", "HTC", "mot'-", "mitsu", "sagem", "sony", "alcatel", "lg", "erics", "vx", "NEC", "philips", "mmm", "xx", "panasonic", "sharp", "wap", "sch", "rover", "pocket", "benq", "java", "pt", "pg", "vox", "amoi", "bird", "compal", "kg", "voda", "sany", "kdd", "dbt", "sendo", "sgh", "gradi", "jb", "'d'd'di", "moto");
    foreach($user_agents as $user_string){
        if(preg_match("/".$user_string."/i",$_SERVER["HTTP_USER_AGENT"])) {
            return true;
        }
    }
}
// Let's NOT return "mobile" if it's an iPhone, because the iPhone can render normal pages quite well.
if(preg_match("/iphone/i",$_SERVER["HTTP_USER_AGENT"])) {
    return false;
}
// None of the above? Then it's probably not a mobile device.
return false;
}
    if (isMobile()) {
   header("location:$mobile");
  // if the function returned true, it's a mobile.
  //echo "mobile"; // delete this line in your code, and uncomment the next line
 // header('Location: http://www.yoursite.mobi/'); // let's redirect the page to   the mobile site
   }

希望这对你有帮助。

我使用这个：

$mobile= stripos( $_SERVER['HTTP_USER_AGENT'], 'mob');

它几乎每次都有效。

Javascript

var mobile= navigator.userAgent.toLowerCase().indexOf( 'mob');

-如果不是移动的，则为1；如果移动

，则任何其他值

看看这里：http://www.zytrax.com/tech/web/mobile_ids.html在这里：http://www.mobile-phone-specs.com/user-agent-browser/0/

这里有几乎所有用户代理字符串的列表。.

您可以使用CSS媒体查询来识别不同的设备（实际上是不同的设备功能，如设备宽度、dpi等）

对于CSS，你可以有不同的选择，比如为每种类型的设备提供单独的CSS，或者有一个流动的设计，这意味着对不同的设备大小使用相同的CSS比例。第二种方法设计起来有点复杂，但从未来可能出现的新设备来看要灵活得多。。
