JavaScript可以访问window.navigator.platform——一个表示浏览器平台的字符串: https://developer.mozilla.org/en-US/docs/Web/API/NavigatorID/platform < / p >

使用它来提取您需要(并且可以)的任何细节。请注意，并不能保证客户端实际使用了该平台，因为这可以很容易地以多种方式进行修改。

试一试:

console.log(window.navigator.platform);

我已经创建了一个用于解析User Agent字符串的库，名为伏都教。但是要注意，应该使用不来代替特征检测。

Voodoo所做的是解析userAgent字符串，该字符串在Navigator对象(window.navigator)中找到。并不是所有浏览器都会传递可靠的userAgent字符串，所以即使这是正常的方式，userAgent也不总是可信的。

最佳答案

如果你列出window.navigator的所有属性使用

console.log(navigator);

You'll see something like this

# platform = Win32
# appCodeName = Mozilla
# appName = Netscape
# appVersion = 5.0 (Windows; en-US)
# language = en-US
# mimeTypes = [object MimeTypeArray]
# oscpu = Windows NT 5.1
# vendor = Firefox
# vendorSub = 1.0.7
# product = Gecko
# productSub = 20050915
# plugins = [object PluginArray]
# securityPolicy =
# userAgent = Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7
# cookieEnabled = true
# javaEnabled = function javaEnabled() { [native code] }
# taintEnabled = function taintEnabled() { [native code] }
# preference = function preference() { [native code] }

注意，oscpu属性提供了Windows版本。另外，你应该知道:

'Windows 3.11' => 'Win16',
'Windows 95' => '(Windows 95)|(Win95)|(Windows_95)',
'Windows 98' => '(Windows 98)|(Win98)',
'Windows 2000' => '(Windows NT 5.0)|(Windows 2000)',
'Windows XP' => '(Windows NT 5.1)|(Windows XP)',
'Windows Server 2003' => '(Windows NT 5.2)',
'Windows Vista' => '(Windows NT 6.0)',
'Windows 7' => '(Windows NT 6.1)',
'Windows 8' => '(Windows NT 6.2)|(WOW64)',
'Windows 10' => '(Windows 10.0)|(Windows NT 10.0)',
'Windows NT 4.0' => '(Windows NT 4.0)|(WinNT4.0)|(WinNT)|(Windows NT)',
'Windows ME' => 'Windows ME',
'Open BSD' => 'OpenBSD',
'Sun OS' => 'SunOS',
'Linux' => '(Linux)|(X11)',
'Mac OS' => '(Mac_PowerPC)|(Macintosh)',
'QNX' => 'QNX',
'BeOS' => 'BeOS',
'OS/2' => 'OS/2',

我开始写一个脚本来读取可以在小提琴上测试的操作系统和浏览器版本。请随意使用和扩展。
断变化:
自2020年9月以来，新的Edge被检测到。所以“Microsoft Edge”是基于Chromium的新版本，旧Edge现在被检测为“Microsoft Legacy Edge”!< / p >

路德维希的解决方案太棒了。有几个修复(与操作系统无关，我不能把他的原始帖子作为评论，因为这太长了):

  1. IE 11不再自称为MS IE。
  2. IOS上的Chrome把自己伪装成Safari

platform.js似乎是一个很好的文件库来做到这一点。

使用的例子:

// on IE10 x86 platform preview running in IE7 compatibility mode on Windows 7 64 bit edition
platform.name; // 'IE'
platform.version; // '10.0'
platform.layout; // 'Trident'
platform.os; // 'Windows Server 2008 R2 / 7 x64'
platform.description; // 'IE 10.0 x86 (platform preview; running in IE 7 mode) on Windows Server 2008 R2 / 7 x64'


// or on an iPad
platform.name; // 'Safari'
platform.version; // '5.1'
platform.product; // 'iPad'
platform.manufacturer; // 'Apple'
platform.layout; // 'WebKit'
platform.os; // 'iOS 5.0'
platform.description; // 'Safari 5.1 on Apple iPad (iOS 5.0)'


// or parsing a given UA string
var info = platform.parse('Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7.2; en; rv:2.0) Gecko/20100101 Firefox/4.0 Opera 11.52');
info.name; // 'Opera'

你可以在navigator对象中找到操作系统的名称和版本，就像其他人回答的那样。标准的，跨浏览器的地方找到这个信息是在navigator.userAgent属性。但是，用户代理字符串因操作系统和浏览器的不同而有很大差异。

因此，我创建了一个脚本来封装这个逻辑，并以熟悉的方式报告最常见的操作系统和浏览器，比如http://www.whatsmybrowser.org。

我开源了脚本，并将其上传到github， https://github.com/keithws/browser-report。拉请求是受欢迎的!

我不能评论@Ian Ippolito的回答(因为如果我有代表的话我会评论的)，但根据他的评论链接，我相当确定你可以找到IOS的Chrome版本。https://developer.chrome.com/multidevice/user-agent?hl=ja列出UA为:Mozilla/5.0 (iPhone;CPU iPhone OS 10_3像Mac OS X) AppleWebKit/602.1.50 (KHTML，像壁虎)CriOS/56.0.2924.75移动/14E5239e Safari/602.1

所以这应该是可行的:

if ((verOffset = nAgt.indexOf('CriOS')) != -1) {
//Chrome on iPad spoofing Safari...correct it.
browser = 'Chrome';
version = nAgt.substring(verOffset + 6);//should get the criOS ver.
}

我还没能测试一下(否则我会改进他的答案)，因为我的iPad在家里，而我在工作，但我想我应该把它放在那里。

使用DetectOS.js。这是一个简单的JS定义，适用于没有依赖关系的流行操作系统和浏览器:

this.OS = this.searchString(this.dataOS())

return data[i].identity
}
} else if (dataProp) {
return data[i].identity

你可以使用javascript函数来检查用户的操作系统

  function getOS() {
var userAgent = window.navigator.userAgent,
platform = window.navigator.platform,
macosPlatforms = ['Macintosh', 'MacIntel', 'MacPPC', 'Mac68K'],
windowsPlatforms = ['Win32', 'Win64', 'Windows', 'WinCE'],
iosPlatforms = ['iPhone', 'iPad', 'iPod'],
os = null;


if (macosPlatforms.indexOf(platform) !== -1) {
os = 'Mac OS';
} else if (iosPlatforms.indexOf(platform) !== -1) {
os = 'iOS';
} else if (windowsPlatforms.indexOf(platform) !== -1) {
os = 'Windows';
} else if (/Android/.test(userAgent)) {
os = 'Android';
} else if (!os && /Linux/.test(platform)) {
os = 'Linux';
}


return os;
}


alert(getOS());

嘿，一个快速的解决方案，你可以考虑以下库:UAPARSER - https://www.npmjs.com/package/ua-parser-js

例子:

<script type="text/javascript" src="ua-parser.min.js"></script>
<script type="text/javascript">


var parser = new UAParser();
console.log(parser.getOS()) // will log  {name: "", version:""}

你也可以通过npm安装这个库，然后像这样导入它:

import { UAParser } from 'ua-parser-js';
let parser = new UAParser();
parser.getOS();

这个库是一个基于JS的用户代理字符串解析器(window.navigator. JS)。userAgent是浏览器上的用户代理)，所以你可以使用它获得其他细节，如浏览器，设备，引擎等，它也可以与node js一起工作。

如果你需要为库输入:https://www.npmjs.com/package/@types/ua-parser-js

我正在使用这个:)

getPlatform() {
const allPlatforms = ['Win32', 'Win64', 'Windows', 'WinCE', 'Android', 'iPhone', 'iPad', 'iPod'];
return allPlatforms.find(item => item === navigator.platform);
}

如果你正在创建一个网站或带有Electron的桌面应用程序，你可能需要获取客户端使用的操作系统的信息。因此，在这种特殊情况下，你可以使用一个名为window.navigator的全局属性。 如果你在控制台中使用console.log(navigator)记录属性，你将看到包含浏览器、操作系统等信息的子属性的整个对象

同样，如果你想创建一个本地NodeJS应用也是可以的!只需使用const os = require("os");调用os模块。然后在控制台中记录常量。你将得到一个完整的对象，但如果你想查看平台名称，你可以输入console.log(os.platform());，并确保在os.platform后添加一对括号，因为platform这里是一个函数!

希望这能有所帮助!

User-Agent字符串对于获取平台信息(OS, OS版本，cpu-arch等)不再可靠，因为可以重写它们，甚至浏览器的默认设置也不准确。 试着“console.log (navigator)“;

.在浏览器控制台中检查User-Agent字段

为了解决上述问题，有一个新的W3提案(https://wicg.github.io/ua-client-hints/)，它将允许用户请求关于平台的特定信息。截至2021年5月11日，只有铬的基础浏览器(Chrome、Edge、Opera、Brave…)实现了该规范(该提案仍是非正式的)。

获取平台信息的一种方法是服务器通过在初始响应中添加'< >强Accept-CH: Sec-CH-UA-Platform-Version < / >强'这样的报头来请求特定的信息，客户端的任何后续请求都将包含平台信息报头。欲了解更多信息，请参阅上面的链接。

要获得Javascript客户端中的信息，可以使用下面的代码(复制并粘贴到chrome控制台)。

let platformDetails = await navigator.userAgentData.getHighEntropyValues(["architecture",
"platform", "platformVersion", "model", "bitness", "uaFullVersion"]);
console.log(platformDetails);

如前所述，导航器。平台已弃用。我们应该使用导航器。但它仍然缺乏支持(firefox, safari在2022年不支持它)。

注意导航器。userAgentData只适用于通过https兼容的浏览器。

下面是一个脚本，它将使用UserAgentData，并返回到旧的操作方式。

function get_platform() {
// 2022 way of detecting. Note : this userAgentData feature is available only in secure contexts (HTTPS)
if (typeof navigator.userAgentData !== 'undefined' && navigator.userAgentData != null) {
return navigator.userAgentData.platform;
}
// Deprecated but still works for most of the browser
if (typeof navigator.platform !== 'undefined') {
if (typeof navigator.userAgent !== 'undefined' && /android/.test(navigator.userAgent.toLowerCase())) {
// android device’s navigator.platform is often set as 'linux', so let’s use userAgent for them
return 'android';
}
return navigator.platform;
}
return 'unknown';
}


let platform = get_platform();


// examples of use
let isOSX = /mac/.test(platform.toLowerCase()); // Mac desktop
let isIOS = ['iphone', 'ipad', 'ipod'].indexOf(platform.toLowerCase()) !== -1; // Mac iOs
let isApple = isOSX || isIOS; // Apple device (desktop or iOS)
let isWindows = /win/.test(platform.toLowerCase()); // Windows
let isAndroid = /android/.test(platform.toLowerCase()); // Android
let isLinux = /linux/.test(platform.toLowerCase()); // Linux
