这在法律上是允许的，只要你遵守字体许可的条款——通常是OFL。

你需要一套网页字体格式，而font Squirrel Webfont Generator可以生成这些格式。

但是OFL要求在修改字体时重命名它们，使用生成器意味着修改它们。

请记住，我的回答已经过时了很多。

下面还有一些技术上更复杂的答案，例如:

Neverpanic/google-font-download google-webfont-helper 本地字体

所以，不要因为这是目前公认的答案，就以为这是最好的答案。

你现在也可以下载谷歌的整个字体集通过github在他们的谷歌/字体资源库。它们还提供字体的约420MB压缩快照。

You first download your font selection as a zipped package, providing you with a bunch of true type fonts. Copy them somewhere public, somewhere you can link to from your css.

On the google webfont download page, you'll find a include link like so:

http://fonts.googleapis.com/css?family=Cantarell:400,700,400italic,700italic|Candal

It links to a CSS defining the fonts via a bunch of @font-face defintions.

Open it in a browser to copy and paste them into your own CSS and modify the urls to include the right font file and format types.

So this:

    @font-face {
      font-family: 'Cantarell';
      font-style: normal;
      font-weight: 700;
      src: local('Cantarell Bold'), local('Cantarell-Bold'), url(http://themes.googleusercontent.com/static/fonts/cantarell/v3/Yir4ZDsCn4g1kWopdg-ehHhCUOGz7vYGh680lGh-uXM.woff) format('woff');
    }

becomes this:

    /* Your local CSS File */
    @font-face {
        font-family: 'Cantarell';
        font-style: normal;
        font-weight: 700;
        src: local('Cantarell Bold'), local('Cantarell-Bold'), url(../font/Cantarell-Bold.ttf) format('truetype');
    }

As you can see, a downside of hosting the fonts on your own system this way is, that you restrict yourself to the true type format, whilst the google webfont service determines by the accessing device which formats will be transmitted.

Furthermore, I had to add a .htaccess file to my the directory holding the fonts containing mime types to avoid errors from popping up in Chrome Dev Tools.

For this solution, only true type is needed, but defining more does not hurt when you want to include different fonts as well, like font-awesome.

#.htaccess
AddType application/vnd.ms-fontobject .eot
AddType font/ttf .ttf
AddType font/otf .otf
AddType application/x-font-woff .woff

CSS文件的内容(来自include URL)取决于我从什么浏览器查看它。例如，当使用Chrome浏览器浏览http://fonts.googleapis.com/css?family=Open+Sans时，该文件只包含WOFF链接。使用Internet Explorer(如下)，它包括EOT和WOFF。我把所有链接都粘贴到浏览器里下载。

@font-face {
  font-family: 'Open Sans';
  font-style: normal;
  font-weight: 400;
  src: url(http://themes.googleusercontent.com/static/fonts/opensans/v6/cJZKeOuBrn4kERxqtaUH3fY6323mHUZFJMgTvxaG2iE.eot);
  src: local('Open Sans'), local('OpenSans'), url(http://themes.googleusercontent.com/static/fonts/opensans/v6/cJZKeOuBrn4kERxqtaUH3fY6323mHUZFJMgTvxaG2iE.eot) format('embedded-opentype'), url(http://themes.googleusercontent.com/static/fonts/opensans/v6/cJZKeOuBrn4kERxqtaUH3T8E0i7KZn-EPnyo3HZu7kw.woff) format('woff');
}

当你拥有自己的网页字体时，你需要正确地链接到每种字体类型，处理遗留的浏览器错误等。当您使用谷歌Web Fonts(由谷歌托管)时，谷歌自动链接到该浏览器的正确字体类型。

我写了一个bash脚本，在谷歌的服务器上使用不同的用户代理获取CSS文件，将不同的字体格式下载到本地目录，并编写包含它们的CSS文件。注意，该脚本需要Bash版本4.x。

请参阅https://neverpanic.de/blog/2014/03/19/downloading-google-web-fonts-for-local-hosting/获取脚本(我在这里不复制它，所以我只需要在需要时在一个地方更新它)。

编辑:移动到https://github.com/neverpanic/google-font-download

我有一个类似于@neverpanic的PHP脚本，自动从谷歌下载CSS和字体(暗示和未暗示)。然后，它根据用户代理从您自己的服务器提供正确的CSS和字体。它有自己的缓存，所以用户代理的字体和CSS只会被下载一次。

它还处于早期阶段，但可以在这里找到:DaAwesomeP / php-offline-fonts

很好的解决方案是google-webfonts-helper ．

它允许你选择多个字体变体，这节省了很多时间。

我在一个grunt任务中使用了grunt-local-googlefont。

module.exports = function(grunt) {

    grunt.initConfig({
       pkg: grunt.file.readJSON('package.json'),

        "local-googlefont" : {
            "opensans" : {
                "options" : {
                    "family" : "Open Sans",
                    "sizes" : [
                        300,
                        400,
                        600
                    ],
                    "userAgents" : [
                        "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0)",  //download eot
                        "Mozilla/5.0 (Linux; U; Android 4.1.2; nl-nl; GT-I9300 Build/JZO54K) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30", //download ttf
                        "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1944.0 Safari/537.36" //download woff and woff2
                    ],
                    "cssDestination" : "build/fonts/css",
                    "fontDestination" : "build/fonts",
                    "styleSheetExtension" : "css",
                    "fontDestinationCssPrefix" : "fonts"

                }
            }
        }
    });

    grunt.loadNpmTasks('grunt-local-googlefont');
 };

然后，要检索它们:

grunt local-googlefont:opensans

注意，我使用的是原始版本的一个分支，它在检索名称中有空格的字体时工作得更好。

实际上，您可以直接从谷歌下载所有字体格式变体，并将它们包含在您的css中，以从您的服务器提供服务。这样你就不必担心谷歌跟踪你网站的用户。然而，缺点可能会减慢你自己的发球速度。字体对资源的要求很高。我还没有在这个问题上做任何测试，不知道是否有人有类似的想法。

由于您希望在自己的服务器上托管所有字体(或部分字体)，您可以从这个repo下载字体并以您想要的方式使用它:https://github.com/praisedpk/Local-Google-Fonts

如果你只是想这样做来解决谷歌字体附带的浏览器缓存问题，你可以使用替代字体CDN，并包括字体为:

<link href="https://pagecdn.io/lib/easyfonts/fonts.css" rel="stylesheet" />

或一种特定的字体，如:

<link href="https://pagecdn.io/lib/easyfonts/lato.css" rel="stylesheet" />

编辑:正如luckyrumo指出的那样，字体被放弃了，取而代之的是:https://github.com/fontsource/fontsource

如果您正在使用Webpack，您可能会对这个项目感兴趣:https://github.com/KyleAMathews/typefaces

例如，你想使用Roboto字体:

npm install typeface-roboto --save

然后把它导入你的应用的入口点(主js文件):

import 'typeface-roboto'

你可以从https://github.com/google/fonts下载原始字体

之后，使用字体游弋工具将您的大型Unicode字体分成多个子集(例如拉丁，西里尔)。您应该使用该工具执行以下操作:

为您支持的每种语言生成子集 使用unicode范围子集节省带宽 删除臃肿从你的字体和优化他们的网页 将字体转换为压缩的woff2格式 为旧浏览器提供.woff备份 自定义字体加载和渲染 使用@font-face规则生成CSS文件 自托管web字体或在本地使用它们

字体游侠：https://www.npmjs.com/package/font-ranger

附注:你也可以使用Node.js API自动化这个过程

您可以遵循使用PHP开发的脚本。 在那里你可以下载任何谷歌字体使用脚本。 它将下载字体，并创建一个CSS文件和存档压缩。 您可以从GitHub https://github.com/souravmsh/google-fonts-downloader下载源代码

最简单的方法-使用google-webfonts-helper

假设我们想要托管字体Red Rose:

Open google-webfonts-helper and filter for the required font on top left (type Red Rose and enter..) Choose from the charsets (default is latin; select others like latin-ext if you want extended support) Select the styles (deafult is regular) From the Copy CSS tab Select Modern Browser if you wish to support only modern browsers (woff2, woff) Select Best Support if you wish to support all browsers (I chose this - woff2, woff,ttf,svg,eot) In case your font files do not reside in ../fonts/ path, you can edit it to represent your actual path (for me it was ../assets/fonts/) Copy the CSS and keep for future use Download the zip file named red-rose-v1-latin-ext_latin; unzip it and place all fonts directly into your assets/fonts directory (based on what you gave earlier) In your stylesheet where you wish to embed, paste the copied CSS. It will look like the below if you chose these options

/* red-rose-regular - latin-ext_latin */
@font-face {
  font-family: 'Red Rose';
  font-style: normal;
  font-weight: 400;
  src: url('../assets/fonts/red-rose-v1-latin-ext_latin-regular.eot'); /* IE9 Compat Modes */
  src: local('Red Rose Regular'), local('RedRose-Regular'),
       url('../assets/fonts/red-rose-v1-latin-ext_latin-regular.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
       url('../assets/fonts/red-rose-v1-latin-ext_latin-regular.woff2') format('woff2'), /* Super Modern Browsers */
       url('../assets/fonts/red-rose-v1-latin-ext_latin-regular.woff') format('woff'), /* Modern Browsers */
       url('../assets/fonts/red-rose-v1-latin-ext_latin-regular.ttf') format('truetype'), /* Safari, Android, iOS */
       url('../assets/fonts/red-rose-v1-latin-ext_latin-regular.svg#RedRose') format('svg'); /* Legacy iOS */
}

/* Red Rose will now be available for use in your stylesheet, provide this font */

:root {
  font-family: 'Red Rose', cursive, sans-serif;
}

这一切!
