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。

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!

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。

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
