我需要在内部网应用程序上使用一些谷歌字体。客户端可能有也可能没有互联网连接。阅读许可条款,这似乎是法律允许的。

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。

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

$obj = new GoogleFontsDownloader;
        
if(isset($_GET['url']) && !empty($_GET['url']))
{
    $obj->generate($_GET['url']);
}

if(isset($_GET['download']) && !empty($_GET['download']) && $_GET['download']=='true')
{
    $obj->download();
}

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" />

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。
