我正在使用critical为我的网站生成关键路径 CSS。我有一个 gulp 任务设置如下：

gulp.task('critical-css', function () {
    critical.generate({
        base: 'CriticalCss/',
        inline: false,
        src: 'index.html',
        dest: 'critical.min.css',
        minify: true,
        width: 320,
        height: 480
    }).then(function (output) {
        // Take 'output' and place it in masterpage
    });
});

我想知道是否可以获取output参数的值，即我的关键 CSS，并通过内联标记内的 gulp 将其注入我的母版页<style>？

我尝试使用我的 Masterpage 作为dest属性，但这不起作用，因为源文件不同，因为它是由服务器生成的 HTML 组成的。我也不能将 Masterpage 用作源文件，因为出于显而易见的原因，它并不是呈现给用户的真实表示。

像html-replace这样的东西会为此工作吗？

所以我设法用gulp-inject做到了这一点，它允许你很容易地动态地将文件或文件内容注入到你的页面中。

这是我最后的吞咽任务：

gulp.task('critical-css', function () {
    critical.generate({
        base: 'CriticalCSS/',
        inline: false,
        src: 'index.html',
        dest: 'critical.min.css',
        minify: true,
        width: 320,
        height: 480
    })
    .then(function (output) {
        gulp.src('./CMSTemplates/Web/MasterPages/Root.Master')
       .pipe(inject(gulp.src(['./CriticalCSS/*.css']), {
           starttag: '<!-- inject:{{path}} -->',
           transform: function (filePath, file) {
               return '<style type="text/css">'
                        + output +
                      '</style>';
           }
       }))
       .pipe(gulp.dest('./CMSTemplates/Web/MasterPages'));
    });
});

它最终取代了这个：

<!-- inject:/CriticalCSS/critical.min.css-->
<!-- endinject -->

有了这个：

<!-- inject:/CriticalCSS/critical.min.css-->
