压缩 HTML 加速网页响应—— renatomarinho/laravel-page-speed，扩展包可以自动的优化网站，将HTML加速输出显示在客户端浏览器。
项目地址：https://github.com/renatomarinho/laravel-page-speed
安装命令：
$ composer require renatomarinho/laravel-page-speed
扩展包中使用了中间件
//app/Http/Kernel.php
protected $middleware = [
...
\RenatoMarinho\LaravelPageSpeed\Middleware\InlineCss::class, //转变html中的行内样式
\RenatoMarinho\LaravelPageSpeed\Middleware\ElideAttributes::class, //去除html中多余的属性
\RenatoMarinho\LaravelPageSpeed\Middleware\TrimUrls::class, //去除html中所有的协议部分http或https，
\RenatoMarinho\LaravelPageSpeed\Middleware\InsertDNSPrefetch::class, //检测html中所有的链接，并进行预加载
\RenatoMarinho\LaravelPageSpeed\Middleware\RemoveComments::class, //去除html中所有的注释信息
\RenatoMarinho\LaravelPageSpeed\Middleware\RemoveQuotes::class, //去除html标签中的引号
\RenatoMarinho\LaravelPageSpeed\Middleware\CollapseWhitespace::class, //去除html中所有的换行、空格等信息
]
注意：响应式中间件的读取顺序是从下向上。
我们将中间件注册在web，所有通过web访问的数据都可以进行压缩
protected $middlewareGroups = [
'web' => [
\App\Http\Middleware\EncryptCookies::class,
\Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
\Illuminate\Session\Middleware\StartSession::class,
// \Illuminate\Session\Middleware\AuthenticateSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,
\App\Http\Middleware\VerifyCsrfToken::class,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
