你在用拉威尔吗？为什么不使用laravel snappy

要使用snappy laravel，您需要按照此处的说明操作，或以下，我试图让它们更容易阅读和理解：

1。从这里下载wkhtmltopdfhttps://wkhtmltopdf.org/downloads.html

2。软件包安装：composer需要barryvdh/laravel snappy

3。在（app.php）providers数组中添加Barryvdh\Snappy\ServiceProvider:：class，

4。在（app.php）别名数组中添加“PDF”=>Barryvdh\Snappy\Facades\SnappyPdf:：class，“SnappyImage”=>Barryvdh\Snappy\Facades\SnappyImage:：class，

5。运行php artisan供应商：publish--provider=“Barryvdh\Snappy\ServiceProvider”

6。在（snappy.php）中，根据wkhtmltopdf的安装路径编辑二进制路径，如下所示：

返回数组(

))

您是否安装了提供PDF类的软件包？
