laravel 中使用的pdf 扩展包 laravel-snappy(已解决中文乱码)

Centos7 安装 wkhtmltopdf

1、先查看系统是 32 位的还是 64 位的

uname -a

2、通过 composer 安装 wkhtmltopdf

32位:
$ composer require h4cc / wkhtmltopdf-i386 0.12.x
$ composer require h4cc / wkhtmltoimage-i386 0.12.x
64位:
$ composer require h4cc/wkhtmltopdf-amd64 0.12.x
$ composer require h4cc/wkhtmltoimage-amd64 0.12.x

3、接下来将安装好的 wkhtmltopdf 复制到 Linux 系统可执行命令的目录中

cp vendor/h4cc/wkhtmltoimage-amd64/bin/wkhtmltoimage-amd64 /usr/local/bin/
cp vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64 /usr/local/bin/
//并使其可执行：
chmod +x /usr/local/bin/wkhtmltoimage-amd64 
chmod +x /usr/local/bin/wkhtmltopdf-amd64

Laravel 安装 snappy

composer require barryvdh/laravel-snappy

配置（可选，Laravel 5.5+ 自动发现、不用管1、2步骤）
1、将 ServiceProvider 添加到 config/app.php 中的 providers 数组中

Barryvdh\Snappy\ServiceProvider::class,

2、将 Facades 添加到 config/app.php 中的 aliases 数组中

'PDF' => Barryvdh\Snappy\Facades\SnappyPdf::class,
'SnappyImage' => Barryvdh\Snappy\Facades\SnappyImage::class,

3、生成配置文件

php artisan vendor:publish --provider="Barryvdh\Snappy\ServiceProvider"

注意：config 文件夹中的 snappy.php 就是其配置文件，binary 指向的就是上面安装的 wkhtml 相关路径.

  'pdf' => ['enabled' => true,'binary'  => env('WKHTML_PDF_BINARY', '/usr/local/bin/wkhtmltopdf-amd64'),'timeout' => false,'options' => [],'env'     => [],],'image' => ['enabled' => true,'binary'  => env('WKHTML_IMG_BINARY', '/usr/local/bin/wkhtmltoimage-amd64'),'timeout' => false,'options' => [],'env'     => [],],
