php - Laravel-Snappy 抛出错误 500 没有更多信息

Question

我想使用 barryvdh\laravel-snappy 创建 PDF 文件。我遵循了 github 页面上的所有步骤，但每当我使用像

这样的函数时

$pdf->output();
$pdf->download("test.pdf");

我收到服务器错误。

我尝试使用安装程序以及 Composer 依赖项在 Windows 上安装 wkthmltopdf。我清除了缓存，使用了 composer update、dump-autoload 等。

这是我 Controller 中的函数:

public function createInvoice($id)
    {
        $data = ["data" => "data"];
        $pdf = PDF::loadView("invoice.default", $data);

        dd($pdf);
        return response()->json([
            "pdf" => base64_encode($pdf->output())
        ]);
    }

我的 snappy.php 配置:

'pdf' => [
        'enabled' => true,
        'binary'  => base_path('vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64'),
        'timeout' => false,
        'options' => [],
        'env'     => [],
    ],

    'image' => [
        'enabled' => true,
        'binary'  => base_path('vendor/h4cc/wkhtmltoimage-amd64/bin/wkhtmltoimage-amd64'),
        'timeout' => false,
        'options' => [],
        'env'     => [],
    ],

我的 app.php 配置:

'providers' => [
.
.
    Barryvdh\Snappy\ServiceProvider::class,

.
.
.

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

当我在 $pdf 上使用 dd 时，在调用输出、下载、内联等函数之前，我得到以下响应:

}

当我调用其中一个函数时，然后:

{
    "message": "Server Error"
}

Answer 1

将二进制路径改为

  'pdf' => array(
        'enabled' => true,
        'binary'  => '/usr/local/bin/wkhtmltopdf', //for ubuntu
        // 'binary'  => '"C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf.exe"', //for windows
        'timeout' => false,
        'options' => array(),
        'env'     => array(),
    ),
    'image' => array(
        'enabled' => true,
        'binary'  => '/usr/local/bin/wkhtmltoimage', //for ubuntu
        // 'binary'  => '"C:\Program Files\wkhtmltopdf\bin\wkhtmltoimage.exe"', //for windows
        'timeout' => false,
        'options' => array(),
        'env'     => array(),
    ),

你已经为 ubuntu 设置好了。
