php - dompdf 不从 Laravel 8 和 Livewire View 下载 PDF

Question

我正在使用 dompdf在我的 Laravel v8.26.1 应用程序中。我也在使用 Laravel Livewire v1.3.5。
我可以查看在 Livewire 之外下载 pdf 的 View ，但似乎无法让它在 Livewire View 中工作。我已经尝试了我能想到的所有配置，但一直遇到障碍。我要么得到一个 Undefined variable: workorder错误，或者根本没有错误，但也没有下载。

public function generatePDF($id)
{
    $record = Workorder::find($id);
    $data = [
        'project_id' => $record->project_id,
        'project_name' => $record->project_name,
        'customer_id' => $record->customer_id,
        'generator_id' => $record->generator_id,
        'workorder_po_number' => $record->workorder_po_number,
        'workorder_number' => $record->workorder_number,
        'prevailing_wage' => $record->prevailing_wage,
    ];
    $pdf = PDF::loadView('livewire.admin.workorders.print', $data);
    return $pdf->download('demo.pdf');
}

Here you go ，刚发现这个。把我修好。我唯一需要改变的是 $viewData变量，我只需要把它变成一个数组 - ['viewData' => $viewData]然后我可以在我看来访问它。
这是链接发生故障时的代码:

$pdfContent = PDF::loadView('view', $viewData)->output();
return response()->streamDownload(
     fn () => print($pdfContent),
     "filename.pdf"
);
