dompdf 未从 Laravel 8 和 Livewire 视图下载 PDF

Question

我在我的 Laravel v8.26.1 应用程序中使用 dompdf。我也在使用 Laravel Livewire v1.3.5.

我可以获得在 Livewire 外部下载 pdf 的视图，但似乎无法在 Livewire 视图中使用它。我已经尝试了所有我能想到的配置，但将运行保留在路障中。我收到 Undefined variable: workorder 错误，或者根本没有错误，但也没有下载。

路线

...
Route::livewire('/workorder/{workorder}/print', 'admin.workorders.printer')->name('admin.workorder.print')->layout('layouts.admin');
...

livewire/admin/workorders/print.blade

...
<div>
  <button wire:click="generatePDF({{$workorder->id}})">Create PDF</button>
</div>
...

livewire/admin/workorders/printer.php

...
use Barryvdh\DomPDF\Facade as PDF;
...
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，刚找到这个。把我修好。我唯一需要更改的是 $viewData 变量，我只需要将其设为数组 - ['viewData' => $viewData] 然后我就可以在我的视图中访问它。

这里是代码以防 link 出现故障：

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