dompdf 未从 Laravel 8 和 Livewire 视图下载 PDF

Question

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

我可以在 Livewire 之外获取下载 pdf 的视图，但似乎无法让它在 Livewire 视图内工作。我已经尝试了所有我能想到的配置，但仍然遇到障碍。我要么收到Undefined variable: workorder错误，要么根本没有错误，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');
}

Answer 1

给你，刚刚发现这个。把我固定住了。我唯一需要更改的是$viewData变量，我只需将其设为数组 -['viewData' => $viewData]然后我就可以在我的视图中访问它。

这是链接失效时的代码：

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