Question

我正在使用berryvdh/dompdf生成PDF，并将其作为电子邮件附件发送：

$pdf = PDF::loadView($view, compact('******'));
$pdf->setOptions(['dpi' => 300 ]);
$output = $pdf->save('pdf/' . $name_pr);

在电子邮件功能中：

$message->attach($file, [
                        'as' => $reference.'.pdf',
                        'mime' => 'application/pdf',
                    ]);

在我的pdf视图中：

但是当收到电子邮件时，图像将被删除。在没有$pdf->setOptions(['dpi' => 300 ]);的情况下， pdf 会随图像一起加载，但是设置pdf对齐方式时我需要启用此选项，是否有解决此问题的方法？

谢谢。

Answer 1

通过调用公共路径并将图像路径连接到我的视图中，可以解决此问题

{{public_path().'/images/td.jpg'}}

感谢所有回答我的问题的人

Answer 2

我通过将图像转换为base64解决了这个问题。就我而言，我只是使用了在Google上找到的转换器，因为我的图片是静态的，但是如果必须动态转换，则可以使用它

$path = 'myfolder/myimage.png';
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = file_get_contents($path);
$base64 = 'data:image/' . $type . ';base64,' . base64_encode($data);
