You can use stream()function as stated in documentation here.
您可以使用此处stream()文档中所述的函数。
According to documentation of dompdf,
When you use stream like this:
根据文档dompdf，当您像这样使用流时：
$dompdf->stream('filename.pdf');
In default, you will see a download dialouge box.
默认情况下，您将看到一个download dialouge box.
But, you can add parameter Attachmentvalue to falseso that you can view pdfin browser.
但是，您可以添加参数Attachment值，false以便您可以pdf在浏览器中查看。
Here is what you need to do:
以下是您需要做的：
$dompdf->stream("filename.pdf", array("Attachment" => false));
This might help you.

I've struggled with this and manage to make it work with the following snippet:
我一直在努力解决这个问题并设法使它与以下代码段一起工作：
$html = view('desktop.bill', $data)->render();
return @\PDF::loadHTML($html, 'utf-8')->stream(); // to debug + add the follosing headers in controller ( TOP LEVEL )
Besides the upper command, you will need to add on a TOP LEVEL, like first lines in the controller, the following hearders:
除了上面的命令，您还需要添加一个 TOP LEVEL，如控制器中的第一行，以下听者：
header('Content-type: application/pdf');
header('Content-Disposition: inline; filename="document.pdf"');
header('Content-Transfer-Encoding: binary');
