还有更简单的例子可用。
<img src="data:image/png;base64, {!! base64_encode(QrCode::format('png')->size(100)->generate('QrCode as PNG image!')) !!} ">

If you are formatting it as png file format, you need to include it with a <img>tag.
如果要将其格式化为 png 文件格式，则需要将其包含在<img>标签中。
Taken from the documentation
取自文档
//Inside of a blade template.
<img src="{!!$message->embedData(QrCode::format('png')->generate('Embed me into an e-mail!'), 'QrCode.png', 'image/png')!!}">
You can also do this:
你也可以这样做：
$png = QrCode::format('png')->size(512)->generate(1);
$png = base64_encode($png);
echo "<img src='data:image/png;base64," . $png . "'>";

In controller
在控制器中
$path = getenv('IMAGE_URL')."/img/logo.png";
$png = QrCode::format('png')->merge($path, .17, true)->size(300)->errorCorrection('H')->generate($data);
$png = base64_encode($png);
In blade file
在刀片文件中
<img src='data:image/png;base64,{{$png}}'>
