Upgrading from 0.1.0 to 0.3.1

[mrossard]

Hi,

I've been using this bundle since its early days on a small project, and i'm having some trouble upgrading it : i seem to get empty contents even though the generation seems to be just fine.

From what i could gather using my debugger, my call to $htmlPdfBuilder->generate()->process() (i need the pdf as a string) ends up calling Sensiolabs\GotenbergBundle\Processor\NullProcessor with chunks that look fine, but it obviously does nothing with them.

Any clue as to what I could be doing wrong?

The code is extremely simple and does seem to get me a correct response before i try to get its contents :

$builder = $this->pdf->html();
if (null !== $headerTemplate) {
    $builder->header($headerTemplate, ['data' => $data]);
}
if (null !== $footerTemplate) {
    $builder->footer($footerTemplate, ['data' => $data]);
}

return $builder->content($template, ['data' => $data])->generate()->process();
//In 0.1.0 was return $builder->content($template, ['data' => $data])->generate()->getContent();

Hello @mrossard,

The builder is set to use the NullProcessor by default, meaning no action will be taken.

If you wish to obtain a SplFileInfo, you should utilize the FileProcessor. Alternatively, to acquire a resource, you should employ the TempfileProcessor.

What objective are you aiming to accomplish with the string you retrieved?

I had just found https://github.com/sensiolabs/GotenbergBundle/blob/main/docs/processing.md , sorry.

I'm returning the file as a string in a PdfEncoder in a project using api platform, it needs to implement Symfony\Component\Serializer\Encoder\EncoderInterface:encode(), which returns a string.

That being said, TempfileProcessor doesn't exist in 0.3.1, neither via composer nor via the zip package?

Indeed! Spoiler alert: a new version is coming with this processor.

Is the serialization needed? You could directly return the StreamedResponse from $builder->process()->stream() and enjoy the benefits of PDF streaming.

in the meantime i copy/pasted it in my project and it works fine, thanks!

I'm not sure i can skip the normalization/serialization part of api platform for a specific accept header, but that could be nice. I'll ask @soyuka if i find some time, it'd be nice for big documents.
