A user is able to upload a file. During the upload the file is scanned. If there is an issue with the file Symfony returns a Response(400) and the rest of the file is not uploaded, saving the user and the host time and bandwidth.
This is done via \Symfony\Component\HttpFoundation\Request::getContent(true)
$resource = $request->getContent(true);
The file is scanned a line at a time using:
fgets($resource);
The resource is also closed before the response is sent to the user:
fclose($resource);
However there is unexpected and strange behaviour happening for some user clients.
For example wget:
wget -4 --no-check-certificate --method PUT --timeout=0 --header 'Authorization: Bearer xxx' --body-file='xxx' 'https://example.com/xxx' --content-on-error -d -O -
Response hangs:
---request begin---
PUT /xxx HTTP/1.1
User-Agent: Wget/1.20.3 (linux-gnu)
Accept: */*
Accept-Encoding: identity
Host: xxx
Connection: Keep-Alive
Content-Length: 37767602
Authorization: Bearer xxx
---request end---
[writing BODY file xxx ...
It appears that wget does not understand the upload does not need to be completed, is this a header that php is failing to send or a flag required in the wget command?
A similar command in curl works
curl -k --location --request PUT 'https://example.com/xxx' \
--header 'Authorization: Bearer xxx' \
--data-binary '@/xxx'
Response
