Upload to csgostats not working

[mammuth]

There is a parse error when parsing the response from csgostats. First, I assumed that the uploads work nevertheless, but the upload of the share codes isn't working.

 Uploading Demo ShareCodes to https://csgostats.gg/:

Hey Max!

Thank you for raising the issue.
Seems they reworked the website a bit.
I quickly glanced over the request & response headers, after sending a POST request to the site.
Nowadays there is some http/2 and h3/alt-svc negotation going on,
which could be an issue for the (old) version of curl i compiled and linked against.
I'm not sure where the issue is exactly. It could also be the cloudflare protection.

Todo

• pinpoint issue
  • by recording and analyzing POST request & response headers to the website
  • create working curl command for POSTing from CLI
• update 3th party dependencies
  • curl
  • steam sdk (unrelated, but while i'm at it )
  • csgo protobufs (unrelated, but while i'm at it)
• fix ShareCodeUpload

Request

Response

{"status":"complete","data":{"msg":"Complete","index":null,"sharecode":"CSGO-WSACM-qX5Gv-ikbi3-Z6uOW-TGwPB","queue_id":3895818,"demo_id":3842461,"url":"https:\/\/csgostats.gg\/match\/3842461"},"error":0}

Notes for myself

These things solve the issue:

• lowered http negotiation to http/1.1 and disabled ALPN's & NPN negotations
• actually, removed sending a cookie !!
  • which implies that we don't need the pre-flight get request anymore? check

These things are nice to have in the cli tool, too:

• prepopulate dns-cache
• added connection close, not needed, but being nice to server here
  • add "connection close" header when sending the last new sharecode

ez game^^
