unable to read price_sheet from CMsgStoreGetUserData

[Therepower]

hey,

i try to fetch CSGO in-game store prices via CMsgStoreGetUserData.

message CMsgStoreGetUserData {
	optional fixed32 price_sheet_version = 1;
	optional int32 currency = 2;
}

 

message CMsgStoreGetUserDataResponse {
	optional int32 result = 1;
	optional int32 currency_deprecated = 2;
	optional string country_deprecated = 3;
	optional fixed32 price_sheet_version = 4;
	optional bytes price_sheet = 8;
}

 

When i receive the "CMsgStoreGetUserDataResponse" i can read result, price_sheet_version without problems but "price_sheet" itself is provided as bytes. When i try to read it i get some unreadable text. I also tried to parse it with  binarykvparser which gives  an error "KV type 48 encountered at offset 207"

How could i read the data provided by price_sheet?

thank you in advance

I have no idea what format price_sheet is encoded in.

thanks for your response.

any idea how i could find the encoding type? 

this is how it looks like: https://prnt.sc/ytol2e

I don't know. My best guess would be that it's either protobuf or binary KV, but that doesn't look like either. It could possibly be compressed.

I'm trying to do the same thing, I'm using python though. For me the price_sheet starts with b"LZMA\", so I'm guessing it's compressed with LZMA but I wasn't able to decompress it

[Dr. McKay]

That sounds like a reasonable assumption. Game content downloads are sometimes compressed with LZMA, so Valve using it somewhere else makes perfect sense.
