please explain? api signature example
(Update: still stuck after changes made from John's comment)
I am hoping for somebody to kindly try to explain in layman's terms how the signature is generated in the following example? I am pretty much stuck at this point.. I get the same result in an online hash generator (see picture below) and in my own code; but it differs from the example in the website (also pictured below).
https://www.gate.io/docs/apiv4/en/#authentication edit: website seems only reachable through google search, direct link gives 404? So I attached the page as image, see below
Request: List all orders
GET /api/v4/futures/orders?contract=BTC_USD&status=finished&limit=50 HTTP/1.1
secret:
secret
resulting signature string (edit: updated, thanks @John Glenn)：
GET\n/api/v4/futures/orders\ncontract=BTC_USD&status=finished&limit=50\ncf83e1357eefb8bdf1542850d66d8007d620e4050b5715dc83f4a921d36ce9ce47d0d13c5d85f2b0ff8318d2877eec2f63b931bd47417a81a538327af927da3e\n1541993715
(note that in the example on the website, there are line breaks for readability)
Signature generated according to the example:
eae42da914a590ddf727473aff25fc87d50b64783941061f47a3fdb92742541fc4c2c14017581b4199a1418d54471c269c03a38d788d802e2c306c37636389f0
Explanation from the website:
Signature generation method is HexEncode(HMAC_SHA512(secret, signature_string)), i.e., the hexadecimal digest output of HMAC-SHA512 with APIv4 secret as secret and signature string as message.
But if I put it into a HMAC-SHA512 generator (e.g., https://www.javainuse.com/hmac), the value I get is:
58000238bf5eef226028e108df259184f14bf3021eb27c324a808334d187da42c38f4510b30215ee9b0c05d6352396e99f67fa920079746bb4dfd70506592f6d
I suspect I am missing a very essential point but I am quite lost at this time..
thank you very much for your help!
Solved!
The "\n" were not regular expressions but actual newlines in the example. In other words, the newlines should be entered as ascii newline character.
Then I got the same result in the generator as from the website.
