[英]F# converting hmac python into f#
How would I convert this Python code into F# " 我如何将这段Python代码转换为F#”
message = nonce + client_id + api_key
signature = hmac.new(API_SECRET, msg=message, digestmod=hashlib.sha256).hexdigest().upper()
My code so far to achieve this: 到目前为止,我的代码实现了这一点:
let message =string(nonce)+ client_id + api_key
let signature = HMACSHA256.Create(API_secret+message)
Simple issue is I cannot find what represents the hexdigest()
function in F#. 一个简单的问题是我找不到F#中代表
hexdigest()
函数的内容。
Also, do I combine the API_Secret
with the message as I have done or must they be separated? 另外,是否将
API_Secret
与消息结合起来,还是必须将它们分开?
I think you need somethink like this: 我认为您需要这样的想法:
let hexdigest (bytes : byte[]) =
let sb = System.Text.StringBuilder()
bytes |> Array.iter (fun b -> b.ToString("X2") |> sb.Append |> ignore)
string sb
let signature =
use hmac = new HMACSHA256.Create(API_secret)
hmac.ComputeHash(message)
|> hexdigest
The part with the StringBuilder is what hexdigest
does in python (if I get hexdigest
right) StringBuilder的部分是
hexdigest
在python中的作用(如果我正确使用了hexdigest
)
