如何使用OKEx SHA256加密和Base64编码用websockets登录Base64 API V5？

虽然使用REST的OKEx API的早期版本已经回答了这个问题，但是使用websockets的最新版本5没有回答这个问题。医生来了。
我得到了下面的错误{"event":"error","msg":"Invalid sign","code":"60007"}，所以签名字符串算法肯定有问题，但我似乎无法确定我在哪里出错。
import hmac
import json
import time
import hashlib
import asyncio
import websockets
passphrase = "XXXX"
secret_key = b"XXXX"
api_key = "XXXX"
timestamp = int(time.time())
print("timestamp: " + str(timestamp))
sign = str(timestamp) + 'GET' + '/users/self/verify'
total_params = bytes(sign, encoding= 'utf-8')
signature = hmac.new(bytes(secret_key, encoding= 'utf-8'), total_params, digestmod=hashlib.sha256).digest()
signature = base64.b64encode(signature)
print("signature = {0}".format(signature))
async def main():
msg = \
{
"op": "login",
"args": [
{
"apiKey": f'{api_key}',
"passphrase": f'{passphrase}',
"timestamp": f'{timestamp}',
"sign": f'{signature}'
}
]
}
async with websockets.connect('wss://wspap.okx.com:8443/ws/v5/private?brokerId=9999') as websocket:
print(msg)
await websocket.send(json.dumps(msg))
response = await websocket.recv()
print(response)

我想通了。在发送签名之前，需要将其从字节字符串varible转换回字符串变量。
添加以下代码行可执行以下操作：signature = str(signature, 'utf-8')
import json
import time
import hmac
import hashlib
import base64
import asyncio
import websockets
passphrase = "XXXX"
secret_key = "XXXX"
api_key = "XXXX"
timestamp = int(time.time())
print("timestamp: " + str(timestamp))
sign = str(timestamp) + 'GET' + '/users/self/verify'
total_params = bytes(sign, encoding= 'utf-8')
signature = hmac.new(bytes(secret_key, encoding= 'utf-8'), total_params, digestmod=hashlib.sha256).digest()
signature = base64.b64encode(signature)
signature = str(signature, 'utf-8')
print("signature = {0}".format(signature))
async def main():
msg = \
{
"op": "login",
"args": [
{
"apiKey": f'{api_key}',
"passphrase": f'{passphrase}',
"timestamp": f'{timestamp}',
"sign": f'{signature}'
}
]
}
async with websockets.connect('wss://wspap.okx.com:8443/ws/v5/private?brokerId=9999') as websocket:
print(msg)
await websocket.send(json.dumps(msg))
response = await websocket.recv()
print(response)
