bitfinex api v2 错误，密钥无效

我正在尝试对其新的 v2 api 进行基本的经过身份验证的 api 调用，并返回无效的 api 密钥错误。

我重新发出 api 密钥只是为了验证，同样的错误。

from time import time
import urllib.request
import urllib.parse
import hashlib
import hmac

APIkey = b'myapikeyyouarenotsupposedtosee'
secret = b'myceeeeecretkeyyyy'

url = 'https://api.bitfinex.com/v2/auth/r/wallets'

payload = {
    #'request':'/auth/r/wallets',
    'nonce': int(time() * 1000),
}

paybytes = urllib.parse.urlencode(payload).encode('utf8')
print(paybytes)

sign = hmac.new(secret, paybytes, hashlib.sha512).hexdigest()
print(sign)

headers = {
    'Key': APIkey,
    'Sign': sign
}

req = urllib.request.Request(url, headers=headers, data=paybytes)
with urllib.request.urlopen(req) as response:
    the_page = response.read()
    print(the_page)

如何对 bitfinex 的新 v2 API 进行经过身份验证的 api 调用？

你的标题是错误的。我也尝试这样做并尝试使用示例代码 https://bitfinex.readme.io/v2/docs/rest-auth来自 bitfinex v2 api 文档，但是他们的示例包含一个错误，因为他们需要首先将字符串编码为 UTF-8 字节数组。所以我已经修复了它并在下面发布了整个示例。

        # Returns a nonce
        # Used in authentication
        return str(int(round(time.time() * 10000)))

    def _headers(self, path, nonce, body):
        secbytes = self.SECRET.encode(encoding='UTF-8')
        signature = "/api/" + path + nonce + body

        resp = requests.post(url, headers=headers, data=rawBody, verify=True)
        return resp

    def active_orders(self):
        # Fetch active orders
        response = self.req("v2/auth/r/orders")
        if response.status_code == 200:
          return response.json()
        else:
          print('error, status_code = ', response.status_code)
          return ''

# fetch all your orders and print out
client = BitfinexClient()
result = client.active_orders()
print(result)
