Bitfinex API V2错误，无效的密钥

Question

我正在尝试对其新的V2 API进行基本身份验证的API调用，并返回了无效的API键错误。

我重新发出了API键以验证相同的错误。

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进行身份验证的API？

您的标题错了。我还试图做到这一点，并尝试使用Bitfinex V2 API文档中的示例代码，但是他们的示例包含一个错误，因为它们需要首先将字符串编码到UTF-8字节数组中。因此，我已经修复了它并在下面发布了整个示例。

#
# Example Bitfinex API v2 Auth Python Code
#
import requests  # pip install requests
import json
import base64
import hashlib
import hmac
import os
import time #for nonce
class BitfinexClient(object):
    BASE_URL = "https://api.bitfinex.com/"
    KEY = "API_KEY_HERE"
    SECRET = "API_SECRET_HERE"
    def _nonce(self):
        # 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
        sigbytes = signature.encode(encoding='UTF-8')
        h = hmac.new(secbytes, sigbytes, hashlib.sha384)
        hexstring = h.hexdigest()
        return {
            "bfx-nonce": nonce,
            "bfx-apikey": self.KEY,
            "bfx-signature": hexstring,
            "content-type": "application/json"
        }
    def req(self, path, params = {}):
        nonce = self._nonce()
        body = params
        rawBody = json.dumps(body)
        headers = self._headers(path, nonce, rawBody)
        url = self.BASE_URL + path
        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)

为什么不使用其中一个开源API客户端？您可以与您的工作进行比较。https://github.com/scottjbarr/bitfinexhttps://github.com/tuberculo/bitfinex
