python - bitfinex api v2 错误，无效 key

Question

我正在尝试对他们的新 v2 api 进行基本的身份验证 api 调用并返回无效的 api key 错误。

我重新发布了 api key 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？

Answer 1

你的标题是错误的。我也在尝试这样做并尝试使用 example code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)
