bitfinex api v2错误，密钥无效

问题描述

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.

I am trying to make a basic authenticated api call to their new v2 api and getting an invalid api key error returned.

我重新发出api密钥只是为了验证，同样的错误.

I reissued the api key just to verify, same error.

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)

如何对新的bitfinex v2 API进行经过身份验证的api调用?

How do I make an authenticated api call to the new v2 API for bitfinex?

推荐答案

您的标题错误.我也在尝试这样做，并尝试使用bitfinex v2中的示例代码 api docs，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.因此，我已对其进行修复，并在下面发布了整个示例.

Your headers are wrong. I was also trying to do this and tried using the example code from the bitfinex v2 api docs, however their example contained a bug in that they needed to encode the strings into UTF-8 byte arrays first. So I've fixed it and posting the entire example below.

#
# 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)
