GDAX / Coinbase API身份验证过程:在散列之前必须对Unicode对象进行编码。
GDAX / Coinbase API身份验证过程:在散列之前必须对Unicode对象进行编码。
提问于 2017-12-15 02:02:02
我有很多编码经验，但是Python对我来说是个新领域。
我使用CoinbaseExchangeAuth类访问GDAX的私有端点。我写了一些简单的代码。
api_url = 'https://public.sandbox.gdax.com/'
auth = CoinbaseExchangeAuth(API_KEY, API_SECRET, API_PASS)(请注意，我已经准确地定义了api密钥，并在这些代码行之前正确传递-用于沙箱)
然后我写道：
r = requests.get(api_url + 'accounts', auth=auth)运行代码并获取以下错误：
文件"a:\PythonCryptoBot\Bot1.0\CoinbaseExhangeAuth.py"，第16行，在调用签名= hmac.new(hmackey，message，hashlib.sha256)文件"C:\Users\Dylan\AppData\Local\Programs\Python\Python35-32\lib\hmac.py"，第144行中，在新的返回HMAC(key，msg，digestmod)文件"C:\Users\Dylan\AppData\Local\Programs\Python\Python35-32\lib\hmac.py"，行84，在"C:\Users\Dylan\AppData\Local\Programs\Python\Python35-32\lib\hmac.py"，__init_ self.update(msg)文件第93行中，在update self.inner.update(msg) TypeError: Unicode对象必须在散列之前进行编码。
还请注意，我尝试过API_KEY.encode('utf-8')，并与其他人一样。-似乎什么也没做

您使用的代码是为Python2编写的，您不能期望它按原样运行。我修改了一些部件，使其与Python3兼容。
原始代码：
import json, hmac, hashlib, time, requests, base64
from requests.auth import AuthBase
# Create custom authentication for Exchange
class CoinbaseExchangeAuth(AuthBase):
def __init__(self, api_key, secret_key, passphrase):
self.api_key = api_key
self.secret_key = secret_key
self.passphrase = passphrase
def __call__(self, request):
timestamp = str(time.time())
message = timestamp + request.method + request.path_url + (request.body or '')
hmac_key = base64.b64decode(self.secret_key)
signature = hmac.new(hmac_key, message, hashlib.sha256)
signature_b64 = signature.digest().encode('base64').rstrip('\n')
request.headers.update({
'CB-ACCESS-SIGN': signature_b64,
'CB-ACCESS-TIMESTAMP': timestamp,
'CB-ACCESS-KEY': self.api_key,
'CB-ACCESS-PASSPHRASE': self.passphrase,
'Content-Type': 'application/json'
})
return request
api_url = 'https://api.gdax.com/'
auth = CoinbaseExchangeAuth(API_KEY, API_SECRET, API_PASS)
# Get accounts
r = requests.get(api_url + 'accounts', auth=auth)
print r.json()
# [{"id": "a1b2c3d4", "balance":...
# Place an order
order = {
'size': 1.0,
'price': 1.0,
'side': 'buy',
'product_id': 'BTC-USD',
}
r = requests.post(api_url + 'orders', json=order, auth=auth)
print r.json()修改后的代码：
import json, hmac, hashlib, time, requests, base64
from requests.auth import AuthBase
# Create custom authentication for Exchange
class CoinbaseExchangeAuth(AuthBase):
def __init__(self, api_key, secret_key, passphrase):
self.api_key = api_key
self.secret_key = secret_key
self.passphrase = passphrase
def __call__(self, request):
timestamp = str(time.time())
message = timestamp + request.method + request.path_url + (request.body or b'').decode()
hmac_key = base64.b64decode(self.secret_key)
signature = hmac.new(hmac_key, message.encode(), hashlib.sha256)
signature_b64 = base64.b64encode(signature.digest()).decode()
request.headers.update({
'CB-ACCESS-SIGN': signature_b64,
'CB-ACCESS-TIMESTAMP': timestamp,
'CB-ACCESS-KEY': self.api_key,
'CB-ACCESS-PASSPHRASE': self.passphrase,
'Content-Type': 'application/json'
})
return request
api_url = 'https://api.gdax.com/'
auth = CoinbaseExchangeAuth(APIKEY, API_SECRET, API_PASS)
# Get accounts
r = requests.get(api_url + 'accounts', auth=auth)
print(r.json())
# [{"id": "a1b2c3d4", "balance":...
# Place an order
order = {
'size': 1.0,
'price': 1.0,
'side': 'buy',
'product_id': 'BTC-USD',
}
r = requests.post(api_url + 'orders', json=order, auth=auth)
print(r.json())请注意，我只“翻译”了原始代码，我不能保证它的功能或安全性。

你发布的修改代码对我来说不太管用，但这确实有效！
import hmac, hashlib, time, requests, os
from requests.auth import AuthBase
API_KEY = os.environ.get('API_KEY')
API_SECRET = os.environ.get('API_SECRET')
# Create custom authentication for Coinbase API
class CoinbaseWalletAuth(AuthBase):
def __init__(self, api_key, secret_key):
self.api_key = api_key
self.secret_key = secret_key
def __call__(self, request):
timestamp = str(int(time.time()))
message = timestamp + request.method + request.path_url + (request.body or b'').decode()
signature = hmac.new(bytes(self.secret_key,'utf-8'), message.encode('utf-8'), hashlib.sha256).hexdigest()
request.headers.update({
'CB-ACCESS-SIGN': signature,
'CB-ACCESS-TIMESTAMP': timestamp,
'CB-ACCESS-KEY': self.api_key,
'CB-VERSION': '2019-11-15'
})
return request
api_url = 'https://api.coinbase.com/v2/'
auth = CoinbaseWalletAuth(API_KEY, API_SECRET)
# Get current user
r = requests.get(api_url + 'accounts', auth=auth)
