Python 3.4 Coinbase 钱包 API V2
一段时间以来,我一直试图弄清楚这个购买调用(以及其他 api 调用,如 get_payment_methods() 和 get_accounts() )是否遇到身份验证错误。我已经成功地能够在单独的文件中单独运行其中一些 api 调用。
什么不起作用:
class api_call(object):
def __init__(self):
self.CB_key = xxxxxxxx
self.CB_secret = yyyyyyyy
self.CB_account = zzzzzzzzz
self.CB_payment_method = aaaaaaaaaa
def buy_c(self, exchange, b_amount):
client = Client(self.CB_key, self.CB_secret)
buy = client.buy(self.CB_account, amount=str(b_amount), currency="USD", payment_method=self.CB_payment_method)
api = api_call()
buy = api.buy('COIN-BS', 1)
我已经三次检查了我的帐户、密钥和机密,并且还尝试在类定义中对它们进行硬编码,而不是使用init成员。
什么有效:
from coinbase.wallet.client import Client
client = Client(<api_key>, <api_secret>)
buy = client.buy('zzzzzzzz', amount='1', currency="USD", payment_method='aaaaaaaaaa')
错误如下:
Traceback (most recent call last):
File "api_call.py", line 126, in <module>
buy = api.buy('COIN-BS', 1)
File "api_call.py", line 110, in buy
buy = client.buy_c( self.CB_account, amount=str(amount), currency="USD", payment_method="XXXXXXXXXXXX")
File "/home/LA/.local/lib/python3.4/site-packages/coinbase/wallet/client.py", line 381, in buy
response = self._post('v2', 'accounts', account_id, 'buys', data=params)
File "/home/LA/.local/lib/python3.4/site-packages/coinbase/wallet/client.py", line 132, in _post
return self._request('post', *args, **kwargs)
File "/home/LA/.local/lib/python3.4/site-packages/coinbase/wallet/client.py", line 116, in _request
return self._handle_response(response)
File "/home/LA/.local/lib/python3.4/site-packages/coinbase/wallet/client.py", line 125, in _handle_response
raise build_api_error(response)
coinbase.wallet.error.AuthenticationError: APIError(id=authentication_error): invalid signature
我认为问题可能是由于在类文件的定义中使用了 API 购买方法,即我的 api_call.py 类。我认为这是因为我可以调用购买方法(和其他方法)就好了单独的文件,甚至在 api_call.py 内的类缩进之外。
有谁知道为什么这会引发身份验证错误?我在error.py中环顾四周,但还没有找到关于为什么会发生这种情况的线索。
与往常一样,非常感谢您对此事的任何帮助或想法!
编辑
在同一个文件上运行工作代码和非工作代码后,我成功地进行了两次购买。在尝试了其他一些事情之后,我发现显然任何使用这些全局修改变量、命令行参数和更新的对象成员变量的 API POST 都会产生此身份验证错误。这应该发生吗?
from coinbase.wallet.client import Client
#Globals
key = 'xxxxxx'
secret = 'yyyyyy'
account = 'zzzzzzz'
payment = 'aaaaaaa'
class api_call(object):
def __init__(self):
self.CB_key = None
self.CB_secret = None
self.CB_account = None
self.CB_payment_method = None
def buy_c(self, exchange, b_amount):
client = Client(key, secret)
buy = client.buy(account, amount=str(b_amount), currency="USD", payment_method=payment)
client = Client(key, secret)
buy = client.buy(account, amount='1', currency="USD", payment_method=payment)
api = api_call()
buy = api.buy_c('COIN-BS', 1)
