coinbasepro 0.1.1

功能

• 完全支持CoinBase Pro Rest API

• 干净界面的pythonic抽象

  • 返回值作为python数据类型而不是所有字符串值返回：

  >>>importcoinbaseproascbp>>>client=cbp.PublicClient()# datetime and Decimal are among the return types in the dict returned# by this call:>>>client.get_product_ticker('BTC-USD'){'trade_id':2845680,'price':Decimal('2496.69000000'),'size':Decimal('0.00100000'),'time':datetime.datetime(2019,3,20,23,53,59,596000),'bid':Decimal('2496.69'),'ask':Decimal('2496.7'),'volume':Decimal('771.51495215')}

  • 分页端点被抽象为生成器：

  >>>importitertools# get_product_trades is a generator>>>client.get_product_trades('BTC-USD')<generatorobjectPublicClient.get_product_trades.<locals>.<genexpr>at0x1098d6f68># Get 2 most recent trades. For many trade requests (>100), multiple# HTTP requests will be made under the hood.>>>list(itertools.islice(client.get_product_trades('BTC-USD'),2))[{'time':datetime.datetime(2019,3,21,0,2,45,609000),'trade_id':2845779,'price':Decimal('2463.38000000'),'size':Decimal('0.00100000'),'side':'buy'},{'time':datetime.datetime(2019,3,21,0,2,39,877000),'trade_id':2845778,'price':Decimal('2463.39000000'),'size':Decimal('0.00100000'),'side':'sell'}]

  • coinbase rest api中的疣被消除：

  # CBPro API returns raw candles from this call as tuples, which would# require user to look up value meaning in API docs. This python API# returns candles as a list of dicts, similar to other API endpoints.# Get first candle:>>>client.get_product_historic_rates('BTC-USD')[0]{'time':datetime.datetime(2019,3,21,0,6),'low':Decimal('2463.3'),'high':Decimal('2463.31'),'open':Decimal('2463.3'),'close':Decimal('2463.31'),'volume':Decimal('0.006')}

  • python api使用python3中提供的类型：

  # Example function prototype in APIdefget_product_ticker(self,product_id:str)->Dict[str,Any]:

• 允许轻松处理CoinBase错误响应的异常

>>>client.get_product_ticker(product_id='fake_product')coinbasepro.exceptions.CoinbaseAPIError:NotFound

>>>auth_client=cbp.AuthenticatedClient(key='fake',secret='fake',passphrase='fake')>>>auth_client.get_accounts()coinbasepro.exceptions.BadRequest:InvalidAPIKey

# Authenticated client using API key which doesn't have withdrawal# privileges:>>>auth_client.withdraw_to_coinbase(0.01,'BTC','fake_acct_id')coinbasepro.exceptions.InvalidAuthorization:Forbidden

# This call throws a BadRequest exception>>>auth_client.get_order('invalid_order_num')coinbasepro.exceptions.BadRequest:Invalidorderid# CoinbaseAPIError is the parent exception for all exceptions the API# throws, so catching this will catch anything>>>try:>>>auth_client.get_order('invalid_order_num')>>>exceptcbp.exceptions.CoinbaseAPIErrorase:>>>print('Caught error: {}'.format(e))Caughterror:Invalidorderid
