所以我正在使用 python 访问 poloniex API，这是我的代码：

from poloniex import Poloniex
import krakenex
import threading
import pprint
import urllib.request
import json
####POLONIEX####

#FUNCTIONS

polo = Poloniex()

def BTC_USDT_LAST_POLONIEX():
  polo = Poloniex()
  threading.Timer(1.0, BTC_USDT_LAST_POLONIEX).start() # called every minute
  print("BTC Last Price = " + (polo('returnTicker')['USDT_BTC']['last']))

def POLONIEX_ASSET_LIST():
    pprint.pprint(sorted(list(polo('returnTicker'))))

到目前为止一切正常，我想避免使用 urllib 作为将 http 请求转换为列表的痛苦。我正在尝试访问订单簿，但出现以下错误：

>>> polo('returnOrderBook')
Traceback (most recent call last):
  File "<pyshell#27>", line 1, in <module>
    polo('returnOrderBook')
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/poloniex/retry.py", line 15, in wrapped
    return function(*args, **kwargs)
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/poloniex/__init__.py", line 183, in __call__
    return self.parseJson(ret.text)
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/poloniex/__init__.py", line 197, in parseJson
    raise PoloniexError(jsonout['error'])
poloniex.PoloniexError: Please specify a currency pair.

我试过指定货币对，但不知道如何插入。

重写您的代码并使用requests模块而不是urllib：

import requests
ret = requests.get('http://poloniex.com/public?command=returnOrderBook&currencyPair=BTC_BCN').json()
print ret
