## Trader 交易员接口封装
## Md 行情接口封装
## struct 所有CTP结构体定义
## callback 所有CTP的回调函数名称
from pyctp import Trader, Md, struct, callback
from time import sleep
## 创建交易员接口对象
trader = Trader(frontAddress, brokerID, userID, password)
## 定义回调函数
result = []
def OnRspQryInvestor(**kwargs): # 注意：方法名称可以自由定义
result.append(kwargs)
## 绑定回调函数到交易员接口
trader.bind(callback.OnRspQryInvestor, OnRspQryInvestor)
## 准备请求数据表单
requestData = struct.CThostFtdcQryInvestorField()
requestData.BrokerID = brokerID
requestData.InvestorID = userID
## 调用请求API
trader.ReqQryInvestor(requestData)
## 等待回调被调用
while len(result) == 0:
sleep(.01)
## 查看返回数据结果
for k, v in result[0]['Data'].iteritems():
print k, ':', v
