如何获得基本比率通用报价 (python 3.x) (Interactive Broker)

Question

基于以下网站，我想通过 reqMktData "233,236,258" 下载基本比率通用报价

https://interactivebrokers.github.io/tws-api/fundamental_ratios_tags.html

但是，我尝试了很多次，错误无法纠正。

'错误读取请求：消息 id 1004。无法解析数据。 java.lang.NumberFormatException：对于输入字符串：“快照”']

AttributeError: 'IBWrapper' 对象没有属性 'reqMktData'

备注：“IBWrapper”并非由IB官网提供，由以下链接提供： https://github.com/anthonyng2/ib

经过认真研究，IBWrapper不支持通用tick数据，只能导入ibpy。

from ib.ext.Contract import Contract
from ib.opt import ibConnection
from time import sleep
import csv

class Downloader(object):
    tickType47value = ''
    #field4price = ''

    def __init__(self):
        self.tws = ibConnection('localhost', 7496, 20)
        self.tws.register(self.tickPriceHandler, 'TickString')
        self.tws.connect()
        self._reqId = 1003 # current request id

    def tickPriceHandler(self,msg):
        if msg.tickType == 47:    # tickType=47 
            self.tickType47value = msg.value
            #print('[debug]', msg)

    def requestData(self,contract): 
        self.tws.reqMktData(self._reqId, contract, "233, 236, 258", False)  #"233, 236, 258", 
        self._reqId+=1  

    def cancelData(self):    
        #self.tws.cancelMktData(1003)
        self.tws.disconnect()
