Python - 快速修复属性错误: sessionID

Question

我一直在尝试 QuickFix，但收到“AttributeError:SessionID”。老实说，我不知道为什么会发生这种情况，我对代码做了一些修改，但问题仍然存在。另外，谷歌在这方面让我很失望，所以我希望你们能帮助我。

代码:

import sys
import time
import thread
import argparse
from datetime import datetime
import quickfix as fix

class Application(fix.Application):
    orderID = 0
    execID = 0
    def gen_ord_id(self):
        global orderID
        orderID+=1
        return orderID


    def onCreate(self, sessionID):
            return
    def onLogon(self, sessionID):
            self.sessionID = sessionID
            print ("Successful Logon to session '%s'." % sessionID.toString())
            return

    def onLogout(self, sessionID): return

    def toAdmin(self, sessionID, message):
        return

    def fromAdmin(self, sessionID, message):
        return


    def toApp(self, sessionID, message):
        print "Sent the following message: %s" % message.toString()
        return

    def fromApp(self, message, sessionID):
        print "Received the following message: %s" % message.toString()
        return

    def genOrderID(self):
        self.orderID = self.orderID+1
        return `self.orderID`

    def genExecID(self):
        self.execID = self.execID+1
        return `self.execID`
    def put_order(self):
        print("Creating the following order: ")
        trade = fix.Message()
        trade.getHeader().setField(fix.BeginString(fix.BeginString_FIX50)) #
        trade.getHeader().setField(fix.MsgType(fix.MsgType_NewOrderSingle)) #39=D
        trade.setField(fix.ClOrdID(self.genExecID())) #11=Unique order

        trade.setField(fix.HandlInst(fix.HandlInst_MANUAL_ORDER_BEST_EXECUTION)) #21=3 (Manual order, best executiona)
        trade.setField(fix.Symbol('SMBL')) #55=SMBL ?
        trade.setField(fix.Side(fix.Side_BUY)) #43=1 Buy
        trade.setField(fix.OrdType(fix.OrdType_LIMIT)) #40=2 Limit order
        trade.setField(fix.OrderQty(100)) #38=100
        trade.setField(fix.Price(10))
        print trade.toString()
        fix.Session.sendToTarget(trade, self.sessionID)


def main(config_file):
    try:
        settings = fix.SessionSettings("initiatorsettings.cfg")
        application = Application()
        storeFactory = fix.FileStoreFactory(settings)
        logFactory = fix.FileLogFactory(settings)
        initiator = fix.SocketInitiator(application, storeFactory, settings, logFactory)
        initiator.start()

        while 1:
                input = raw_input()
                if input == '1':
                    print "Putin Order"
                    application.put_order()
                if input == '2':
                    sys.exit(0)
                if input == 'd':
                    import pdb
                    pdb.set_trace()
                else:
                    print "Valid input is 1 for order, 2 for exit"
                    continue
    except (fix.ConfigError, fix.RuntimeError), e:
        print e

if __name__=='__main__':
    parser = argparse.ArgumentParser(description='FIX Client')
    parser.add_argument('file_name', type=str, help='Name of configuration file')
    args = parser.parse_args()
    main(args.file_name)

我收到以下错误消息:

Traceback (most recent call last):

尝试完全切断这条线self.sessionID = sessionID

编辑——好的，感谢您提供回溯。您应该替换行 fix.Session.sendToTarget(trade, self.sessionID)线路 fix.Session_sendToTarget(trade)让我知道进展如何。
