如何在Python中发送编码的quickfix消息？

Question

我想发送以EUC-KR编码的消息。

因此，我尝试使用下面的示例/示例发送消息，但最终出现错误。

https://github.com/fvmt/quickfix-python-sample

def put_order（self）：print（“创建以下订单：”）

trade = fix.Message() 
trade.getHeader().setField(fix.BeginString(fix.BeginString_FIX42)) # 
trade.getHeader().setField(fix.MsgType(fix.MsgType_NewOrderSingle)) #39=D 
trade.setField(fix.ClOrdID(self.genExecID())) #11=Unique order 

test_msg = '한글테스트' 

trade.getHeader().setField(fix.MessageEncoding('EUC-KR'))  # MessageEncoding
trade.setField(fix.EncodedTextLen(len(test_msg.encode('euc-kr'))))
trade.setField(fix.EncodedText(test_msg.encode('euc-kr')))

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))
trade.setField(fix.TransactTime(int(datetime.utcnow().strftime("%s")))) 

print (trade.toString() )
fix.Session.sendToTarget(trade, self.sessionID) 

我收到以下错误消息

Your Input : Successful Logon to session 'FIX.4.3:CLIENT1->EXECUTOR'.

this = _quickfix.new_StringField(*args)
NotImplementedError: Wrong number or type of arguments for overloaded function 'new_StringField'.
Possible C/C++ prototypes are:

我怎么解决这个问题？
