為什么在 FIX 登錄期間連接被重置？

Question

我在針對我的 FIX 服務器測試我的 FIX 客戶端時遇到問題。 我的客戶端日志如下所示，您可以看到連接正在重置，我正在嘗試確定原因。

修復客戶端日志：

2/1/2023 2:50:32 PM inf: [FixClient] OnLogout: FIX.4.4:CLIENT->SERVER
<event> Session reset: ResetOnDisconnect

客戶：

SessionID sessionId = new SessionID("FIX.4.4", "CLIENT", "SERVER");

var logon = new QuickFix.FIX44.Logon {
    EncryptMethod = new EncryptMethod(EncryptMethod.None),
    HeartBtInt = new HeartBtInt(30)
};

Session.SendToTarget(logon, sessionId);

客戶端.cfg：

[DEFAULT]
ConnectionType=initiator
ReconnectInterval=30
FileStorePath=store
FileLogPath=log
StartTime=00:00:00
EndTime=00:00:00
UseDataDictionary=Y

SocketConnectHost=127.0.0.1
SocketConnectPort=5001
LogoutTimeout=5
ResetOnLogon=Y
ResetOnLogout=Y
ResetOnDisconnect=Y

[SESSION]
# inherit ConnectionType, ReconnectInterval and SenderCompID from default
BeginString=FIX.4.4
SenderCompID=CLIENT
TargetCompID=SERVER
HeartBtInt=30

服務器.cfg：

[DEFAULT]
ConnectionType=acceptor
SocketAcceptPort=5001
StartTime=00:00:00
EndTime=00:00:00
FileLogPath=log
UseDataDictionary=Y
ResetOnLogon=Y
ResetOnLogout=Y
ResetOnDisconnect=Y

[SESSION]
BeginString=FIX.4.4
SenderCompID=CLIENT
TargetCompID=SERVER
FileStorePath=store
DataDictionary=./FIX/spec/FIX44.xml

Answer 1

它是 CompID。

服務器和客戶端應該交換了 CompID。 服務器TargetCompID是客戶端SenderCompID ，反之亦然。
