QuickFIX/n：查询组时FieldNotFoundException

Question

我目前正在使用 QuickFIX/n 来构建接受器服务，并且我已经构建了一个启动器来测试接受器。我怀疑我得到的错误是由于接受器中的一个错误，因为同样的错误发生在其他人发送给服务的消息中。

在启动器中，我构建并发送了一个 AllocationInstruction，如下所示：

var fix44Message = new QuickFix.FIX44.AllocationInstruction(
    new AllocID(request.Info.AllocationID), EnumHelpers.ParseAllocationTransactionType(request.Info.AllocationTransactionType), EnumHelpers.ParseAllocationType(request.Info.AllocationType),
    new AllocNoOrdersType(AllocNoOrdersType.EXPLICIT_LIST_PROVIDED), EnumHelpers.ParseSide(request.Info.Side), new Symbol(request.Info.Symbol), new Quantity(request.Info.Quantity),
    new AvgPx(request.Info.AveragePrice), new TradeDate(request.Info.TradeDate.ToString("yyyyMMdd")))
    {
        SecurityID = new SecurityID(request.Info.SecurityID),
        SecurityIDSource = new SecurityIDSource(request.Info.SecurityIDSource),
        SecurityExchange = new SecurityExchange(request.Info.SecurityExchange),
        Issuer = new Issuer(request.Info.Issuer),
        Currency = new Currency(request.Info.Currency),
        TransactTime = new TransactTime(request.Info.TransactTime),
        SettlDate = new SettlDate(request.Info.SettlementDate.ToString("yyyyMMdd")),
        GrossTradeAmt = new GrossTradeAmt(request.Info.GrossTradeAmount),
        NetMoney = new NetMoney(request.Info.NetMoney)
    };

var group = new QuickFix.FIX44.AllocationInstruction.NoOrdersGroup
{
    ClOrdID = new ClOrdID(order.ClOrdID),
    OrderID = new OrderID(order.OrderID),
    OrderQty = new OrderQty(order.Quantity)
};
fix44Message.AddGroup(group);

在此特定情况下，消息是用一个订单组创建的。

在接受器中，我尝试按如下方式获取订单组：

public void OnMessage(QuickFix.FIX44.AllocationInstruction allocation, SessionID sessionID)
{
    Console.WriteLine("Order count: " + allocation.NoOrders.getValue());
    var orderGroup = new QuickFix.FIX44.AllocationInstruction.NoOrdersGroup();
    allocation.GetGroup(1, orderGroup);
    info.Orders.Add(new AllocationInstructionOrder
    {
        ClOrdID = orderGroup.ClOrdID.getValue(),
        OrderID = orderGroup.OrderID.getValue(),
        Quantity = orderGroup.OrderQty.getValue()
    });
}

allocation.NoOrders 的值如预期的那样为 1。但是，当使用索引 1（第一组）调用 GetGroup() 时，我得到

QuickFix.FieldNotFoundException occurred

最后，接受器设置：

上面的C#代码是基于example on the QuickFIX/n site.

有什么想法吗？

Answer 1

下载quickfix/n的源代码并调试后终于找到问题的原因了！

接受者没有正确解释消息，因为它没有为 NoOrders (73) 标记创建组。用于查找组标签的数据字典映射是空的，因为我在设置中使用了 UseDataDictionary=N。将接受器更改为使用数据字典解决了问题。

这是我更新的设置字符串：

SenderCompID=BAOBAB
