Question

我有一个WCF服务，我已经扩展了它的行为。

这是我的代码：

public object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext) {
    if (logger.IsInfoEnabled) {

        // this is a header sent from client that I need to keep so I can return it in BeforeSendReply

        var securityToken = request.Headers.GetHeader < string > (request.Headers.FindHeader("Token-ID", "SecurityInfo"))

        var bufferedCopy = request.CreateBufferedCopy(int.MaxValue);

        var sizeLog = string.Format("request message size: ~{0} KB", GetMessageLengthInKB(bufferedCopy.CreateMessage()));
        logger.Info(sizeLog);

        request = bufferedCopy.CreateMessage();
    }

    return null;
}

public void BeforeSendReply(ref Message reply, object correlationState) {
    if (logger.IsInfoEnabled) {
        // here I want to get the securityToken value ???

        var bufferedCopy = reply.CreateBufferedCopy(int.MaxValue);

        var sizeLog = string.Format("response message size: ~{0} KB", GetMessageLengthInKB(bufferedCopy.CreateMessage()));
        logger.Info(sizeLog);

        reply = bufferedCopy.CreateMessage();
    }
}

有关如何保留 securityToken 变量以便在将回复发送给客户端之前使用它的任何线索？

您可以在AfterReceiveRequest方法中返回您的令牌（而不是返回null），它将作为correlationState对象传递给BeforeSendReply（将其转换为适当的类型，您可以使用它）
