我们目前正在使用botframework开发自动化。
在对话的某个时刻，我们通过服务总线发送了一些数据进行处理，并等待响应，然后希望继续对话。我们已经实现了在服务总线订阅中等待响应条目的部分，然后我们希望将Event类型的Activity发送到bot。
我们按照其他帖子中所述对主动消息执行了相同的步骤。 我们能够重新创建botclient和对话引用以及所有内容，但是最后，当我们发送活动时，我们总是将其发送给用户而不是机器人。但这不会触发“ EventActivityPrompt”。
达到期望结果的唯一方法是在api / messages上发布帖子，但这对于我们的口味来说太复杂了，我们正在寻找一种通过botClient（或类似技术）的更简单的方法
有人有好主意吗？ ：）
ServiceBusReceiver消息处理：

channelId?.ToString(),
data.ConversationId,
serviceUrl?.ToString());
conversationReference.User = new ChannelAccount()

await _messageReceiver.CompleteAsync(message.SystemProperties.LockToken);
// This "works" but is complicated, as we have to set up a whole HTTP call
await _offTurnConversationService.SendActivityToBotAsync(activity);
// This just sends the Event to the user, no matter how I set up the conversation
// reference regarding From/Recipient
// And it doesn't help in continuing the conversation
await _offTurnConversationService.SendToConversationThroughPipelineAsync(
async (turnContext, cancellationToken) =>
{
await turnContext.SendActivityAsync(activity, cancellationToken: cancellationToken);
},

// Note: Use the cancellationToken passed as necessary to determine if the subscriptionClient has already been closed.
// If subscriptionClient has already been closed, you can choose to not call CompleteAsync() or AbandonAsync() etc.
// to avoid unnecessary exceptions.
