我如何在像messages controller这样的对话框之外访问Bot Framework ConversationData?

botframework c#

Sam Hanley · 技术社区 · 8 年前

在我的机器人内的一个对话框中,我在ConversationData中存储了一个标志值,如下所示:

context.ConversationData.SetValue("SomeFlag", true);

稍后,我需要检查MessagesController中的标志, 之前 this previous question

public async Task<HttpResponseMessage> Post([FromBody] Activity incomingMessage)
{
    StateClient stateClient = incomingMessage.GetStateClient();
    BotData userData = await stateClient.BotState.GetConversationDataAsync(message.ChannelId, message.Conversation.Id);
    bool finishedQuote = userData.GetProperty<bool>("SomeFlag");
    //...
    // do conditional logic, then dispatch to a dialog as normal
}

然而,在运行时 userData userData.Data 为null,我无法通过 GetProperty . 我什么都没看到 relevant documentation

if (activity.Type == ActivityTypes.Message)
{

    var message = activity as IMessageActivity;
    using (var scope = DialogModule.BeginLifetimeScope(Conversation.Container, message))
    {
        var botDataStore = scope.Resolve<IBotDataStore<BotData>>();
        var key = Address.FromActivity(message);

        ConversationReference r = new ConversationReference();
        var userData = await botDataStore.LoadAsync(key, BotStoreType.BotUserData, CancellationToken.None);

        //you can get/set UserData, ConversationData, or PrivateConversationData like below
        //set state data
        userData.SetProperty("key 1", "value1");
        userData.SetProperty("key 2", "value2");
        //get state data
        userData.GetProperty<string>("key 1");
        userData.GetProperty<string>("key 2");

        await botDataStore.SaveAsync(key, BotStoreType.BotUserData, userData, CancellationToken.None);
        await botDataStore.FlushAsync(key, CancellationToken.None);
    }
    await Conversation.SendAsync(activity, () => new Dialogs.RootDialog());
}

   public static T GetStateData<T>(Activity activity, string key)
    {
        BotState botState = new BotState(activity.GetStateClient());
        BotData botData = botState.GetConversationData(activity.ChannelId, activity.Conversation.Id);
        return botData.GetProperty<T>(key);
    }
