Access user data bag from scorable without IDialogContext

问题

Dialogs have the IDialogContext object to aaccess data bags.

Example:

private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result)

How to access context.UserDataBag from scorable class global handler? It doesn't contain IDialogContext but I need user data from botDataBag in scorable class.

回答1:

The usual way of doing this is using IBotData in your scorable.

You need to modify the constructor of your IScorable so it receives an IBotData, save it in a local variable, and use it later.

private readonly IBotData botData;

public ExtractCodeScorable(IBotToUser botToUser, IBotData botData) 
{ 
    this.botData = botData
}

Then you can use it as:

this.botData.PrivateConversationData.SetValue(key, element.Value); (or any of the other databags)

You can check the demo-CardAttachments sample as it heavily uses scorables and saves data in the data bags.

You can access BotState from the Activity object. here is an example of a Scorable implementing ScorableBase and accessing UserData

public class CancelScorable : ScorableBase<IActivity, string, double>
{
    private readonly IDialogTask task;

    public CancelScorable(IDialogTask task)
    {
        SetField.NotNull(out this.task, nameof(task), task);
    }

    protected override async Task<string> PrepareAsync(IActivity activity, CancellationToken token)
    {
        // Accessing info, for example here UserData:
        var userData = await activity.GetStateClient().BotState.GetUserDataAsync(activity.ChannelId, activity.From.Id);

        // ... add your treatment

        return null;
    }

    // ...
}
