How to log a chat conversation with Bot Framework

问题:

I would like to log my bot conversations (to a text file or DB). I want to capture all of the input and output from the bot, including any text generated by FormFlow, Confirms, etc. I don't need the graphical elements like cards, but it would be nice to have the text from them too.

It doesn't seem practical to add logging statements after each input/output in my app, particularly since I can't easily tell exactly what text was sent to the user by FormFlow.

What's the best way to do this?

回答1:

You can log all messages (from bot or from user) using Middleware.

For C# version you must implement the IActivityLogger and log what you want in the LogAsync method.

For Example:

public class DebugActivityLogger : IActivityLogger
{
    public async Task LogAsync(IActivity activity)
    {
        Debug.WriteLine($"From:{activity.From.Id} - To:{activity.Recipient.Id} - Message:{activity.AsMessageActivity()?.Text}");
    }
}

Finally, you must register in AutoFact with something like this (in global.asax):

var builder = new ContainerBuilder();
builder.RegisterType<DebugActivityLogger>().AsImplementedInterfaces().InstancePerDependency();
builder.Update(Conversation.Container);

If you're using the nodejs version, its more straightforward:

const logUserConversation = (event) => { console.log('message: ' + event.text + ', user: ' + event.address.user.name);
};
// Middleware for logging
bot.use({
    receive: function (event, next) {
        logUserConversation(event);
        next();
    },
    send: function (event, next) {
        logUserConversation(event);
        next();
    }
});

Figured it out. I can use the Microsoft.Bot.Builder.History.IActivityLogger Interface
