欢迎消息 Bot Framework v4 nodejs

Question

I'm developing a multichannel bot (focusing on web and telegram) that's based on Microsoft's Bot Framework ( https://docs.microsoft.com/en-us/azure/bot-service/?view=azure-bot-service-4.0 )

I'm stuck with the initial message the user is getting. My bot is based on the complex bot published by Microsoft: https://github.com/Microsoft/BotFramework-Samples/tree/master/SDKV4-Samples/js/complexDialogBot

Issue I'm seeing is that in the emulator bot is working great, on the web user is not greeted with the welcome message. I've used iframe to integrate the bot.

I'm checking activity types and when members are added to the chat, but seems like it's not triggering on the web.

if (turnContext.activity.type === ActivityTypes.ConversationUpdate) {
    if (turnContext.activity.membersAdded && turnContext.activity.membersAdded.length > 0) {
        await this.sendWelcomeMessage(turnContext);
    }
}

I saw similar questions asked but either for bot framework v3 or C# implementation (like this one Welcome message not visibile in Webchat,but work in Emulator and Welcome Message not working in Azure portal using Microsoft Bot Builder SDK(v4) for nodejs )

Answer 1

try using this

enter code here
         this.onMembersAdded(async context => {
        const membersAdded = context.activity.membersAdded;
        for (let cnt = 0; cnt < membersAdded.length; cnt++) {
            if (membersAdded[cnt].id == context.activity.recipient.id) {                    
                 const welcomeCard = CardFactory.adaptiveCard(WelcomeCard);
          }
        }
    });

You can solve your problem in below code in iframe to integrate the bot you can write member Adding code copy in inside !turnContext.responded
