Classes

ApiKeyProvider

Provider that handles API Key authentication

AppCredential

Represent Microsoft 365 tenant identity, and it is usually used when user is not involved like time-triggered automation job.

Example

ConversationBot

Provide utilities for bot conversation, including:

  • handle command and response.
  • send notification to varies targets (e.g., member, group, channel).

Example

For command and response, you can register your commands through the constructor, or use the registerCommand and registerCommands API to add commands later.

// register through constructor
const conversationBot = new ConversationBot({
  command: {
    enabled: true,
    commands: [ new HelloWorldCommandHandler() ],
  },
});

// register through `register*` API
conversationBot.command.registerCommand(new HelpCommandHandler());

For notification, you can enable notification at initialization, then send notifications at any time.

// enable through constructor
const conversationBot = new ConversationBot({
  notification: {
    enabled: true,
  },
});

// get all bot installations and send message
for (const target of await conversationBot.notification.installations()) {
  await target.sendMessage("Hello Notification");
}

// alternative - send message to all members
for (const target of await conversationBot.notification.installations()) {
  for (const member of await target.members()) {
    await member.sendMessage("Hello Notification");
  }
}

Example

When used with your bots DialogSet you can simply add a new instance of the prompt as a named dialog using DialogSet.add(). You can then start the prompt from a waterfall step using either DialogContext.beginDialog() or DialogContext.prompt(). The user will be prompted to sign in as needed and their access token will be passed as an argument to the callers next waterfall step:

const { ConversationState, MemoryStorage } = require('botbuilder');
const { DialogSet, WaterfallDialog } = require('botbuilder-dialogs');
const { TeamsBotSsoPrompt } = require('@microsoft/teamsfx');

const convoState = new ConversationState(new MemoryStorage());
const dialogState = convoState.createProperty('dialogState');
const dialogs = new DialogSet(dialogState);

dialogs.add(new TeamsBotSsoPrompt('TeamsBotSsoPrompt', {
   scopes: ["User.Read"],
}));

dialogs.add(new WaterfallDialog('taskNeedingLogin', [
     async (step) => {
         return await step.beginDialog('TeamsBotSsoPrompt');
     },
     async (step) => {
         const token = step.result;
         if (token) {

             // ... continue with task needing access token ...

         } else {
             await step.context.sendActivity(`Sorry... We couldn't log you in. Try again later.`);
             return await step.endDialog();
         }
     }
