Join a team using QR code sample

This sample demos a feature where user can join a team using QR code having team id.

User can generate a new QR code (contains team id information) and then scan the QR code to join the team.

Currently, Microsoft Teams support for QR or barcode scanner capability is only supported for mobile clients

Interaction with app

Prerequisites

• Microsoft Teams is installed and you have an account (not a guest account)
• NodeJS
• ngrok or equivalent tunneling solution
• M365 developer account or access to a Teams account with the appropriate permissions to install an app.

Setup

Note these instructions are for running the sample on your local machine, the tunnelling solution is required because the Teams service needs to call into the bot.

Setup for Bot SSO

a) In Azure portal, create a Azure Bot resource..

• Ensure that you've enabled the Teams Channel

b) Navigate to API Permissions, and make sure to add the follow permissions:

• Select Add a permission

• Select Microsoft Graph -> Delegated permissions.

  • User.Read (enabled by default)
  • Directory.AccessAsUser.All
  • TeamMember.ReadWrite.All

• Click on Add permissions.

Code setup

1. Clone the repository

   git clone https://github.com/OfficeDev/Microsoft-Teams-Samples.git

2. In a terminal, navigate to samples/bot-join-team-using-qr-code/nodejs

3. Install node modules

   Inside node js folder, open your local terminal and run the below command to install node modules. You can do the same in Visual Studio code terminal by opening the project in Visual Studio code.

   npm install

4. Run ngrok - point to port 3978

   ngrok http -host-header=rewrite 3978

5. Open the .env configuration file in your project folder (or in Visual Studio Code) and update the following details:

• MicrosoftAppId - It is the AppId created in previous step (Setup for Bot SSO)
• MicrosoftAppPassword - It is referred to as the "client secret" in step 1.a (Setup for Bot SSO) and you can always create a new client secret anytime
• ConnectionName - Generated from Step 1.a, is the name that we provide while adding OAuth connection setting in Azure Bot resource. Please follow Add authentication to bot to configure the connection.
• BaseUrl with application base url. For example your ngrok url like https://12123xxxx.ngrok.io.

6. Run your app

   npm start

Manually update the manifest.json

• Edit the manifest.json contained in the appPackage/ folder to replace with your MicrosoftAppId (that was created in previous step while doing AAD app registration and is the same value of MicrosoftAppId in .env file) everywhere you see the place holder string {{Microsoft-App-Id}} (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json)

• Also, update {{domain-name}} in your manifest validDomains section with your app domain like ngrok domain 1234.ngrok.io excluding http/https.

• Zip up the contents of the appPackage/ folder to create a manifest.zip

• Upload the manifest.zip to Teams (in the left-bottom Apps view, click "Upload a custom app")

IMPORTANT: The manifest file in this app adds "token.botframework.com" to the list of validDomains. This must be included in any bot that uses the Bot Framework OAuth flow.

Running the sample

• Type a message to get a card to generate the QR code.

• Select the team from dropdown list for which you want to generate the QR code and then click on 'Generate QR' button.

• Scan the generated QR code to join the team.

Deploy the bot to Azure

To learn more about deploying a bot to Azure, see Deploy your bot to Azure for a complete list of deployment instructions.
