Bot Framework v4 bot using Teams authentication.
This bot has been created using Bot Framework, it shows how to get started with authentication in a bot for Microsoft Teams.
The focus of this sample is how to use the Bot Framework support for oauth in your bot. Teams behaves slightly differently than other channels in this regard. Specifically an Invoke Activity is sent to the bot rather than the Event Activity used by other channels. This Invoke Activity must be forwarded to the dialog if the OAuthPrompt is being used. This is done by subclassing the ActivityHandler and this sample includes a reusable TeamsActivityHandler. This class is a candidate for future inclusion in the Bot Framework SDK.
The sample uses the bot authentication capabilities in Azure Bot Service, providing features to make it easier to develop a bot that authenticates users to various identity providers such as Azure AD (Azure Active Directory), GitHub, Uber, etc. The OAuth token is then used to make basic Microsoft Graph queries.
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.
This sample is a Spring Boot app and uses the Azure CLI and azure-webapp Maven plugin to deploy to Azure.
- Java 1.8+
- Install Maven
- An account on Azure if you want to deploy to Azure.
- Microsoft Teams is installed and you have an account
- ngrok or equivalent tunnelling solution
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.
-
Run ngrok - point to port 3978
ngrok http -host-header=rewrite 3978
-
Create Bot Framework registration resource in Azure
- Configure the messaging endpoint to the
https
URL you were given by ngrok and append a trailing/api/messages
- Ensure that you've enabled the Teams Channel
- If you don't have an Azure account you can use this Bot Framework registration
- Configure the messaging endpoint to the
-
Follow the instructions on this document to set up the OAuth authentication
-
Update the
resources/application.properties
configuration for the bot to use the Microsoft App Id and App Password from the Bot Framework registration. (Note the App Password is referred to as the "client secret" in the azure portal and you can always create a new client secret anytime.) -
Follow the instructions here Add Authentication to Your Bot Via Azure Bot Service to configure authentication for the bot. This is required for this sample to work correctly and prompt the user to authenticate.
-
This step is specific to Teams.
- Edit the
manifest.json
contained in theteamsAppManifest
folder to replace your Microsoft App Id (that was created when you registered your bot earlier) everywhere you see the place holder string<<YOUR-MICROSOFT-APP-ID>>
(depending on the scenario the Microsoft App Id may occur multiple times in themanifest.json
) - Zip up the contents of the
teamsAppManifest
folder to create amanifest.zip
- Upload the
manifest.zip
to Teams (in the Apps view click "Upload a custom app")
- Edit the
-
From the root of this project folder:
- Build the sample using
mvn package
- Unless done previously, install the packages in the local cache by using
mvn install
- Run it by using
java -jar .\target\bot-teams-auth-sample.jar
- Build the sample using
Note this
manifest.json
specified that the bot will be installed in a "personal" scope only. Please refer to Teams documentation for more details.
You can interact with this bot by sending it a message. The bot will respond by requesting you to login to AAD, then making a call to the Graph API on your behalf and returning the results.
When signed in, sending logout
will cause the bot to sign you out.
