# Authentication Bot Utilizing Microsoft Graph
|
||
|
||
Bot Framework v4 bot authentication using Microsoft Graph sample
|
||
|
||
This bot has been created using [Bot Framework](https://dev.botframework.com). It shows how to use the bot authentication capabilities of Azure Bot Service. In this sample we are assuming the OAuth 2 provider is Azure Active Directory v2 (AADv2) and are utilizing the Microsoft Graph API to retrieve data about the user. [Check here](https://docs.microsoft.com/en-us/azure/bot-service/bot-builder-authentication?view=azure-bot-service-4.0&tabs=csharp) for information about getting an AADv2
|
||
application setup for use in Azure Bot Service. The [scopes](https://developer.microsoft.com/en-us/graph/docs/concepts/permissions_reference) used in this sample are the following:
|
||
|
||
- `User.Read`
|
||
|
||
## Prerequisites
|
||
|
||
- [Node.js](https://nodejs.org) version 10.14 or higher
|
||
|
||
```bash
|
||
# determine node version
|
||
node --version
|
||
```
|
||
|
||
- Update `.env` with required configuration settings
|
||
- MicrosoftAppId
|
||
- MicrosoftAppPassword
|
||
- ConnectionName
|
||
|
||
## To try this sample
|
||
|
||
- Install modules
|
||
|
||
```bash
|
||
npm install
|
||
```
|
||
|
||
- Start the bot
|
||
|
||
```bash
|
||
npm start
|
||
```
|
||
|
||
## Testing the bot using Bot Framework Emulator
|
||
|
||
[Microsoft Bot Framework Emulator](https://github.com/microsoft/botframework-emulator) is a desktop application that allows bot developers to test and debug their bots on localhost or running remotely through a tunnel.
|
||
|
||
- Install the [Bot Framework Emulator](https://github.com/microsoft/botframework-emulator/releases)
|
||
- In Bot Framework Emulator Settings, enable `Use a sign-in verification code for OAuthCards` to receive the magic code
|
||
|
||
### Connect to bot using Bot Framework Emulator
|
||
|
||
- Launch Bot Framework Emulator
|
||
- File -> Open Bot
|
||
- Enter a Bot URL of `http://localhost:3978/api/messages
|
||
|
||
## Authentication
|
||
|
||
This sample uses the bot authentication capabilities of 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, and so on. These updates also
|
||
take steps towards an improved user experience by eliminating the magic code verification for some clients and channels.
|
||
It is important to note that the user's token does not need to be stored in the bot. When the bot needs to use or verify the user has a valid token at any point the OAuth prompt may be sent. If the token is not valid they will be prompted to login.
|
||
|
||
## Microsoft Graph API
|
||
|
||
This sample demonstrates using Azure Active Directory v2 as the OAuth2 provider and utilizes the Microsoft Graph API.
|
||
Microsoft Graph is a Microsoft developer platform that connects multiple services and devices. Initially released in 2015,
|
||
the Microsoft Graph builds on Office 365 APIs and allows developers to integrate their services with Microsoft products
|
||
including Windows, Office 365, and Azure.
|
||
|
||
## Deploy the bot to Azure
|
||
|
||
To learn more about deploying a bot to Azure, see [Deploy your bot to Azure](https://aka.ms/azuredeployment) for a complete list of deployment instructions.
|
||
|
||
## GraphError 404: ResourceNotFound, Resource could not be discovered
|
||
|
||
This error may confusingly present itself if either of the following are true:
|
||
|
||
- You're using an email ending in `@microsoft.com`, and/or
|
||
- Your OAuth AAD tenant is `microsoft.onmicrosoft.com`.
|
||
|
||
## Testing Direct Line token generation
|
||
|
||
- [Connect to Direct Line](https://docs.microsoft.com/en-us/azure/bot-service/bot-service-channel-connect-directline?view=azure-bot-service-4.0)
|
||
|
||
- Add ‘Direct Line Secret’ to `.env`
|
||
|
||
```bash
|
||
DirectLineSecret=YOUR_DIRECT_LINE_SECRET
|
||
```
|
||
|
||
- Start the bot
|
||
|
||
```bash
|
||
npm start
|
||
```
|
||
|
||
- Open [PostMan](https://www.postman.com/) and setup a post request to http://localhost:3978/directline/token
|
||
with the following json request body:
|
||
|
||
```
|
||
{
|
||
"user": "USER_ID"
|
||
}
|
||
```
|
||
|
||
Then you can see the Direct Line token generated with YOUR_DIRECT_LINE_SECRET and USER_ID:
|
||
|
||
```
|
||
{
|
||
"conversationId": "XXXXX",
|
||
"token": "XXXXX",
|
||
"expires_in": 3600
|
||
}
|
||
```
