How to implement oauth to fastapi with client id & secret?

To implement OAuth in FastAPI with client ID and secret, you can use a library such as OAuthLib. Below are the steps to implement OAuth in FastAPI using OAuthLib with client ID and secret:

Step 1: Install required libraries First, install the required libraries using pip:

1

pip install oauthlib fastapi cryptography

Step 2: Define the OAuth client Create an OAuth client and store the client ID and secret in a secure way:

1

from oauthlib.oauth2 import BackendApplicationClient
from requests_oauthlib import OAuth2Session

client_id = 'your-client-id'
client_secret = 'your-client-secret'

client = BackendApplicationClient(client_id=client_id)
oauth = OAuth2Session(client=client)

Step 3: Make an OAuth token request Use the OAuth client to make a token request and obtain an access token:

1
2
3

token_url = 'https://example.com/oauth/token'  # Replace with your token URL
token = oauth.fetch_token(token_url=token_url, client_id=client_id, client_secret=client_secret)
access_token = token['access_token']

Step 4: Use the access token Now you can use the access token to authenticate requests to protected endpoints:

1

3

url = 'https://example.com/protected-endpoint'
headers = {'Authorization': f'Bearer {access_token}'}
response = oauth.get(url, headers=headers)

These are the steps to implement OAuth in FastAPI using OAuthLib with client ID and secret. Make sure to replace the placeholder values with your actual client ID, secret, token URL, and endpoint URL.
