FastAPI

Utilities are provided to ease the integration of an OAuth2 process in FastAPI.

OAuth2AuthorizeCallback

Dependency callable to handle the authorization callback. It reads the query parameters and returns the access token and the state.

Parameters

• client: OAuth2: The OAuth2 client.
• route_name: Optional[str]: Name of the callback route, as defined in the name parameter of the route decorator.
• redirect_url: Optional[str]: Full URL to the callback route.

Tip

You should either set route_name, which will automatically reverse the URL, or redirect_url, which is an arbitrary URL you set.

from httpx_oauth.integrations.fastapi import OAuth2AuthorizeCallback
from httpx_oauth.oauth2 import OAuth2

client = OAuth2("CLIENT_ID", "CLIENT_SECRET", "AUTHORIZE_ENDPOINT", "ACCESS_TOKEN_ENDPOINT")
oauth2_authorize_callback = OAuth2AuthorizeCallback(client, "oauth-callback")
app = FastAPI()

@app.get("/oauth-callback", name="oauth-callback")
async def oauth_callback(access_token_state=Depends(oauth2_authorize_callback)):
    token, state = access_token_state
