Get Started

from typing import Annotated

from fastapi import Depends, FastAPI
from fastapi.responses import RedirectResponse

from examples.config import settings
from fastlink import GoogleSSO
from fastlink.schemas import OAuth2Callback, OpenID

app = FastAPI()

sso = GoogleSSO(
    settings.google_client_id,
    settings.google_client_secret,
    "http://localhost:8000/callback",
)


@app.get("/login")
async def login() -> RedirectResponse:
    async with sso:
        url = await sso.login_url()
        return RedirectResponse(url=url)


@app.get("/callback")
async def callback(call: Annotated[OAuth2Callback, Depends()]) -> OpenID:
    async with sso:
        return await sso.callback(call)

Now you can run the server and visit http://localhost:8000/login to start the OAuth 2.0 flow.

After logging into Google, you will be redirected to the callback URL. The server will then fetch the user's OpenID information and return it as a response.
