Example Code

from fastapi.security import OpenIdConnect

oidc = OpenIdConnect(openIdConnectUrl="http://localhost:8080/realms/tools/.well-known/openid-configuration")
app = FastAPI(swagger_ui_init_oauth = {"clientId": "docs", 
"appName": "Doc Tools", 
"usePkceWithAuthorizationCodeGrant": True, 
"scopes": "openid profile",})

@app.get("/foo")
async def bar(token = Depends(oidc)):
    return token

Description

Problem

1. Configure OpenIdConnect from fastapi.security (see code snippet)
2. got to /docs and click the authorize padlock.
3. Choose the OpenIdConnect (OAuth2, authorization_code) option
4. Successfully get redirected to your Identity providers login page (I'm using keycloak)
5. The login fails after giving correct username + password

from keycloak logs:
2022-02-20 18:46:19,516 WARN [org.keycloak.events] (executor-thread-119) type=CODE_TO_TOKEN_ERROR, realmId=tools, clientId=docs, userId=null, ipAddress=172.17.0.1, error=invalid_code, grant_type=authorization_code, code_id=d78521d2-c3ee-4b25-be91-fca0f40f6d47, client_auth_method=client-secret

Upon request inspection in brower tools, no code is actually sent.

Expected

Swagger-ui supports this login flow, so I expect it to work in fastapi docs.
