[BUG] Authorization header is not sent through swagger

It seems that swagger interface cannot send Authorization header.

I added test_auth endpoint with required header authorization like that:

async def check_auth(
        authorization: str = Header(...)
):
    pass

@router.post("/test_auth")
async def test_auth(
        auth = Depends(check_auth)
):
    pass

This works perfectly if I use REST-client with set Authorization header. But, if I use swagger UI it seems that Authorization header always missing. Server responses with status code 422 and:

  "detail": [
    {
      "loc": [
        "header",
        "authorization"
      ],
      "msg": "field required",
      "type": "value_error.missing"
    }
  ]
}

Another observation is if I change the header name to something else (not authorization) it works. But my goal is using Authorization…

Not sure if you have read: https://github.com/tiangolo/fastapi/issues/612#issuecomment-547886504

For Authorization you can use FastAPI’s HTTPBearer.

That sets the required Authorization header in the right place in OpenAPI and references it from your path operation using it.
