Authentication (Token check) before file upload

How can i check ouath2 token before the file is uploaded?

In the current configuration the file is uploaded and then the dependency is called to check the token. Instead of wasting resources untill the file is completely uploaded (especially if it’s a big file) I would like to check the token before it completes the upload

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def upload_file(
        user_id=Depends(verify_access_token),
        ufiles: UploadFile = File(...),
):
    return {"Hello": "World"}

Have you tried using an asynchronous function for this case ?

But does it really depend on the actual endpoint/middleware? Isn’t the file upload being the part of the request? Therefore only if the file is uploaded, the request is “complete” and sent to the server? I think that this is part of how HTTP works, not fastapi itself.
