FastAPI: form-data name with a dot

Question

I have documentation. Form-data names have dots.

This code doesn't work:

from fastapi import FastAPI, File, UploadFile

app = FastAPI()

@app.post('/test')
async def test(anpr: UploadFile = File(...), 
               licensePlatePicture: UploadFile = File(...),
               detectionPicture: UploadFile = File(...)
              ):
    ''''''
    return None

Question: What if we have form-data name with a dot?

Hello @Chris. Thank you for your attention to my question. I do not need forms with dots)) This is the documentation for the Hikvision camera. — Alexey Golyshev, Dec 19 '22 at 12:56
define you method like this `async def test(files: list[UploadFile] = File())` then loop over your files and pick the one you want by name — aramcpp, Dec 19 '22 at 12:57
Hello @aramcpp. Thank you for your idea. But this does not work. — Alexey Golyshev, Dec 19 '22 at 13:00

You can add aliases to your file fields like this:

@app.post('/test')
async def test(anpr: UploadFile = File(..., alias='anpr.xml'),
               licensePlatePicture: UploadFile = File(..., alias='licensePlatePicture.jpg'),
               detectionPicture: UploadFile = File(..., alias='detectionPicture.jpg')
              ):
