[QUESTION] How to work with form data?

Hello everyone! I need to process form data but I can’t do that with fastapi. To try understand how can I do it I used Postman to send data in different ways: from form-data tab from x-www-form-urlencoded with header “Content-Type: application/x-www-form-urlencoded” with header “Content-Type: application/json” without headers

In any case I have the same result: {“detail”: “There was an error parsing the body”}.

from fastapi import FastAPI, HTTPException, Form

@app.post("/subscription_email")
def subscription_email(*, customers: int = Form(...)):
    return customers

Code based on example from docs.

Please, help me to fix it and understand how to work woth form data from POST requests.

@euri10 thank you very much!!! Now it works!!! I checked logs and found reason. The reason is “python-multipart” was not installed. I was surprised because I thought that image contains any requirements for fastapi. Anyway, now I know how to check what’s wrong:) Thank you so much!!!

Ran into the same error. Quite dumb to not report the missing package.
