How to accept data (in dictionary format) to the server?

Question

Python

I send data to the local Flask server

import requests
r = requests.post('http://127.0.0.1:5000/', data = {'key1':'value1'})

But I don’t understand how to correctly accept them, I found the form.to_dict(flat=False) method, but for some reason it distorts 'value1' if there were nested lists.

@app.route('/', methods=['GET', 'POST'])
def server_main():
    data = request.form.to_dict(flat=False)

Hence the question, how to properly receive data that is sent locally from the script to the local Flask server?

Answer 1

Complex structures must be passed in a serialized form. For example in JSON.
