How to correct POST request for registration?

Question

Python

I am trying to register on Foxford . When registering, the user packet is passed.


I pass them in the POST request, but I get a Response 422. My guess was that the data variable did not contain enough data. I decided to find all POST requests to the site, and added all the content to data.
Now the code looks terrible...

import requests
session = requests.session()

header = { 
  'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.99 Safari/537.36',
  'Content-Type':'application/x-www-form-urlencoded',
  'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
  'Accept-Language':'ru-ru,ru;q=0.8,en-us;q=0.5,en;q=0.3',
  'Accept-Encoding':'gzip, deflate',
  'Connection':'keep-alive',
  'DNT':'1'
}

print(response)

I don't understand what the problem is... I'm trying to make requests in a row, it's still 422.
Maybe I made the request incorrectly and I need to send something else? Help and do not judge strictly =)
PS. FOR THOSE WHO DO NOT UNDERSTAND THE QUESTION

import requests
session = requests.session()

header = { 
  'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.99 Safari/537.36',
  'Content-Type':'application/x-www-form-urlencoded',
  'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
  'Accept-Language':'ru-ru,ru;q=0.8,en-us;q=0.5,en;q=0.3',
  'Accept-Encoding':'gzip, deflate',
  'Connection':'keep-alive',
  'DNT':'1'
}

user = {
    'agreement': "true", 
    'email': "[email protected]",
    'first_name': "ghreeeetrge",
    'last_name': "rhgefffefeg",
    'subscribed': "true",
    'type': "pupil"
} #Даже если вместо "true" поставить True

response = session.post('https://foxford.ru/user', data=user)
print(response)

This code throws a Response 422!

Answer 1

Why do you need so many arguments, can you pass 6 arguments for registration?

Answer 2

I'm wondering why you are so prepared and write the correct headers but do not use it?
Well, in general, 422 means that the regular expression for one of the fields could not process the value, as I understand it.
It is quite possible that you end up in some left handler due to a crooked request.
