Python no json object could be decoded

Question

I'm trying to create a simple login into a "Kahoot!" quiz . First thing i'm trying to do is load from "https://kahoot.it/#/" JSON objects so i could fill the form in it (i tried to fill the form using 'mechenize' but its seems to support only html forms). when im running the next script im getting exception that json could not be decoded:

import urllib, json
url = "https://kahoot.it/#/"
response = urllib.urlopen(url)
data = json.loads(response.read())
print data

output:

ValueError: No JSON object could be decoded

Any ideas? , Thanks.

Answer 1

type(response.read()) is str, representing the HTML of the page. Obviously it's not a valid JSON therefore you are getting that error.

EDIT If you are trying to login to that page, it is possible with selenium:

from selenium import webdriver
url = "https://kahoot.it/#/"
driver = webdriver.Chrome() # or webdriver.Firefox()
driver.get(url)
# finding the text field and 'typing' the game pin
driver.find_element_by_xpath('//*[@id="inputSession"]').send_keys('your_game_pin')
# finding and clicking the sumbit button
driver.find_element_by_xpath('/html/body/div[3]/div/div/div/form/button').click()

• oprezyzer: so what is the right way to load json from this website?
• DeepSpace: In order to load JSON from the website, it needs to send you a response containing JSON. It doesn't seem to be the case. If you are trying to login to that page, it is possible with selenium.
• oprezyzer: Thank you, any other idea how can i get the form so i could fill it with python?
