Two almost identical codes, one works but the other doesn't

Question

I dont know why the first code works but second doesnt. After "adidas" code i gets answers "connection aborted, OSError 10054". I'v heard something about API on websites, to be honest i dont know what is it but i fell thats related :D

IT WORKS:

import requests
from bs4 import BeautifulSoup

odpowiedz = requests.get("https://www.nike.com/pl/w?q=react%20270&vst=react%20270")
soup = BeautifulSoup(odpowiedz.text, 'html.parser')

IT DOESN'T WORK:

import requests
from bs4 import BeautifulSoup

odpowiedz = requests.get("https://www.adidas.pl/search?q=ultraboost")
soup = BeautifulSoup(odpowiedz.text, 'html.parser')

Answer 1

You can use selenium instead of requests to get the page source

from selenium import webdriver
from bs4 import BeautifulSoup

driver = webdriver.Chrome()
driver.get("https://www.adidas.pl/search?q=ultraboost")
source = driver.page_source

soup = BeautifulSoup(source, 'html.parser')

If you want to exit chrome after you got the page source use driver.quit()

from selenium import webdriver
from bs4 import BeautifulSoup

driver = webdriver.Chrome()
driver.get("https://www.adidas.pl/search?q=ultraboost")
source = driver.page_source
driver.quit()

soup = BeautifulSoup(source, 'html.parser')

If you don't want the chrome tab to appear

from selenium import webdriver
from bs4 import BeautifulSoup

options = webdriver.ChromeOptions()
options.add_argument('--headless')
driver = webdriver.Chrome(options=options)
driver.get("https://www.adidas.pl/search?q=ultraboost")
source = driver.page_source
driver.quit()

soup = BeautifulSoup(source, 'html.parser')

Answer 2

Daweo is right, the Adidas server checks the User-Agent header.

This works for me:

import requests
from bs4 import BeautifulSoup

headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:74.0) Gecko/20100101 Firefox/74.0",
           #"Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
           #"Accept-Language": "en-US,en;q=0.5",
           }

odpowiedz = requests.get("https://www.adidas.pl/search?q=ultraboost", headers=headers)
soup = BeautifulSoup(odpowiedz.text, 'html.parser')

It even accepts "aaaaaaaaaaaaaadaaaMozilla" .

For Adidas.com, if you don't have an acceptable User-Agent , it returns a page explaining why:
