[FIXED] TimeoutError: The read operation timed out

Issue

The Script

Here's a simple script that uses requests to download a web page:

import requests
import pandas as pd

from bs4 import BeautifulSoup

url = "https://www.cmegroup.com/markets/energy/crude-oil/light-sweet-crude.quotes.html"

data = requests.get(url).text

However, it seems to hang at the call to requests.get.

If I use the following instead:

data = requests.get(url, allow_redirects=False, timeout=5).text

it outputs the following:

Traceback (most recent call last):

Question

What's a good way to get the script to download the page as intended?

Solution

Just add relevant headers, the website seems to be blocking requests without valid headers:

import requests

url = 'https://www.cmegroup.com/markets/energy/crude-oil/light-sweet-crude.quotes.html'
headers = {'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9',
           'Accept-Encoding': 'gzip, deflate',
           'Accept-Language': 'en-US,en;q=0.9',
           'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36'}

print(requests.get(url, headers=headers).text)
