I would like to scrape a website that does not have any HTML codes in the page source using Python.
I have tried doing it with Selenium but I am trying to do it without Selenium as I have some difficulties importing this function to my Rasperry Pi.
This is something that I am interested in scraping but I can't seem to do it effectively. I have tried using bs4 and requests to work with it, but there's no HTML codes for me to work with and I can't seem to find other libraries that can do it without Selenium.
import requests
r = requests.get('https://www.cea.gov.sg/aceas/public-register/sales/1?page=1&pageSize=10&sortAscFlag=true&sort=name®istrationNumber=R')
print(r.text)
This is a simplified version of what I have tried before.

In hope that your next question(s) will contain a minimal reproducible example, here is one way to scrape that information: data is being hydrated into page dynamically, via XHR calls to an API. You can see that by inspecting Dev tools - Network tab in your browser.
import requests
import pandas as pd
from tqdm import tqdm
big_df = pd.DataFrame()
headers = {
'Origin': 'https://www.cea.gov.sg',
'Content-Type': 'application/json;charset=UTF-8',
'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.5112.79 Safari/537.36'
}
s = requests.Session()
s.headers.update(headers)
url = 'https://www.cea.gov.sg/aceas/api/internet/profile/v2/public-register/filter'
for x in tqdm(range(1, 10)):
payload = '{"page":' str(x) ',"pageSize":100,"sortAscFlag":"true","registrationNumber":"R","sort":"name","profileType":2}'
r = s.post(url, data=payload)
df = pd.json_normalize(r.json()['data'])
big_df = pd.concat([big_df, df], axis=0, ignore_index=True)
print(big_df)
This will display the datadframe in terminal:
