基于Python+BeautifulSoup爬取Brickz.my房产交易数据的技术问询
Hey there! Let me break down a practical approach to your brickz.my scraping project based on what you’ve shared:
Why BeautifulSoup Was the Right Call
Great choice going with BeautifulSoup here—brickz.my’s consistent property URL structure lets you skip the heavy browser emulation that Selenium requires. This makes your scraper faster, lighter, and easier to maintain when building out a large transaction database.
Bypassing the Login Wall for Full Transaction History
The biggest roadblock you’ve hit is the login restriction: without being logged in, you only get the latest 10 transactions per property. To unlock the full dataset, you’ll need to simulate an authenticated session using requests (paired with BeautifulSoup). Here’s how to pull it off:
Step 1: Set Up a Logged-In Session
First, you need to send a POST request to the site’s login endpoint with your credentials, and preserve the session cookies that confirm you’re authenticated. Most sites use a CSRF token to prevent form abuse, so you’ll need to grab that first from the login page.
Example code snippet:
import requests from bs4 import BeautifulSoup import time # Initialize a session to persist login cookies session = requests.Session() # Spoof a real user agent to avoid bot detection session.headers.update({ "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/116.0.0.0 Safari/537.36" }) # Grab the login page to extract the CSRF token login_page = session.get("https://www.brickz.my/login") login_soup = BeautifulSoup(login_page.content, "html.parser") csrf_token = login_soup.find("input", {"name": "_token"}).get("value") # Send login credentials (replace with your actual details) login_payload = { "email": "your_login_email@example.com", "password": "your_login_password", "_token": csrf_token } # Submit the login request login_response = session.post("https://www.brickz.my/login", data=login_payload) # Verify login success (adjust check based on site's post-login content) if "Dashboard" in login_response.text: print("Login successful! Ready to scrape full transaction history.") else: print("Login failed—double-check credentials or CSRF token extraction.")
Step 2: Scrape Full Transactions for Each Property
Once your session is authenticated, you can request property pages just like you did before—but now the server will return all available transactions instead of just the latest 10.
Example of extracting transactions:
# Example property URL (swap with your target property links) property_url = "https://www.brickz.my/property/your-target-property" # Fetch the property page using the logged-in session property_page = session.get(property_url) property_soup = BeautifulSoup(property_page.content, "html.parser") # Extract transaction data (adjust selectors to match the site's actual HTML) transaction_table = property_soup.find("table", class_="transaction-table") transaction_rows = transaction_table.find_all("tr")[1:] # Skip header row full_transactions = [] for row in transaction_rows: cols = row.find_all("td") transaction = { "transaction_date": cols[0].text.strip(), "price": cols[1].text.strip(), "property_type": cols[2].text.strip(), "size_sqft": cols[3].text.strip() # Add more fields based on what the table includes } full_transactions.append(transaction) print(f"Successfully fetched {len(full_transactions)} transactions for this property.")
Critical Tips to Avoid Getting Blocked
- Add delays: Insert
time.sleep(1-2)between requests to mimic human browsing speed. - Respect rate limits: Don’t flood the site with requests—stick to a reasonable pace.
- Check robots.txt: Review

Final Notes for Building Your Database
- Link property metadata (location, size, tenure) with transaction records for easier analysis.
- Handle pagination if transactions span multiple pages (even logged in)—look for "Next" buttons in the HTML and follow those URLs with your authenticated session.
