Basic Fetch (Most Common) ```python from scrapling.fetchers import Fetcher page = Fetcher.get('https://example.com') # Extract content title = page.css('h1::text').get() paragraphs = page.css('p::text').getall() ``` ### 2. Stealthy Fetch (Anti-Bot/Cloudflare) ```python from scrapling.fetchers import StealthyFetcher StealthyFetcher.adaptive = True page = StealthyFetcher.fetch('https://example.com', headless=True, solve_cloudflare=True) ``` ### 3. Dynamic Fetch (Full Browser Automation) ```python from scrapling.fetchers import DynamicFetcher page = DynamicFetcher.fetch('https://example.com', headless=True, network_idle=True) ``` ### 4. Adaptive Parsing (Survives Design Changes) ```python from scrapling.fetchers import Fetcher page = Fetcher.get('https://example.com') # First scrape - saves selectors items = page.css('.product', auto_save=True) # Later - if site changes, use adaptive=True to relocate items = page.css('.product', adaptive=True) ``` ### 5. Spider (Multiple Pages) ```python from scrapling.spiders import Spider, Response class MySpider(Spider): name = "demo" start_urls = ["https://example.com"] concurrent_requests = 3 async def parse(self, response: Response): for item in response.css('.item'): yield {"item": item.css('h2::text').get()} # Follow links next_page = response.css('.next a') if next_page: yield response.follow(next_page[0].attrib['href']) MySpider().start() ``` ### 6. CLI Usage ```bash # Simple fetch to file scrapling extract get https://example.com content.html # Stealthy fetch (bypass anti-bot) scrapling extract stealthy-fetch https://example.com content.html # Interactive shell scrapling shell https://example.com ``` --- ## Common Patterns ### Extract Article Content ```python from scrapling.fetchers import Fetcher page = Fetcher.get('https://example.com/article') # Try multiple selectors for title title = ( page.css('[itemprop="headline"]::text').get() or page.css('article h1::text').get() or page.css('h1::text').get() ) # Get paragraphs content = page.css('article p::text, .article-body p::text').getall() print(f"Title: {title}") print(f"Paragraphs: {len(content)}") ``` ### Research Multiple Pages ```python from scrapling.spiders import Spider, Response class ResearchSpider(Spider): name = "research" start_urls = ["https://news.ycombinator.com"] concurrent_requests = 5 async def parse(self, response: Response): for item in response.css('.titleline a::text').getall()[:10]: yield {"title": item, "source": "HN"} more = response.css('.morelink::attr(href)').get() if more: yield response.follow(more) ResearchSpider().start() ``` ### Crawl Entire Site (Easy Mode) Auto-crawl all pages on a domain by following internal links: ```python from scrapling.spiders import Spider, Response from urllib.parse import urljoin, urlparse class EasyCrawl(Spider): """Auto-crawl all pages on a domain.""" name = "easy_crawl" start_urls = ["https://example.com"] concurrent_requests = 3 def __init__(self): super().__init__() self.visited = set() async def parse(self, response: Response): # Extract content yield { 'url': response.url, 'title': response.css('title::text').get(), 'h1': response.css('h1::text').get(), } # Follow internal links (limit to 50 pages) if len(self.visited) >= 50: return self.visited.add(response.url) links = response.css('a::attr(href)').getall()[:20] for link in links: full_url = urljoin(response.url, link) if full_url not in self.visited: yield response.follow(full_url) # Usage result = EasyCrawl() result.start() ``` ### Sitemap Crawl Crawl pages from `sitemap.xml` (with fallback to link discovery): ```python from scrapling.fetchers import Fetcher from scrapling.spiders import Spider, Response from urllib.parse import urljoin, urlparse import re def get_sitemap_urls(url: str, max_urls: int = 100) -> list: """Extract URLs from sitemap.xml - also checks robots.txt.""" parsed = urlparse(url) base_url = f"{parsed.scheme}://{parsed.netloc}" sitemap_urls = [ f"{base_url}/sitemap.xml", f"{base_url}/sitemap-index.xml", f"{base_url}/sitemap_index.xml", f"{base_url}/sitemap-news.xml", ] all_urls = [] # First check robots.txt for sitemap URL try: robots = Fetcher.get(f"{base_url}/robots.txt") if robots.status == 200: sitemap_in_robots = re.findall(r'Sitemap:\s*(\S+)', robots.text, re.IGNORECASE) for sm in sitemap_in_robots: sitemap_urls.insert(0, sm) except: pass # Try each sitemap location for sitemap_url in sitemap_urls: try: page = Fetcher.get(sitemap_url, timeout=10) if page.status != 200: continue text = page.text # Check if it's XML if '<?xml' in text or '<urlset' in text or '<sitemapindex' in text: urls = re.findall(r'<loc>([^<]+)</loc>', text) all_urls.extend(urls[:max_urls]) print(f"Found {len(urls)} URLs in {sitemap_url}") except: continue return list(set(all_urls))[:max_urls] def crawl_from_sitemap(domain_url: str, max_pages: int = 50): """Crawl pages from sitemap.""" print(f"Fetching sitemap for {domain_url}...") urls = get_sitemap_urls(domain_url) if not urls: print("No sitemap found. Use EasyCrawl instead!") return [] print(f"Found {len(urls)} URLs, crawling first {max_pages}...") results = [] for url in urls[:max_pages]: try: page = Fetcher.get(url, timeout=10) results.append({ 'url': url, 'status': page.status, 'title': page.css('title::text').get(), }) except Exception as e: results.append({'url': url, 'error': str(e)[:50]}) return results # Usage print("=== Sitemap Crawl ===") results = crawl_from_sitemap('https://example.com', max_pages=10) for r in results[:3]: print(f" {r.get('title', r.get('error', 'N/A'))}") # Alternative: Easy crawl all links print("\n=== Easy Crawl (Link Discovery) ===") result = EasyCrawl(start_urls=["https://example.com"], max_pages=10).start() print(f"Crawled {len(result.items)} pages") ``` ### Firecrawl-Style Crawl (Best of Both Worlds) Inspired by Firecrawl's behavior - combines sitemap discovery with link following: ```python from scrapling.fetchers import Fetcher from scrapling.spiders import Spider, Response from urllib.parse import urljoin, urlparse import re def firecrawl_crawl(url: str, max_pages: int = 50, use_sitemap: bool = True): """ Firecrawl-style crawling: - use_sitemap=True: Discover URLs from sitemap first (default) - use_sitemap=False: Only follow HTML links (like sitemap:"skip") Matches Firecrawl's crawl behavior. """ parsed = urlparse(url) domain = parsed.netloc # ========== Method 1: Sitemap Discovery ========== if use_sitemap: print(f"[Firecrawl] Discovering URLs from sitemap...") sitemap_urls = [ f"{url.rstrip('/')}/sitemap.xml", f"{url.rstrip('/')}/sitemap-index.xml", ] all_urls = [] # Try sitemaps for sm_url in sitemap_urls: try: page = Fetcher.get(sm_url, timeout=15) if page.status == 200: # Handle bytes text = page.body.decode('utf-8', errors='ignore') if isinstance(page.body, bytes) else str(page.body) if '<urlset' in text: urls = re.findall(r'<loc>([^<]+)</loc>', text) all_urls.extend(urls[:max_pages]) print(f"[Firecrawl] Found {len(urls)} URLs in {sm_url}") except: continue if all_urls: print(f"[Firecrawl] Total: {len(all_urls)} URLs from sitemap") # Crawl discovered URLs results = [] for page_url in all_urls[:max_pages]: try: page = Fetcher.get(page_url, timeout=15) results.append({ 'url': page_url, 'status': page.status, 'title': page.css('title::text').get() if page.status == 200 else None, }) except Exception as e: results.append({'url': page_url, 'error': str(e)[:50]}) return results # ========== Method 2: Link Discovery (sitemap: skip) ========== print(f"[Firecrawl] Sitemap skip - using link discovery...") class LinkCrawl(Spider): name = "firecrawl_link" start_urls = [url] concurrent_requests = 3 def __init__(self): super().__init__() self.visited = set() self.domain = domain self.results = [] async def parse(self, response: Response): if len(self.results) >= max_pages: return self.results.append({ 'url': response.url, 'status': response.status, 'title': response.css('title::text').get(), }) # Follow internal links links = response.css('a::attr(href)').getall()[:20] for link in links: full_url = urljoin(response.url, link) parsed_link = urlparse(full_url) if parsed_link.netloc == self.domain and full_url not in self.visited: self.visited.add(full_url) if len(self.visited) < max_pages: yield response.follow(full_url) result = LinkCrawl() result.start() return result.results # Usage print("=== Firecrawl-Style (sitemap: include) ===") results = firecrawl_crawl('https://www.cloudflare.com', max_pages=5, use_sitemap=True) print(f"Crawled: {len(results)} pages") print("\n=== Firecrawl-Style (sitemap: skip) ===") results = firecrawl_crawl('https://example.com', max_pages=5, use_sitemap=False) print(f"Crawled: {len(results)} pages") ``` ### Handle Errors ```python from scrapling.fetchers import Fetcher, StealthyFetcher try: page = Fetcher.get('https://example.com') except Exception as e: # Try stealth mode page = StealthyFetcher.fetch('https://example.com', headless=True) if page.status == 403: print("Blocked - try StealthyFetcher") elif page.status == 200: print("Success!") ``` --- ## Session Management ```python from scrapling.fetchers import FetcherSession with FetcherSession(impersonate='chrome') as session: page = session.get('https://quotes.toscrape.com/', stealthy_headers=True) quotes = page.css('.quote .text::text').getall() ``` ### Multiple Session Types in Spider ```python from scrapling.spiders import Spider, Request, Response from scrapling.fetchers import FetcherSession, AsyncStealthySession class MultiSessionSpider(Spider): name = "multi" start_urls = ["https://example.com/"] def configure_sessions(self, manager): manager.add("fast", FetcherSession(impersonate="chrome")) manager.add("stealth", AsyncStealthySession(headless=True), lazy=True) async def parse(self, response: Response): for link in response.css('a::attr(href)').getall(): if "protected" in link: yield Request(link, sid="stealth") else: yield Request(link, sid="fast", callback=self.parse) ``` --- ## Advanced Parsing & Navigation ```python from scrapling.fetchers import Fetcher page = Fetcher.get('https://quotes.toscrape.com/') # Multiple selection methods quotes = page.css('.quote') # CSS quotes = page.xpath('//div[@class="quote"]') # XPath quotes = page.find_all('div', class_='quote') # BeautifulSoup-style # Navigation first_quote = page.css('.quote')[0] author = first_quote.css('.author::text').get() parent = first_quote.parent # Find similar elements similar = first_quote.find_similar() ``` --- ## Advanced: API Reverse Engineering > "Web scraping is 80% reverse engineering." This section covers advanced techniques to discover and replicate APIs directly from websites — often revealing data that's "hidden" behind paid APIs. ### 1. API Endpoint Discovery Many websites load data via client-side requests. Use browser DevTools to find them: **Steps:** 1. Open browser DevTools (F12) 2. Go to **Network** tab 3. Reload the page 4. Look for **XHR** or **Fetch** requests 5. Check if endpoints return JSON data **What to look for:** - Requests to `/api/*` endpoints - Responses containing structured data (JSON) - Same endpoints used on both free and paid sections **Example pattern:** ``` # Found in Network tab: GET https://api.example.com/v1/users/transactions Response: {"data": [...], "pagination": {...}} ``` ### 2. JavaScript Analysis Auth tokens often generated client-side. Find them in `.js` files: **Steps:** 1. In Network tab, look at **Initiator** column 2. Click the `.js` file making the request 3. Search for auth header name (e.g., `sol-aut`, `Authorization`, `X-API-Key`) 4. Find the function generating the token **Common patterns:** - Plain text function names: `generateToken()`, `createAuthHeader()` - Obfuscated: Search for the header name directly - Random string generation: `Math.random()`, `crypto.getRandomValues()` ### 3. Replicating Discovered APIs Once you've found the endpoint and auth pattern: ```python import requests import random import string def generate_auth_token(): """Replicate discovered token generation logic.""" chars = string.ascii_letters + string.digits token = ''.join(random.choice(chars) for _ in range(40)) # Insert fixed string at random position fixed = "B9dls0fK" pos = random.randint(0, len(token)) return token[:pos] + fixed + token[pos:] def scrape_api_endpoint(url): """Hit discovered API endpoint with replicated auth.""" headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36', 'Accept': 'application/json', 'sol-aut': generate_auth_token(), # Replicate discovered header } response = requests.get(url, headers=headers) return response.json() ``` ### 4. Cloudscraper Bypass (Cloudflare) For Cloudflare-protected endpoints, use `cloudscraper`: ```bash pip install cloudscraper ``` ```python import cloudscraper def create_scraper(): """Create a cloudscraper session that bypasses Cloudflare.""" scraper = cloudscraper.create_scraper( browser={ 'browser': 'chrome', 'platform': 'windows', 'desktop': True } ) return scraper # Usage scraper = create_scraper() response = scraper.get('https://api.example.com/endpoint') data = response.json() ``` ### 5. Complete API Replication Pattern ```python import cloudscraper import random import string import json class APIReplicator: """Replicate discovered API from website.""" def __init__(self, base_url): self.base_url = base_url self.session = cloudscraper.create_scraper() def generate_token(self, pattern="random"): """Replicate discovered token generation.""" if pattern == "solscan": # 40-char random + fixed string at random position chars = string.ascii_letters + string.digits token = ''.join(random.choice(chars) for _ in range(40)) fixed = "B9dls0fK" pos = random.randint(0, len(token)) return token[:pos] + fixed + token[pos:] else: # Generic random token return ''.join(random.choices(string.ascii_letters + string.digits, k=32)) def get(self, endpoint, headers=None, auth_header=None, auth_pattern="random"): """Make API request with discovered auth.""" url = f"{self.base_url}{endpoint}" # Build headers request_headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36', 'Accept': 'application/json', } # Add discovered auth header if auth_header: request_headers[auth_header] = self.generate_token(auth_pattern) # Merge custom headers if headers: request_headers.update(headers) response = self.session.get(url, headers=request_headers) return response # Usage example api = APIReplicator("https://api.solscan.io") data = api.get( "/account/transactions", auth_header="sol-aut", auth_pattern="solscan" ) print(data) ``` ### 6. Discovery Checklist When approaching a new site: | Step | Action | Tool | |------|--------|------| | 1 | Open DevTools Network tab | F12 | | 2 | Reload page, filter by XHR/Fetch | Network filter | | 3 | Look for JSON responses | Response tab | | 4 | Check if same endpoint used for "premium" data | Compare requests | | 5 | Find auth header in JS files | Initiator column | | 6 | Extract token generation logic | JS debugger | | 7 | Replicate in Python | Replicator class | | 8 | Test against API | Run script | --- ## Brand Data Extraction (Firecrawl Alternative) Extract brand data, colors, logos, and copy from any website: ```python from scrapling.fetchers import Fetcher from urllib.parse import urljoin import re def extract_brand_data(url: str) -> dict: """Extract structured brand data from any website - Firecrawl style.""" # Try stealth mode first (handles anti-bot) try: page = Fetcher.get(url) except: from scrapling.fetchers import StealthyFetcher page = StealthyFetcher.fetch(url, headless=True) # Helper to get text from element def get_text(elements): return elements[0].text if elements else None # Helper to get attribute def get_attr(elements, attr_name): return elements[0].attrib.get(attr_name) if elements else None # Brand name (try multiple selectors) brand_name = ( get_text(page.css('[property="og:site_name"]')) or get_text(page.css('h1')) or get_text(page.css('title')) ) # Tagline tagline = ( get_text(page.css('[property="og:description"]')) or get_text(page.css('.tagline')) or get_text(page.css('.hero-text')) or get_text(page.css('header h2')) ) # Logo URL logo_url = ( get_attr(page.css('[rel="icon"]'), 'href') or get_attr(page.css('[rel="apple-touch-icon"]'), 'href') or get_attr(page.css('.logo img'), 'src') ) if logo_url and not logo_url.startswith('http'): logo_url = urljoin(url, logo_url) # Favicon favicon = get_attr(page.css('[rel="icon"]'), 'href') favicon_url = urljoin(url, favicon) if favicon else None # OG Image og_image = get_attr(page.css('[property="og:image"]'), 'content') og_image_url = urljoin(url, og_image) if og_image else None # Screenshot (using external service) screenshot_url = f"https://image.thum.io/get/width/1200/crop/800/{url}" # Description description = ( get_text(page.css('[property="og:description"]')) or get_attr(page.css('[name="description"]'), 'content') ) # CTA text cta_text = ( get_text(page.css('a[href*="signup"]')) or get_text(page.css('.cta')) or get_text(page.css('[class*="button"]')) ) # Social links social_links = {} for platform in ['twitter', 'facebook', 'instagram', 'linkedin', 'youtube', 'github']: link = get_attr(page.css(f'a[href*="{platform}"]'), 'href') if link: social_links[platform] = link # Features (from feature grid/cards) features = [] feature_cards = page.css('[class*="feature"], .feature-card, .benefit-item') for card in feature_cards[:6]: feature_text = get_text(card.css('h3, h4, p')) if feature_text: features.append(feature_text.strip()) return { 'brandName': brand_name, 'tagline': tagline, 'description': description, 'features': features, 'logoUrl': logo_url, 'faviconUrl': favicon_url, 'ctaText': cta_text, 'socialLinks': social_links, 'screenshotUrl': screenshot_url, 'ogImageUrl': og_image_url } # Usage brand_data = extract_brand_data('https://example.com') print(brand_data) ``` --- ### Brand Data CLI ```bash # Extract brand data using the Python function above python3 -c " import json import sys sys.path.insert(0, '/path/to/skill') from brand_extraction import extract_brand_data data = extract_brand_data('$URL') print(json.dumps(data, indent=2)) " ``` --- ## Feature Comparison | Feature | Status | Notes | |---------|--------|-------| | Basic fetch | ✅ Working | Fetcher.get() | | Stealthy fetch | ✅ Working | StealthyFetcher.fetch() | | Dynamic fetch | ✅ Working | DynamicFetcher.fetch() | | Adaptive parsing | ✅ Working | auto_save + adaptive | | Spider crawling | ✅ Working | async def parse() | | CSS selectors | ✅ Working | .css() | | XPath | ✅ Working | .xpath() | | Session management | ✅ Working | FetcherSession, StealthySession | | Proxy rotation | ✅ Working | ProxyRotator class | | CLI tools | ✅ Working | scrapling extract | | Brand data extraction | ✅ Working | extract_brand_data() | | API reverse engineering | ✅ Working | APIReplicator class | | Cloudscraper bypass | ✅ Working | cloudscraper integration | | Easy site crawl | ✅ Working | EasyCrawl class | | Sitemap crawl | ✅ Working | get_sitemap_urls() | | MCP server | ❌ Excluded | Not needed | --- ## Examples Tested ### IEEE Spectrum ```python page = Fetcher.get('https://spectrum.ieee.org/...') title = page.css('h1::text').get() content = page.css('article p::text').getall() ``` ✅ Works ### Hacker News ```python page = Fetcher.get('https://news.ycombinator.com') stories = page.css('.titleline a::text').getall() ``` ✅ Works ### Example Domain ```python page = Fetcher.get('https://example.com') title = page.css('h1::text').get() ``` ✅ Works --- ## 🔧 Quick Troubleshooting | Issue | Solution | |-------|----------| | 403/429 Blocked | Use StealthyFetcher or cloudscraper | | Cloudflare | Use StealthyFetcher or cloudscraper | | JavaScript required | Use DynamicFetcher | | Site changed | Use adaptive=True | | Paid API exposed | Use API reverse engineering | | Captcha | Cannot bypass -
