πŸ”§ Technical Implementation

DDoS Protection Bypass Logic

Playwright Implementation

# Initialize headless Chrome
playwright_instance = sync_playwright().start()
browser = playwright_instance.chromium.launch(headless=True)
context = browser.new_context(
    user_agent='Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7)...',
    viewport={'width': 1920, 'height': 1080}
)
 
# Wait for DDoS-Guard challenge completion
page.goto(url, wait_until='domcontentloaded', timeout=60000)
page.wait_for_timeout(1000)
 
# Poll for JSON response (challenge completed)
while time.time() - start_time < 30:
    text = page.evaluate("() => document.body.textContent")
    if text.strip().startswith('{') and 'DDoS-Guard' not in text:
        break  # Challenge passed
    page.wait_for_timeout(500)

Fallback Strategy

try:
    from playwright.sync_api import sync_playwright
    USE_PLAYWRIGHT = True
except ImportError:
    try:
        from curl_cffi import requests
        USE_CURL_CFFI = True
    except ImportError:
        import cloudscraper
        USE_CLOUDSCRAPER = True

Resume Download Logic

# Check existing file size
file_size = os.path.getsize(destination) if exists else 0
 
# Add Range header for resume
headers = {'Range': f'bytes={file_size}-'} if file_size > 0 else {}
 
# Handle 206 Partial Content response
if response.status_code == 206:
    # Resume download
    file_mode = 'ab'  # Append binary
    total_size = file_size + int(response.headers['content-length'])
elif response.status_code == 200:
    # Server doesn't support resume, start fresh
    os.remove(destination)
    file_mode = 'wb'  # Write binary
    total_size = int(response.headers['content-length'])

Episode Range Parsing

# Smart parsing with validation
episode_range = input("Enter Range of Episodes: ")
 
if episode_range == '' or episode_range.lower() == 'all':
    episode_range = [1, total_episodes]
else:
    episode_range = episode_range.split('-')
    episode_range = (
        [int(episode_range[0]), int(episode_range[1])]
        if len(episode_range) == 2
        else [int(episode_range[0]), int(episode_range[0])]
    )
 
# Validation
if episode_range[0] < 1 or episode_range[1] > total_episodes:
    print("Episode range exceeds total. Select valid range.")

3. Multiple Quality Archive

Scenario: Create anime library with multiple qualities

Workflow:

# Download 1080p for personal viewing
Run 1: Quality 1080p β†’ ~/Videos/Anime/Title/
 
# Download 720p for mobile devices
Run 2: Quality 720p β†’ ~/Videos/Anime/Title_720p/

Run 3: Quality 480p β†’ ~/Videos/Anime/Title_480p/

Result: Complete library with quality options

4. Recovering Failed Downloads

Scenario: Internet connection interrupted during download

Workflow:

# First attempt - interrupted at episode 5
$ python main.py
# Downloads episode 1-4, fails at 5
 
# Resume - continues from episode 5
$ python main.py
# Select same options
# Episode 5 resumes from last byte
# Episodes 6-12 download normally

Result: Complete series despite interruptions


βš™οΈ Configuration

Updating Base URL

AnimePahe occasionally changes domains. Update in pahe.py:

# Current URL (as of 2024)
url = "https://animepahe.si/"
 
# If site moves, update to new domain
# url = "https://animepahe.com/"  # Example
# url = "https://animepahe.ru/"   # Example

Customizing Download Behavior

Concurrent Workers

# In pahe.py, adjust ThreadPoolExecutor workers
with ThreadPoolExecutor(max_workers=5) as executor:
    # Increase to 10 for faster link fetching (if bandwidth allows)
    # Decrease to 3 for slower connections

Retry Configuration

# In download_file() function
max_retries = 5  # Increase for unreliable connections
wait_time = min(2 ** retry_count, 60)  # Exponential backoff

Timeout Settings

# Connect and read timeouts
timeout=(30, 300)  # (connect_timeout, read_timeout)
# Adjust based on connection speed

πŸ› Troubleshooting

Common Issues

Issue 1: "No anime found"

Solution:
1. Check spelling of anime title
2. Try alternative spellings (e.g., "HunterxHunter" vs "Hunter x Hunter")
3. Search by English title if Japanese fails
4. Check if AnimePahe.si is accessible in your region

Issue 2: DDoS-Guard blocking access

Solution:
1. Install Playwright: pip install playwright && playwright install chromium
2. If Playwright fails, install curl_cffi: pip install curl_cffi
3. As last resort, use VPN to change IP address
4. Wait 5-10 minutes and retry

Issue 3: Download fails or stops

Solution:
1. Check internet connection stability
2. Run script again - it will auto-resume
3. If 416 error persists, delete partial file and restart
4. Try lower quality (server may throttle high-quality downloads)

Issue 4: "Episode range exceeds total"

Solution:
1. Check actual episode count displayed
2. For sequels, use correct season (e.g., Season 2 might be separate entry)
3. Some anime have different numbering on AnimePahe
4. Use 'all' to download available episodes

Issue 5: Base URL changed

Solution:
1. Visit AnimePahe's social media for new domain
2. Update url variable in pahe.py
3. Common alternatives: .com, .ru, .org, .tv
4. Check GitHub issues for latest working URL
