收集、分析多維度網路指紋：

• TCP/IP協定棧特徵
• TLS握手參數
• HTTP/2連線特性
• WebRTC資訊洩露

核心防封鎖策略

1. 模擬真實用戶行為

行為模式設計：
ig真實用戶展現出：

• 不規律登入時間（非固定時段）
• 瀏覽類別多元（非只看單種內容）
• 自然互動（點讚、留言、分享）
• 合理會話時長（約15-45分鐘）

實作範例：

import random
import time

class HumanBehaviorSimulator:
    def __init__(self):
        self.session_duration = random.randint(900, 2700)  # 15-45 minutes
        self.actions_per_session = random.randint(20, 100)
        self.break_probability = 0.15  # 15% chance to pause
    
    def simulate_reading_time(self, content_type):
        """Simulate reading time for different content types"""
        base_times = {
            'post': (3, 15),      # Posts: 3-15s
            'story': (2, 8),      # Stories: 2-8s
            'profile': (5, 30),   # Profile: 5-30s
            'comments': (10, 60)  # Comments: 10-60s
        }
        min_time, max_time = base_times.get(content_type, (2, 10))
        return random.uniform(min_time, max_time)
    
    def should_take_break(self):
        """Decide whether to take a break"""
        return random.random() < self.break_probability

2. 智慧請求排程

自適應速率調控：
依據網路狀況與伺服器回應動態調整請求頻率。

class AdaptiveRateController:
    def __init__(self):
        self.base_delay = 2.0  # 2s base delay
        self.current_delay = self.base_delay
        self.success_count = 0
        self.error_count = 0
    
    def adjust_delay(self, response_time, status_code):
        """Adjust delay based on response"""
        if status_code == 200:
            self.success_count += 1
            if self.success_count > 10:
                # Accelerate after consecutive successes
                self.current_delay *= 0.95
                self.current_delay = max(self.current_delay, 1.0)
        elif status_code in [429, 503]:
            # On rate limit, greatly increase delay
            self.current_delay *= 2.0
            self.error_count += 1
        elif status_code >= 400:
            # Other errors, increase delay moderately
            self.current_delay *= 1.2
            self.error_count += 1
        
        # Add jitter
        jitter = random.uniform(0.8, 1.2)
        return self.current_delay * jitter

3. 分散式架構

多節點協作：
分散式系統分攤負載，大幅降低單一來源風險。

class DistributedCrawler:
    def __init__(self, node_count=5):
        self.nodes = []
        self.task_queue = Queue()
        self.result_queue = Queue()
        
    def distribute_tasks(self, target_list):
        """Distribute tasks across nodes"""
        for i, target in enumerate(target_list):
            node_id = i % len(self.nodes)
            self.task_queue.put({
                'node_id': node_id,
                'target': target,
                'priority': self.calculate_priority(target)
            })
    
    def calculate_priority(self, target):
        """Calculate task priority"""
        # Can be based on importance, historical success, etc.
        return random.randint(1, 10)

請求頻率控制

科學頻率設置

建議頻率規則（多次測試經驗）：

動態調整演算法：

class FrequencyController:
    def __init__(self):
        self.request_history = []
        self.error_threshold = 3
        self.success_threshold = 20
        
    def calculate_next_delay(self):
        """Calculate delay before next request"""
        recent_errors = self.count_recent_errors(300)  # errors in last 5 min
        recent_success = self.count_recent_success(300)
        
        if recent_errors > self.error_threshold:
            # Too many errors, slow down
            base_delay = 60 + (recent_errors - self.error_threshold) * 30
        elif recent_success > self.success_threshold:
            # High success, can speed up
            base_delay = max(10, 30 - (recent_success - self.success_threshold))
        else:
            # Normal
            base_delay = 30
        
        # Add jitter
        jitter = random.uniform(0.7, 1.3)
        return base_delay * jitter

時間窗口策略

滑動時間窗限流： 更精細的頻率管控：

from collections import deque
import time

class SlidingWindowRateLimit:
    def __init__(self, max_requests=100, window_size=3600):
        self.max_requests = max_requests
        self.window_size = window_size
        self.requests = deque()
    
    def can_make_request(self):
        """Check if another request can be made"""
        now = time.time()
        while self.requests and self.requests[0] < now - self.window_size:
            self.requests.popleft()
        return len(self.requests) < self.max_requests
    
    def record_request(self):
        """Log a request"""
        self.requests.append(time.time())

IP輪換與代理設置

代理伺服器類型選擇

住宅代理範例：

class ProxyManager:
    def __init__(self):
        self.proxy_pool = []
        self.current_proxy = None
        self.proxy_stats = {}
        
    def add_proxy(self, proxy_config):
        """Add proxy to pool"""
        self.proxy_pool.append(proxy_config)
        self.proxy_stats[proxy_config['id']] = {
            'success_count': 0,
            'error_count': 0,
            'last_used': 0,
            'response_time': []
        }
    
    def get_best_proxy(self):
        """Pick the best proxy"""
        available_proxies = [
            p for p in self.proxy_pool 
            if self.is_proxy_healthy(p)
        ]
        
        if not available_proxies:
            return None
            
        return max(available_proxies, key=self.calculate_proxy_score)
    
    def calculate_proxy_score(self, proxy):
        """Score proxies"""
        stats = self.proxy_stats[proxy['id']]
        total_requests = stats['success_count'] + stats['error_count']
        if total_requests == 0:
            return 0.5  # Neutral score for new proxies
        success_rate = stats['success_count'] / total_requests
        avg_response_time = sum(stats['response_time']) / len(stats['response_time'])
        score = success_rate * 0.7 + (1 / (1 + avg_response_time)) * 0.3
        return score

IP輪換策略

智能輪換演算法：

class IntelligentIPRotation:
    def __init__(self):
        self.ip_usage_history = {}
        self.cooldown_period = 1800  # 30 minutes
        
    def should_rotate_ip(self, current_ip):
        """Should we rotate IP?"""
        usage_info = self.ip_usage_history.get(current_ip, {})
        if usage_info.get('start_time', 0) + 3600 < time.time():
            return True
        if usage_info.get('request_count', 0) > 500:
            return True
        error_rate = usage_info.get('error_count', 0) / max(usage_info.get('request_count', 1), 1)
        if error_rate > 0.1:
            return True
        return False
    
    def select_next_ip(self, exclude_ips=None):
        """Select next IP"""
        exclude_ips = exclude_ips or []
        current_time = time.time()
        available_ips = []
        for ip, usage in self.ip_usage_history.items():
            if ip in exclude_ips:
                continue
            if usage.get('last_used', 0) + self.cooldown_period < current_time:
                available_ips.append(ip)
        if not available_ips:
            # Pick IP with the longest cooldown
            return min(self.ip_usage_history.keys(), 
                      key=lambda x: self.ip_usage_history[x].get('last_used', 0))
        return min(available_ips, 
                  key=lambda x: self.ip_usage_history[x].get('request_count', 0))

User-Agent偽裝技術

模擬真實瀏覽器

User-Agent 池：

class UserAgentManager:
    def __init__(self):
        self.user_agents = [
            "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36",

        ]
        self.usage_count = {ua: 0 for ua in self.user_agents}
    
    def get_random_user_agent(self):
        """Get random User-Agent, prefer least used"""
        sorted_uas = sorted(self.user_agents, key=lambda x: self.usage_count[x])
        top_candidates = sorted_uas[:3]
        selected_ua = random.choice(top_candidates)
        self.usage_count[selected_ua] += 1
        return selected_ua

常見問題與故障排除

Q1：如何判斷自己是否被Instagram偵測？

徵兆：

• HTTP 429（Too Many Requests）
• 顯示「Please wait a few minutes」或驗證碼
• 登入要求額外驗證
• 部分功能被限制

建議處理：

def detect_blocking_signals(response, content):
    blocking_indicators = [
        response.status_code == 429,
        response.status_code == 403,
        'challenge_required' in content,
        'Please wait a few minutes' in content,
        'suspicious activity' in content.lower(),
        'verify your account' in content.lower()
    ]
    return any(blocking_indicators)

Q2：代理被封快速恢復方法？

建議步驟：

1. 立即停止該代理的所有請求
2. 将該代理加入24小時黑名單
3. 從代理池挑選新代理
4. 清除該代理關聯所有session與cookie
5. 暫停5–10分鐘後再繼續

class QuickRecovery:
    def __init__(self):
        self.blocked_proxies = {}
        self.recovery_delay = 300  # 5 mins
        
    def handle_proxy_blocking(self, blocked_proxy):
        self.blocked_proxies[blocked_proxy] = time.time()
        self.cleanup_proxy_sessions(blocked_proxy)
        new_proxy = self.select_backup_proxy()
        time.sleep(self.recovery_delay)
        return new_proxy

Q3：如何提升爬取效率？

效率Tips：

1. 並發控制：

import asyncio
import aiohttp

class AsyncCrawler:
    def __init__(self, max_concurrent=5):
        self.semaphore = asyncio.Semaphore(max_concurrent)
        self.session = None
        
    async def fetch_profile(self, username):
        async with self.semaphore:
            async with self.session.get(f'/users/{username}') as response:
                return await response.json()

2. 緩存加速：

import redis
import json

class CacheManager:
    def __init__(self):
        self.redis_client = redis.Redis(host='localhost', port=6379, db=0)
        self.cache_ttl = 3600
        
    def get_cached_data(self, key):
        cached = self.redis_client.get(key)
        return json.loads(cached) if cached else None
        
    def cache_data(self, key, data):
        self.redis_client.setex(
            key, 
            self.cache_ttl, 
            json.dumps(data)
        )

Q4：如何抓取ig動態頁面（滾動載入）內容？

處理Instagram動態內容：

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

class DynamicContentHandler:
    def __init__(self, driver):
        self.driver = driver
        self.wait = WebDriverWait(driver, 10)
        
    def wait_for_followers_load(self):
        try:
            followers_container = self.wait.until(
                EC.presence_of_element_located((By.CLASS_NAME, "followers-list"))
            )
            self.scroll_to_load_more()
            return True
        except Exception as e:
            print(f"Wait for load failed: {e}")
            return False
    
    def scroll_to_load_more(self):
        last_height = self.driver.execute_script("return document.body.scrollHeight")
        while True:
            self.driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
            time.sleep(2)
            new_height = self.driver.execute_script("return document.body.scrollHeight")
            if new_height == last_height:
                break
            last_height = new_height

小結與最佳實踐

核心原則

1. 模擬真實用戶行為： 最重要的防偵側關鍵
2. 理性頻率控制： 過慢總比被封鎖好
3. 使用高品質代理： 對Instagram建議住宅代理
4. 良好監控與告警： 隨時發現並快速處理異常
5. 預備備案： 包含代理、帳號及多套策略

各層級實施建議

初階（小量）：

• 單一高品質住宅代理
• 基本頻控（30秒/請求）
• 輪替User-Agent
• 簡單失敗重試

進階（中量）：

• 代理池管理（5–10條）
• 智慧速率調整
• Session與cookie策略
• 基本監控與報警

高階（大量）：

• 分散式爬取架構
• 智能代理IP輪換
• ML 模擬人類行為
• 完整監控+自動恢復機制

風險與合規把控

1. 法律合規： 務必確認所有抓取行為符合法規
2. 技術合規： 遵守robots.txt及使用規範
3. 企業商業合規： 不傷害、不過度影響Instagram
4. 數據安全： 保護好一切用戶數據
