Integrasi dengan Python Scrapy

Pelajari cara mengonfigurasi crawler Python Scrapy untuk mengarahkan permintaan melalui port XProxy serta mengimplementasikan middleware kustom guna menangani rotasi IP otomatis pada ambang batas permintaan tertentu.

Mengapa menggunakan Scrapy dengan XProxy?

Scrapy adalah framework scraping Python asinkron yang dirancang untuk crawling data berperforma tinggi. Saat menjalankan scraper dengan throughput tinggi, penggunaan cloud proxy berbasis meteran menimbulkan biaya bulanan yang sangat besar. Menjalankan Scrapy melalui farm XProxy milik Anda sendiri dengan kartu SIM lokal menyediakan pipeline data tanpa batas, menghemat ribuan dolar sekaligus memanfaatkan IP CGNAT dinamis dari operator seluler.

Konfigurasi proxy dasar di Scrapy

Cara paling sederhana untuk menggunakan XProxy di Scrapy adalah dengan mengonfigurasi HttpProxyMiddleware standar dan menambahkan pengaturan proxy langsung ke settings.py atau menentukannya per permintaan.

Opsi A: Konfigurasi global di settings.py

Buka settings.py pada proyek Scrapy Anda dan tambahkan pengaturan berikut:

settings.py

# Enable the default HTTP Proxy Middleware
DOWNLOADER_MIDDLEWARES = {
    'scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware': 400,
}

# Define your XProxy SOCKS5 or HTTP proxy URL
# Replace 192.168.6.7:5001 with your XProxy server IP and port
HTTP_PROXY = 'http://your_username:[email protected]:5001'

# Set proxy to environment variable (or configure in custom middleware)

Opsi B: Meneruskan proxy secara dinamis per Request

Anda juga dapat menetapkan koneksi proxy secara langsung di dalam file spider Anda untuk setiap permintaan:

myspider.py

import scrapy

class MySpider(scrapy.Spider):
    name = 'myspider'

    def start_requests(self):
        urls = ['https://httpbin.org/ip']
        for url in urls:
            yield scrapy.Request(
                url=url,
                callback=self.parse,
                meta={
                    # Route this specific request through XProxy port 5001
                    'proxy': 'http://your_username:[email protected]:5001'
                }
            )

    def parse(self, response):
        self.logger.info(f"Response: {response.text}")

Lanjutan: Middleware rotasi IP otomatis

Untuk merotasi IP seluler XProxy Anda secara otomatis saat Google menampilkan CAPTCHA, atau setelah sejumlah permintaan halaman tertentu, implementasikan middleware Scrapy kustom:

middlewares.py

import time
import requests
from scrapy.exceptions import NotConfigured

class XProxyRotationMiddleware:
    def __init__(self, rotate_url, request_limit=100):
        self.rotate_url = rotate_url
        self.request_limit = request_limit
        self.request_count = 0

    @classmethod
    def from_crawler(cls, crawler):
        # Read settings from settings.py
        rotate_url = crawler.settings.get('XPROXY_ROTATE_URL')
        request_limit = crawler.settings.getint('XPROXY_REQUEST_LIMIT', 100)
        
        if not rotate_url:
            raise NotConfigured
            
        return cls(rotate_url, request_limit)

    def process_request(self, request, spider):
        self.request_count += 1
        
        # Trigger rotation if limit reached
        if self.request_count >= self.request_limit:
            spider.logger.info("Request limit reached. Triggering XProxy IP rotation...")
            self._trigger_rotation(spider)
            self.request_count = 0
            
    def _trigger_rotation(self, spider):
        try:
            response = requests.get(self.rotate_url)
            spider.logger.info(f"IP rotation triggered: {response.status_code} - {response.text}")
            # Wait for 6 seconds for cellular reconnection
            time.sleep(6)
        except Exception as e:
            spider.logger.error(f"Failed to trigger rotation: {str(e)}")

Aktifkan middleware di settings.py Anda:

settings.py

DOWNLOADER_MIDDLEWARES = {
    'myproject.middlewares.XProxyRotationMiddleware': 350,
    'scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware': 400,
}

# The XProxy Rotation API URL for your device position
XPROXY_ROTATE_URL = 'http://192.168.6.7:8081/api/v1/rotate_ip/position/1'
# Rotate the IP address after every 150 requests
XPROXY_REQUEST_LIMIT = 150

Why High-Quality SOCKS5 UDP & Mobile Proxies Matter for Python Scrapy Crawlers

Using cheap datacenter proxies or basic HTTP proxies in antidetect profiles leads to instant account suspensions on Facebook, Google, TikTok, and Amazon. Here is why XProxy's self-hosted 4G/5G mobile proxies deliver superior anonymity and trust:

SOCKS5 with Full UDP Support: Unlike standard HTTP proxies that drop UDP packets, XProxy SOCKS5 proxies fully support UDP datagrams. This ensures WebRTC, DNS queries, and real-time audio/video sockets route securely through your proxy without revealing your real IP address.
Instant REST API IP Rotation: Trigger cellular IP rotation on demand via simple HTTP GET requests (e.g. http://192.168.6.7:8081/api/v1/rotate_ip/position/1). Reconnect 4G/5G USB modems in 3 to 8 seconds with zero proxy dropouts.
100% WebRTC & DNS Leak Protection: Combined with XProxy's local LAN gateway and TCP OS Spoofing, your browser profiles maintain pristine anonymity scores on BrowserLeaks, Whoer, Pixelscan, and IPhey.
Carrier-Grade NAT (CGNAT) Trust: Mobile carrier IPs are shared by thousands of active smartphone users. Major platforms never ban mobile IP ranges, granting your accounts maximum trust.
