How to Create a Proxy-Powered RSS Aggregator

Choosing the Right Loom: Why a Proxy-Powered RSS Aggregator?

In the bazaars of the digital world, much like the bustling markets of Kabul, information is plentiful but access is not always straightforward. Many RSS feeds restrict access, rate-limit requests, or block scrapers by IP. Just as a skilled weaver selects the finest threads to avoid knots and tears, a proxy-powered aggregator selects diverse proxies to ensure seamless, reliable data collection.

The Anatomy of an RSS Aggregator

At its core, an RSS aggregator harvests content from multiple feeds, parses the data, and presents a unified stream. To weave in proxies, you must thread them through your request mechanism, ensuring each fetch is both anonymous and distributed.

Components and Their Roles

Sourcing Proxies: The ProxyRoller Tapestry

No thread is more vital than the proxy list. ProxyRoller offers a loom full of free, rotating HTTP and SOCKS proxies, refreshed regularly. Their API and bulk export tools provide a ready supply—just as a master weaver trusts only the finest suppliers.

Example: Fetching Proxies from ProxyRoller

import requests

response = requests.get("https://proxyroller.com/api/proxies?type=http")
proxies = response.json()  # List of proxy strings like 'ip:port'

Weaving the Fetcher: Proxy-Enabled Requests

The fetcher must gracefully alternate proxies, just as a carpet’s pattern alternates colors. Use a robust HTTP library, like requests in Python, and pair each request with a new proxy.

import random

def fetch_feed(feed_url, proxies):
    proxy = random.choice(proxies)
    proxy_dict = {
        "http": f"http://{proxy}",
        "https": f"http://{proxy}"
    }
    try:
        resp = requests.get(feed_url, proxies=proxy_dict, timeout=10)
        resp.raise_for_status()
        return resp.content
    except Exception as e:
        print(f"Failed with proxy {proxy}: {e}")
        return None

Parsing the Pattern: Extracting RSS Items

Once the threads (feeds) are fetched, use a parser like feedparser to extract stories.

import feedparser

def parse_feed(xml_content):
    return feedparser.parse(xml_content)['entries']

Handling Knots: Error Management and Proxy Rotation

As with every weaving, knots and tangles are inevitable. When a proxy fails, it must be discarded or retried sparingly. Implement retry logic and periodic updates from ProxyRoller.

from time import sleep

def robust_fetch(feed_url, proxies, max_retries=5):
    for _ in range(max_retries):
        content = fetch_feed(feed_url, proxies)
        if content:
            return content
        sleep(2)  # Pause between attempts, like a craftsman regrouping
    return None

Storing the Silk: Aggregating and Serving Data

A database, such as SQLite, MongoDB, or PostgreSQL, serves as your storehouse. Each new article is logged with its source, timestamp, and content.

Schema Example:

Security, Ethics, and Respect: The Weaver’s Oath

Just as Afghan tradition demands respect for the marketplace, so must scrapers honor target sites’ robots.txt and rate limits. Proxies are tools, not weapons—use them responsibly.

Complete Script Example

import requests, random, feedparser, sqlite3, time

# Fetch proxies from ProxyRoller
proxies = requests.get("https://proxyroller.com/api/proxies?type=http").json()

# Simple SQLite setup
conn = sqlite3.connect('rss.db')
c = conn.cursor()
c.execute('''CREATE TABLE IF NOT EXISTS articles
             (id TEXT PRIMARY KEY, feed_url TEXT, title TEXT, link TEXT, published TEXT, summary TEXT)''')

feed_urls = ['https://rss.nytimes.com/services/xml/rss/nyt/World.xml']

for feed_url in feed_urls:
    for attempt in range(5):
        proxy = random.choice(proxies)
        try:
            resp = requests.get(feed_url, proxies={"http": f"http://{proxy}", "https": f"http://{proxy}"}, timeout=10)
            if resp.status_code == 200:
                entries = feedparser.parse(resp.content)['entries']
                for entry in entries:
                    c.execute('INSERT OR IGNORE INTO articles VALUES (?, ?, ?, ?, ?, ?)',
                              (entry.get('id', entry['link']), feed_url, entry['title'], entry['link'],
                               entry.get('published', ''), entry.get('summary', '')))
                conn.commit()
                break
        except Exception as e:
            print(f"Error with proxy {proxy}: {e}")
        time.sleep(2)

conn.close()
