Integrating Oxylabs' Residential Proxies with AIOHTTP

Requirements for the Integration

For the integration to work you'll need to install aiohttp library, use Python 3.6 version or higher and Residential Proxies.
If you don't have aiohttp library, you can install it by using pip command:

pip install aiohttp

You can get Residential Proxies here: https://oxy.yt/arWH

Proxy Authentication

There are 2 ways to authenticate proxies with aiohttp.
The first way is to authorize and pass credentials along with the proxy URL using aiohttp.BasicAuth:

import aiohttp

USER = "user"
PASSWORD = "pass"
END_POINT = "pr.oxylabs.io:7777"
 
async def fetch():
    async with aiohttp.ClientSession() as session:
        proxy_auth = aiohttp.BasicAuth(USER, PASSWORD)
        async with session.get(
                "https://ip.oxylabs.io/location", 
                proxy="http://pr.oxylabs.io:7777", 
                proxy_auth=proxy_auth ,
        ) as resp:
            print(await resp.text())

The second one is by passing authentication credentials in proxy URL:

import aiohttp

USER = "user"
PASSWORD = "pass"
END_POINT = "pr.oxylabs.io:7777"

async def fetch():
    async with aiohttp.ClientSession() as session:
        async with session.get(
                "https://ip.oxylabs.io/location", 
                proxy=f"http://{USER}:{PASSWORD}@{END_POINT}",
        ) as resp: 
            print(await resp.text())

In order to use your own proxies, adjust user and pass fields with your Oxylabs account credentials.

Testing Proxies

To see if the proxy is working, try visiting https://ip.oxylabs.io/location. If everything is working correctly, it will return an IP address of a proxy that you're currently using.

Sample Project: Extracting Data From Multiple Pages

To better understand how residential proxies can be utilized for asynchronous data extracting operations, we wrote a sample project to scrape product listing data and save the output to a CSV file. The proxy rotation allows us to send multiple requests at once risk-free – meaning that we don't need to worry about CAPTCHA or getting blocked. This makes the web scraping process extremely fast and efficient – now you can extract data from thousands of products in a matter of seconds!

import asyncio
import time

import aiohttp
import pandas as pd
from bs4 import BeautifulSoup

USER = "user"
PASSWORD = "pass"
END_POINT = "pr.oxylabs.io:7777"

# Generate a list of URLs to scrape.
url_list = [
    f"https://books.toscrape.com/catalogue/category/books_1/page-{page_num}.html"
    for page_num in range(1, 51)
]


async def parse_data(text, results_list):
    soup = BeautifulSoup(text, "lxml")
    for product_data in soup.select("ol.row > li > article.product_pod"):
        data = {
            "title": product_data.select_one("h3 > a")["title"],
            "url": product_data.select_one("h3 > a").get("href")[5:],
            "product_price": product_data.select_one("p.price_color").text,
            "stars": product_data.select_one("p")["class"][1],
        }
        results_list.append(data)  # Fill results_list by reference.
        print(f"Extracted data for a book: {data['title']}")


async def fetch(session, sem, url, results_list):
    async with sem:
        async with session.get(
            url,

        ) as response:
            await parse_data(await response.text(), results_list)


async def create_jobs(results_list):
    sem = asyncio.Semaphore(4)
    async with aiohttp.ClientSession() as session:
        await asyncio.gather(
            *[fetch(session, sem, url, results_list) for url in url_list]
        )


if __name__ == "__main__":
    results = []
    start = time.perf_counter()

    # Different EventLoopPolicy must be loaded if you're using Windows OS.
    # This helps to avoid "Event Loop is closed" error.
    if sys.platform.startswith("win") and sys.version_info.minor >= 8:
        asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())

    try:
        asyncio.run(create_jobs(results))
    except Exception as e:
        print(e)
        print("We broke, but there might still be some results")

    print(
        f"\nTotal of {len(results)} products from {len(url_list)} pages "
        f"gathered in {time.perf_counter() - start:.2f} seconds.",
    )
    df = pd.DataFrame(results)
    df["url"] = df["url"].map(
        lambda x: "".join(["https://books.toscrape.com/catalogue", x])
    )
    filename = "scraped-books.csv"
    df.to_csv(filename, encoding="utf-8-sig", index=False)
    print(f"\nExtracted data can be found at {os.path.join(os.getcwd(), filename)}")

If you want to test the project's script by yourself, you'll need to install some additional packages. To do that, simply download requirements.txt file and use pip command:

pip install -r requirements.txt
