How to Set Up Proxies with Scrapy (Configuration Tutorial)

10 Views

Scrapy is a web crawling framework developed in the Python language. It uses Twisted for asynchronous network request processing, allowing the transformation of unstructured or semi-structured data into structured data.

Scrapy can be used in a variety of programs, including data mining, information processing, and storing historical data. It was originally designed for web scraping (more precisely, network scraping) but can also be used to retrieve data returned by APIs (such as Amazon Associates Web Services) or for general web crawling.

Proxies act as an intermediary server that routes your web traffic. Using proxies with Scrapy helps hide your real IP address. This prevents sites from blocking you from making too many requests from a single IP. Proxies also provide location spoofing – you can appear to be accessing a site from another country.

Whether you're scraping on Windows, macOS, or Linux, proxies are essential for avoiding blocks and captchas. Now let's see how to set up Scrapy and integrate proxies on the three major operating systems. But first, let's find,

Some popular proxy providers include:

BrightData – Rotating residential proxies ideal for scraping. Offers US and international locations.
Smartproxy – Residential proxies with over 55 million IPs worldwide.
Proxy-Seller – Premium datacenter proxies are great for general web scraping.
Soax – Reliable and affordable residential rotating proxies.

Configuring Proxies with Scrapyon Windows, macOS, and Linux

In this section, I'll provide step-by-step instructions for setting up and integrating proxies in Scrapy on Windows, macOS and Linux.

Windows Setup

Here is how to get started with proxies on Windows:

1. Install Python and pip

Download latest Python from python.org
Make sure to check “Add Python to PATH” during installation
Open Command Prompt and run pip --version to confirm pip installed

2. Install virtualenv (optional but recommended)

pip install virtualenv

3. Create a virtual environment for Scrapy:

virtualenv myenv
myenv\Scripts\activate

4. Install Scrapy inside virtual environment:

pip install Scrapy

5. Generate a new Scrapy project:

scrapy startproject myproject

6. Create a spider:

cd myproject
scrapy genspider example example.com

7. Export proxies from provider's dashboard

Save proxy IPs in proxies.txt file:

username:[email protected]:8080
username:[email protected]:8080

8. Add proxies to settings.py:

# settings.py

ROTATING_PROXY_LIST_PATH = r'C:\path\to\proxies.txt' 

DOWNLOADER_MIDDLEWARES = {
    # ...
    'rotating_proxies.middlewares.RotatingProxyMiddleware': 610,
    'rotating_proxies.middlewares.BanDetectionMiddleware': 620,
}

9. Run spider:

This covers the key steps to get started with proxies on a Windows machine. Next let's see how to setup proxies on macOS.

macOS Setup

Here is the process for setting up proxies with Scrapy on macOS:

1. Install Python and pip

Install Python from python.org
Open Terminal and run pip --version to confirm pip installed

2. Create a virtual environment:

python3 -m venv myenv
source myenv/bin/activate

3. Install Scrapy in virtual environment:

pip install Scrapy

4. Generate a Scrapy project:

scrapy startproject myproject

5. Create a spider:

cd myproject
scrapy genspider example example.com

6. Export proxies and save to proxies.txt:

username:[email protected]:8080  
username:[email protected]:8080

7. Enable proxies in settings.py:

# settings.py

ROTATING_PROXY_LIST_PATH = '/Users/myuser/proxies.txt'

DOWNLOADER_MIDDLEWARES = {
    # ... 
    'rotating_proxies.middlewares.RotatingProxyMiddleware': 610,
    'rotating_proxies.middlewares.BanDetectionMiddleware': 620,
}

8. Run spider:

ext let's walk through setting up proxies on Linux.

Linux Setup

Here are the steps to configure proxies with Scrapy on Linux:

1. Install Python and pip

Most Linux distros come with Python pre-installed. Confirm with:

python --version
pip --version

If missing, install them through your distro's package manager.

2. Create a virtual environment:

python3 -m venv myenv
source myenv/bin/activate

3. Install Scrapy:

pip install Scrapy

4. Generate a Scrapy project:

scrapy startproject myproject

5. Create a spider:

cd myproject 
scrapy genspider example example.com

6. Export proxy list and save to /home/user/proxies.txt

7. Configure proxies in settings.py:

# settings.py

ROTATING_PROXY_LIST_PATH = '/home/user/proxies.txt'  

DOWNLOADER_MIDDLEWARES = {
  # ...
  'rotating_proxies.middlewares.RotatingProxyMiddleware': 610,
  'rotating_proxies.middlewares.BanDetectionMiddleware': 620, 
}

8. Run spider:

scrapy crawl example

Troubleshooting Proxy Issues

Here are some common issues and solutions when using proxies:

Proxy connection errors

Verify username/password are correct
Check proxy allows HTTP/HTTPS traffic
Try a different proxy server

Captchas and blocks occurring

Use more proxies and implement rotation
Add delays between requests
Use proxies matching target site's location

Spider stuck on certain domains

Adjust CONCURRENT_REQUESTS setting
Increase DOWNLOAD_TIMEOUT
Use proxy pool with failover

Difficulties configuring backconnects

Consult provider's docs for specific backconnect endpoints
Enable Keep-Alive header and disable connection re-use

Also monitor your proxies performance and bans. Quickly replace non-working IPs for optimal uptime.

Conclusion

And that covers everything you need to start scraping with proxies using Scrapy on any platform!

The key takeaways are:

Proxies are crucial for stable large-scale scraping
Easily integrate proxies via middleware or request parameters
Implement proxy rotation to distribute requests
Residential proxies like BrightData provide JS rendering and avoid blocks
Monitor performance and replace banned IPs for best results

I hope this comprehensive tutorial gives you all the knowledge to start scraping with proxies on any platform using Scrapy! Proxies are crucial for stable web scraping and avoiding IP blocks.
