To set up a proxy on Scrapy

Proxy as a request parameter

The request parameters technique, as the name implies, requires supplying proxy credentials as a separate parameter to the Scrapy request method. The meta argument can be used to pass the ProxyUrl and user credentials to the Request method.

The generic format of a proxy endpoint is as follows:

Protocol://username:password@ProxyUrl:Port

Depending on the sort of proxy you’ve purchased, the Protocol, user credentials, ProxyUrl, and port number will differ. if you don’t have a proxy yet we recommend you Proxy-cheap.

Creating custom Scrapy proxy middleware

When you have many spiders, using Scrapy proxy middleware comes in helpful. It enables the spiders to easily add, remove, and modify proxy endpoints without requiring any changes to the spiders’ real code.

To utilize a proxy middleware in Scrapy, add it to the middleware list in your “settings.py” file. Let us first create a middleware before registering it.

Open the “middlewares.py” file and add the custom proxy middleware code below:

class BookProxyMiddleware(object):
   @classmethod
   def from_crawler(cls, crawler):
       return cls(crawler.settings)
 
   def __init__(self, settings):
       self.username = settings.get('PROXY_USER')
       self.password = settings.get('PROXY_PASSWORD')
       self.url = settings.get('PROXY_URL')
       self.port = settings.get('PROXY_PORT')
 
   def process_request(self, request, spider):
       host = f'http://{self.username}:{self.password}@{self.url}:{self.port}'
       request.meta['proxy'] = host

BookProxyMiddleware anticipates all required information for a proxy endpoint and adds it to the request’s meta parameter.

The next step is to add this middleware to “settings.py” so it may act as an intermediary for each crawl/scrape request. Open the “settings.py” file and make the following changes:

PROXY_USER = 'Your username'
PROXY_PASSWORD = 'Your password'
PROXY_URL = 'Your PROXY_URL'
PROXY_PORT = 'Your PROXY_PORT'

DOWNLOADER_MIDDLEWARES = {
    'scrapyproject.middlewares.BookProxyMiddleware': 100,
    'scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware': 110,
}

The BookProxyMiddleware is added to the list of DOWNLOADER_MIDDLEWARES in “settings.py” with a sequence number of 100. The middleware is applied to the spiders in the sequence numbers’ ascending order.

How to Test Scrapy Proxies

If you followed any of the preceding methods and entered the necessary proxy data, your proxies will be established from the Scrapy end. But do they work? You must put them to the test.

Send a request to any of the proxy search tools, such as “ShowMyIP“, and if it returns your real IP address, something is amiss with your setup or the proxies you’re attempting to utilize.

Conclusion

Finally, the ability to set up proxies in Scrapy allows for endless data potential while adhering to ethical bounds. With this newfound information, you can embark on your web scraping journey with confidence, ready to face the challenge and properly acquire useful insights. By successfully deploying proxies, you can assure a seamless and uninterrupted scraping experience while also protecting the integrity of the things and sites you visit.

Happy scraping!
