Rose Lyn Villamor
Scrapy is a powerful tool that can help you automate the process of getting information from the Internet. But even with all of its power, there are times when you might need to send your requests through a middleman, like a proxy server.
If you don’t know how to set up a proxy for Scrapy, don’t worry! This guide will explain why it’s necessary, what types of proxies work with Scrapy, and how to add them to your configuration file so your scraper can use them.
What is Scrapy?
Web scraping is the process of getting information from websites. Scrapy is a tool that automates this process. You can get information from any site with an HTML-based interface that is open to the public, which is most sites these days.
Scrapy sends out requests and reads the HTML responses to get the data you want. It’s like an automated browser programmed to go through your website, “scrape” certain parts and get the information it needs.
You can use Scrapy for many different things, like analyzing your competitors’ websites, making contact lists for marketing campaigns, checking social media sites for news and trends, and so on. When you have information from all over the Internet at your fingertips, you can do anything.
Why do you need a proxy for Scrapy?
You’ll need a proxy if you use web scrapers. It is legal to scrape websites, but most websites do not let you do this. Web scrapers tend to make the server load go up, which can cause the servers to go down or even crash. Because of this, most web admins use technologies that actively look for and stop web scraping.
Web scrapers are easy to find because they send the server many requests every second. Humans can’t make this many requests, so the server can tell when a scraper is around. But you can get around this problem if you use a proxy. It gives you different IP addresses so that you can make more than one request.
Another reason to use a proxy in web scraping is geo-location. This is especially useful if you want to scrape data from a website that’s not available in your country or if you want to scrape data from a website that is only available in one language.
A proxy will help you get to the site by giving you an IP address from somewhere else. Then, Scrapy can take this IP address and use it to get information for scraping.
What Types Of Proxies Work With Scrapy?
Scrapy is a free service, but unlike some of its competitors, it does not come with a proxy. You must set it up yourself.
There are two types of proxies you can use with Scrapy: data center and residential proxies. However, if you want seamless web scraping, you should use premium residential proxies. These are IP addresses generated by internet service providers. Meaning they came from real devices, which is why they make your scrapers almost impossible to be detected.
Moreover, some residential proxy providers use a rotating algorithm that is done automatically. This means that the provider automatically changes the proxies, so you don’t have to make any other changes to the scraper. With this, you can keep your connection even if your IP address changes every now and then. It will look like the requests are coming from many different places.
When choosing a proxy for Scrapy, it’s important to avoid using free proxies because they don’t usually work well with Scrapy. They might also be slow or have other problems that make it hard for you to scrape data well.
How to add proxies to Scrapy?
When you’re using Scrapy, there are two ways to set proxies:
1. Parameter
Passing the proxy as a parameter is the easiest way to set proxies in Scrapy. If you want to use a certain proxy, this is the best way to do it. Scrapy has software called HttpProxyMiddleware that gets the proxy value from the request and sets it up correctly.
2. Middleware
To make things more modular, you have to make your middleware. Middleware is a piece of code that Scrapy uses to handle requests. You can find more information about it here.
How to check if a proxy is working in Scrapy?
After adding the proxy to Scrapy, you should run a trial to see if it works. To do this, send a request to websites that display your IP address, such as whatismyipaddress.com and whatismyip.com. If you get your home IP address, something must be fixed, and you must double-check your scraper. Otherwise, you are good to go.
Conclusion
Scrapy is a powerful framework for web scraping that can get information from websites. A proxy is a tool that lets you hide your IP address and location, which is important if you want to scrape data from websites.
