What are some examples of Scrapy middleware?

Can you give me some examples of Scrapy middleware?

Sure! Scrapy middleware is a way to process requests and responses globally. Examples include User-Agent middleware, which allows you to set a custom User-Agent for your requests, and Retry middleware, which automatically retries failed requests.

How do I implement a custom middleware in Scrapy?

To implement custom middleware, you need to create a new Python class and define methods like process_request and process_response. Then, add your middleware class to the DOWNLOADER_MIDDLEWARES setting in your Scrapy project.

What is the purpose of the Retry middleware?

The Retry middleware is used to handle failed requests by automatically retrying them a specified number of times, which helps improve the robustness of your scraping.

Can I use multiple middlewares at the same time?

Yes, you can use multiple middlewares in Scrapy. They will be executed in the order you specify in the DOWNLOADER_MIDDLEWARES setting.
