Scrapy provides various anti-scraping mechanisms to deal with website anti-scraping strategies. First, Scrapy supports setting User-Agent to simulate different browser accesses. Second, Scrapy supports cookie handling to maintain session state. Scrapy also supports proxy settings, allowing IP address rotation through proxy pools to avoid being blocked. Scrapy's automatic throttling feature can automatically adjust request speed based on the website's response time, avoiding putting too much pressure on the server. Scrapy also supports setting download delays, adding random delays between requests. For websites that require login, Scrapy can send login requests through FormRequest and handle the response after login. Scrapy also supports handling CAPTCHAs, although it needs to be combined with third-party CAPTCHA recognition services. In addition, Scrapy can add custom anti-scraping strategies through middleware, such as randomizing request headers, handling redirects, and processing exceptions. Developers can also use Scrapy's caching feature to reduce the number of requests to target websites.
