This guide provides a step-by-step tutorial on installation and deployment, alongside recommendations for using rotating residential proxies in batch scraping scenarios (sticky sessions for logged-in tasks, and per-request rotation for high-concurrency scraping). Using IPFoxy as an example, it details the entire execution workflow from BrowserConfig (browser environment setup) and CrawlerRunConfig (ProxyConfig proxy settings) to script execution, while offering practical troubleshooting strategies for common issues such as 403\/429 errors, missing content extraction, and proxy connection failures."}
