Deep Crawling
Deep Crawling refers to a technical method in which a web crawler not only collects information from the homepage or surface pages of a target website but also recursively follows links within pages to continuously access and collect data from deeper levels of the site. Unlike shallow crawling, which only captures surface-level pages, deep crawling can penetrate a website's directory structure, pagination navigation, category links, and dynamically loaded content, thereby obtaining more comprehensive and complete data resources. This technique typically requires the integration of link deduplication, crawling strategy optimization, anti-scraping mechanism handling, and distributed scheduling to efficiently and stably complete large-scale data collection tasks.

Web API Fetching
Web API Fetching is mainly implemented using the Fetch API, which is a modern HTTP client interface based on Promise, used for asynchronous resource retrieval in browsers and Node.js (version 18+) environments. It sends requests through the fetch() method, supports cross origin resource sharing (CORS), and returns a Promise object parsed as a response result. It is suitable for scenarios that require dynamic data loading, backend interaction, or A/B testing.
