Crawling content that is paid, requires login, or involves personal privacy carries legal risks far higher than scraping public pages, even if it is technically feasible.
The crawler workflow can be summarized as: send an HTTP request to obtain web page content -> parse the data to extract information -> store the data -> follow links to continue crawling.
A web crawler is essentially a program that automatically retrieves web page content, simulating human web browsing behavior to scrape the needed data from the internet.
A web crawler refers to the technology of automatically accessing web pages through a program to extract and store required data.
The intelligent procurement assistant accesses supplier websites via skills or web crawlers to scrape publicly available information such as pricing pages.
The core challenge of a self-hosted search engine lies in web crawling and index building, with its crawling scope and index depth constrained by bandwidth, storage, and computing resources.
The practical section includes real projects such as scraping images and videos, automating office tasks with Excel and documents, and data storage, analysis, and mining.
There have been real cases of AI Agents autonomously operating online stores, managing social media accounts, or attempting cryptocurrency trading, most of which ended with the AI quickly making a mess of things.
Web scraping and data collection involves the terms of service of target websites and relevant laws and regulations, and compliance must be confirmed when taking on orders
