Research on Python Crawler Search System Based on Computer Big Data
Yuhan Wang · 2023
This paper uses Python crawler technology, designed a commodity collection and analysis method. The system uses Python operation automation testing framework to simulate manual web browsing to bypass the complex anti-crawler encryption algorithm edited by complex JavaScript in some dynamic web pages and obtain the specified page information. This article uses the Requests library to download the resulting item information from searches by keyword. Both regular expressions and Beautiful Soup were used for initial cleaning of the data. Finally, the system stores the data into MongoDB database. Practice shows that Python language has very high feasibility and effectiveness, which not only ensures the implementation effect of web crawler framework, but also improves the performance of web crawler system. The system brings good user experience.
