Design of Data Capture Program Based on Web Crawler Technology

Abstract

With the advent of the Internet of things era and the vigorous development of electronic information era, the network information resources are growing exponentially. Faced with the demand of obtaining useful information, based on the general web crawler technology, this paper uses Python software to design a deep and optimized web crawler data fetching program. This crawler program can effectively solve a series of problems, such as waiting time, information overlapping and information incompleteness, so that the crawler has good performance.
