Research and implementation of multi-threaded Web crawler system based on Python
A Web crawler is a method of obtaining target data by programming to simulate a browser accessing a server.In the big data environment,the speed of Web crawler is one of the important evaluation criteria affecting the performance of Web crawler.The Python language is widely used in scenarios such as Web crawler and data analysis due to its rich third-party libraries.Based on the Python programming language,the solution to improve the speed of Web crawling is explored in this paper with the target of improving the speed of Web crawling.And taking the intelligent image crawling on a certain Website as an example,a multi-threaded crawling system is implemented.
