Embodiment Construction

[0025] As mentioned in the background technology, with the development and popularization of anti-crawler technology, there are problems in crawling data by crawlers: 1. The maintenance cost of crawlers increases; technology; 3. Data omission, which affects the integrity of the data.

[0026] The technical scheme of the present invention can determine the anti-crawler configuration set by the target visited website through the status code or page data fed back by the target visited website, so that the cracking operation for the anti-crawler configuration can be determined according to the status code or page data, thereby updating the access request Revisit the target website to obtain the website content of the target website, improve the crawler's automatic response capability, and improve the efficiency of web crawlers in crawling data.

[0027] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of...

Abstract

The invention discloses a data crawling method and device, a storage medium and a terminal. The data crawling method comprises the steps of simulating a browser to send an access request for a targetaccess website; receiving a response message of the target access website for the access request, wherein the response message comprises a state code and page data; updating the access request according to the state code or the page data; and obtaining the content in the target access website by utilizing the updated access request. According to the technical scheme, the data crawling efficiency of the web crawler can be improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and device for crawling data, a storage medium, and a terminal. Background technique [0002] A web crawler is a program or script that automatically and efficiently grabs Internet information according to certain rules. [0003] With the rapid development of big data, more and more enterprises and websites want to prevent website data from being collected in batches at high speed by web crawlers, and anti-crawler technology has emerged as the times require. Anti-crawler technologies are also different, for example, restricting the access frequency of Internet Protocol Address (IP), restricting the speed of browsing web pages, account login verification, input verification code and other technologies. [0004] However, with the development and popularization of anti-crawler technology, there are problems with crawler crawling data: 1. The cost of crawler...
