Problems solved by technology

[0002] A web crawler is a program or script that crawls network information according to predetermined rules. However, with the continuous advancement of anti-crawler technology, data crawling failures often occur when using a predetermined crawler system for web data crawling.
[0003] At present, to deal with crawling failures, we mainly analyze the reasons for crawling failures and use various anti-crawler technologies for continuous or cyclic access, resulting in a great waste of resources and an increase in data capture costs

Embodiment Construction

[0028] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0029] The network data acquisition method provided by this application can be applied to a terminal or a server alone, or partially applied to a terminal or a server. Taking the communication between a terminal and a server as an example, such as figure 1 shown in the application environment. Wherein, the terminal 102 communicates with the server 104 through the network. The user accesses the server 104 through the terminal 102 to acquire a web page, thereby realizing acquisition of web data. Wherein, the terminal 102 can be, but not limited to, various personal compute...

Abstract

The invention relates to a network data acquisition method and device, computer equipment and a storage medium. The method comprises the steps of monitoring a data capture state under a current downloading strategy in a crawling system, wherein the data capture state comprises page downloading failure, page analysis failure and / or page analysis success; determining a failure index corresponding toa current downloading strategy according to the data capture state; and if the failure index is greater than or equal to a first preset threshold, switching the current downloading strategy into a target downloading strategy, wherein the target downloading strategy is one of a plurality of downloading strategies preset in the crawling system. By adopting the method, invalid grabbing and great waste of data crawling resources can be avoided.

Description

technical field [0001] The present application relates to the technical field of web crawlers, in particular to a network data acquisition method, device, computer equipment and storage medium. Background technique [0002] A web crawler is a program or script that crawls network information according to predetermined rules. However, with the continuous advancement of anti-crawler technology, data crawling failures often occur when using established crawler systems for web data crawling. [0003] At present, to deal with crawling failures, we mainly analyze the reasons for crawling failures and use various anti-crawler technologies for continuous or cyclic access, resulting in a great waste of resources and an increase in data capture costs. Contents of the invention [0004] Based on this, it is necessary to provide a network data acquisition method, device, computer equipment and storage medium for the above technical problems. [0005] A network data acquisition method...
