Abstract

The invention discloses an acquisition method of a web crawler request and an acquisition device thereof. The acquisition method comprises the steps: acquiring verification code images of to-be-crawled resource information; performing division and noise reduction to the verification code images to obtain multiple first images; performing binarization to all first images to obtain the first matrixes of all first images; reading the second matrixes corresponding to the first matrixes from a database; acquiring characters indicated by the second matrixes to obtain verification code information; generating the web crawler request by the verification code information and the user information in advance acquired, wherein the web crawler request is used to acquire the resource information. Thus, through the method and the device, the low web crawling efficiency caused by manual intervention is partly solved in the existing technology, and the web crawling efficiency effect is improved.

Description

Technical field [0001] The present invention relates to the Internet field, and in particular, to a method and device for obtaining a web crawler request. Background technique [0002] With the rapid development of the Internet, network resources have become more and more abundant, and the artificial search for such information is far from satisfying the demand. How to effectively extract and use this information has become a huge challenge. In order to solve the effective and intelligent extraction of information, web crawlers came into being. Before a web crawler obtains a specific resource, it first constructs the corresponding request header information, and sends a request to a specific site in the form of Post or Get cookie settings, and then obtains the response resource information. However, resource information of some sites on the Internet can only be obtained after logging in, and even some sites require verification code information to be entered when logging in for ...
