Data filtering method, device, server and readable storage medium

Abstract

The embodiment of the invention provides a data filtering method and device, a server and a readable storage medium. The method comprises the steps that when an HTTP request is received, an HTTP protocol header and HTTP form data are obtained from the HTTP request, and the HTTP form data comprises form data of multiple data types; analysis is conducted on the HTTP protocol header to obtain data separators of the HTTP protocol header; form data of the corresponding data types is obtained by sorting the HTTP form data according to the analyzed data separators, and based on a preset data filtering rule, filtering is conducted on the form data of the corresponding data types of the HTTP form data. According to the method, classified filtering of the HTTP form data can be performed to improve accuracy of data safe filtering and prevent mistaken interception of image data or file data.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a data filtering method, device, server and readable storage medium. Background technique [0002] In the field of Web development, it is often necessary to perform security filtering on HTTP form data, such as XSS filtering, SQL injection filtering, etc. These operations can effectively protect the security of the product. At present, a commonly used method of security filtering is to divide the data of the HTTP request with fixed length and perform regular matching. If an illegal character is matched, the HTTP request is intercepted. However, since the form data may contain data types such as file data, image data, and text data, and the above method cannot classify and filter the HTTP form data, it may cause the problem that the image data or file data that needs to be viewed is intercepted by mistake. Summary of the invention [0003] In order to overcome the above-menti...
