Problems solved by technology

[0004] However, the code similarity detection tools used in related technologies can only determine the similarity between programs by comparing two codes. When applied to small program code detection, due to the large number of small programs, the detection of small program code similarity The efficiency is low, which affects the online speed of the applet

Abstract

The invention discloses an applet code similarity determination method and device, a server and a storage medium, and relates to the field of computers. The method comprises the steps of obtaining anabstract syntax tree of a small program code corresponding to a first small program; performing feature extraction on the abstract syntax tree based on a parent-child relationship between nodes in theabstract syntax tree to obtain code features of the first applet; generating a first applet fingerprint of the first applet according to the code features; and according to the first applet fingerprint and a second applet fingerprint of a second applet in an applet fingerprint library, determining code similarity between the first applet and the second applet. By adopting the method provided by the embodiment of the invention, the applet fingerprint is generated for the existing applet in advance based on the abstract syntax tree, then similarity detection can be carried out by utilizing theapplet fingerprint stored in the applet fingerprint library, source codes of every two applets do not need to be analyzed and compared, and the applet code similarity detection efficiency is improved.

Description

technical field [0001] The present application relates to the field of computers, in particular to a method, device, server and storage medium for determining similarity of applet codes. Background technique [0002] An applet is a program that depends on a host program to run. Users only need to install the host program, and can add and use various small programs in the host program at any time. [0003] The developer of the host program provides an open platform, and the developer of the mini program can upload the mini program through the open platform. The developer of the host program will review the content of the mini program, and after passing the review, the mini program will be launched. In addition, in order to ensure the homogeneity of Mini Programs, while conducting content review, the Mini Program codes will be checked for similarity, so as to detect plagiarism of Mini Program codes. In the related art, code similarity detection tools are usually used for cod...
