Abstract

The invention provides a static source code scanning method, a device, a computer device and a storage medium, wherein, the method comprises the following steps of: obtaining an abstract syntax tree corresponding to the source code to be scanned; parsing code information in the abstract syntax tree to generate an execution chain set corresponding to the abstract syntax tree, wherein each executionchain in the execution chain set corresponds to an execution path in the source code respectively; each execution chain in the set of execution chains is traversed to determine whether the source code contains defective code. Through the method, the defect code can be determined only by analyzing each execution chain, the analysis process is simple and reliable, the analysis efficiency is improved, and the technical problem that the source code is converted into a corresponding control flow chart first in the prior art, and then the control flow chart is traversed and analyzed to realize thestatic scanning of the source code, and the analysis process is complex and the efficiency is low is solved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a static source code scanning method, device, computer equipment and storage medium. Background technique [0002] Static source code scanning is one of the software application security solutions mentioned by people in recent years. Defects in the code to ensure software quality. [0003] At present, in related technologies, when statically scanning the source code, the source code is converted into a control flow graph in various ways, and then various algorithms are used to traverse and analyze the control flow graph to detect defects in the source code. In this static scanning method, the analysis process is complicated, and corresponding traversal programs need to be written for different analysis targets, which is inefficient. Contents of the invention [0004] This application aims to solve one of the technical problems in the related art at least...
