The invention relates to the technical field of distributed
system security and intelligent operation and maintenance, in particular to an API full-life-cycle intelligent treatment method and
system based on multi-
modal data
perception and a blood relationship atlas, and the method comprises the steps: S1, collecting network traffic in a non-intrusive mode, automatically discovering an API, extracting
metadata features, and generating an API change event; s2, performing semantic analysis on the API
metadata based on a
natural language processing technology, calculating a sensitivity
score, and performing marking alarm on a high-risk interface; s3, constructing an API blood relationship map, and carrying out change
influence analysis and
risk assessment based on the map; s4, risk
simulation is carried out on API changes based on flow playback, and plan changes are tested in a layered sandbox environment; and S5, automatically generating a document conforming to an
open API specification based on the API
metadata, and synchronously updating in real time. All links are connected in series to form a closed-loop governance
system through the event-driven engine, automatic and intelligent governance of API assets is achieved, and the safety, stability and operation and maintenance efficiency of the system are improved.
