Cloud platform interface multistage flow control method under multi-cloud management scene

The invention belongs to the technical field of multi-cloud interface communication, and particularly relates to a cloud platform interface multi-level flow control method under a multi-cloud management scene, which comprises the following steps of: S1, defining flow control rule entities of a cloud platform, a tenant, a user and an operation level; s2, creating a user-defined annotation, and marking a flow control label in an entry of the resource operation; s3, setting the custom annotation on the method for marking that the method needs to be subjected to flow limiting according to the flow control burying point; and S4, after flow control point burying is carried out in the method, defining a point burying scanner, and uniformly scanning all methods which have been subjected to user-defined annotation point burying, so that the flow control rule configured in the S1 is bound with the method. According to the invention, the problem that a current traffic control framework can only implement simple traffic
