In this embodiment, the annotation parser may obtain corresponding values of the target attributes according to the target attributes used for generating the token in the annotation information, if there are a plurality of target attributes, the corresponding values of the target attributes are spliced according to a splicing rule in the token generation policy, if there is only one target attribute, splicing is not required, further, if the token generation policy further includes an encryption algorithm, the corresponding values of the target attributes are encrypted according to the encryption algorithm, and if there is no encryption algorithm, encryption is not required, and the token is finally obtained.

In this embodiment, an interceptor is set on the server, and after receiving the interface call request, the server can intercept the interface call request by the interceptor and perform interface idempotent judgment according to the interface call request and a preset idempotent rule. Optionally, the interceptor may be a custom JSF interceptor, where JSF (jingdong Service framework) is a jingdong Service framework and a high performance Service framework independently developed by jingdong. Of course, it is also possible to replace JSF with Dubbo, a high performance and excellent service framework sourced by the company arizoba.
Optionally, the specific process of the interface idempotent judgment may be: inquiring result data corresponding to the token in a database according to the token through an interceptor; if the result data corresponding to the token can be inquired, directly returning the result data to the client; or if the result data corresponding to the token cannot be inquired, directly calling the target interface of the server according to the interface calling request, returning the result data output by the target interface of the server to the client, and caching the result data in the database. The DataBase may be any DataBase, such as a Remote Dictionary Server (Redis) or a JimDB (Jingdong In Memory DataBase, kyoto Memory DataBase), which is a clustering scheme for the native Redis (2.8).
Optionally, interface idempotency judgment needs to be performed on all the interfaces configured on the interceptor in advance, or interface idempotency judgment needs to be performed on part of the interfaces, and an interface list needing the interface idempotency judgment needs to be preset for part of the interfaces, so that when the interceptor performs the interface idempotency judgment according to an interface calling request and a preset idempotency rule, the interceptor firstly obtains interface information of a target interface of the service end, and then judges whether the interface calling request needs to perform the interface idempotency judgment according to the interface information and the preset interface list needing the interface idempotency; if the idempotent judgment is needed, the interface idempotent judgment is carried out through an interceptor according to an interface calling request and a preset idempotent rule; or if the idempotent judgment is needed, the target interface of the server side is called directly according to the interface calling request.

In this embodiment, the security level of the interface is realized through the authority code, the reliability of the interface is improved, and meanwhile, the subsequent judgment of the power of the interface and the like can be stopped under the condition that the authority check does not pass, so that the consumption of server resources is avoided.
On the basis of any of the above embodiments, optionally, the interceptor may further determine whether the token format is legal, for example, whether the token format satisfies a format agreed with the server, for example, whether the token is defined as first of a method name, whether a token generation algorithm is reasonable, or the like; if the token format is illegal, returning error information to the client, finishing the subsequent interface power and the like judgment, and caching the token in the database so as to be convenient for directly intercepting when receiving the token next time and prevent from consuming server resources. And if the token format is legal, the subsequent interface power and the like are continuously judged.
