and adaptively updating the fusing rate based on the total request amount data and the successfully processed request amount data.
As a preferable technical scheme, the fusing rate is inversely proportional to a request successful processing proportion, and the request successful processing proportion is a ratio of the successful processing request amount data to the total request amount data.
As a preferable technical scheme, the fusing rate is updated by adopting the following formula:
wherein rate is the fusing rate, max () is a maximum function, requests are total request data, accept is successful processing request data, and K is a fusing coefficient.
As a preferable technical scheme, the fusing coefficient is a preset constant.

(2) Fuse state switching smoothing: and dynamically controlling the fusing rate, increasing the successful request quantity along with the recovery of abnormal services, naturally reducing the fusing rate, and smoothly rising the release request, thereby avoiding secondary service fusing caused by instantaneous closing of the fusing state.
(3) Switching the fusing state in real time: by adopting the self-adaptive fusing method, the time-round-robin-based fusing state switching in the prior art is abandoned, the real-time switching of the fusing state is realized, and the access request is timely accessed after the service is recovered to be normal.

FIG. 1 is a flow chart of an adaptive API gateway fusing method in an embodiment.
Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

As shown in fig. 1, this embodiment provides an adaptive API gateway fusing method, which includes the following steps:
and step S1-S2, the client sends a request.
And S3-S4, the fuse releases the request according to the fusing rate, if the server receives the request but fails to respond, the fuse is triggered, the access request is refused, and the requests are ended in +1.
And step S5-S7, the server receives the request and responds successfully, and the requests are +1 and the acceptors are +1.
S8-S9, recalculating the fusing rate based on the fusing coefficient K and an adaptive formula, wherein the adaptive calculation formula is as follows:
wherein, requests: and setting initial values according to the service scene according to all the request quantities.
accept: and setting initial values according to the service scene for all successful request quantities.
rate: the fusing rate fuses the request with a certain probability.
In the request process, if the fusing rate is larger than a preset value, an alarm signal is sent out. The update rule of the fusing rate is as follows: the interval time is greater than a preset value or the increase in total requested amount data since the last update is greater than a preset value. In addition, the fusing rate may be updated after the request is received and before the fusing determination.
An existing automatic fusing strategy based on the micro-service fuse is used for setting a Close/Open/HalfOpen three-section interception mechanism according to service states. All requests can be intercepted in the Open state, so that server resource waste is caused, and when the HalfOpen state switches the Close state, all requests are released, so that the back-end service can be flushed again, in addition, the service checking round-robin time is fixed, and the multi-service scene requirement is difficult to meet.
