in the cluster service module, an API gateway service acquires micro-service request information of an external mobile terminal through a network and distributes the micro-service request information to corresponding data micro-services;
and the data micro service acquires and processes the stored service information, and returns the processed service information to the external mobile terminal corresponding to the micro service request.
7. The distribution network automation host station mobile application service management system based on the micro service architecture as claimed in claim 6, wherein the data micro service includes an authority micro service, which performs user authentication by using a token authentication method of OAuth2+ JWT in response to receiving the user login request message, and further issues a token to a corresponding external mobile terminal after the authentication is passed.
8. The micro-service architecture based distribution network automation master station mobile application service management system of claim 6, wherein the data micro-services further comprise one or more of load micro-services, feeder micro-services, terminal micro-services, real-time alarm micro-services, graphical micro-services and operation and maintenance micro-services.
9. The distribution network automation master station mobile application service management system based on the micro-service architecture as claimed in claim 6, wherein each micro-service is configured to be backup and load balancing by the server cluster, so that when one micro-service cannot be called, normal operation of the service is realized by calling the backup of the micro-service; the load balancing adopts a polling calling strategy.
10. The distribution network automation master station mobile application service management system based on the micro service architecture as claimed in claim 6, wherein the cluster service module further comprises a fusing service implemented by Hystrix for forcing a plurality of subsequent calls to fail quickly when any one service of a hierarchy fails.
