As shown in fig. 1, the present invention provides a method for discovering network microservices, comprising the following steps:
101, the service provider packages the information of the manufactured micro-service function content, data content, QOS content and the like into an XML micro-service description file according to the standard of a service registry and issues the XML micro-service description file to the network;
102, a service requester packages information such as required micro-service function requirements, performance requirements, safety requirements and the like into an XML service requirement file according to the specification of a service registration center and issues the XML service requirement file to a network;
103, when the node capable of analyzing the XML service requirement file obtains the service requirement information, starting to perform content matching on the XML file content and the XML microservice description file of the node, and returning microservice link information to the service requester after the matching is successful;
104, a network node meeting the service registry specification in the routing process of the microservice information identifies the microservice XML file and checks whether the microservice can be executed, and if so, caches the microservice at the network node.
In step 101:
the service provider needs to describe information including but not limited to the provided micro service function information, description service provider information, description micro service application information, micro service deployment information, description micro service performance information, description micro service QOS information, etc.;
micro-services include, but are not limited to, service installation files, service operating environments, and service data;
the installation files, the service operation environment and the service data of the micro-service can be separated and support remote calling;
the development language, the operating environment and the service data of the micro service include but are not limited to the current mainstream development language, the operating environment and the database or other data storage forms.
In step 102:
the service requester needs to describe, but is not limited to, required function information of the micro service, required call information of the micro service, use information of the micro service, evaluation information of the user, and the like.
The service requester can request the micro service in two ways, one is to search and call the service in the service registration center, and the other is to directly issue the broadcast information of the micro service request and directly communicate with the service provider, so as to use the micro service.
In step 103:
the service requester and the service provider match the contents in the XML service description file through the XML service requirement file issued by both, not only through calculation matching in service registration and pointing through IP.
In step 104:
the computing power and data power of the microservice are routed through the matched content, not just directed or scheduled through the service registry;
the micro-service can perform service executable environment detection on the passing nodes in the routing process, and cache the micro-service in different nodes after the detection is successful.
In steps 101-103:
the service registration center formulates a service description specification in the network, but does not intervene in a service routing process actively, and simultaneously needs to describe information including but not limited to service calling information, micro-service evaluation information, micro-service authentication information, micro-service safety information and the like;
the service registration center, the service provider and the service requester follow the same micro-service description specification based on the XML format;
the service provider broadcasts the XML service description file in the network according to the standard, or actively sends the XML service description file to the service registration center;
the service registration center can automatically capture an XML service description file meeting the specification in the network;
the service registration center automatically analyzes the XML service description file, detects the corresponding micro service according to the file description and modifies the XML service description file for rating and authentication;
the service requester issues the micro service request to an XML service requirement file conforming to the specification in the network, or can call an XML service description file required by service search of the service registry, or automatically acquires the XML service description file of the required micro service in the network according to the specification.
Fig. 2 is a block diagram of a method for discovering microservice according to an embodiment of the present invention. The service registry is used for establishing a microservice description specification, and the service requester and the service provider need to compile and release an XML service requirement file and an XML microservice description file according to the service specification; in principle, the service registration center does not interfere with the routing and caching process of the micro-service, but the service requester can also directly carry out service retrieval through the service registration center; the service registration center can capture the service use information related to the service requester and the service provider, and edit part of information in the micro-service description XML file according to the requirement; the XML file issued by the service requester is matched with the XML file provided by the service provider according to the rules provided by the service registry, the matching includes but is not limited to functional content, performance content, data structure, security, QOS index and the like, the XML requirement description file can be matched with a plurality of XML service description files and returns the micro-service to the service requester, and the micro-service is routed after the connection is successful; in the micro-service routing process, the micro-service is cached when passing through the identifiable and executable network nodes.
Fig. 3 is a flowchart of a service discovery process of a network microservice discovery method according to an embodiment of the present invention. Firstly, a service requester compiles an XML service requirement file according to the rule of a registration center, and the service requester issues service requirement XML description to the whole network, wherein the service requirement XML description comprises the requirements of service functionality, non-functionality, a data structure, an operating environment and the like of the service requester; the service provider compiles a microservice XML description file according to the rules of the service registry, wherein the microservice description, the non-functional description, the QOS description, the security description and the like of the service provider are included; then, the nodes in the network following the rules of the service registration center can identify the received service requirement XML description file, analyze the received service requirement XML description file, match the service requirement XML description file with the micro service XML service description file of the nodes, and if the matching is successful, a success message is returned to the service requester and corresponding micro services are provided; the micro service can identify the micro service XML description file of the passing node in the process of routing to the service requester, and if the running environment can support backup, the micro service can cache and run a copy in the node; the service registration center can collect service requirement XML files of service requesters in the network and micro service XML description files of service providers, and can complete two functions, wherein one function is as an integrated controller, a micro service provider is appointed for the service requesters when the service requesters actively send service requirements to the service registration center, and the other function is to evaluate the service quality of micro services and modify the content of corresponding parts of the XML micro service description files.
By the technical scheme provided by the invention, the inquiry and calling problems of the mass micro-services in the network environment are solved, the network micro-service discovery method is provided, the mutual identification, routing and caching problems among the micro-services are realized by two modes of interconnection and centralized management, and the usability of the micro-services in the network is improved.
