Description
Technical Field
The invention relates to the technical field of service governance, in particular to a distributed service governance method, a system and a computer readable medium thereof.
Background
Service governance, also known as SOA governance, refers to the process used to manage the adoption and implementation of SOAs. The SOA is a coarse-grained and loosely-coupled service architecture, and services communicate with each other through a simple and accurately defined interface without involving a bottom programming interface and a communication model. SOA can be seen as a natural extension behind the B/S model, Web Service technology. The technical cognition of most software design and developers on SOA and Service management mainly stays on the technologies and specifications of Web Service, ESB bus and the like, and the technology does not fall on the ground fully in software development. On the service end side, the internal network security of the company is considered, the machine room divides the server into different areas, and the networks between the different areas cannot be directly connected, for example, a firewall is added between the DMZ isolation area and the intranet area, but the general architecture of the company software system adopts a service console mode, which requires that the different network areas can be mutually called on the premise of ensuring the security. In the traditional mode, middleware proxy network services such as Nginx and the like are built between DMZ and an intranet, and the architecture is complex.
Through retrieval, patent document CN110233886A discloses a high-availability service management system for massive micro services and an implementation method thereof, where the system includes a server, a client and an address management end, and the method includes the steps of: the service provider registers the service; the server side performs service synchronization; the service provider renews the lease and expires; the service caller calls the service; when the address of the server changes, the address of the server is synchronized between the client and the server. Although the prior art obviously ensures high availability of the service registration center under the scene of massive micro-services and uses the consistent hash algorithm to determine the corresponding relation between the client and the server, the prior art has the disadvantage that the mutual calling of the services can be realized only by building a plurality of middleware services.
Therefore, it is necessary to develop a service management framework that can implement the function of mutual service invocation without building middleware service, so as to solve the existing complex technical problem.

The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
As shown in fig. 1, the present invention provides a distributed service management method, which includes the following steps:
step S1: the server side registers the opened service information to a registration center, and simultaneously issues two layers of IP addresses aiming at one service information, wherein the two layers of IP addresses comprise an external IP address and an internal IP address, the external IP address refers to an agent IP address, and the internal IP address refers to a local IP address. Further, the service information includes application programming interface information including address, port and parameter information of the application programming interface.
Step S2: and the caller subscribes the service information, analyzes the parameter information of the subscription service information and marks a plurality of IP addresses issued by the server. The caller comprises a client in an internal network or a client in an external network, and the caller allows the selection of the adaptive IP address for service communication according to the current network environment.
Furthermore, the calling party loads the configuration parameters for marking, the IP address of the calling party is not marked by default, and when the calling party accesses the proxy IP address, the proxy IP address is marked, and then the communication between services can be directly carried out through the marked proxy IP address.
Furthermore, if the service information subscribed by the caller is not registered in the registry, the client is allowed to send a service request to the server, the server registers the service information corresponding to the service request in the registry, and the registry sends the service node update notification information to the client, so that the client can subscribe the newly registered service information.
Step S3: and the calling party assembles the service message according to the parameter information.
Step S3.1: the calling party decomposes the parameter information into system parameters and service parameters, wherein the system parameters refer to information such as IP addresses and ports, and the service parameters refer to marking parameters.
Step S3.2: and selecting system parameters of the optimal service by adopting a preferred random algorithm, and assembling the information of the service requesting node.
As shown in fig. 2, the preferred random algorithm is that a service node is set under a root node, a plurality of child nodes are set under the service node, and the presentation situations of each child node are different, such as: the sub-node a1 represents normal service information, the sub-node a2 represents gray-scale service information, the sub-node A3 represents abnormal service information, and the like, from which system parameters of an optimal service need to be screened out.
Step S4: and the calling party transmits the service message to the server to complete service interaction.
The invention also provides a distributed service management system, comprising:
the server side: the server side registers the opened service information in a registration center and simultaneously issues a plurality of IP addresses;
the client call end: the calling party subscribes the service information, analyzes the parameter information of the subscription service information and marks a plurality of IP addresses issued by the server, and the calling party assembles a service message according to the parameter information and transmits the service message to the server to complete service interaction;
the agent module: and an agent module is arranged between the client calling end and the server end, and the agent module is used for directly realizing the matching of IP addresses and carrying out information interaction.
Further, the proxy module is divided into a client proxy module and a service proxy module, and the client terminal calls the registration service on the client proxy module, that is, the client proxy module does not actually perform the registration service, but calls the remote service through the client proxy module. The client agent module then sends the binary request to the service agent module over the network by packaging the parameter information. Then the service agent module analyzes the parameter information and sends a request to the server to call the registration service; if the registration service on the server side is called, returning a calling result to the service agent module; then, the service agent module packs the calling result and sends the binary result to the client agent module through the network; and finally, after the client agent module analyzes the calling result, returning the calling result to the client.
Preferably, when a certain service running in production needs to issue a new function, in order to ensure the security of the client, a small part of the new function is tried out according to the condition of the client, the client supports the caller to embed a special mark in the calling process to distinguish different user requests, and the server selects a route to the new function or the old function according to the special mark.
