Description
Technical Field
The present invention relates to computer network technology, and in particular, to a service invocation method and a gateway.
Background
At present, a large website or a large system is realized by adopting a service oriented architecture component model (SOA), the whole system is subdivided into a plurality of subsystems by the project of the same language, and the subsystems are interacted through a service calling framework, so that the efficiency of the system is improved. However, when the external system is a cross-language system and the present system is a cross-language system, the current problem cannot be solved only by a service invocation mode, and at this time, each service subsystem needs to be published as webservice or other similar services for the external system to invoke. Thus, a WebService interface service that separately writes calls for calls that provide external systems is needed.
Because the number of interfaces for calling the current system by the external system is large in the prior art, the complexity of system development and use is inevitably increased by adopting the method of issuing the WebService interface service for each interface for external system calling. At present, a scheme capable of effectively solving the problems is not provided.
Disclosure of Invention
In view of the above, the main objective of the present invention is to provide a service invocation method and a gateway, which can implement service invocation between cross-language systems and are easy to develop and use.
In order to achieve the purpose, the technical scheme provided by the invention is as follows:
a service invocation method, comprising:
calling a service request direction to provide a system of a service and sending a hypertext transfer protocol Http parameter, wherein the Http parameter carries calling service information;
the gateway of the system for providing the service analyzes the received Http parameter by using Http protocol to obtain the calling service information, calls a service framework Application Programming Interface (API) through the system according to the calling service information, calls a corresponding service, and returns a calling result to the calling service requester.
A service invocation gateway, comprising:
the analysis module is used for carrying calling service information after receiving the Http parameter sent by the calling service request party, and analyzing the received Http parameter by using the Http protocol to obtain the calling service information;
and the calling module is used for calling a service framework Application Programming Interface (API) through the system according to the calling service information, calling corresponding services and returning a calling result to the calling service requester.
An apparatus for service invocation, comprising:
a memory; and
a processor coupled to the memory, the processor configured to perform any of the methods described above based on instructions stored in the memory.
A computer-readable storage medium, on which a computer program is stored which, when executed by a processor, implements the method of any of the above.
In summary, the service invocation method and the gateway provided by the invention are based on the Http protocol, and are responsible for converting Http parameters of service invocation of each external system into corresponding service invocation by using one gateway, so that a seamless connection result of the invocation between cross-language systems can be achieved. Therefore, WebService interface service for independently writing and calling for calling of the external system is not needed, and complexity of system development and use can be greatly reduced.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The core idea of the invention is as follows: for each application system, a gateway is utilized, based on an Http protocol, to process Http requests of service calls of each subsystem in the external system to the external system, specifically, the gateway calls a corresponding interface service of the external system according to call service information in the Http requests, and returns a result to the external system. Therefore, each interface does not need to be issued into a WebService interface service to be called by an external system, and further the WebService interface service which is independently written and called for calling the external system is not needed, so that the complexity of system development and use can be greatly reduced.
Fig. 1 is a schematic flow chart of a method according to an embodiment of the present invention, as shown in fig. 1, the embodiment mainly includes:
In this step, the service calling requester does not need to call the service in the form of WebService interface call, but only needs to notify the system providing the service of the calling service information in the form of Http parameter. Therefore, on one hand, during system development, developers do not need to write and call the WebService interface service independently for providing external system calls, and on the other hand, during use, a call service requester does not need to master a large amount of WebService interface information, so that complexity of service call development and use can be greatly reduced.
Preferably, the calling parameter information includes: the name of the service, the name of the method, the parameters, and the name of the group that are invoked.
And step 102, the gateway of the system for providing the service analyzes the received Http parameter by using Http protocol to obtain the calling service information, calls a service framework API through the system according to the calling service information, calls a corresponding service, and returns a calling result to the calling service requester.
In this step, the system for providing services uses a gateway to perform unified processing on the call request of the external system, and analyzes corresponding call service information from the Http parameter sent by the call service requester based on the Http protocol, and then uses the system call service framework API to directly call corresponding services according to the call service information, and returns the result to the caller. Therefore, when the system interface is developed, a set of external system calling interfaces do not need to be developed independently, and cross-language service calling can be realized by directly calling and converting through the gateway.
In this step, the specific method for parsing out the calling service information based on the Http protocol and the specific method for directly calling the corresponding service by using the system calling service framework API are known to those skilled in the art, and are not described herein again.
In practical application, if the service provided by the system is a service deployed by a cluster, the gateway can route the service to different clusters according to the incoming parameter data and the routing information configured in the routing configuration table.
Fig. 2 is a schematic structural diagram of a service invocation gateway corresponding to the above method, and as shown in fig. 2, the gateway includes:
the analysis module is used for carrying calling service information after receiving the Http parameter sent by the calling service request party, and analyzing the received Http parameter by using the Http protocol to obtain the calling service information;
and the calling module is used for calling a service framework Application Programming Interface (API) through the system according to the calling service information, calling corresponding services and returning a calling result to the calling service requester.
Preferably, the calling parameter information includes: the name of the service, the name of the method, the parameters, and the name of the group that are invoked.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
