Problems solved by technology

[0004] Since the newly added interface is an enhancement of the function of the original old interface, when using IDL to describe the new interface, it will cause cumbersome processing due to the redundant code defining the new interface when calling, making maintenance inconvenient
And it will make the system upgrade a lot of work

Embodiment Construction

[0021] The specific implementation manners of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] In the prior art, since the newly added interface is an enhancement of the function of the original old interface, when using IDL to describe the new interface, there needs to be a large number of defined codes identical to the old interface in the code defined for the new interface. Therefore, there is a large amount of repeated code for the definition of the new interface, so when calling, it is cumbersome to deal with due to the code redundancy of defining the new interface, and it is inconvenient to maintain. Moreover, if the software on the server side is upgraded, the software on the client side should also be upgraded together, so that the client side can call the interface according to the agreed method matched with the server side. Therefore, the existing technology will cause a large w...

Abstract

The embodiment of the invention discloses an interface invoking method of a distributive system, comprising the steps of: receiving an interface invoking request message sent by a client; judging whether the interface invoking request message comprises numerical values of default parameters of an interface description language IDL, if not, acquiring the default value of the default parameters of the IDL from pre-stored information; using the acquired default value of the default parameters of the IDL to invoke interfaces requested by the client. Moreover, the invention also discloses a devicefor invoking interfaces in a distributive system. The invention, for old clients that exclude the numerical values of default parameters of the IDL, uses the pre-stored default values of the IDL to invoke the interfaces so that the upgraded system is still able to be compatible with the old clients without upgrade, accordingly, the invention prevents the situation that all the components in the entire distributive system are in need of linking upgrade in virtue of the upgrade of the server, accomplishing light-weight upgrade for the components.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device for calling an interface of a distributed system. Background technique [0002] A distributed system enables clients in the system to use remote services like local servers, and has the advantages of incremental scalability and resource sharing. At present, most of the distributed systems describe interfaces between components in the distributed system through Interface Description Language (IDL), and through the interfaces, methods (Functions) corresponding to components are called to realize corresponding functions. In order to support component upgrades, new interfaces are usually generated in the system for newly upgraded components. In the prior art, when a component is upgraded, a new interface corresponding to the new component needs to be generated, and at the same time, the new interface needs to be described using IDL. Since the upgraded comp...
