Data calling method and device and computer readable storage medium

Abstract

The invention provides a data calling method and device and a computer readable storage medium. The data calling method comprises the steps that an RPC client obtains a current client handle in current data calling parameters; the RPC client searches a current universal unique identification code corresponding to the current client handle in a plurality of pre-constructed second key value pairs according to the current client handle; the RPC client side sends the found current universal unique identification code to the RPC server side; the RPC server side searches a target server side handle corresponding to the current universal unique identification code in a plurality of pre-constructed first key value pairs according to the current universal unique identification code; and the RPC server calls data corresponding to the target server handle according to the searched target server handle, so that the handle in the RPC client corresponds to the handle of the RPC server, handle correspondence between different physical machines is realized, and handle calling is realized.

Description

technical field [0001] The present application relates to the technical field of remote procedure call, in particular, to a data call method, device and computer-readable storage medium. Background technique [0002] RPC (Remote Procedure Call, Remote Procedure Call), adopts client / server mode. A requester is a client, and a service provider is a server. First, the client initiates a local call, and the data directly enters the local caller function for data packaging, and then the packaged data is passed to the server by the RPC framework through the network call package. On the server side, the process keeps listening until the network call packet arrives. When the information arrives, the packaged data is passed to the provider function to unpack, call the service and execute, then package and pass the returned result data to the RPC framework to return to the client, and then wait for the next call information, and finally, the client The caller receives the return re...

AI Technical Summary

Problems solved by technology

[0006] In the data call method designed above, this scheme establishes the connection between the client handle and the server handle through the universal unique identification code, so that the client handle can point to the corresponding server handle, thus solving the current problem of directly connecting the client The handle is sent to the RPC server, which brings about the problem that the RPC server cannot use the client handle for data calls, and then realizes the unique correspondence of a certain memory address of different physical machines (RPC server and RPC client), thus So that when the callee needs to use the handle, it can be called smoothly
