System calling method, device and equipment and readable storage medium

Abstract

The invention discloses a system calling method, device and equipment and a readable storage medium, relates to the technical field of Internet, and aims to call a timing scheduler only in a timeout situation, save a large amount of resources of the timing scheduler and reduce system calling. The method comprises the following steps: sending a processing request to a second system, and counting the waiting time waiting for the second system to return a processing result; when it is detected that the waiting time length is larger than a timeout threshold value, registering a timing task in thetiming scheduler, returning a failure response to the upstream, and the timing task at least comprising preset time and a recovery interface; receiving a call of the timing scheduler to the recovery interface after a preset time, calling a query interface of a second system based on the recovery interface, and querying and returning a processing result by the second system; and if the received processing result indicates that the calling is successful, calling a reverse interface of the second system, and calling the second system based on the reverse interface to withdraw the recovery data corresponding to the processing result.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a system call method and device. Background technique [0002] With the rapid development of Internet technology, many softwares have emerged and become an indispensable part of people's life and work. Software is usually supported by the software system it carries. However, due to the complexity of its internal logic, large-scale software systems are often divided into multiple subsystems that perform specific functions in accordance with the principle of high aggregation and low coupling during the development process. The processing of a business often requires mutual calls and division of labor between multiple subsystems to achieve the desired results. Taking code scanning payment as an example, after the merchant successfully scans the user's payment code, the subsystems involved in the background include the decoding subsystem , user verification subsystem, protocol ...
