Task processing method and equipment based on asynchronous callback

Abstract

The purpose of the invention is to provide a task processing method and task processing equipment based on asynchronous callback. compared with the prior art, the method comprises the steps of acquiring a syntax tree of a to-be-processed task, wherein the syntax tree includes a node and a node association relation; executing the node in the syntax tree based on the node association relation; when the executed node is provided with a predetermined asynchronous mark, sending an asynchronous processing command to an asynchronous call object, and returning a father node of the node with the predetermined asynchronous mark to continuously process the task; and when feedback from the asynchronous call object is received, returning the node with the predetermined asynchronous mark. Thus, the task processing time based on asynchronous callback is shortened and low delayed response can be still achieved in the case of processing complex service logic.

Description

technical field [0001] The present application relates to the computer field, in particular to a task processing technology based on asynchronous callback. Background technique [0002] Asynchronous calls have a wide range of applications in application frameworks, and specifically refer to multi-threaded situations. It is closely related to Windows' message loop mechanism, message response, message queue, event-driven mechanism, and observer pattern in design patterns. In the single-threaded mode, the computer is a strictly von Neumann machine. When one piece of code calls another piece of code, it can only use synchronous calls. Continue to execute. With the support of multi-threading, asynchronous calls can be used. The caller and the called party can belong to two different threads. After the caller starts the called party thread, it continues to execute subsequent codes without waiting for the other party to return the result. After the called party completes the exe...

Problems solved by technology

[0003] The advantage of asynchronous callback or event-based programming is that it makes full use of thread computing resources and greatly improves concurrent throughput. However, for most programmers who are accustomed to sequential logic programming, programming is very difficult because it does not conform to the habit of thinking. For Code review and troubleshooting are also difficult

It is difficult for the current programming language system to find a way to code in traditional sequential logic while enjoying the benefits of asynchronous processing, and it can also support parallel calls to remote services or asynchronous processing codes to speed up business logic processing

However, there is still room for improvement in the existing mainstream languages. It reduces the difficulty of programming in terms of formal semantics and reduces the task processing time based on asynchronous callbacks. It can still achieve low-latency responses when processing complex business logic.
