In the design and implementation of a distributed technology platform, a timing task is basically an indispensable service for managing the task distribution and execution of the whole platform. At present, http or https is used as a communication protocol to trigger and execute a timing task on an internet technology platform, and the scheme is relatively simple to implement.
However, most of the existing distributed systems are implemented by micro service architectures, and most of the platforms under the micro service architectures implement data transmission between the micro service architectures by using an RPC protocol and asynchronous messages. At this time, the timed task service must support RPC protocol or asynchronous message, or the micro-service architecture supports http/https protocol. Under the condition that the number of micro service architectures is large and the timing task is large, huge workload and maintenance complexity are brought when any party supports the protocol of the other party.

Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Example one
The embodiment provides a method for implementing a timing task based on an asynchronous message, as shown in fig. 1, the method includes the following steps:
s100, receiving a timing task by a timing task message distribution service to a timing task management service;
s200, after receiving the timing task, the timing task message distribution service suspends the http/https request and converts the timing task into an asynchronous message;
s300, the timed task message distribution service sends asynchronous messages to an asynchronous message service;
s400, the asynchronous message service forwards the asynchronous message to the microservice;
s500, after receiving the asynchronous message, the micro service executes corresponding business according to the content of the asynchronous message.
In this embodiment, the timed task message distribution service and the timed task management service are interfaced via an http/https protocol.
Specifically, the timed task message distribution service and the timed task management service are in butt joint through an http/https protocol, and the timed task sent by the timed task management service is received. After receiving the timing task, the timing task message distribution service firstly suspends the http/https request, does not return immediately, and returns the http/https request after waiting for receiving a corresponding execution result or waiting for overtime. The timed task message distribution service translates (the format of) the timed task into asynchronous messages (the format) of the microservice owned service. The timed task message distribution service sends the asynchronous message to an asynchronous message service. The asynchronous message service forwards the asynchronous message to the microservice, and simultaneously the asynchronous message service monitors the execution result return message after the message processing in real time. After receiving the asynchronous message, the micro-service executes corresponding service according to the content of the asynchronous message.
As shown in fig. 2, the method further comprises the steps of:
s600, after the micro service executes the corresponding service, returning an execution result to the asynchronous message service, wherein the execution result is in an asynchronous message format;
s700, the asynchronous message service forwards the received execution result to a timing task message distribution service;
s800, after receiving the execution result, the timed task message distribution service returns a suspended http/https request to the timed task management service according to the execution result;
s900, if the asynchronous message service does not receive the execution result within the preset time, returning an execution task overtime message to the timed task message distribution service;
s1000, the timed task message distribution service sends an executed task overtime message to the timed task management service, and the timed task management service processes the executed task overtime message;
s1100, if the asynchronous message service receives a task execution error message, forwarding the message to a timed task message distribution service;
s1200, the timed task message distribution service sends the executed task error message to the timed task management service, and the timed task management service processes the executed task error message.
Specifically, after the micro service executes the corresponding service, an execution result is returned to the asynchronous message service, and the execution result (format) is also in the asynchronous message format. The asynchronous message service forwards the execution result to the timed task message distribution service. And after receiving the execution result, the timed task message distribution service returns a suspended http/https request to the timed task management service according to the content of the execution result. At this point, a complete timed task process is completed.
Further, if the asynchronous message service does not receive the execution result returned by the micro service within the preset time, returning an execution task overtime message to the timed task message distribution service. The timed task message distribution service sends the executed task overtime message to the timed task management service, the timed task management service processes the executed task overtime message, and the executed task overtime message is displayed at a timed task manager end or the timed task is automatically retransmitted, which is specifically determined by the timed task requirement.
Further, if the asynchronous message service receives an executive task error message, the executive task error message is forwarded to the timed task message distribution service. The timed task message distribution service sends the executed task error message to the timed task management service, the timed task management service processes the executed task error message, and the executed task error message is displayed at a timed task manager end or the timed task is automatically retransmitted, which is specifically determined by the timed task requirement.
It should be noted here that, for the case where the asynchronous message of the same timing task is sent by the asynchronous message service for multiple times, the process is still handled in a manner of solving idempotency in the distributed system, and no new logic or concept is added.
Example two
The embodiment provides a system for implementing a timing task based on an asynchronous message, as shown in fig. 3, the system includes: the system comprises a timing task management service, a timing task message distribution service, an asynchronous message service and a micro service which are connected in sequence.
The timed task message distribution service is used for receiving a timed task to the timed task management service, converting the timed task into an asynchronous message after receiving the timed task, and sending the asynchronous message to the asynchronous message service;
an asynchronous message service for forwarding asynchronous messages to the microservice;
and the micro service is used for executing corresponding services according to the content of the asynchronous message after receiving the asynchronous message.
Referring to FIG. 3, it is worth explaining here that the asynchronous message service may connect a plurality of microservices, which communicate with each other via the RPC protocol. Under the condition of more timing tasks, a plurality of micro services ensure that a plurality of corresponding services can be executed simultaneously.
In this embodiment, please refer to the description of the method for implementing a timing task based on an asynchronous message in the first embodiment in the working process of the system for implementing a timing task based on an asynchronous message, which is not described herein again.
