How to implement scheduled tasks and planned tasks through the Webman framework?

Webman is a lightweight Web framework developed based on Go language. It provides a simple way to implement scheduled tasks and planned tasks. This article will introduce how to use the Webman framework to implement timed tasks and scheduled tasks, and provide corresponding code examples.

Before using the Webman framework, you need to install Webman first. Webman can be installed through the following command:

go get github.com/henrylee2cn/webman

After the installation is complete, we can start writing code. The following is a sample code that uses the Webman framework to implement scheduled tasks:

package main

import (
    "fmt"
    "github.com/henrylee2cn/webman"
    "github.com/henrylee2cn/webman-std/jobman"
    "time"
)

func main() {
    webman.Web().JobMan(jobman.NewDefault())

    // 注册一个每5秒执行一次的定时任务
    webman.Web().CronFunc("@every 5s", func() {
        fmt.Println("执行定时任务：每5秒执行一次")
    })

    // 注册一个每分钟执行一次的计划任务
    webman.Web().CronFunc("0 * * * * ?", func() {
        fmt.Println("执行计划任务：每分钟执行一次")
    })

    // 启动Web服务
    webman.Web().Run()
}

In the above code, we first passwebman.Web().JobMan(jobman.NewDefault()) Initialize Webman's JobManager. Then use the webman.Web().CronFunc() function to register scheduled tasks and scheduled tasks. Among them, the first parameter is a cron expression, used to specify the execution rules of the task; the second parameter is a function, indicating the content of the task to be executed.

In the above example, we registered a scheduled task that executes every 5 seconds and a scheduled task that executes every minute. In the task's execution function, we simply print a message.

Finally, we use webman.Web().Run() to start the Web service. By running the above code, we can see on the console that scheduled tasks and scheduled tasks are executed according to the set rules.

In addition to scheduled tasks and scheduled tasks, the Webman framework also provides many other powerful functions, such as routing management, middleware, request processing, etc. These features can help us build and manage web applications more conveniently.

To sum up, using the Webman framework can easily implement scheduled tasks and planned tasks. With a few simple lines of code, we can implement various tasks that need to be executed regularly. I hope this article will help everyone understand and use the Webman framework.
