Question

我正在编写一个小型应用程序，以在社交网络上执行自动发布。

我的意图是，用户可以通过Web界面在特定时间创建帖子，而bot可以检查预定的新帖子并执行。

我在Go上使用例程和通道时遇到麻烦。

我将在下面留下一个反映我的代码现实的示例。它包含一些注释，以使其更易于理解。

实施日常检查新帖子的例程的最佳方法是什么？ 记住：

用户可以随时输入新帖子。
该机器人可以同时管理成百上千个帐户。必须消耗尽可能少的处理。


    package main

    import (
        "fmt"
        "sync"
        "time"
    )

    var botRunning = true
    var wg = &sync.WaitGroup{}

    func main() {
        // I start the routine of checking for and posting scheduled appointments.
        wg.Add(1)
        go postingScheduled()

        // Later the user passes the command to stop the post.
        // At that moment I would like to stop the routine immediately without getting stuck in a loop.
        // What is the best way to do this?
        time.Sleep(3 * time.Second)
        botRunning = false

        // ignore down
        time.Sleep(2 * time.Second)
        panic("")

        wg.Wait()
    }

    // Function that keeps checking whether the routine should continue or not.
    // Check every 2 seconds.
    // I think this is very wrong because it consumes unnecessary resources.
    // -> Is there another way to do this?
    func checkRunning() {
        for {
            fmt.Println("Pause/Running? - ", botRunning)
            if botRunning {
                break
            }
            time.Sleep(2 * time.Second)
        }
    }

    // Routine that looks for the scheduled posts in the database.
    // It inserts the date of the posts in the Ticker and when the time comes the posting takes place.
    // This application will have hundreds of social network accounts and each will have its own function running in parallel.
    // -> What better way to check constantly if there are scheduled items in the database consuming the least resources on the machine?
    // -> Another important question. User can schedule posts to the database at any time. How do I check for new posts schedule while the Ticker is waiting for the time the last posting loaded?
    func postingScheduled() {
        fmt.Println("Init bot posting routine")
        defer wg.Done()
        for {
            checkRunning()
            <-time.NewTicker(2 * time.Second).C
            fmt.Println("posted success")
        }

    }

在彼得的回应下，我能够适应所有需要以组装草图。

我不知道这是否是最好的方法，也许某些功能会不必要地消耗处理资源。如果有人对重构有更好的想法，我将不胜感激。

有什么更好的方法来实现在社交网络中验证和执行帖子的例程？
