我正在编写一个小型应用程序来在社交网络上执行自动发布。
我的意图是用户可以通过网络界面在特定时间创建帖子，机器人可以检查安排的新帖子并执行它们。
我在 Go 上处理例程和频道时遇到问题。
我将在下面留下一个反映我的代码实际情况的示例。它包含一些注释以使其更易于理解。
实施随时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数百/数千个帐户。尽可能少地消耗处理是必不可少的。
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")
}
}
