使用golang设计一个key是playerid,value是channel的map。当写入数据的时候,如果playerid对应的channel不存在,那么创建一个channel,并将数据写入channel ; 定时检查当channel为空的时候,10s后删除该值,并且该map可以并发使用。

Golang 看看
好的,这是一个关于使用golang设计一个key是playerid,value是channel的map的问题。可以使用sync包中的Mutex来实现并发使用,使用time包中的Ticker来定时检查channel是否为空并删除。具体实现可以参考以下代码:
```go
package main
import (
"sync"
"time"
)
type Player struct {
channel chan interface{}
mutex sync.Mutex
}
type PlayerMap struct {
players map[string]*Player
mutex sync.Mutex
}
func NewPlayerMap() *PlayerMap {
return &PlayerMap{
players: make(map[string]*Player),
}
}
func (pm *PlayerMap) Write(playerID string, data interface{}) {
pm.mutex.Lock()
defer pm.mutex.Unlock()
player, ok := pm.players[playerID]
if !ok {
player = &Player{
channel: make(chan interface{}),
}
pm.players[playerID] = player
}
player.mutex.Lock()
defer player.mutex.Unlock()
player.channel <- data
}
func (pm *PlayerMap) StartCleaner() {
ticker := time.NewTicker(10 * time.Second)
defer ticker.Stop()
for range ticker.C {
pm.mutex.Lock()
for playerID, player := range pm.players {
player.mutex.Lock()
select {
case <-player.channel:
// Channel not empty, do nothing
default:
// Channel empty, delete player
delete(pm.players, playerID)
}
player.mutex.Unlock()
}
pm.mutex.Unlock()
}
}
```
使用示例:
```go
func main() {
pm := NewPlayerMap()
// Start cleaner
go pm.StartCleaner()
// Write data
pm.Write("player1", "data1")
pm.Write("player2", "data2")
// Wait for data to be processed
time.Sleep(1 * time.Second)
}
```
