在Go语言中如何解决并发消息广播问题？

type Message struct {
    Content string
}

var messageChannel = make(chan Message)

func broadcastMessage() {
    for {
        // 从消息通道中读取消息
        msg := <-messageChannel
        
        // 遍历所有接收者
        for _, receiver := range receivers {
            // 将消息发送给接收者
            receiver <- msg
        }
    }
}

func proceSSMessage(receiver chan Message) {
    for {
        // 从接收者通道中读取消息
        msg := <-receiver
        
        // 处理消息
        fmt.Println("Received message:", msg.Content)
    }
}

var receivers = make([]chan Message, 0)

func main() {
    // 创建10个接收者通道
    for i := 0; i < 10; i++ {
        receiver := make(chan Message)
        receivers = append(receivers, receiver)
        
        // 启动消息处理协程
        go processMessage(receiver)
    }
    
    // 启动消息广播协程
    go broadcastMessage()

    // 发送消息
    messageChannel <- Message{Content: "Hello World!"}

    // 程序继续运行
    select {}
}
