golang用melody搭建轻量的websocket服务的示例代码

package main
import (
	"fmt"
	"net/http"
	"github.com/gin-gonic/gin"
	"github.com/olahol/melody"
)
func main() {
	r := gin.Default()
	// 创建Melody实例
	m := melody.New()
	// 注册WebSocket处理函数
	r.GET("/ws", func(c *gin.Context) {
		err := m.HandleRequest(c.Writer, c.Request)
		if err != nil {
			fmt.Println(err)
		}
	})
	// 处理WebSocket连接
	m.HandleConnect(func(s *melody.Session) {
		fmt.Println("WebSocket connected")
	})
	// 处理WebSocket消息
	m.HandleMessage(func(s *melody.Session, msg []byte) {
		fmt.Println("Received message:", string(msg))
		// 发送消息给所有连接的客户端
		m.Broadcast(msg)
	})
	// 处理WebSocket断开连接
	m.HandleDisconnect(func(s *melody.Session) {
		fmt.Println("WebSocket disconnected")
	})
	// 启动HTTP服务器
	fmt.Println("WebSocket server listening on :8080")
	http.ListenAndServe(":8080", r)
}
