[Golang系列] GOFLY在线客服系统-gin框架升级http连接为websocket-GO语言实现开源独立部署客服系统

gin框架实现websocket服务非常简单，只需要升级一下http请求，就可以实现了

比如下面的控制器部分代码

//包级变量,升级器
var upgrader = websocket.Upgrader{}

func init() {
    //初始化
    upgrader = websocket.Upgrader{
        ReadBufferSize:  1024,
        WriteBufferSize: 1024,
        // 解决跨域问题
        CheckOrigin: func(r *http.Request) bool {
            return true
        },
    }
}

func VisitorWebsocketServer(c *gin.Context) {
    conn, err := upgrader.Upgrade(c.Writer, c.Request, nil)
    if err != nil {
        log.Println("upgrade error:", err)
        return
    }
    for {
        //接受消息
        var receive []byte
        messageType, receive, err := conn.ReadMessage()
        if err != nil {
            log.Println(err)
            return
        }
        log.Println(string(receive), messageType)
    }
}

增加api路由

    wsGroup := engine.Group("/ws")
    {
        wsGroup.GET("/v2/visitor", middleware.Ipblack, wsV2.VisitorWebsocketServer)
    }

前端连接访问就可以了

ws://xxxxxxxx/ws/v2/visitor
