二、配套SDK推荐
对于实时聊天业务,其中最重要的功能是实现多人聊天之间的信息实时同步。那么问题来了,实现消息同步的方式有很多:
- 你可以自己手写一个通信服务器,用socket通信配合像
netty
这样的多线程容器。 - 你也可以借助更多第三方的消息中间件,像
kafka
或者zookeeper
这样的消息订阅通知的模型去做。 - 我们也能从前端的角度出发,充分利用
websockt
协议这样的长连接通信协议。
往往要开发一个功能完备、效率稳定的通信服务功能都不是那么简单易行的。所以,我们在开发小程序或者APP时,我们追求的是快准狠!这个时候我们选择合适且靠谱的第三方SDK就显得尤为重要!以下就是个人推荐的好用的第三方IM SDK:
2.1 Go-Easy SDK
- Go-Easy SDK地址 : 小程序开发的首选,有丰富的示例接入,兼容web端。可以实现更低的接入学习成本,达到更好的效果!
GoEasy致力于打造"Web开发人员最喜爱的即时通讯平台", 只需要一个SDK,就可以帮助开发人员快速的完成各种即时通讯功能:
- 提醒类: 系统提醒,订单提醒等
- 数据实时更新:页面同步,位置实时跟踪,实时图表
- 直播间聊天室
- 用户在线状态监听
- 手机APP通知栏推送
- 游戏对战
- IM聊天
2.2 腾讯云 IM SDK
腾讯云IM SDK地址:按照官方文档对小程序端的IM即时通信进行集成!
2.3 声网SDK
声网-适配于小程序端的SDK地址 : 声网作为一个以RTC技术发家的企业,其在通信业务的能力上有很强的技术储备,所以他在音视频领域的能力也同样值得借鉴。
2.3 融云SDK
