一、效果预览
| 编号 | 功能说明 | 效果图 |
|---|---|---|
通用型 | 该模板集成了文字聊天、表情包聊天、发送图片、发送红包、发送文件一系列功能 |  |
模板型 | 该模板是基于客户服务类型的聊天形式所设计，其用途在于第一时间快速回复用户信息 |  |
简单型 | 该模板提供了最为简单、明了的聊天模式，样式清新，方便在其基础上进行自定义开发 |  |
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
融云SDK–IM通信小程序版
