二、项目简介

MobileIMSDK是一套专为移动端开发的原创IM通信层框架:

  • 历经10年、久经考验;
  • 超轻量级、高度提炼,lib包50KB以内;
  • 精心封装,一套API优雅支持UDPTCPWebSocket 三种协议(可能是全网唯一开源的);
  • 客户端支持iOS、Android、标准Java、H5(暂未开源)、小程序(暂未开源)、Uniapp(暂未开源);
  • 服务端基于Netty,性能卓越、易于扩展;:point_left:
  • 可与姊妹工程 MobileIMSDK-Web 无缝互通实现网页端聊天或推送等;:point_left:
  • 可应用于跨设备、跨网络的聊天APP、企业OA、消息推送等各种场景。

MobileIMSDK工程自2013年10月起持续升级至今(当前最新版是v6.5,版本更新日志点此查看 ),历经10年,起初用作某自用产品的即时通讯底层,完全从零开发。
目前,最新Uniapp端已开发完成,希望对需要的人有所启发和帮助。

四、设计目标

让开发者专注于应用逻辑的开发,底层复杂的即时通讯算法交由SDK开发人员,从而解偶即时通讯应用开发的复杂性

五、框架组成

整套MobileIMSDK框架由以下7部分组成:

  1. Android客户端SDK:用于Android版即时通讯客户端,支持Android 4.0及以上,查看API文档
  2. iOS客户端SDK:用于开发iOS版即时通讯客户端,支持iOS 12.0及以上,查看API文档
  3. Java客户端SDK:用于开发跨平台的PC端即时通讯客户端,支持Java 1.6及以上,查看API文档
  4. H5客户端SDK:暂无开源版,查看精编注释版
  5. 微信小程序端SDK:暂无开源版,查看精编注释版
  6. Uniapp端SDK:暂无开源版,查看精编注释版
  7. 服务端SDK:用于开发即时通讯服务端,支持Java 1.7及以上版本,查看API文档

整套MobileIMSDK框架的架构组成:

MobileIMSDK一直在持续开发和升级中,Uniapp客户端 是MobileIMSDK工程的最新成果。

:point_right: 另外:MobileIMSDK可与姊妹工程 MobileIMSDK-Web 无缝互通,从而实现Web网页端聊天或推送等。

六、技术特征

  • 久经考验:历经10年,从Andriod 2.3、iOS 5.0 时代持续升级至今(绝不烂尾);
  • 超轻量级:高度提炼,lib包50KB以内;
  • 多种协议:可能是全网唯一开源可一套API同时支持UDP、TCP、WebSocket三种协议的同类框架 :new:
  • 多种网络:精心优化的TCP、UDP、WebSocket协议实现,可应用于卫星网、移动网、嵌入式物联网等场景;
  • 多端覆盖:客户端支持iOS、Android、标准Java、H5微信小程序Uniap
  • 高效费比:独有的UDP协议实现,无连接特性,同等条件下可实现更高的网络负载和吞吐能力;
  • 消息走向:支持即时通讯技术中消息的所有可能走向,共3种(即C2C、C2S、S2C);
  • 粘包半包:优雅解决各端的TCP经典粘包和半包问题,底层封装,应用层完全无感知;
  • QoS机制:完善的消息送达保证机制(自动重传、消息去重、状态反馈等),不漏过每一条消息;
  • 健壮可靠:实践表明,非常适于在高延迟、跨洲际、不同网络制式环境中稳定、可靠地运行;
  • 断网恢复:拥有网络状况自动检测、断网自动治愈的能力;
  • 原创算法:核心算法和实现均为原创,保证了持续改进和提升的空间;
  • 多种模式:预设多种实时灵敏度模式,可根据不同场景控制即时性、流量和客户端电量消耗;
  • 数据压缩:自有协议实现,未来可自主定制数据压缩,灵活控制客户端的流量、服务端网络吞吐;
  • 高度封装:高度封装的API接口,保证了调用的简易性,也使得可应用于更多的应用场景;
  • Web支持:可与姊妹工程 MobileIMSDK-Web 无缝互通实现网页端聊天或推送等;:point_left:
  • 扩展性好:服务端基于Netty,继承了Netty的优秀高可扩展性;
  • 性能优异:服务端继承了Netty高性能、高吞吐特性,适用于高性能服务端场景。

MobileIMSDK 所支持的全部3种即时通讯消息走向分别是:
(1) Client to Client (C2C):即由某客户端主动发起,接收者是另一客户端;
(2) Client to Server (C2S):即由某客户端主动发起,接收者是服务端;
(3) Server to Client (S2C):即由服务端主动发起,接收者是某客户端。

七、性能测试

压力测试表明,MobileIMSDK用于推送场景时,理论单机负载可接近千万级。用于聊天应用时,单机负载也可达数十万。

当然,每款应用都有各自的特点和差异,请视具体场景具体评估之,测试数据仅供参考。

九、应用案例

① 基于MobileIMSDK的产品级聊天APP:

详细介绍下载体验查看运行截图

② MobileIMSDK在高网络延迟下的案例:

某款基于MobileIMSDK的商业商品,曾运营于跨洲际的复杂网络环境下,端到端通信延迟在洲际网络繁忙时可高达600ms以上(与服务端的单向延迟约为300ms左右,而通常大家访问国内主流门户的延迟约为20~50ms),某段时期的非敏感运营数据 点此查看

十、打包下载(all in one)

十一、典型应用场景

:triangular_flag_on_post: 场景1:聊天APP

  • 应用说明:可用于开发类似于微信、QQ等聊天工具。
  • 消息走向:需使用C2C、C2S、S2C全部类型。
  • 特别说明:MobileIMSDK并未定义聊天应用的应用层逻辑和协议,开发者可自行定义并实现之。

:triangular_flag_on_post: 场景2:消息推送

  • 应用说明:可用于需要向客户端实时推送信息的各种类型APP。
  • 消息走向:仅需使用S2C 1种消息走向,属MobileIMSDK的最简单应用场景。

:triangular_flag_on_post: 场景3:企业OA

  • 应用说明:可用于实现企业OA的指令、公文、申请等各种消息实时推送,极大提升用户体验,并可延伸至移动设备。
  • 消息走向:仅需使用S2C 1种消息走向,属MobileIMSDK的最简单应用场景。

:triangular_flag_on_post: 场景4:企业OA的增强型

  • 应用说明:可用于实现企业OA中各种系统级、用户级消息的实时互动,充分利用即时通讯技术提升传统OA的价值。
  • 消息走向:可使用C2C、C2S、S2C全部类型,这与聊天APP在很多方面已无差别,但企业OA有自已的用户关系管理模型和逻辑,较之全功能聊天APP要简单的多。
