rongCloud2 3.2.8 版本更新后添加了发送小视频接口，发送文件接口。
rongCloud2 概述
融云是国内首家专业的即时通讯云服务提供商，专注为互联网、移动互联网开发者提供即时通讯基础能力和云端服务。通过融云平台，开发者不必搭建服务端硬件环境，就可以将即时通讯、实时网络能力快速集成至应用中。
rongCloud2 封装了融云即时通讯能力库 IMLib SDK 的 API，对融云的相关接口做了一一对应的封装，功能详情可参考目录。
使用 rongCloud2 模块之前，请先 注册 融云的开发者帐号并申请创建 App，创建 App 后，可以在 开发者后台 获取 App Key 和 App Secret 用于开发。开发前请先认真阅读相关的 融云开发文档和视频。（请在PC端打开）
由于 （android ）融云sdk 不支持中文路径，需要处理一下，用fs 模块 调用rename接口重命名一下，为了不影响原文件需要先复制一下再进行处理。方法不唯一，提供参考
所用 模块 rongcloud2、fs 模块、fileBrowser 模块以下是页面源码 包括简易登陆获取token页面主功能页面。
