来源：互联网发布：windows wep 索引编辑：程序博客网时间：2024/05/21 07:56

一、Bmob简介

（1）数据服务
支持丰富的数据类型，灵活方便的增删改查，可视化的数据操作，安全的角色和ACL管理，多表关联处理，数据的批量处理，本地数据缓存，开发者们无需关注服务器后端，就可以实现多平台的同步开发。
（2）文件服务
文件服务允许上传任何的文件类型，支持分片断点续传，此外，针对移动端对图片业务的需求，还提供了生成高压缩比的缩略图服务。
（3）推送服务
提供了Android和iOS两个版本的推送服务，采用Websocket保持长连接，稳定性更好，目前，64GB的单机能够支撑600万的用户长连接。
（4）扩展服务
提供APP官网、计划任务、地理位置、云端代码等扩展服务，确保您的个性化业务逻辑能够在云端更好的运转。
