HBuilder+HTML5 Plus+MUI实现拍照或者相册选择图片上传，利用HTML5 Plus的Camera、Gallery、IO、Storage和Uploader来实现手机APP拍照或者从相册选择图片上传。Camera模块管理设备的摄像头，可用于拍照、摄像操作，通过plus.camera获取摄像头管理对象。Gallery模块管理系统相册，支持从相册中选择图片或视频文件、保存图片或视频文件到相册等功能。通过plus.gallery获取相册管理对象。IO模块管理本地文件系统，用于对文件系统的目录浏览、文件的读取、文件的写入等操作。通过plus.io可获取文件系统管理对象。Storage模块管理应用本地数据存储区，用于应用数据的保存和读取。应用本地数据与localStorage、sessionStorage的区别在于数据有效域不同，前者可在应用内跨域操作，数据存储期是持久化的，并且没有容量限制。通过plus.storage可获取应用本地数据管理对象。Uploader模块管理网络上传任务，用于从本地上传各种文件到服务器，并支持跨域访问操作。通过plus.uploader可获取上传管理对象。Uploader上传使用HTTP的POST方式提交数据，数据格式符合Multipart/form-data规范，即rfc1867（Form-based File Upload in HTML）协议。
