RESTful Android

RESTful Android API 定义

约定

• 回复中默认包含标头： Content-Type: application/json;charset=UTF-8

• 异步操作以（*）号标记

• 大多数异步操作同时只能有一个任务在进行，以上传联系人为例：

  1. 客户端每次提交 POST /persons/uploader服务器放弃进行中的上传任务而新建；

  2. 客户端可以先访问GET /persons/uploader 获得当前是否有正在上传的任务；

  3. 服务器遇到错误的时候会将任务挂起，返回错误原因，客户端可以选择重试或者终止；

  4. 客户端接收到任务失败的响应后，如果响应中不包括retry的链接，则不应该重试；

• 授权失败将返回403 Forbidden，客户端应该提示用户进行授权，同时进行重试。
