Rexsee API介绍：SMS短信读取
Rexsee是一个开源的移动Web开发平台，深度支持Android。目前已扩展了接近2000个API，可以通过js直接实现Android原生功能。陆续梳理相关的对象与事件说明，并将源码贴出来。有兴趣的TX也可以在Rexsee的社区直接查看详细内容：http://www.rexsee.com/CN/helpReference.php
基于rexsee扩展的rexseeSMS，通过JS实现短信读取相关功能，如：
【函数】 JsonArray getContentUris()
【说明】 读取短信相关的所有数据库表的Uri地址。
【返回】 Json对象字符串，可以用eval('('+json+')')转换为JavaScript对象。
【参数】 无
【示例】
alert(rexseeSMS.getContentUris());
【函数】 JsonObjectArray get(int number)
【说明】 读取若干条短信。
【返回】 Json对象数组字符串，可以用eval('('+json+')')转换为JavaScript对象数组，注意，其中body字段是escape过的，使用前需要unescape。
【参数】 number：要读取的短信条数。
【示例】
alert(rexseeSMS.get(10));
alert(unescape(eval('('+rexseeSMS.get(1)+')')[0].body));
其它还有：
- getUnread(int number)：读取若干条未读短信；
- getRead(int number)：读取若干条已读短信；
- getInbox(int number)：从收件箱读取若干条短信；
- getSent(int number)：读取若干条已发短信；
- getByThread(int threadID)：读取会话中所有短信；
- getThreads(int number)：读取若干条会话；
- getData(String selection, int number)：根据条件读取若干条短信。
