Rexsee API介绍：SMS短信读取

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。
