## uri命名规则
标准uri定义结构如下:
**Scheme://authority/path**
- Scheme: 协议名,对于data share统一为datashare
- authority: [userinfo@]host[:port]
- userinfo: 登录信息,不需要填写。
- host: 服务器地址,如果跨设备访问则为目标设备的ID,如果为本设备则为空。
- port: 服务器端口,不需要填写。
- path: data share的标识信息和资源的路径信息,需要包含data share的标识信息,资源的路径信息可以不填写。
uri示例:
- 不包含资源路径: `datashare:///com.samples.datasharetest.DataShare`
- 包含资源路径: `datashare:///com.samples.datasharetest.DataShare/DB00/TBL00`
其中,data share的标识信息为`com.samples.datasharetest.DataShare`,资源路径为`DB00/TBL00`
