-# uriPermissionManager
-
-uriPermissionManager模块提供了Uri权限管理的能力。
-
-> **说明：**
-> 
-> 本模块首批接口从API version 9 开始支持。后续版本的新增接口，采用上角标单独标记接口的起始版本。
-
-## 导入模块
-  
-```
-import UriPermissionManager from '@ohos.application.uriPermissionManager';
-```
-
-## uriPermissionManager.verifyUriPermission
-
-verifyUriPermission(uri: string, flag: wantConstant.Flags, accessTokenId: number, callback: AsyncCallback&lt;number&gt;): void
-
-检验某个应用是否对指定的uri有flag指定的权限。
-
-**系统能力:**
-
-SystemCapability.Ability.AbilityRuntime.Core
-
-**参数：**
-
-  | 参数名 | 类型 | 必填 | 说明 | 
-  | -------- | -------- | -------- | -------- |
-  | uri | string | 是 | 指向文件的uri，例如fileshare:///com.samples.filesharetest.FileShare/person/10。 | 
-  | flag | wantConstant.Flags | 是 | uri的读权限或写权限。 | 
-  | accessTokenId | number | 是 | 每个应用的唯一标识ID，开发者通过包管理接口自行获取。 | 
-  | callback | AsyncCallback&lt;number&gt; | 是 | callback形式返回检验结果，返回0表示有权限，返回-1表示无权限。 | 
-
-**示例：**
-    
-  ```js
-  import WantConstant from '@ohos.ability.wantConstant';
-  let accessTokenId =1
-  let uri = "fileshare:///com.samples.filesharetest.FileShare/person/10"
-  UriPermissionManager.verifyUriPermission(uri, WantConstant.Flags.FLAG_AUTH_READ_URI_PERMISSION, accessTokenId, (result) => {
-      console.log("result.code = " + result.code)
-  }) // accessTokenId开发者通过包管理接口自行获取
