    在进行权限申请之前，需要先检查当前应用程序是否已经被授予了权限。可以通过调用[checkAccessToken()](../reference/apis/js-apis-abilityAccessCtrl.md#checkaccesstoken9)方法来校验当前是否已经授权。如果已经授权，则可以直接访问目标操作，否则需要进行下一步操作，即向用户申请授权。

+   ArkTS语法不支持直接使用globalThis，需要通过一个单例的map来做中转。开发者需要：
+
+   a. 在EntryAbility.ets中导入构建的单例对象GlobalThis。
+      ```typescript
+       import { GlobalThis } from '../utils/globalThis'; // 需要根据globalThis.ets的路径自行适配
+      ```
+   b. 在onCreate中添加:
+      ```typescript
+       GlobalThis.getInstance().setContext('context', this.context);
+      ```

+   > **说明：**
+   >
+   > 由于在ts中引入ets文件会有告警提示，需要将EntryAbility.ts的文件后缀修改为EntryAbility.ets，并在module.json5中同步修改。
