 通过atManager实例来获取。
 
 **示例：**
+
+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。
+
+**globalThis.ets示例代码如下：**
+```typescript
+import common from '@ohos.app.ability.common';
+
+// 构造单例对象
+export class GlobalThis {
+  private constructor() {}
+  private static instance: GlobalThis;
+  private _uiContexts = new Map<string, common.UIAbilityContext>();
+
+  public static getInstance(): GlobalThis {
+    if (!GlobalThis.instance) {
+      GlobalThis.instance = new GlobalThis();
+    }
+    return GlobalThis.instance;
+  }
+
+  getContext(key: string): common.UIAbilityContext | undefined {
+    return this._uiContexts.get(key);
+  }
+
+  setContext(key: string, value: common.UIAbilityContext): void {
+    this._uiContexts.set(key, value);
+  }
+
+  // 其他需要传递的内容依此扩展
+}
+```
+
 ```ts
+import { BusinessError } from '@ohos.base';
 import abilityAccessCtrl from '@ohos.abilityAccessCtrl';
+import common from '@ohos.app.ability.common';
+import { GlobalThis } from '../utils/globalThis';
+
 let atManager = abilityAccessCtrl.createAtManager();
 try {
-  atManager.requestPermissionsFromUser(this.context, ["ohos.permission.CAMERA"]).then((data) => {

       console.info("data:" + JSON.stringify(data));
       console.info("data permissions:" + data.permissions);
