**Example**

For details about how to obtain the context in the example, see [Obtaining the Context of UIAbility](../../application-models/uiability-usage.md#obtaining-the-context-of-uiability).

```ts
import abilityAccessCtrl from '@ohos.abilityAccessCtrl';
import { BusinessError } from '@ohos.base';
import common from '@ohos.app.ability.common';

let atManager = abilityAccessCtrl.createAtManager();
try {
  let context: Context = this.getUIContext().getHostContext() as common.UIAbilityContext;
  atManager.requestPermissionsFromUser(context, ["ohos.permission.CAMERA"]).then((data) => {
      console.info("data:" + JSON.stringify(data));
      console.info("data permissions:" + data.permissions);
      console.info("data authResults:" + data.authResults);
      console.info("data dialogShownResults:" + data.dialogShownResults);
      console.info("data errorReasons:" + data.errorReasons);
  }).catch((err: BusinessError) => {
      console.error("data:" + JSON.stringify(err));
  })
} catch(err) {
  console.error(`catch err->${JSON.stringify(err)}`);
}
