Question

调用媒体库getAlbums方法，需要申请什么权限

Answer 1

步骤 1

在module.json5中配置权限：

"requestPermissions": [ 
  { 
    "name": "ohos.permission.READ_MEDIA" 
  } 
]

步骤 2
在EntryAbility.ts -> onWindowStageCreate页面加载前需要增加用户授权代码：

import abilityAccessCtrl, { Context, PermissionRequestResult } from '@ohos.abilityAccessCtrl'; 
import { BusinessError } from '@ohos.base'; 
 
let permissionList: Array<string> = [ 
  "ohos.permission.READ_MEDIA" 
]; 
this.context.requestPermissionsFromUser(permissionList) 
  .then((data: PermissionRequestResult) => { 
    console.info(`request permission data result = ${data.authResults}`); 
  }) 
  .catch((err: BusinessError) => { 
    console.error(`fail to request permission error:${err}`); 
  })
