1# 程序访问子系统变更说明
2## cl.access_token.1 requestPermissionsFromUser申请位置权限时行为变更
3
4**访问级别**
5
6公开接口
7
8**变更原因**
9
10该变更为非兼容性变更。根据安全隐私要求，位置权限申请使用时，申请精确/后台位置权限，要同时申请模糊权限。
11
12**变更影响**
13
14变更前，通过调用[requestPermissionsFromUser](../../../application-dev/reference/apis/js-apis-abilityAccessCtrl.md#requestpermissionsfromuser9)接口申请位置权限，如下两种申请情况都可以顺利拉起弹窗：
15
161、在未申请模糊权限[ohos.permission.APPROXIMATELY_LOCATION](../../../application-dev/security/permission-list.md#ohospermissionapproximately_location)的情况下，请求后台位置权限[ohos.permission.LOCATION_IN_BACKGROUND](../../../application-dev/security/permission-list.md#ohospermissionlocation_in_background)
17
182、在未申请模糊权限[ohos.permission.APPROXIMATELY_LOCATION](../../../application-dev/security/permission-list.md#ohospermissionapproximately_location)的情况下，同时请求后台位置权限[ohos.permission.LOCATION_IN_BACKGROUND](../../../application-dev/security/permission-list.md#ohospermissionlocation_in_background)及精准权限[ohos.permission.LOCATION](../../../application-dev/security/permission-list.md#ohospermissionlocation)；
19
20变更后，上述两种情况将无法拉起弹窗授予权限。应用在申请精准权限或后台权限时，必须同时申请模糊权限。
21
22**变更发生版本**
23
24从OpenHarmony SDK 4.1.1.5开始。
25
26**变更的接口/组件**
27
28@ohos.abilityAccessCtrl.d.ts中requestPermissionsFromUser接口，使用该接口申请位置权限的应用，在申请精准权限或后台权限时，必须同时申请模糊权限。

111**适配指导**
112
113修改EntryAbility.ets和导入GlobalThis等步骤参考[requestPermissionsFromUser](../../../application-dev/reference/apis/js-apis-abilityAccessCtrl.md#requestpermissionsfromuser9)
114
115```ts
116    let context: common.UIAbilityContext = GlobalThis.getInstance().getContext('context');
117    atManager.requestPermissionsFromUser(context, ['ohos.permission.APPROXIMATELY_LOCATION', 'ohos.permission.LOCATION', 'ohos.permission.LOCATION_IN_BACKGROUND']).then((data) => {
118        console.info('data:' + JSON.stringify(data));
119    }).catch((err: BusinessError) => {
120        console.info('data:' + JSON.stringify(err));
121    })
122```
