system_grant 为系统授权无需询问用户常用的权限包括网络请求、获取网络信息、获取wifi信息、获取传感器数据等。
/* system_grant系统授权*/static readonly INTERNET ohos.permission.INTERNET // 网路请求static readonly GET_NETWORK_INFO ohos.permission.GET_NETWORK_INFO // 网络信息-读static readonly GET_WIFI_INFO ohos.permission.GET_WIFI_INFO // WIFI信息-读static readonly GYROSCOPE ohos.permission.GYROSCOPE // 陀螺仪传感器static readonly ACCELEROMETER ohos.permission.ACCELEROMETER // 加速度传感器
2. user_grant
user_grant 是需要用户授权的权限常用的权限包括定位、相机、麦克风、日历、文件读写等。
/* user_grant用户授权*/static readonly LOCATION ohos.permission.LOCATION // 定位-精确static readonly APPROXIMATELY_LOCATION ohos.permission.APPROXIMATELY_LOCATION // 定位-模糊static readonly LOCATION_IN_BACKGROUND ohos.permission.LOCATION_IN_BACKGROUND // 定位-后台static readonly CAMERA ohos.permission.CAMERA // 相机static readonly MICROPHONE ohos.permission.MICROPHONE // 麦克风static readonly READ_CONTACTS ohos.permission.READ_CONTACTS // 通讯录-读static readonly WRITE_CONTACTS ohos.permission.WRITE_CONTACTS // 通讯录-写static readonly READ_CALENDAR ohos.permission.READ_CALENDAR // 日历-读static readonly WRITE_CALENDAR ohos.permission.WRITE_CALENDAR // 日历-写static readonly WRITE_IMAGEVIDEO ohos.permission.WRITE_IMAGEVIDEO // 图片视频-写static readonly READ_IMAGEVIDEO ohos.permission.READ_IMAGEVIDEO // 图片视频-读static readonly MEDIA_LOCATION ohos.permission.MEDIA_LOCATION // 多媒体-本地static readonly WRITE_AUDIO ohos.permission.WRITE_AUDIO // 音频-写static readonly READ_AUDIO ohos.permission.READ_AUDIO // 音频-读static readonly READ_MEDIA ohos.permission.READ_MEDIA // 文件-读static readonly WRITE_MEDIA ohos.permission.WRITE_MEDIA // 文件-写static readonly APP_TRACKING_CONSENT ohos.permission.APP_TRACKING_CONSENT // 广告标识符static readonly DISTRIBUTED_DATASYNC ohos.permission.DISTRIBUTED_DATASYNC // 多设备协同static readonly ACCESS_BLUETOOTH ohos.permission.ACCESS_BLUETOOTH // 使用蓝牙能力static readonly READ_PASTEBOARD ohos.permission.READ_PASTEBOARD // 剪贴板static readonly READ_HEALTH_DATA ohos.permission.READ_HEALTH_DATA // 健康数据static readonly ACTIVITY_MOTION ohos.permission.ACTIVITY_MOTION // 健身运动
二. 权限声明
1. system_grant
在应用 entry 模块的 module.json5 中添加权限声明。
requestPermissions: [{name: ohos.permission.INTERNET}, {name: ohos.permission.GET_NETWORK_INFO}, {name: ohos.permission.GET_WIFI_INFO}
] 2. user_grant
在应用 entry 模块的 module.json5 中添加权限声明。
requestPermissions: [{name: ohos.permission.LOCATION,reason: $string:PERMISSION_LOCATION,usedScene: {abilities: [EntryAbility],when:inuse}},{name: ohos.permission.APP_TRACKING_CONSENT,reason: $string:PERMISSION_TRACKING_CONSENT,usedScene: {abilities: [EntryAbility],when:inuse}}
]
三. 权限应用
1. system_grant
使用该类权限不需要弹窗让用户授权只需要判断一下该权限在应用中是否声明。
import { abilityAccessCtrl, bundleManager, PermissionRequestResult, Permissions, Want } from kit.AbilityKit;export class PermissionManager {async checkPermissions(): void {const bundleInfo: bundleManager.BundleInfo await bundleManager.getBundleInfoForSelf(bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_APPLICATION)const tokenId bundleInfo.appInfo.accessTokenIdconst atManager abilityAccessCtrl.createAtManager()const state atManager.checkAccessTokenSync(tokenId, ohos.permission.INTERNET)if (state abilityAccessCtrl.GrantStatus.PERMISSION_GRANTED) {console.log(网络请求可用)} else {console.log(网络请求不可用)}}
}
2. user_grant
使用该类权限需要先判断用户是否授权先由用户授权之后再使用该类权限相关的能力。
import { abilityAccessCtrl, bundleManager, PermissionRequestResult, Permissions, common } from kit.AbilityKit;export class PermissionManager {async checkPermissions(): Promisevoid {const bundleInfo: bundleManager.BundleInfo await bundleManager.getBundleInfoForSelf(bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_APPLICATION)const tokenId bundleInfo.appInfo.accessTokenIdconst atManager abilityAccessCtrl.createAtManager()const state atManager.checkAccessTokenSync(tokenId, ohos.permission.LOCATION)if (state abilityAccessCtrl.GrantStatus.PERMISSION_GRANTED) {console.log(定位权限已开启)} else {const context AppStorage.get(ability_context) as common.UIAbilityContext // 在EntryAbility中存储AbilityContextconst result: PermissionRequestResult await atManager.requestPermissionsFromUser(context, [ohos.permission.LOCATION, ohos.permission.APPROXIMATELY_LOCATION])const authResults: Arraynumber result.authResultsconst grantStatus: boolean (authResults[0] 0)if (grantStatus) {console.log(定位权限已开启)} else {console.log(定位权限未开启)} }}
}
3. notification
推送通知的权限是基于 notificationMananger 服务实现不同于 system_agent 和 user_agent。
import notificationManager from ohos.notificationManager;export class PermissionManager {async checkNotificationPermissions(): Promisevoid {let grantStatus await notificationManager.isNotificationEnabled()if (!grantStatus) {await notificationManager.requestEnableNotification()grantStatus await notificationManager.isNotificationEnabled()if (!grantStatus) {console.log(通知权限未开启)} else {console.log(通知权限已开启)}} else {console.log(通知权限已开启)}}
}
4. 跳转到APP设置页
import bundleManager from ohos.bundle.bundleManager;
import { common, Want } from kit.AbilityKit;
import { BusinessError } from kit.BasicServicesKit;export class PermissionManager {async gotoSetting(): Promisevoid {const bundleFlags bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_APPLICATIONconst bundleParam bundleManager.getBundleInfoForSelfSync(bundleFlags)const bundleId bundleParam.namelet wantInfo: Want {bundleName: com.huawei.hmos.settings,abilityName: com.huawei.hmos.settings.MainAbility,uri: application_info_entry,parameters: {pushParams: bundleId}}const context AppStorage.get(ability_context) as common.UIAbilityContext // 在EntryAbility中存储AbilityContextcontext.startAbility(wantInfo).catch((error: BusinessError) {console.error(startAbility-error: ${JSON.stringify(error)})})}
}
