1# 基础通信子系统WiFi ChangeLog 2 3## cl.location.1 位置服务权限变更 4 5从API9开始，增加ohos.permission.APPROXIMATELY_LOCATION，表示模糊位置权限。 6 7如果应用开发者使用的API版本大于等于9，则需要同时申请ohos.permission.LOCATION和ohos.permission.APPROXIMATELY_LOCATION，单独申请ohos.permission.LOCATION会失败。 8 9**变更影响** 10 11如果是存量应用（使用的API版本小于9），则无影响。如果使用的API版本大于等于9，位置服务权限申请方式有变更，详情如下： 12 13应用在使用系统能力前，需要检查是否已经获取用户授权访问设备位置信息。如未获得授权，可以向用户申请需要的位置权限，申请方式请参考下文。 14 15系统提供的定位权限有： 16 17- ohos.permission.LOCATION 18 19- ohos.permission.APPROXIMATELY_LOCATION 20 21- ohos.permission.LOCATION_IN_BACKGROUND 22 23访问设备的位置信息，必须申请权限，并且获得用户授权。 24 25API9之前的版本，申请ohos.permission.LOCATION即可。 26 27API9及之后的版本，需要申请ohos.permission.APPROXIMATELY_LOCATION或者同时申请ohos.permission.APPROXIMATELY_LOCATION和ohos.permission.LOCATION；无法单独申请ohos.permission.LOCATION。 28 29| 使用的API版本 | 申请位置权限 | 申请结果 | 位置的精确度 | 30| -------- | -------- | -------- | -------- | 31| 小于9 | ohos.permission.LOCATION | 成功 | 获取到精准位置，精准度在米级别。 | 32| 大于等于9 | ohos.permission.LOCATION | 失败 | 无法获取位置。 | 33| 大于等于9 | ohos.permission.APPROXIMATELY_LOCATION | 成功 | 获取到模糊位置，精确度为5公里。 | 34| 大于等于9 | ohos.permission.APPROXIMATELY_LOCATION和ohos.permission.LOCATION | 成功 | 获取到精准位置，精准度在米级别。 | 35 36如果应用在后台运行时也需要访问设备位置，除需要将应用声明为允许后台运行外，还必须申请ohos.permission.LOCATION_IN_BACKGROUND权限，这样应用在切入后台之后，系统可以继续上报位置信息。 37 38开发者可以在应用配置文件中声明所需要的权限，具体可参考[授权申请指导](../../../application-dev/security/accesstoken-guidelines.md)。 39 40**关键的接口/组件变更** 41 42| 类名 | 接口类型 | 接口声明 | 变更类型 | 43| -- | -- | -- | -- | 44|wifiManager| method | function scan(): void;
