位置服务
1、首先申请权限
在module.json5文件下申请位置权限
"requestPermissions": [{"name": "ohos.permission.LOCATION", // 权限名称，为系统已定义的权限"reason": "$string:location_reason", // 申请权限的原因，当申请权限为user_grant权限时该字段为必填"usedScene": { // 用于描述权限使用场景，当申请权限为user_grant权限时该字段为必填"abilities": ["EntryAbility"],"when": "always" // 调用时机（inuse：使用时；always：始终）}},{"name": "ohos.permission.APPROXIMATELY_LOCATION","reason": "$string:location_reason","usedScene": {"abilities": ["EntryAbility"],"when": "always"}}]
$string:location_reason
会爆红，就需要在
文件下定义一下，
2、导入需要的包
import { abilityAccessCtrl, common, Permissions } from '@kit.AbilityKit';
import { BusinessError } from '@kit.BasicServicesKit';
import { geoLocationManager } from '@kit.LocationKit';
3、看一下用户是否授权，没有授权拉起弹窗让用户授权
const permissions: Array<Permissions> = ['ohos.permission.LOCATION'];
// 使用UIExtensionAbility：将common.UIAbilityContext 替换为common.UIExtensionContext
export function reqPermissionsFromUser(permissions: Array<Permissions>, context: common.UIAbilityContext): void {let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();// requestPermissionsFromUser会判断权限的授权状态来决定是否唤起弹窗atManager.requestPermissionsFromUser(context, permissions).then((data) => {let grantStatus
