鸿蒙开发请求位置，获取位置信息

查询是否已授权，再获取位置

import { geoLocationManager } from '@kit.LocationKit';
import { BusinessError } from '@kit.BasicServicesKit';
import abilityAccessCtrl, { PermissionRequestResult } from '@ohos.abilityAccessCtrl';
import { bundleManager, common } from '@kit.AbilityKit';

获取AccessToken

可以去程序服务控制管理去查询

  getTokenID(){
    let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_APPLICATION | bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_METADATA;
    try {
      bundleManager.getBundleInfoForSelf(bundleFlags).then((data) => {
        const bundleInfo = data
        this.accessTokenId = bundleInfo.appInfo.accessTokenId;
        this.checkAccessToken()
      }).catch((err: BusinessError) => {
        console.error('getBundleInfoForSelf error',JSON.stringify(err))
      });
    } catch (err) {
      console.error('fail error')
    }
  }

查询是否已授权

  checkAccessToken(){
    let atManager = abilityAccessCtrl.createAtManager();
    try {
      atManager.checkAccessToken(this.accessTokenId, "ohos.permission.APPROXIMATELY_LOCATION").then((data) => {
        console.log('checkAccessToken success',data);
        // -1 未授权，0 已授权
       if(data === 0){
         this.getCurrentLocation()
       }else {
         this.requestPermissionsFromUser()
       }
      }).catch((err:ESObject) => {
        console.log('checkAccessToken success',JSON.stringify(err));
      });
    } catch(err) {
      console.log(`catch err->${JSON.stringify(err)}`);
    }
  }

未授权

拉起弹窗（这个需要去AGC官网项目应用那里配置）

  requestPermissionsFromUser(){
  let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
  let context: Context = getContext(this) as common.UIAbilityContext;
  atManager.requestPermissionsFromUser(context, ['ohos.permission.APPROXIMATELY_LOCATION']).then((data: PermissionRequestResult) => {
  console.info('requestPermissionsFromUser:' + JSON.stringify(data));
}).catch((err: BusinessError) => {
  console.error('requestPermissionsFromUser:' + JSON.stringify(err));
});
}

已授权

  getCurrentLocation(){
    geoLocationManager.getCurrentLocation().then((result) => {
      console.log('current location latitude: ' , JSON.stringify(result));
    }).catch((err: BusinessError ) => {
      console.error(`getCurrentLocation failed. Code: ${err.code}, message: ${err.message}`);
    });
  }
