HarmonyOS 调用access.enableBluetooth()申请打开蓝牙，用户点击拒绝，如何捕获用户操作状态？

可以通过access.getState或者access.on(‘stateChange’)获取蓝牙开关状态。

参考demo(查看下代码里面是否获取了蓝牙权限):

import { util } from '@kit.ArkTS';
import { BusinessError } from '@ohos.base';
import { access } from '@kit.ConnectivityKit';
import { abilityAccessCtrl, PermissionRequestResult } from '@kit.AbilityKit';


@Entry
@Component
struct Index {
  @State message: string = '获取蓝牙权限';

  requestPermissionsFromUser() {
    let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
    try {
      let context = getContext(this);
      atManager.requestPermissionsFromUser(context, ['ohos.permission.ACCESS_BLUETOOTH'], (err: BusinessError, data: PermissionRequestResult) => {
        console.info('data:' + JSON.stringify(data));
        console.info('data permissions:' + data.permissions);
        console.info('data authResults:' + data.authResults);
      });
    } catch (err) {
      console.log(`catch err->${JSON.stringify(err)}`);
    }
  }

  build() {
    Column() {
      Text(this.message)
        .id('HelloWorld')
        .fontSize(50)
        .fontWeight(FontWeight.Bold)
        .onClick(()=>{
          this.requestPermissionsFromUser()
        })
      Text('开启蓝牙').onClick(()=>{
        try {
          access.enableBluetooth();
        } catch (err) {
          console.error('errCode: ' + (err as BusinessError).code + ', errMessage: ' + (err as BusinessError).message);
        }

      })
      Text('xxxx')
      Text('开关状态').onClick(()=>{
        try {
          let state = access.getState();
          console.log('blestate:'+state)
        } catch (err) {
          console.error('errCode: ' + (err as BusinessError).code + ', errMessage: ' + (err as BusinessError).message);
        }
      })
    }
    .height('100%')
    .width('100%')
  }
}
