HarmonyOS 采用Capi方式运行AVScreenCapture功能异常

采用Capi调用运行OH_AVScreenCapture_StartScreenCapture执行屏幕采集操作，通过OH_AVScreenCapture_SetErrorCallback设置的回调被触发返回：OH_AVErrCode=6，提示未知异常。

该问题原因是配置中增加了OH_MIC枚举但是没有显示的声明权限导致。

// 权限申请参考如下，这边在界面到前台时申请
import { hilog } from '@kit.PerformanceAnalysisKit';
import testNapi from 'libentry.so';
import { abilityAccessCtrl, common, Permissions } from '@kit.AbilityKit';
import { BusinessError } from '@kit.BasicServicesKit';

const permissions: Array<Permissions> = ['ohos.permission.MICROPHONE'];

function reqPermissionsFromUser(permissions: Array<Permissions>, context: common.Context): 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: Array<number> = data.authResults;
    let length: number = grantStatus.length;
    for (let i = 0; i < length; i++) {
      if (grantStatus[i] === 0) {
        // 用户授权，可以继续访问目标操作
      } else {
        // 用户拒绝授权，提示用户必须授权才能访问当前页面的功能，并引导用户到系统设置中打开相应的权限
        return;
      }
    }
    // 授权成功
  }).catch((err: BusinessError) => {
    console.error(`Failed to request permissions from user. Code is ${err.code}, message is ${err.message}`);
  })
}

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';
  testTag: string = "wangz::";
  aboutToAppear(): void {
    reqPermissionsFromUser(permissions, getContext());
  }

  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(() => {
            hilog.info(0x0000, this.testTag, 'Test NAPI 2 + 3 = %{public}d', testNapi.add(2, 3));
            hilog.info(0x0000, this.testTag, 'screenTest::' + testNapi.screenTest());
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}
