2、人脸识别demo如下：

import { common, Want } from '@kit.AbilityKit';

@Entry
@Component
struct Index {
  private context = getContext(this) as common.UIAbilityContext

  build() {
    Column() {
      Button('跳转到设置')
        .onClick(() => {
          let want: Want = {
            bundleName: 'com.huawei.hmos.settings',
            abilityName: 'com.huawei.hmos.settings.MainAbility',
            uri: 'biometrics_and_password_settings',
            parameters: {
              pushParams: "com.example.jump2setting"
            }
          };
          this.context.startAbility(want)
        })
    }
    .width("100%")
    .height("100%")
    .alignItems(HorizontalAlign.Center)
    .justifyContent(FlexAlign.Center)
  }
}
