import { deviceInfo } from '@kit.BasicServicesKit';
import { intl } from '@kit.LocalizationKit';/*** 获取手机信息*/
export default class PhoneUtils {private static instance: PhoneUtils = new PhoneUtils();private versionCode: string = ""private versionName: string = ""private constructor() {let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_DEFAULTconst data:bundleManager.BundleInfo = bundleManager.getBundleInfoForSelfSync(bundleFlags)this.versionCode = data.versionCode.toString()this.versionName = data.versionName.toString()}public static getInstance(): PhoneUtils {return PhoneUtils.instance}/*** 獲取 Code* @returns*/getAppCode(): string {return this.versionCode}/*** 获取 Version* @returns*/getVersionName(): string {return this.versionName}/*** 手機版本*/getPhoneVersion(): string {return deviceInfo.osFullName}/*** 获取系统语言*/getPhoneLanguage(): string {let locale = new intl.Locale();return locale.language}
