harmonyOS开发技巧（一）——封装hilog日志

1. 创建sharedLibrary共享hsp包commonLib：功能工具类。

import hilog from '@ohos.hilog';class Logger {private DOMAIN: number = 0x0000;private APP_NAME: string = 'Myapplication';public info(tag: string, ...args: string[]) {hilog.info(this.DOMAIN, `[${this.APP_NAME}.${tag}]`, '%{public}s', args.join(''));}public error(tag: string, ...args: string[]) {hilog.error(this.DOMAIN, `[${this.APP_NAME}.${tag}]`, '%{public}s', args.join(''));}
}export const logger = new Logger();

• commonLib导出logger类：

export { logger } from "./utils/Logger";

• 其他模块引入commonLib：

 "devDependencies": {"@ohos/commonLib": "file:./commonLib"}

• 其他模块使用logger：

import { logger } from '@ohos/commonLib';
logger.info(TAG, 'Ability onCreate');
