HarmonyOS 退出应用

可以使用UIAbilityContext.terminateSelf退出当前应用，killAllProcesses是找出应用下面所有的进程，逐个kill掉。terminateSelf是走UIAbility的正常生命周期，正常销毁。参考文档：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-inner-application-uiabilitycontext-V5#uiabilitycontextterminateself

可以先使用terminateSelf关闭页面，然后在回调中执行killAllProcesses，在后台杀掉所有进程。参考代码如下：

try {
  this.context.terminateSelf((err: BusinessError) => {
    let applicationContext = this.context.getApplicationContext();
    applicationContext.killAllProcesses();
    if (err.code) {
      console.error(`terminateSelf failed, code is ${err.code}, message is ${err.message}`);
      return;
    }
    console.info('terminateSelf succeed');
  });
} catch (err) { // 捕获同步的参数错误
  let code = (err as BusinessError).code;
  let message = (err as BusinessError).message;
  console.error(`terminateSelf failed, code is ${code}, message is ${message}`);
}
