源端设备的onContinue应该怎么写？

Question

A设备利用startAbility拉起B设备的UIAbility时，A设备page里的代码如下：

let bundleFlag = bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_HAP_MODULE
         let bundleInfo = bundleManager.getBundleInfoForSelfSync(bundleFlag)
         let want: Want = {
            deviceId: AppStorage.get('selectDeviceId') as string,
            bundleName: bundleInfo.name,
            moduleName: bundleInfo.hapModulesInfo[0].name,
            abilityName: 'EntryAbility',
            parameters: { selectMusicIndex: AppStorage.get('selectMusicIndex') as number }
         }
         hilog.debug(0x0001, 'RemoteDeviceManager_send', JSON.stringify(want.deviceId))
         hilog.debug(0x0001, 'RemoteDeviceManager_send', JSON.stringify(want.bundleName))
         hilog.debug(0x0001, 'RemoteDeviceManager_send', JSON.stringify(want.moduleName))
         hilog.debug(0x0001, 'RemoteDeviceManager_send', JSON.stringify(want.abilityName))
         hilog.debug(0x0001, 'RemoteDeviceManager_send', JSON.stringify(want.parameters))
         let context = getContext(this) as common.UIAbilityContext
         context.startAbility(want)
            .then(() => hilog.debug(0x0001, 'RemoteDeviceManager_send', 'send success'))
            .catch((error: BusinessError) => hilog.debug(0x0001, 'RemoteDeviceManager_send', JSON.stringify(error)))

A设备UIAbility的onContinue如下：

onContinue(wantParam: Record<string, number>): AbilityConstant.OnContinueResult {
      //
      return AbilityConstant.OnContinueResult.AGREE
   }

我在startAbility时已经保存了参数，onContinue里还需要保存吗？如果需要，应该怎么写才能保存参数？

目前onContinue还没写，A设备startAbility时会报错，错误码401，官网文档错误码链接：通用错误码401

在这种情况下，onContinue是否需要保存参数取决于你的具体业务需求。如果在后续的业务逻辑中需要用到这些参数，那么可以在 onContinue中进行保存。以下是一个示例，展示如何在 onContinue中处理参数保存：

onContinue(wantParam: Record<string, number>): AbilityConstant.OnContinueResult {
   AppStorage.set('passedParameters', wantParam);
   return AbilityConstant.OnContinueResult.AGREE;
}
