fix #88 修正异常时的返回值类型，供下游正确解析，以反馈给用户

[g8up]

统一返回值数据结构，以便向下正常透传，供交互反馈正确解析。

解释

• 视图层触发上传、下载逻辑时，与背景页交互，期待的返回结果是

// ret
{
  message: 'xxx', // 'done' 或其他值
  note: 'xxx',
}

CookieCloud/extension/popup.tsx

Lines 13 to 39 in e631fa9

	async function test(action=browser.i18n.getMessage('test'))
	{
	console.log("request,begin");
	if( !data['endpoint'] || !data['password'] || !data['uuid'] || !data['type'] )
	{
	alert(browser.i18n.getMessage("fullMessagePlease"));
	return;
	}
	if( data['type'] == 'pause' )
	{
	// alert('暂停状态不能'+action);
	alert(browser.i18n.getMessage("actionNotAllowedInPause"));
	return;
	}
	const ret = await sendToBackground<RequestBody, ResponseBody>({name:"config",body:{payload:{...data,no_cache:1}}});
	console.log(action+"返回",ret);
	if( ret && ret['message'] == 'done' )
	{
	if( ret['note'] )
	alert(ret['note']);
	else
	alert(action+browser.i18n.getMessage('success'));
	}else
	{
	alert(action+browser.i18n.getMessage('failedCheckInfo'));
	}
	}

• 背景页响应时,会有个字段名的映射转换: action对应message
  

  CookieCloud/extension/background/messages/config.ts

  Lines 14 to 23 in e631fa9

  	export const handler: PlasmoMessaging.MessageHandler<RequestBody,
  	ResponseBody> = async (req, res) => {
  	// 获得cookie，并进行过滤
  	const payload = req.body.payload;
  	const result = (payload['type'] && payload['type'] == 'down') ? await download_cookie(payload) : await upload_cookie(payload);
  	res.send({
  	message: result['action'],
  	note: result['note'],
  	})
  	}

• 本次修改将upload_cookie()、download_cookie()的异常时的返回值数据结构统一成:

{
  action: 'xxx',
  note: 'xxx'
}
