Php 如何发布topicType优惠的localPost？

我正试图让谷歌成为我的业务localPost，以PHP提供topicType

我安装了google/apiclient 2.7。 另外，我有来自GMB站点的客户端库，如下所示。

我制作了以下源代码

  $offer = new \Google_Service_MyBusiness_LocalPostOffer();
  $offer->setCouponCode($couponCode);
  $offer->setTermsConditions($termsCondition);
  $offer->setRedeemOnlineUrl($redeemOnlineUrl);

  $schedule = new \Google_Service_MyBusiness_TimeInterval();
  $date = new \Google_Service_MyBusiness_Date();
  $date->setDay(6);
  $date->setMonth(10);
  $date->setYear(2020);

  $time = new  \Google_Service_MyBusiness_TimeOfDay();
  $time->setHours(10);
  $time->setMinutes(0);
  $time->setMinutes(0);
  $time->setSeconds(0);
  $time->setNanos(0);

  $schedule->setStartDate($date);
  $schedule->setStartTime($time);
  $date->setDay(6);
  $date->setMonth(10);
  $date->setYear(2020);
  $time->setHours(19);
  $time->setMinutes(0);
  $time->setSeconds(0);
  $time->setNanos(0);
  $schedule->setEndDate($date);
  $schedule->setEndTime($time);
  $event = new \Google_Service_MyBusiness_LocalPostEvent();
  $event->setTitle($title);
  $event->setSchedule($schedule);

  $post = new \Google_Service_MyBusiness_LocalPost();
  $post->setSummary($summary);
  $post->setOffer($offer);
  $post->setEvent($event);
  $post->setTopicType("OFFER");

  $obj = new \Google_Service_MyBusiness($this->getClient('mybusiness'));
  $obj->accounts_locations_localPosts->create($accountLocation,$post)

但是，它给我以下错误消息

{
  "error": {
    "code": 400,
    "message": "Request contains an invalid argument.",
    "errors": [
      {
        "message": "Request contains an invalid argument.",
        "domain": "global",
        "reason": "badRequest"
      }
    ],
    "status": "INVALID_ARGUMENT"
  }
}

你对此有什么建议吗

致以最诚挚的问候，

我无法发布报价的原因是我在设置endDate和endTime时没有重新初始化以下内容

Google_Service_MyBusiness_Date
Google_Service_MyBusiness_TimeOfDay

因此，我可能会重新初始化如下

  $date = new \Google_Service_MyBusiness_Date();
  $time = new  \Google_Service_MyBusiness_TimeOfDay()

这段代码为我创建了一个offer post

$service=新谷歌服务\我的业务（$client）；
$post\u body=new\Google\u Service\u MyBusiness\u LocalPost；
$post_body->setLanguageCode（'en'）；
$post_body->setSummary（'test offer_1'）；
$offer=new\Google\u Service\u MyBusiness\u LocalPostOffer；
$offer->setCouponCode（'TEST-OFFE-CODE'）；
$offer->setRecommensionOnlineURL（'https://www.example.com');
$offer->setTermsConditions（'offer无效，仅测试offer'）；
$post_body->setOffer（$offer）；
$event=new\Google\u Service\u MyBusiness\u LocalPostEvent；
$event->setTitle（'testoffer post'）；
$schedule=new\Google\u Service\u MyBusiness\u TimeInterval；
$startdate=new\Google\u Service\u MyBusiness\u时间间隔；
$date=new\Google\u Service\u MyBusiness\u date；
$date->setYear（'2021'）；
$date->setMonth（'10'）；
$date->setDay（'02'）；
$schedule->setStartDate（$date）；
$starttime=new\Google\u Service\u MyBusiness\u时间范围；
$time=new\Google\u Service\u MyBusiness\u TimeOfDay；
$time->setHours（'9'）；
$time->setMinutes（'0'）；
$time->setSeconds（'0'）；
$time->setNanos（'0'）；
$schedule->setStartTime（$time）；
$endDate=new\Google\u Service\u MyBusiness\u TimeInterval；
$date=new\Google\u Service\u MyBusiness\u date；
$date->setYear（'2021'）；
$date->setMonth（'10'）；
$date->setDay（'03'）；
$schedule->setEndDate（$date）；
$endtime=new\Google\u Service\u MyBusiness\u时间范围；
$time=new\Google\u Service\u MyBusiness\u TimeOfDay；
$time->setHours（'11'）；
$time->setMinutes（'0'）；
$time->setSeconds（'0'）；
$time->setNanos（'0'）；
$schedule->setEndTime（$time）；
$event->setSchedule（$schedule）；
$post_body->setEvent（$event）；
$post_body->setTopicType（'OFFER'）；
$media=new\Google\u Service\u MyBusiness\u MediaItem；
$media->setMediaFormat（'PHOTO'）；
$media->setSourceUrl（'https://image.shutterstock.com/image-photo/white-transparent-leaf-on-mirror-260nw-1029171697.jpg');
$post_body->setMedia（$media）；
$accounts=$service->accounts->listAccounts（）->getAccounts（）；
$locations=$service->accounts\u locations->listAccountsLocations（$accounts[0]['name']）；
$post=$service->accounts\u locations\u localPosts->create（$locations[0]['name']，$post\u body）；
