Question

我正在尝试制作广告素材但收到无效参数错误。例外甚至没有指定哪个参数错误。

try {
     $link_data = new AdCreativeLinkData();
     $link_data->setData(array(
           AdCreativeLinkDataFields::MESSAGE => 'try it out',
           AdCreativeLinkDataFields::LINK => 'http://www.google.com',
           AdCreativeLinkDataFields::IMAGE_HASH => '704e55dbf724243acfb8457a4f68a92a',
         ));

     $object_story_spec = new AdCreativeObjectStorySpec();
     $object_story_spec->setData(array(
           AdCreativeObjectStorySpecFields::LINK_DATA => $link_data,
     ));

     $creative = new AdCreative(null, 'act_576834712392068');

     $creative->setData(array(
           AdCreativeFields::NAME => 'Sample Creative Suite CRM',
           AdCreativeFields::OBJECT_STORY_SPEC => $object_story_spec,
     ));
     $creative->create();
} 
catch (Exception $e) {
  echo 'Caught exception: ',  $e, "\n";
}

抓住异常：异常＆＃39; FacebookAds \ HTTP \异常\ AuthorizationException＆＃39;与消息＆＃39;参数无效＆＃39;

Answer 1

您似乎尚未添加必须发布广告素材的网页。我认为在AdCreativeObjectStorySpecFields::PAGE_ID => 'your published page id here'中添加object_story_spec array可以解决您的问题。

Answer 2

不要忘记将应用的状态设置为从开发中激活。这是同样失败的原因。您可以使用

更详细地检查错误

catch (Exception $e) {
    var_dump($e)
}

广告素材获取错误＆＃34;无效参数＆＃34; Facebook营销API
