Question

我想用api创建一个创意。当我发布object_story_spec参数时，我收到此错误'Creative spec必须是关联数组（可选择json编码）'

这是我的json值，它是有效的。

{ "page_id" : "103830656322074", "link_data": { "call_to_action": {"type":"LEARN_MORE","value":{"link":"facebook.com/"}}, "caption": "Reklam #1", "name": "Reklam #1", "link": "facebook.com/", "message": "facebook.com/" }}

Answer 1

它应该是一样的东西。

object_story_spec={ 
                    "page_id": "<PAGE_ID>", 
                    "video_data": { 
                      "call_to_action": {"type":"LIKE_PAGE","value":{"page":"<PAGE_ID>"}}, 
                      "description": "try it out", 
                      "image_url": "<THUMBNAIL_URL>", 
                      "video_id": "<VIDEO_ID>" 
                    } 
                  }


Or

$object_story_spec = new ObjectStorySpec();
        $object_story_spec->setData(array(
            ObjectStorySpecFields::PAGE_ID => <PAGE_ID>,
            ObjectStorySpecFields::LINK_DATA => <LINK_DATA>,
        ));

 $creative = new AdCreative(null, 'ad_Acount_id');
        $creative->setData(array(
            AdCreativeFields::NAME => 'Sample Creative',
            AdCreativeFields::OBJECT_STORY_SPEC => $object_story_spec,
        ));

Answer 2

你应该在传递到下面的广告素材之前对$ object_story_spec进行网址添加。 no main manifest attribute, in Main.jar

$object_story_spec = urlencode($object_story_spec);
$creative = new AdCreative(null, 'ad_Acount_id');
        $creative->setData(array(
            AdCreativeFields::NAME => 'Sample Creative',
            AdCreativeFields::OBJECT_STORY_SPEC => $object_story_spec,
        ));

只需将定位字段转换为字符串，例如，如果您使用请求：

import requests
params = {
    'name': 'My Ad Set',
    'optimization_goal': 'LINK_CLICKS',
    'billing_event': 'IMPRESSIONS',
    'bid_amount': 2,
    'daily_budget': 100,
    'campaign_id': campaign_id,
    "targeting": str({
            "age_max": 65,
            "age_min": 18,
            "flexible_spec": [..]
    }),
    'start_time': datetime.now().strftime("%Y-%m-%dT%H:%M:%SZ"),
    'status': 'PAUSED',
    'access_token': access_token,
}

response = requests.post(
    url=f'https://graph.facebook.com/v11.0/act_{ad_account_id}/adsets',
    params=params
)

object_story_spec规范必须是关联数组
