Facebook Marketing API (php SDK) 'invalid parameter' for AdCreative

Question

我试图让营销API的例子与PHP SDK工作。我已经设法创建一个活动，设置目标，上传图像和创建AdSet。然而，我对AdCreative和广告本身感到困惑。

代码不断打破'无效参数'，但我不知道哪一个是无效的。我已经调试了3天了，还是卡住了。下面是我的代码:

创建活动:

$campaign = new Campaign(null, 'act_xxxxxxx');
$campaign->setData(array(
  CampaignFields::NAME => '#My Campaign#',
  CampaignFields::OBJECTIVE => CampaignObjectiveValues::LINK_CLICKS,
));
$campaign->create(array(
  Campaign::STATUS_PARAM_NAME => Campaign::STATUS_PAUSED,
));

创建目标受众:

$targeting = new Targeting();
$targeting->{TargetingFields::GEO_LOCATIONS} =
  array(
    'location_types' => array('recent'),
    'custom_locations' => array(
                            array(
                                'latitude'=> 'xx.xxxxxxx',
                                 'longitude'=> 'xx.xxxxxxx',
                                  'radius'=> 2,
                                   'distance_unit'=> 'kilometer')),
  );

创建Adset:

$start_time = (new DateTime("+1 day"))->format(DateTime::ISO8601);
$end_time = (new DateTime("+2 day"))->format(DateTime::ISO8601);
$adset = new AdSet(null, 'act_xxxxxxxx');
$adset->setData(array(
  AdSetFields::NAME => '#My Adset#',
  AdSetFields::OPTIMIZATION_GOAL => AdSetOptimizationGoalValues::LINK_CLICKS,
  AdSetFields::BILLING_EVENT => AdSetBillingEventValues::LINK_CLICKS,
  AdSetFields::BID_AMOUNT => 2,
  AdSetFields::DAILY_BUDGET => 500,
  AdSetFields::CAMPAIGN_ID => $campaign->id,
  AdSetFields::TARGETING => $targeting,
  AdSetFields::START_TIME => $start_time,
  AdSetFields::END_TIME => $end_time,
));
$adset->create(array(
  AdSet::STATUS_PARAM_NAME => AdSet::STATUS_PAUSED,
));

上传图片:

$image = new AdImage(null, 'act_xxxxxxxx');
$image->{AdImageFields::FILENAME} = 'fb-ad-images/xxxxx.jpeg';
$image->create();
$img_hash=$image->{AdImageFields::HASH}.PHP_EOL;

创建AdCreative:

$link_data = new AdCreativeLinkData();
$link_data->setData(array(
  AdCreativeLinkDataFields::MESSAGE => 'try it out',
  AdCreativeLinkDataFields::LINK => 'http://example.com',
  AdCreativeLinkDataFields::CAPTION => 'My caption',
  AdCreativeLinkDataFields::IMAGE_HASH => $img_hash,
));
$object_story_spec = new AdCreativeObjectStorySpec();
$object_story_spec->setData(array(
  AdCreativeObjectStorySpecFields::PAGE_ID => xxxxxxxxxxxxxxx,
  AdCreativeObjectStorySpecFields::LINK_DATA => $link_data,
));
$creative = new AdCreative(null, 'act_xxxxxxx');
$creative->setData(array(
  AdCreativeFields::NAME => 'Sample Creative',
  AdCreativeFields::OBJECT_STORY_SPEC => $object_story_spec,
));
$creative->create();

创建广告:

$data = array(
  AdFields::NAME => 'My Ad',
  AdFields::ADSET_ID => $adset->id,
  AdFields::CREATIVE => array(
    'creative_id' => $creative->id,
  ),
);
$ad = new Ad(null, 'act_xxxxxx');
$ad->setData($data);
$ad->create(array(
  Ad::STATUS_PARAM_NAME => Ad::STATUS_PAUSED,
));

我已经检查了参数的验证兼容性，一切似乎都没问题。错误是

Fatal error: Uncaught exception 'FacebookAdsHttpExceptionAuthorizationException' with message 'Invalid parameter'

谁能帮帮我，我真的卡住了。谢谢。

查看您的代码，看起来您没有在Targeting中指定经度和纬度。xx。XXX需要替换为文本。我发现的方法是通过在代码中启用日志记录并获得指示错误的实际API调用。请看一下更新后的代码片段。

<?php
$access_token = '<ACCESS_TOKEN>';
$app_id = <APP_ID>;
$app_secret = '<APP_SECRET>';
// should begin with "act_" (eg: $account_id = 'act_1234567890';)
$account_id = 'act_<Ad_ACCOUNT_ID>';
// Configurations - End
if (is_null($access_token) || is_null($app_id) || is_null($app_secret)) {
  throw new Exception(
    'You must set your access token, app id and app secret before executing'
  );
}
if (is_null($account_id)) {
  throw new Exception(
    'You must set your account id before executing');
}
define('SDK_DIR', __DIR__ . '/..'); // Path to the SDK directory
$loader = include SDK_DIR.'/vendor/autoload.php';
use FacebookAdsApi;
use FacebookAdsLoggerCurlLogger;
Api::init($app_id, $app_secret, $access_token);
// Create the CurlLogger
$logger = new CurlLogger();
// To write to a file pass in a file handler
// $logger = new CurlLogger(fopen('test','w'));
// Attach the logger to the Api instance
Api::instance()->setLogger($logger);
use FacebookAdsObjectCampaign;
use FacebookAdsObjectFieldsCampaignFields;
use FacebookAdsObjectValuesCampaignObjectiveValues;
use FacebookAdsObjectTargeting;
use FacebookAdsObjectFieldsTargetingFields;
use FacebookAdsObjectFieldsAdSetFields;
use FacebookAdsObjectAdSet;
use FacebookAdsObjectValuesAdSetOptimizationGoalValues;
use FacebookAdsObjectValuesAdSetBillingEventValues;
$campaign = new Campaign(null, $account_id);
$campaign->setData(array(
  CampaignFields::NAME => '#My Campaign#',
  CampaignFields::OBJECTIVE => CampaignObjectiveValues::LINK_CLICKS,
));
$campaign->create(array(
  Campaign::STATUS_PARAM_NAME => Campaign::STATUS_PAUSED,
));
$targeting = new Targeting();
$targeting->{TargetingFields::GEO_LOCATIONS} =
  array(
    'location_types' => array('recent'),
    'custom_locations' => array(
                            array(
                                'latitude'=> '47.6062',
                                 'longitude'=> '122.3321',
                                  'radius'=> 2,
                                   'distance_unit'=> 'kilometer')),
  );
$start_time = (new DateTime("+1 day"))->format(DateTime::ISO8601);
$end_time = (new DateTime("+2 day"))->format(DateTime::ISO8601);
echo $campaign->id."n";
$adset = new AdSet(null, $account_id);
$adset->setData(array(
  AdSetFields::NAME => '#My Adset#',
  AdSetFields::OPTIMIZATION_GOAL => AdSetOptimizationGoalValues::IMPRESSIONS,
  AdSetFields::BILLING_EVENT => AdSetBillingEventValues::IMPRESSIONS,
  AdSetFields::BID_AMOUNT => 2,
  AdSetFields::DAILY_BUDGET => 500,
  AdSetFields::CAMPAIGN_ID => $campaign->id,
  AdSetFields::TARGETING => $targeting,
  AdSetFields::START_TIME => $start_time,
  AdSetFields::END_TIME => $end_time,
));
$adset->create(array(
  AdSet::STATUS_PARAM_NAME => AdSet::STATUS_PAUSED,
));

在我看来，指定经度和纬度不是问题。我建议直接从开发人员工具资源管理器检查错误信息:https://developers.facebook.com/tools/explorer

我用相同的参数准备了请求，响应是:

{
  "error": {
    "message": "Invalid parameter",
    "type": "OAuthException",
    "code": 100,
    "error_subcode": 1885183,
    "is_transient": false,
    "error_user_title": "Ads creative post was created by an app that is in development mode",
    "error_user_msg": "Ads creative post was created by an app that is in development mode. It must be in public to create this ad."
  }
}

所以后面的原因很清楚
