使用curl的Facebook Graph-API - 创建带图片的事件失败

Question

I have tested the codes from this and this but it doesn't work.

The event is created successfully but the image is not published.

Here is my actual code:

require_once '../admini/config.php';

$t = getToken('appID', 'appSecret');

$file = 'Koala.jpg';
$arrData = array(
    'name' => 'Test Event',
    'start_time' => '2015-07-04', //ISO-8601 format - With Time  -     2012-07-04T19:00:00-0700
    //'end_time' => '', //optional
    'description' => 'Das erste Test-Event',
    'location' => 'Deggendorf', //Just a name
    'location_id' => '103091806397289', //place id - inserts a link to place fb page
    'ticket_url' => 'url', //URL to buy a ticket for the event
    'no_feed_story' => FALSE, //TRUE = dont display on page 
    'access_token' => 'token',
    'picture' => '@'. realpath($file),
    );
$createUrl = 'https://graph.facebook.com/page_id/events';


$test = fbcurl($createUrl, 'POST', $arrData); //Returns the event id

echo '<pre>';
print_r($test);
echo '</pre>';

function fbcurl($url, $method, $fields = array(), $auth = array()){

foreach($fields as $key => $value){
    if(!is_string($value)){
        $fields[$key] = json_encode($value);
    }
}

$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:multipart/form-data'));
//  curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
//  if(count($auth)===2)
//      curl_setopt($ch, CURLOPT_USERPWD, $auth['user'].':'.$auth['pass']);
//  }
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
if(count($fields)>0){
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($fields, null, '&'));

}
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
//curl_setopt($ch, CURLOPT_TIMEOUT, 60);

//curl_setopt($ch, CURLOPT_USERAGENT, 'facebook-php-3.2');
//curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "Content-Type: multipart/form-data");
    //file_put_contents('fbcurllocal.txt', print_r(http_build_query($fields, null,        '&'),      true)."
".$url);
$r = curl_exec($ch);
curl_close($ch);
if($r!=''){
    $p = explode("

HTTP/", $r);
    $p = (count($p) > 1 ? 'HTTP/' : '') . array_pop($p);
    list($h, $b) = explode("

", $p, 2);
    return array('header' => $h, 'body' => $b);
}else{
    return array('header' => '', 'body' => 'error');
}
}

Answer 1

If you read the documentation, ther's no such field picture with \POST /{page-id}/events.

So, while creating an event you can not publish a cover picture along with it. So it's a two-step procedure-

1. Create event

   API: \POST /{page-id}/events - Reference

   This you've already done, just delete the picture parameter from there.

2. Upload cover picture

   API: \POST /{event-id}/events - Reference

   Give the image to the parameter: source

This way you can upload the cover pic to an event. Hope that helps.

Edit

The method to upload cover photo that I've mentioned will not work as of now (you can subscribe to this bug to get the update), instead you'll be needing a link to the image and make the call-

\POST /{event-id}

Parameter: cover_url

This works. I've tested!
