上手OAuthException：将照片发布到目标相册后发生未知错误

Question

$photo_details = array(
        'message'=> $image->description().' '.$site_adr.$image->id().'/'.cleanSEOstring(strtolower(trim($image->title()))).'-cover-photo',
        'redirect_uri'=> 'http://www.exampleurl.com',
        'scope'=>'publish_stream');
$photo_details['image'] = '@' . realpath($photo);
    try
    {
        $upload_photo = $facebook->api('/'.$album_uid.'/photos', 'POST', $photo_details);
        @unlink($file);
        header('location:https://www.facebook.com/profile.php?id='.$userMe['id'].'&v=wall');
    }
    catch(FacebookApiException $e)
    {
        header('location:http://www.somethingwentwrong.com');
    }

And it still redirects to somethingwentwrong.com, am I doing something wrong?

The exception, as stated in the title is "An unknwon error has occured", here's the object it returnes in the catch statement:

object(FacebookApiException)#5 (7) { ["result:protected"]=> array(1) { ["error"]=> array(3) { ["message"]=> string(30) "An unknown error has occurred." ["type"]=> string(14) "OAuthException" ["code"]=> int(1) } } ["message:protected"]=> string(30) "An unknown error has occurred." ["string:private"]=> string(0) "" ["code:protected"]=> int(0) ["file:protected"]=> string(48) "/var/www/mysite/fb-sdk/base_facebook.php" ["line:protected"]=> int(1106) ["trace:private"]=> array(4) { [0]=> array(6) { ["file"]=> string(48) "/var/www/mysite/fb-sdk/base_facebook.php" ["line"]=> int(810) ["function"]=> string(17) "throwAPIException" ["class"]=> string(12) "BaseFacebook" ["type"]=> string(2) "->"

Answer 1

Find out what the exception error message is. So do something like this:

} catch {
  error_log('caught exception: '. $e);
  header('location:http://www.somethingwentwrong.com');
}

If you get OAuthException: (#803) Some of the aliases you requested do not exist then make sure $album_uid is a string and not an int.

Also make sure the user has given your app the user_photos permission. The exception error message will tell you.

If you are trying to post a photo to an FB Page, you need to use a Page Access Token.

Your code looks ok, except I think 'scope' and 'redirect_uri' won't do anything to the Graph API call.

I don't think this is your fault. I've been seeing a very similar issue lately, photo uploads are failing with "an unknown error has occurred". This is happening randomly across all of our client accounts, but most frequently on two accounts (80-90% of uploads fail). Sometimes retrying the upload will solve the problem but it usually fails as well.

I've opened a ticket on Facebook Developers area on 9/13. Please add your repro so it gains traction.
