Facebook Scraping返回错误500

Question

I'm using https://developers.facebook.com/tools/debug to determine what facebook sees from my page.

When I'm doing for my page, a Facebook scrape is returning a 500 error only because of this line

$photoObj=$facebook->api("/$photoId?access_token=$access_token");

although the page is executing correctly??

Any idea??

Answer 1

I've changed the technique of retrieving the image, now I do it like this:

$access_token=$facebook->getAccessToken();
$photoObj=file_get_contents("https://graph.facebook.com/$photoId?access_token=$access_token");
$photoObj=json_decode($photoObj);
$picURL=$photoObj->source;

and it works :-)
