FACEBOOK GRAPH API错误：redirect_uri URL必须是绝对的

Question

I try to practice this code Scenario 1: Uploading a photo to the app’s album

And there is error: The redirect_uri URL must be absolute

I just edit these sentences.

$app_id = "2***********02";
$app_secret = "******************edf965";
$post_login_url = "localhost/curl_prac/14.0_edition/testfb2.php";

Is it because I can't use localhost??

Please tell me what's wrong.Thank you.

Answer 1

Yes you cannot upload a photo from localhost you have to put a 'placeholder' real image url for your tests Moreover you are giving a relative path not an absolute one so you must be using the 'picture' parameter, either supply an absolute path or use the 'url' parameter instead.

I've never tried something like 'C://path/to/image' tho it could work.
