Question

I would like to understand why i get “The requested URL responded with HTTP code 401.” when i try to put a description whith an access token.

The weird think is it works fine when i do that just after getting the access_token (session) from the user, but when i store the token, and try to launch the same code later, it fail !

Apparantly, there is a problem with the token, because i can access the soundcloud description without token, but if i use this method: $soundcloud->setAccessToken($token); before getting the tracks datas, i can’t access them anymore…

Here is the code:

require_once 'soundcloud/Soundcloud.php';
$soundcloud = new Services_Soundcloud(SOUNDCLOUD_CLIENT_ID, SOUNDCLOUD_CLIENT_SECRET, SOUNDCLOUD_REDIRECT_URI);
$soundcloud->setAccessToken($session_token);
try
{
    $track = json_decode($soundcloud->get('tracks/'.$media_id), true);
}
catch (Services_Soundcloud_Invalid_Http_Response_Code_Exception $e)
{
    exit($e->getMessage());
}
try
{
    $response = json_decode($soundcloud->put(
                                     'tracks/'.$media_id,
                                              'test',
                                               array(CURLOPT_HTTPHEADER => array('Content-Type: application/xml'))), true);
}
catch (Services_Soundcloud_Invalid_Http_Response_Code_Exception $e)
{
    exit($e->getMessage());
}

This code works when i just get the token but fail if i launch it a few days later…

Thanks for help !

Where is $session_token coming from in this example? Depending on how you generated the access token, one of two things are happening:

1. You are not sending the correct access token.
2. The access token you are sending has expired.

If it’s 2, you should have gotten a refresh token when the user authorizes your app. The PHP SoundCloud SDK has a accessTokenRefresh() method that you can use in this scenario.
