I can't download my files with PHP Core API

I have a Dropbox basic account, and these are my download codes. But I cant download my files with core API. Please help me .

require_once "lib/Dropbox/autoload.php";
use \Dropbox as dbx;
$appInfo = dbx\AppInfo::loadFromJsonFile("app-info.json");
$webAuth = new dbx\WebAuthNoRedirect($appInfo, "PHP-Example/1.0");

$authorizeUrl = $webAuth->start();

$accessToken = '<ACCESS_TOKEN>';

$dbxClient = new dbx\Client($accessToken, "PHP-Example/1.0");

$f = fopen("2016-2017-bahar-donemi-bilgisayar-muhendisligi-ders-programi.xls", "w+b");
$fileMetadata = $dbxClient->getFile("/2016-2017-bahar-donemi-bilgisayar-muhendisligi-ders-programi.xls", $f);
fclose($f);

Thanks for following up with the additional information. If you're seeing the file metadata as you describe, that means the API call itself worked.

When using that getFile method like this, the file data is saved to the file object supplied by to the resource $outStream parameter. In your case, that's your $f file object. Once that method completes successfully, you can then read the data from that file, which in your case is at the path "tufek.jpg".

and I can see tüfek.jpg details with an array.

note : I dont see any error . Just reloading page , I can see my files like a list and no more. I expect download tufek.jpg but no , its not download.

Ok , I got a new token and I can use it. I can upload any file or I can list my dropbox files. But I cant download my files. I am adding codes again without access token.

require_once "lib/Dropbox/autoload.php";
use \Dropbox as dbx;
$appInfo = dbx\AppInfo::loadFromJsonFile("app-info.json");
$webAuth = new dbx\WebAuthNoRedirect($appInfo, "PHP-Example/1.0");

$authorizeUrl = $webAuth->start();

$accessToken = '<ACCESS_TOKEN>'; //secret

$dbxClient = new dbx\Client($accessToken, "PHP-Example/1.0");

$f = fopen("tufek.jpg", "w+b");
$fileMetadata = $dbxClient->getFile("/tufek.jpg", $f); /*I cant download*/
fclose($f);
print_r($fileMetadata);

$metaData = $dbxClient->getMetadataWithChildren("/");

foreach($metaData['contents'] as $file){ // I can list my files
    $f = str_replace("/", "", $file['path']);
    echo "<div style='text-align:center; margin-top:25px;'><li>$f</li></div>";
}

By new access token, I mean you should retrieve another. This won't be any different that the old one, except that the old one is now revoked.

It is important that the old one was revoked because you posted it publicly, meaning any person could have taken it and accessed your account.

Once you have a working access token again, let us know the error message you get when you try to download a file. (Just don't post the new access token itself.)

What is the difference between new and old access tokens ? Why I should take a new one ? Old token perfectly uploaded my files but didnt download any file . I should try new access token ? Please let me know can all users upload files and download files with my Dropbox basic account ? I respect your business but I am going to crazy . I think I will delete my dropbox account

Greg-DB

Are you running the version with "<ACCESS_TOKEN>", or did you just redact your access token like that for posting the error here?

That's not a valid access token, and since you revoked the app, you'll need to retrieve a new access token to run your code. Make sure you use your access token exactly as provided, that is, just the long string without < or >.

Ok , I revoked API. When I continue with my codes , I get this error.

Fatal error: Uncaught InvalidArgumentException: 'accessToken' invalid: contains invalid character in C:\xampp\htdocs\17subat\lib\Dropbox\Client.php:1473 Stack trace: #0 C:\xampp\htdocs\17subat\lib\Dropbox\Client.php(78): Dropbox\Client::checkAccessTokenArg('accessToken', '<ACCESS_TOKEN>') #1 C:\xampp\htdocs\17subat\indirme.php(118): Dropbox\Client->__construct('<ACCESS_TOKEN>', 'PHP-Example/1.0') #2 {main} thrown in C:\xampp\htdocs\17subat\lib\Dropbox\Client.php on line 1473

To revoke an app, click the 'x' at the far right of the app's row.

Ok , I clicked that links but I cant find revoke option

Greg-DB

I redacted your access token from your post, but you should revoke it now since it was publicly posted. You can do so by revoking access to the app entirely, if the access token is for your account, here:

https://www.dropbox.com/account/security

Or, you can disable just this access token using the API:

v1: https://www.dropbox.com/developers/core/docs#disable-token
v1 PHP SDK: https://dropbox.github.io/dropbox-sdk-php/api-docs/v1.1.x/class-Dropbox.Client.html#_disableAccessToken
v2: https://www.dropbox.com/developers/documentation/http/documentation#auth-token-revoke

Also, note that the SDK you're using uses API v1, which is deprecated:

https://blogs.dropbox.com/developers/2016/06/api-v1-deprecated/

You should switch to API v2 whenever possible. For PHP, you can either use a third party library:

Or use the HTTPS endpoints directly:
