How to write a Dropbox Curl request in PHP Curl?-CodePudding

good afternoon! I'm newer in Php programming and I would that someone helps me how to write this refresh token request from Dropbox API in Php Curl. I already read the official documentation about PHP Curl but i didn't achieved to understand it.

The Dropbox API request in Curl (terminal):

curl https://api.dropbox.com/oauth2/token \ 
     -d grant_type=refresh_token \
     -d refresh_token=<REFRESH_TOKEN> \
     -u <APP_KEY>:<APP_SECRET>

Where <APP_KEY>, <APP_SECRET> and REFRESH_TOKEN are credentials gotten from Dropbox.

How do I write this in PHP Curl?

Its will return a json output whit the new Oauth2 Access Token from Dropbox, I want to learn how to handle this output.

CodePudding user response：

For a beginner in PHP Http request, you can use this Curl to PHP Curl translate, Wich takes your Curl request and translate it to PHP code.

This has worked very well for me.

See how the your Curl command was in PHP

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'https://api.dropbox.com/oauth2/token');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=refresh_token&refresh_token=<REFRESH_TOKEN>");
curl_setopt($ch, CURLOPT_USERPWD, '<APP_KEY>' . ':' . '<APP_SECRET>');

$headers = array();
$headers[] = 'Content-Type: application/x-www-form-urlencoded';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close($ch);
