// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// We previously obtained an access token and saved the JSON to a file using this example:
// Get Rabobank OAuth2 Access Token

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$json = new COM("Chilkat.JsonObject");
$success = $json->LoadFile('qa_data/tokens/rabobank.json');
if ($success != 1) {
    exit;
}

// {
//   "token_type": "Bearer",
//   "access_token": "AAIkYTU0ZWM ... sxE0KL0HHWw",
//   "expires_in": 3600,
//   "consented_on": 1584641121,
//   "scope": "ais.balances.read ais.transactions.read-90days ais.transactions.read-history",
//   "refresh_token": "AAJXXSdN ... Uiblz9ILkxNBlytRGA",
//   "refresh_token_expires_in": 157784760,
//   "expires_on": "1584644722"
// }

// Refresh the access token by sending a POST like this:
// 

// POST /oauth2/token
// Headers:
//     Content-Type: application/x-www-form-urlencoded
//     Authorization: Basic BASE64(CLIENT_ID + ":" + CLIENT_SECRET)
// 
// Body (x-www-form-urlencoded):
//     grant_type: refresh_token
//     refresh_token: REFRESH_TOKEN

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.HttpRequest')
$req = new COM("Chilkat.HttpRequest");
$req->AddParam('grant_type','refresh_token');
$req->AddParam('refresh_token',$json->stringOf('refresh_token'));

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Http')
$http = new COM("Chilkat.Http");

// Causes the "Authorization: Basic BASE64(CLIENT_ID + ":" + CLIENT_SECRET)" header to be added..
$http->BasicAuth = 1;
$http->Login = 'YOUR_APP_CLIENT_ID';
$http->Password = 'YOUR_APP_CLIENT_SECRET';

// resp is a Chilkat.HttpResponse
$resp = $http->PostUrlEncoded('https://api-sandbox.rabobank.nl/openapi/sandbox/oauth2/token',$req);
if ($http->LastMethodSuccess != 1) {
    print $http->LastErrorText . "\n";
    exit;
}

// Load the JSON response.
$json->Load($resp->BodyStr);
$json->EmitCompact = 0;

// Show the JSON response.
print $json->emit() . "\n";

print 'Response status code: ' . $resp->StatusCode . "\n";

// If the response status code is not 200, then it's an error.
if ($resp->StatusCode != 200) {
    exit;
}

// Save the refreshed access token JSON to a file for future requests.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.FileAccess')
$fac = new COM("Chilkat.FileAccess");
$fac->WriteEntireTextFile('qa_data/tokens/rabobank.json',$json->emit(),'utf-8',0);
