Google Calendar API InvalidArgumentException : "Invalid Code" - php

Question

Okay so far I've been following the listed php tutorial that Google has provided, I have gathered my client secret, I have set my Redirect URI to port localhost:8000 and have listed the directory for my credentials/client_secret accordingly. I'm now in the final step which is authorizing my application in order for me to be a productive spawn of society and use this fantastic calendar library.
I'm getting this error once in the stage of authorizing my account, (which is strange because I'm able to get the correct URL to authorize my application (the URL works and redirects to the correct URI) and get the code needed but I'm not able to input it in because it seems as if it takes in nothing willingly without waiting for me to put the code in):

bloody well right
here's where it's throwing the exception (API's\vendor\google\apiclient\src\Google\Client.php on line 176):
public function fetchAccessTokenWithAuthCode($code)
{
if (strlen($code) == 0) {
throw new InvalidArgumentException("Invalid code"); //exception thrown here
}
$auth = $this->getOAuth2Service();
$auth->setCode($code);
$auth->setRedirectUri($this->getRedirectUri());
$httpHandler = HttpHandlerFactory::build($this->getHttpClient());
$creds = $auth->fetchAuthToken($httpHandler);
if ($creds && isset($creds['access_token'])) {
$creds['created'] = time();
$this->setAccessToken($creds);
}
return $creds;
}
is there something wrong with my credentials? I have but a clue what may be going on because I've tried in the past and have never experienced this error, I usually get something along the lines of the redirect URI not being correct. Any and all help is welcome. TYIA.

Answer 1

I think you are going about it the wrong way remember code is only used once its is an authorization code after that you will need to either store the refresh token or require that the user login again once it has expired.
oauth2callback.php
<?php
// Load the Google API PHP Client Library.
require_once __DIR__ . '/vendor/autoload.php';
// Start a session to persist credentials.
session_start();
// Create the client object and set the authorization configuration
// from the client_secrets.json you downloaded from the Developers Console.
$client = new Google_Client();
$client->setAuthConfig(__DIR__ . '/client_secrets.json');
$client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php');
$client->addScope(Google_Service_Calendar::CALENDAR_READONLY);
// Handle authorization flow from the server.
if (! isset($_GET['code'])) {
$auth_url = $client->createAuthUrl();
header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
} else {
$client->authenticate($_GET['code']);
$_SESSION['access_token'] = $client->getAccessToken();
$redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/';
header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}
index.php
<?php
// Load the Google API PHP Client Library.
require_once __DIR__ . '/vendor/autoload.php';
session_start();
$client = new Google_Client();
$client->setAuthConfig(__DIR__ . '/client_secrets.json');
$client->addScope(Google_Service_Calendar::CALENDAR_READONLY);
// If the user has already authorized this app then get an access token
// else redirect to ask the user to authorize access to Google Analytics.
if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
// Set the access token on the client.
$client->setAccessToken($_SESSION['access_token']);
// Create an authorized analytics service object.
$service= new Google_Service_Calendar($client);
// Call The method which will call the Api
$response = getCalendar($service);
// Print the response.
printResults($response);
} else {
$redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php';
header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}
I have another example where which shows how to store the refresh token. Calendar api sample
