Redirect_uri_mismatch不起作用

Question

Hello,
i have issues with redirect URI, when i want to log in google oauth2, it doesnt redirect me and gimme Error 400: redirect_uri_mismatch

access_type=online
approval_prompt=auto
scope=https://www.googleapis.com/auth/calendar
response_type=code
redirect_uri=http://www.meetingroomapp.com/dashboard/oauth2callback.php
state=
client_id=825645938882-ftcv0fuojum9078uht1n8hpgbvp9ej3f.apps.googleusercont

There is code in index.php

if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
  $client->setAccessToken($_SESSION['access_token']);

SOME CODE HERE 

} else {
  $redirect_uri = 'http://www.meetingroomapp.com/dashboard/oauth2callback.php';
  header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}

There is code in oauth2callback.php

session_start();

$client = new Google_Client();
$client->setAuthConfigFile('client_secret.json');
$client->setRedirectUri('http://www.meetingroomapp.com/dashboard/');
$client->addScope("https://www.googleapis.com/auth/calendar");

if (! isset($_GET['code'])) { //přesměrování na google server
  $auth_url = $client->createAuthUrl();
  header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
} else {
  $client->authenticate($_GET['code']);
  $_SESSION['access_token'] = $client->getAccessToken();
  $redirect_uri = 'http://www.meetingroomapp.com/dashboard/';
  header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}

There is secret JSON

{"installed":{"client_id":"**ID**","project_id":"meetinroomapp","auth_uri":"https://accounts.google.com/o/oauth2/auth","token_uri":"https://accounts.google.com/o/oauth2/token","auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs","client_secret":"**SECRET**","redirect_uris":["urn:ietf:wg:oauth:2.0:oob","http://www.meetingroomapp.com/dashboard/"]}}

In Google developer console i have set http://www.meetingroomapp.com/dashboard/ as homepage

Answer 1

redirect mismatch happens when the redirect uri you specified in you request doesnt match the one you specified in google developer console.so check if the the redirect uri you specfied in google developer console is http://www.meetingroomapp.com/dashboard/oauth2callback.php
