So this code I found below doesn't work I get to the authenticate screen then when t redirects me it just says Not logged in, Login in again. Does anyone know what I have to do to fix this? I am not very good at OATH2 and would like someone to walk me through.
I used the code from this gist.
<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
ini_set('max_execution_time', 300); //300 seconds = 5 minutes. In case if your CURL is slow and is loading too much (Can be IPv6 problem)
error_reporting(E_ALL);
define('OAUTH2_CLIENT_ID', '1234567890');
define('OAUTH2_CLIENT_SECRET', 'verysecretclientcode');
$authorizeURL = 'https://discord.com/api/oauth2/authorize';
$tokenURL = 'https://discord.com/api/oauth2/token';
$apiURLBase = 'https://discord.com/api/users/@me';
session_start();
// Start the login process by sending the user to Discord's authorization page
if(get('action') == 'login') {
$params = array(
'client_id' => OAUTH2_CLIENT_ID,
'redirect_uri' => 'https://yoursite.location/ifyouneedit',
'response_type' => 'code',
'scope' => 'identify guilds'
);
// Redirect the user to Discord's authorization page
header('Location: https://discordapp.com/api/oauth2/authorize' . '?' . http_build_query($params));
die();
}
// When Discord redirects the user back here, there will be a "code" and "state" parameter in the query string
if(get('code')) {
// Exchange the auth code for a token
$token = apiRequest($tokenURL, array(
"grant_type" => "authorization_code",
'client_id' => OAUTH2_CLIENT_ID,
'client_secret' => OAUTH2_CLIENT_SECRET,
'redirect_uri' => 'https://yoursite.location/ifyouneedit',
'code' => get('code')
));
$logout_token = $token->access_token;
$_SESSION['access_token'] = $token->access_token;
header('Location: ' . $_SERVER['PHP_SELF']);
}
if(session('access_token')) {
$user = apiRequest($apiURLBase);
echo '<h3>Logged In</h3>';
echo '<h4>Welcome, ' . $user->username . '</h4>';
echo '<pre>';
print_r($user);
echo '</pre>';
} else {
echo '<h3>Not logged in</h3>';
echo '<p><a href="?action=login">Log In</a></p>';
}
if(get('action') == 'logout') {
// This must to logout you, but it didn't worked(
$params = array(
'access_token' => $logout_token
);
// Redirect the user to Discord's revoke page
header('Location: https://discordapp.com/api/oauth2/token/revoke' . '?' . http_build_query($params));
die();
}
function apiRequest($url, $post=FALSE, $headers=array()) {
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$response = curl_exec($ch);
if($post)
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
$headers[] = 'Accept: application/json';
if(session('access_token'))
$headers[] = 'Authorization: Bearer ' . session('access_token');
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$response = curl_exec($ch);
return json_decode($response);
}
function get($key, $default=NULL) {
return array_key_exists($key, $_GET) ? $_GET[$key] : $default;
}
function session($key, $default=NULL) {
return array_key_exists($key, $_SESSION) ? $_SESSION[$key] : $default;
}
?>
EDIT: Basically in the if statement it doesn't go into the logged-in part.
Here is a working solution
<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
session_start();
$SecretHERE = "";
$IDHERE = "";
if (isset($_GET["error"])) {
echo json_encode(array("message" => "Authorization Error"));
} elseif (isset($_GET["code"])) {
$redirect_uri = "https://www.devtest.net/v4/login.php";
$token_request = "https://discordapp.com/api/oauth2/token";
$token = curl_init();
curl_setopt_array($token, array(
CURLOPT_URL => $token_request,
CURLOPT_POST => 1,
CURLOPT_POSTFIELDS => array(
"grant_type" => "authorization_code",
"client_id" => $IDHERE,
"client_secret" => $SecretHERE,
"redirect_uri" => $redirect_uri,
"code" => $_GET["code"]
)
));
curl_setopt($token, CURLOPT_RETURNTRANSFER, true);
$resp = json_decode(curl_exec($token));
curl_close($token);
if (!isset($_SESSION['user']) || !isset($_SESSION['userguilds'])) {
if (isset($resp->access_token)) {
$access_token = $resp->access_token;
$info_request = "https://discordapp.com/api/users/@me";
$info_request_guilds = "https://discord.com/api/users/@me/guilds";
$info = curl_init();
curl_setopt_array($info, array(
CURLOPT_URL => $info_request,
CURLOPT_HTTPHEADER => array(
"Authorization: Bearer {$access_token}"
),
CURLOPT_RETURNTRANSFER => true
));
$user = json_decode(curl_exec($info));
curl_close($info);
// GUILDS REQUEST
$info_guilds = curl_init();
curl_setopt_array($info_guilds, array(
CURLOPT_URL => $info_request_guilds,
CURLOPT_HTTPHEADER => array(
"Authorization: Bearer {$access_token}"
),
CURLOPT_RETURNTRANSFER => true
));
$guilds = json_decode(curl_exec($info_guilds));
curl_close($info_guilds);
$_SESSION['user'] = $user;
if ($_SESSION['user']->verified == 1) {
$_SESSION['userguilds'] = $guilds;
$_SESSION['avatar'] = "https://cdn.discordapp.com/avatars/" . $user->id . "/" . $user->avatar . ".png";
header("Location: https://www.devtest.net/v4/fork.php");
die();
}else{
print_r("Please verify your Discord Account.");
session_destroy();
die();
}
} else {
echo json_encode(array("message" => "Authentication Error"));
}
} else{
// They are already logged in so redirect them to fork.php
header("Location: https://www.devtest.net/v4/fork.php");
die();
}
} else {
// Redirect to Discord Oauth2 URL (CAN BE FOUND IN DISCORD DEV PORTAL)
header('location: https://discord.com/api/oauth2/authorize?client_id=CLIENTIDHERE&redirect_uri=https%3A%2F%2Fwww.devtest.net%2Fv4%2Flogin.php&response_type=code&scope=identify%20email%20connections%20guilds%20guilds.join');
die();
}
