use Firebase\JWT\JWT;

// Get your service account's email address and private key from the JSON key file
$service_account_email = "abc-123@a-b-c-123.iam.gserviceaccount.com";

function create_custom_token($uid, $is_premium_account) {
  global $service_account_email, $private_key;

  $now_seconds = time();
  $payload = array(
    "iss" => $service_account_email,
    "sub" => $service_account_email,
    "aud" => "https://identitytoolkit.googleapis.com/google.identity.identitytoolkit.v1.IdentityToolkit",
    "iat" => $now_seconds,
    "exp" => $now_seconds+(60*60),  // Maximum expiration time is one hour
    "uid" => $uid,
    "claims" => array(
      "premium_account" => $is_premium_account

  return JWT::encode($payload, $private_key, "RS256");

使用ruby-jwt ：

require "jwt"

$service_account_email = "service-account@my-project-abc123.iam.gserviceaccount.com"
$private_key = OpenSSL::PKey::RSA.new "-----BEGIN PRIVATE KEY-----\n..."

def create_custom_token(uid, is_premium_account)
  now_seconds = Time.now.to_i
