SOAP Web サービスを使用してユーザー名とパスワードをチェックする単純な認証プラグインを作成しました。それはうまくいきます。
joomlaの管理者にSOAPパスワードのようなパラメーターが必要でした。そのため、xmlにパラメーターを追加しました。管理者に表示されます。その値をphpで取得しようとすると、次のようになります。
致命的なエラー: 非オブジェクトでのメンバー関数 get() の呼び出し
なので他の認証と比べてみたら全く同じようにやっているのですが……どうしてそうなるのかわかりません。
プラグインのコードは次のとおりです。
public function __construct() {
$nusoap = JPATH_SITE . '/plugins/authentication/ers/nusoap/lib/nusoap.php';
if (! file_exists ( $nusoap )){
$response->error_message = "No such file";
return;
}
require_once ($nusoap);
}
function onUserAuthenticate($credentials, $options, &$response)
{
//Without defaults (the plugin crashes on the first get() bellow)
$webservice = $this->params->get('webservice', '');
$group = $this->params->get('group', '');
$whitepaw = $this->params->get('whitepaw', '');
JRequest::checkToken() or die( 'Invalid Token' );
// For JLog
$response->type = 'ERS SOAP Webservice';
// MyCompany does not like blank passwords (So does Joomla ;))
if (empty($credentials['password'])) {
$response->status = JAuthentication::STATUS_FAILURE;
$response->error_message = JText::_('JGLOBAL_AUTH_EMPTY_PASS_NOT_ALLOWED');
return false;
}
if (empty($credentials['username'])) {
$response->status = JAuthentication::STATUS_FAILURE;
$response->error_message = JText::_('Please enter a username');
return false;
