您应该创建自己的 Zend_Auth_Adapter。该适配器将尝试对您的三个资源进行身份验证,并将其标记在私有成员变量中,以便您可以知道哪些登录尝试已成功通过身份验证。
要创建您的 Auth 适配器,您可以以 Zend_Auth_Adapter_DbTable 为基础。
因此,在 __construct 中,您可以传递每个资源中使用的三个适配器,而不是仅传递一个 DbTable 适配器。仅当每个适配器使用不同的资源(例如 LDAP,甚至另一个数据库)时,您才会采用这种方式,否则,您可以仅传递一个适配器并在配置选项中设置三个不同的表名称。
这是来自 Zend_Auth_Adapter_DbTable 的示例:
/**
* __construct() - Sets configuration options
*
* @param Zend_Db_Adapter_Abstract $zendDb
* @param string $tableName
* @param string $identityColumn
* @param string $credentialColumn
* @param string $credentialTreatment
* @return void
*/
public function __construct(Zend_Db_Adapter_Abstract $zendDb, $tableName = null, $identityColumn = null,
$credentialColumn = null, $credentialTreatment = null)
{
$this->_zendDb = $zendDb;
// Here you can set three table names instead of one
if (null !== $tableName) {
$this->setTableName($tableName);
}
if (null !== $identityColumn) {
$this->setIdentityColumn($identityColumn);
}
if (null !== $credentialColumn) {
$this->setCredentialColumn($credentialColumn);
}
if (null !== $credentialTreatment) {
$this->setCredentialTreatment($credentialTreatment);
}
}
下面的方法来自 Zend_Auth_Adapter_DbTable,尝试对一个表进行身份验证,您可以将其更改为在三个表中尝试,并且对于每个表,当您成功时,可以将其设置为私有成员变量中的标志。类似于 $result['group1'] = 1;您将为每次成功登录尝试设置 1。
/**
* authenticate() - defined by Zend_Auth_Adapter_Interface. This method is called to
* attempt an authentication. Previous to this call, this adapter would have already
* been configured with all necessary information to successfully connect to a database
* table and attempt to find a record matching the provided identity.
*
* @throws Zend_Auth_Adapter_Exception if answering the authentication query is impossible
* @return Zend_Auth_Result
*/
public function authenticate()
{
$this->_authenticateSetup();
$dbSelect = $this->_authenticateCreateSelect();
$resultIdentities = $this->_authenticateQuerySelect($dbSelect);
if ( ($authResult = $this->_authenticateValidateResultset($resultIdentities)) instanceof Zend_Auth_Result) {
return $authResult;
}
$authResult = $this->_authenticateValidateResult(array_shift($resultIdentities));
return $authResult;
}
仅当三个登录尝试之一成功通过身份验证时,您才会返回有效的 $authresult。
现在,在您的控制器中,尝试登录后:
public function loginAction()
{
$form = new Admin_Form_Login();
if($this->getRequest()->isPost())
{
$formData = $this->_request->getPost();
if($form->isValid($formData))
{
$authAdapter = $this->getAuthAdapter();
$authAdapter->setIdentity($form->getValue('user'))
->setCredential($form->getValue('password'));
$result = $authAdapter->authenticate();
if($result->isValid())
{
$identity = $authAdapter->getResult();
Zend_Auth::getInstance()->getStorage()->write($identity);
// redirect here
}
}
}
$this->view->form = $form;
}
private function getAuthAdapter()
{
$authAdapter = new MyAuthAdapter(Zend_Db_Table::getDefaultAdapter());
// Here the three tables
$authAdapter->setTableName(array('users','users2','users3'))
->setIdentityColumn('user')
->setCredentialColumn('password')
->setCredentialTreatment('MD5(?)');
return $authAdapter;
}
这里的关键是下面的行,它将在您的自定义身份验证适配器中实现:
$identity = $authAdapter->getResult();
您可以以此形式为基础 Zend_Auth_Adapter_DbTable:
/**
* getResultRowObject() - Returns the result row as a stdClass object
*
* @param string|array $returnColumns
* @param string|array $omitColumns
* @return stdClass|boolean
*/
public function getResultRowObject($returnColumns = null, $omitColumns = null)
{
// ...
}
成功通过身份验证后,这将返回登录尝试中匹配的行。
因此,您将创建可以返回该行以及 $this->result['groupX'] 标志的 getResult() 方法。
就像是:
public function authenticate()
{
// Perform the query for table 1 here and if ok:
$this->result = $row->toArrray(); // Here you can get the table result of just one table or even merge all in one array if necessary
$this->result['group1'] = 1;
// and so on...
$this->result['group2'] = 1;
// ...
$this->result['group3'] = 1;
// Else you will set all to 0 and return a fail result
}
public function getResult()
{
return $this->result;
}
毕竟您可以使用 Zend_Acl 来控制您的视图和其他操作。由于您将在 Zend Auth 存储中拥有这些标志,因此您可以将其用作角色:
$this->addRole(new Zend_Acl_Role($row['group1']));
