[英]Get email address from OpenID provider using Janrain OpenID library
当我使用Google登录到StackOverflow时,收到以下消息:
Stackoverflow.com从您的Google帐户要求一些信息example@gmail.com
•电子邮件地址:example@gmail.com
但是,在我自己的站点上,当我使用OpenID登录时,我无法要求提供电子邮件地址。 相反,我收到此消息:
您正在使用Google帐户example@gmail.com登录example.com。
我还发现很难理解我需要在哪个步骤请求电子邮件地址。 这是我认为该步骤应内置的代码:
/**
* Authenticates the given OpenId identity.
* Defined by Zend_Auth_Adapter_Interface.
*
* @throws Zend_Auth_Adapter_Exception If answering the authentication query is impossible
* @return Zend_Auth_Result
*/
public function authenticate() {
$id = $this->_id;
$consumer = new Auth_OpenID_Consumer($this->_storage);
if (!empty($id)) {
$authRequest = $consumer->begin($id);
if (is_null($authRequest)) {
return new Zend_Auth_Result(
Zend_Auth_Result::FAILURE,
$id,
array("Authentication failed", 'Unknown error')
);
}
if (Auth_OpenID::isFailure($authRequest)) {
return new Zend_Auth_Result(
Zend_Auth_Result::FAILURE,
$id,
array("Authentication failed", "Could not redirect to server: " . $authRequest->message)
);
}
$redirectUrl = $authRequest->redirectUrl($this->_root, $this->_returnTo);
if (Auth_OpenID::isFailure($redirectUrl)) {
return new Zend_Auth_Result(
Zend_Auth_Result::FAILURE,
$id,
array("Authentication failed", $redirectUrl->message)
);
}
Zend_OpenId::redirect($redirectUrl);
} else {
$response = $consumer->complete(Zend_OpenId::selfUrl());
switch($response->status) {
case Auth_OpenID_CANCEL:
case Auth_OpenID_FAILURE:
return new Zend_Auth_Result(
Zend_Auth_Result::FAILURE,
null,
array("Authentication failed. " . @$response->message)
);
break;
case Auth_OpenID_SUCCESS:
return $this->_constructSuccessfulResult($response);
break;
}
}
}
看来应该是如此明显...但是我很难用Google搜寻并梳理代码以找出答案。 任何帮助将不胜感激!
您可以使用Zend Simple Registration Extension询问电子邮件地址
$sreg = new Zend_OpenId_Extension_Sreg(array(
'nickname'=>true,
'email'=>false,
'fullname'=>false), null, 1.1);
$consumer = new Zend_OpenId_Consumer();
if (!$consumer->login($_POST['openid_identifier'],
'example-6_3.php',
null,
$sreg)) {
die("OpenID login failed.");
}
如果要使用Janrain库,可以将扩展添加到请求中,如下所示:
$sreg_request = Auth_OpenID_SRegRequest::build(
// Required
array('nickname'),
// Optional
array('email'));
if ($sreg_request) {
$authRequest->addExtension($sreg_request);
}
看一下消费者示例: https : //github.com/openid/php-openid/blob/master/examples/consumer/
