我有一些代码应该重定向到OpenId的Google登录页面
<?php
include '../connect.php';
require_once "common.php";
$path = $_GET['path'];
if (empty( $path ) )
{
$error = "Expected an OpenID URL.";
//include 'index.php';
//exit(0);
}
else
{
echo "<p>Success, path: ".$path."</p>";
}
$consumer = getConsumer();
// Begin the OpenID authentication process.
$auth_request = $consumer->begin($path);
// No auth request means we can't begin OpenID.
if (!$auth_request)
{
echo "<p>Authentication error; not a valid OpenID.</p>";
}
$sreg_request = Auth_OpenID_SRegRequest::build(
// Required
array('nickname'),
// Optional
array('fullname', 'email'));
if ($sreg_request)
{
$auth_request->addExtension($sreg_request);
}
$policy_uris = $_GET['policies'];
$pape_request = new Auth_OpenID_PAPE_Request($policy_uris);
if ($pape_request)
{
$auth_request->addExtension($pape_request);
}
// Redirect the user to the OpenID server for authentication.
// Store the token for this authentication so we can verify the response.
// For OpenID 1, send a redirect. For OpenID 2, use a Javascript
// form to send a POST request to the server.
if ($auth_request->shouldSendRedirect())
{
$redirect_url = $auth_request->redirectURL(getTrustRoot(), getReturnTo());
// If the redirect URL can't be built, display an error
// message.
if (Auth_OpenID::isFailure($redirect_url))
{
displayError("Could not redirect to server: " . $redirect_url->message);
}
else
{
// Send redirect.
echo '<p>Would have redirected url</p>';
header("Location: ".$redirect_url);
}
}
else
{
// Generate form markup and render it.
$form_id = 'openid_message';
$form_html = $auth_request->htmlMarkup(getTrustRoot(), getReturnTo(),
false, array('id' => $form_id));
// Display an error if the form markup couldn't be generated;
// otherwise, render the HTML.
if (Auth_OpenID::isFailure($form_html))
{
echo "<p>Could not redirect to server: " . $form_html->message."</p>";
}
else
{
print $form_html;
}
}
run ();
?>
然后页面应该返回到一个名为finish_auth.php的脚本（此处有很多调试语句）：
<?php
require_once "common.php";
session_start();
function escape($thing)
{
return htmlentities($thing);
}
function run()
{
$consumer = getConsumer();
var_dump($consumer);
echo '<p>test 2</p>';
// Complete the authentication process using the server's
// response.
$return_to = getReturnTo();
var_dump($return_to);
echo '<p>test 3</p>';
$response = $consumer->complete($return_to);
var_dump($response);
echo '<p>test 4</p>';
// Check the response status.
if ($response->status == Auth_OpenID_CANCEL)
{
// This means the authentication was cancelled.
$msg = 'Verification canceled.';
echo '<p>Canceled</p>';
}
else
if ($response->status == Auth_OpenID_FAILURE)
{
echo '<p>Open Id Failure</p>';
// Authentication failed; display the error message.
$msg = "OpenID authentication failed: " . $response->message;
}
else
if ($response->status == Auth_OpenID_SUCCESS)
{
echo '<p>SUCCESS</p>';
// This means the authentication succeeded; extract the
// identity URL and Simple Registration data (if it was
// returned).
$openid = $response->getDisplayIdentifier();
var_dump($openid);
$esc_identity = escape($openid);
$success = sprintf('You have successfully verified ' .
'<a href="%s">%s</a> as your identity.',
$esc_identity, $esc_identity);
if ($response->endpoint->canonicalID)
{
$escaped_canonicalID = escape($response->endpoint->canonicalID);
$success .= ' (XRI CanonicalID: '.$escaped_canonicalID.') ';
}
$sreg_resp = Auth_OpenID_SRegResponse::fromSuccessResponse($response);
$sreg = $sreg_resp->contents();
var_dump($sreg);
echo '<p>test sreg</p>';
if (@$sreg['email'])
{
$success .= " You also returned '".escape($sreg['email']).
"' as your email.";
echo $success;
}
else
{
echo '<p>Not email success</p>';
}
if (@$sreg['nickname'])
{
$success .= " Your nickname is '".escape($sreg['nickname']).
"'.";
echo $success;
}
else
{
echo '<p>Not nickname success</p>';
}
if (@$sreg['fullname'])
{
$success .= " Your fullname is '".escape($sreg['fullname']).
"'.";
echo $success;
}
else
{
echo '<p>Not full name success</p>';
}
$pape_resp = Auth_OpenID_PAPE_Response::fromSuccessResponse($response);
if ($pape_resp)
{
if ($pape_resp->auth_policies)
{
$success .= "<p>The following PAPE policies affected the authentication:</p><ul>";
foreach ($pape_resp->auth_policies as $uri)
{
$escaped_uri = escape($uri);
$success .= "<li><tt>$escaped_uri</tt></li>";
}
$success .= "</ul>";
}
else
{
$success .= "<p>No PAPE policies affected the authentication.</p>";
}
if ($pape_resp->auth_age)
{
$age = escape($pape_resp->auth_age);
$success .= "<p>The authentication age returned by the " .
"server is: <tt>".$age."</tt></p>";
}
if ($pape_resp->nist_auth_level)
{
$auth_level = escape($pape_resp->nist_auth_level);
$success .= "<p>The NIST auth level returned by the " .
"server is: <tt>".$auth_level."</tt></p>";
}
}
else
{
$success .= "<p>No PAPE response was sent by the provider.</p>";
}
}
//include '../index.php';
// header( 'Location: http://www.comehike.com' );
// $_SESSION['user_id'] = $user_id;
// $_SESSION['user_email'] = $row['user_email'];
// $_SESSION['user_lat'] = $row['lat'];
// $_SESSION['user_lng'] = $row['lng'];
// $_SESSION['first_name'] = $row['first_name'];
}
run();
?>

我想知道的是 - 如何让页面实际重定向到谷歌页面进行登录？当前的ux不会带您到那里验证您可以使用您的Gmail帐户登录到comehike.com
谢谢！
