我正在尝试研究class.openid.php，因为它比
lightopenid更简单，更小。为了我的目的200线是重要的。但是class.openid.php无法与google openID https://www.google.com/accounts/o8/id一起使用，打印给我这样的错误：
ERROR CODE: OPENID_NOSERVERSFOUND
ERROR DESCRIPTION: Cannot find OpenID Server TAG on Identity page.
是否可以让class.openid.php（任何版本）与google openID一起使用以及如何做这样的事情？
class.openid.php可以here，但它对我来说不起作用，所以我必须找到所有<?并用<?php替换tham以防万一我希望看到我得到的代码：
html界面页面：
<?php
require('class.openid.v3.php');
if ($_POST['openid_action'] == "login"){ // Get identity from user and redirect browser to OpenID Server
$openid = new SimpleOpenID;
$openid->SetIdentity($_POST['openid_url']);
$openid->SetTrustRoot('http://' . $_SERVER["HTTP_HOST"]);
$openid->SetRequiredFields(array('email','fullname'));
$openid->SetOptionalFields(array('dob','gender','postcode','country','language','timezone'));
if ($openid->GetOpenIDServer()){
$openid->SetApprovedURL('http://' . $_SERVER["HTTP_HOST"] . $_SERVER["PATH_INFO"]); // Send Response from OpenID server to this script
$openid->Redirect(); // This will redirect user to OpenID Server
}else{
$error = $openid->GetError();

问题在于Google不仅提供OpenID端点。
OpenId端点包含用户的标识符。
我们在这里所称的是发现网址。
这是一个静态网址，您可以将任何用户定向到该网址，服务本身会识别该用户并返回每个用户唯一的识别网址。
然而 大多数 openid客户端库无法正确实现，包括官方openid网站上的大多数链接。
即使是Zend Framework库也无法处理它。
然而，我找到了一个从不同角度分析的课程，我非常满意。在我工作的公司，我们已经成功地将它集成到几个生产环境中，并且没有遇到任何问题。
您可能还对我的另一篇文章感兴趣，该文章涉及将Facebook变为开放式提供商的问题。我正在使用的课程也支持Google，也可以在那里找到：

有一个PHP部分。
答案 2 :(得分：2)
您问题中的类根本不支持OpenID 2.0。因此，如果不添加大量代码，它将无法与Google配合使用。
