我尝试使用带有 OpenID4Java 库的 Google Apps 开放 ID 登录。
我在消费者类中使用以下代码发现用户的服务:
try
{
discoveries = consumerManager.discover(identityUrl);
}
catch (DiscoveryException e)
{
throw new OpenIDConsumerException("Error during discovery", e);
}
DiscoveryInformation information = consumerManager.associate(discoveries);
HttpSession session = req.getSession(true);
session.setAttribute(DiscoveryInformation.class.getName(), information);
AuthRequest authReq;
try
{
authReq = consumerManager.authenticate(information, returnToUrl, realm);
// check for OpenID Simple Registration request needed
if (attributesByProvider != null || defaultAttributes != null)
{
//I set the attributes needed for getting the email of the user
}
}
catch (Exception e)
{
throw new OpenIDConsumerException("Error processing ConumerManager authentication", e);
}
return authReq.getDestinationUrl(true);
接下来,我从 http 请求中获取参数,并在 openid.claimed_id 属性中收到“ http://domain.com/openid?id= ....”,如果我尝试验证响应consumerManager.verify(receivingURL.toString(), openidResp, discovered);
,则会引发异常:。org.openid4java.discovery.yadis.YadisException: 0x706: GET failed on http://domain.com/openid?id=... : 404:Not Found
为避免异常,我尝试修改参数列表,将值“ http://domain.com/openid?id= ....”更改为“ https://www.google.com/a/domain.com/ openid?id= ....”
// extract the receiving URL from the HTTP request
StringBuffer receivingURL = request.getRequestURL();
String queryString = request.getQueryString();
// extract the parameters from the authentication response
// (which comes in as a HTTP request from the OpenID provider)
ParameterList openidResp = new ParameterList(request.getParameterMap());
Parameter endPoint = openidResp.getParameter("openid.op_endpoint");
if (endPoint != null && endPoint.getValue().startsWith("https://www.google.com/a/"))
{
Parameter parameter = openidResp.getParameter("openid.claimed_id");
if (parameter != null)
{
String value = "https://www.google.com/a/" + parameter.getValue().replaceAll("http://", "");
openidResp.set(new Parameter("openid.claimed_id", value));
queryString = queryString.replaceAll("openid.claimed_id=http%3A%2F%2F", "openid.claimed_id=https%3A%2F%2Fwww.google.com%2Fa%2F");
}
parameter = openidResp.getParameter("openid.identity");
if (parameter != null)
{
String value = "https://www.google.com/a/" + parameter.getValue().replaceAll("http://", "");
openidResp.set(new Parameter("openid.identity", value));
queryString = queryString.replaceAll("openid.claimed_id=http%3A%2F%2F", "openid.claimed_id=https%3A%2F%2Fwww.google.com%2Fa%2F");
}
}
if ((queryString != null) && (queryString.length() > 0))
{
receivingURL.append("?").append(queryString);
}
// retrieve the previously stored discovery information
DiscoveryInformation discovered = (DiscoveryInformation) request.getSession().getAttribute(DiscoveryInformation.class.getName());
// verify the response
VerificationResult verification;
Map userDetails = new HashMap();
try
{
verification = consumerManager.verify(receivingURL.toString(), openidResp, discovered);
// check for OpenID Simple Registration request needed
if (attributesByProvider != null || defaultAttributes != null)
{
//Here I get the value of requested attributes
}
}
catch (Exception e)
{
throw new OpenIDConsumerException("Error verifying openid response", e);
}
// examine the verification result and extract the verified identifier
Identifier verified = null;
if (verification != null)
{
verified = verification.getVerifiedId();
}
OpenIDAuthenticationToken returnToken;
List attributes = null;
if (verified != null)
returnToken = new OpenIDAuthenticationToken(OpenIDAuthenticationStatus.SUCCESS, verified.getIdentifier(), "some message", attributes);
else
{
Identifier id = discovered.getClaimedIdentifier();
return new OpenIDAuthenticationToken(OpenIDAuthenticationStatus.FAILURE, id == null ? "Unknown" : id.getIdentifier(), "Verification status message: [" + verification.getStatusMsg() + "]", attributes);
}
现在该方法consumerManager.verify
不再抛出异常,但其状态更改为失败。在日志中出现以下错误
09:46:45,424 ERROR ConsumerManager,http-80-1:1759 - No service element found to match the ClaimedID / OP-endpoint in the assertion.
09:46:45,428 ERROR ConsumerManager,http-80-1:1183 - Discovered information verification failed.
我在论坛上看到类似的问题,但解决方案是更改consumerManager.verify
为consumerManager.verifyNonce
. 我不确定使用这种方法是否会产生安全问题。你知道我应该改变什么来让我的 open id 消费者与 Google Apps openid 一起工作吗?
