正如问题所说：）
这是我使用openid4java发出的请求：
DiscoveryInformation discovered = manager.associate(discoveries);
System.out.println("discovered");
// store the discovery information in the user's session
session.setAttribute("openid-disco", discovered);
// obtain a AuthRequest message to be sent to the OpenID provider
AuthRequest authReq = manager.authenticate(discovered, returnToUrl);
System.out.println("authReq Ok");
// Attribute Exchange example: fetching the 'email' attribute
FetchRequest fetch = FetchRequest.createFetchRequest();
System.out.println("fetch");
fetch.addAttribute("gender", // attribute alias
"http://schema.openid.net/gender", // type URI
true);
fetch.addAttribute("email",
"http://schema.openid.net/contact/email",
true);
fetch.addAttribute("first",
"namePerson/first",
true);
// attach the extension to the authentication request
authReq.addExtension(fetch);
这是我收到的回复。如您所知，名字和性别统计数字为0：

我尝试myopenid和gmail作为提供商，但它只发送电子邮件。在我的页面重定向时，从提供者页面，它只显示电子邮件，这是我在代码中所要求的一件事，但我添加了名称和性别。
我想获取除姓名，性别和DOB等电子邮件之外的其他信息。
Upadte：我使用了sreg扩展对象，我有三个值（名称，电子邮件，昵称） 但是仍然希望能够获得其他值，如地址......
