使用OpenID的谷歌友好名称?

你不能。OP发布的标识符严格取决于OP。RP实际上没有任何发言权。现在,一些OPs支持在登录时提供属性,如昵称、电子邮件地址等。谷歌对这些属性的支持非常有限,只提供电子邮件地址。

谷歌选择不发布用户可识别标识符,因为这是一种信息泄露风险。雅虎通过向用户提供人性友好和非人性友好的标识符,用户可以在两者之间进行选择。MyOpenID和其他OP通常只使用用户在OP注册时选择的用户友好标识符。

必须仍然使用官方声明的标识符 从Google获取您传递给的用户的正式用户名 FormsAuthentication.RedirectFromLogin

基于Roy的回答,我尝试使用 DotNetOpenAuth 而且效果很好。

var req = openid.CreateRequest("https://www.google.com/accounts/o8/id");
var fetch = new FetchRequest();
fetch.Attributes.Add(new AttributeRequest(WellKnownAttributes.Contact.Email,true));
fetch.Attributes.Add(new AttributeRequest(WellKnownAttributes.Name.First,true));
fetch.Attributes.Add(new AttributeRequest(WellKnownAttributes.Name.Last,true));

req.AddExtension(fetch);

注意:确保第二个参数 AttributeRequest

响应部分是直截了当的。

var openid = new OpenIdRelyingParty();
var response = openid.GetResponse();
var fetch = response.GetExtension<FetchResponse>();
if (fetch != null) {
IList<string> emailAddresses =fetch.Attributes[WellKnownAttributes.Contact.Email].Values;
IList<string> firstNames = fetch.Attributes[WellKnownAttributes.Name.First].Values;
IList<string> lastName = fetch.Attributes[WellKnownAttributes.Name.Last].Values;
}
