openid:尝试从google op获取电子邮件地址

好的,明白了。我在上发布了一个问题 Goolge's Federated Log API group 并被告知使用 Attribute exchange .

下面是代码 DotNetOpenAuth .

请不要在生产中使用此代码。这仅用于说明!

请求:

using (OpenIdRelyingParty openid = new OpenIdRelyingParty())
{
    IAuthenticationRequest request = openid.CreateRequest(openidurl);

    var fetch = new FetchRequest();
    fetch.Attributes.AddRequired(WellKnownAttributes.Contact.Email);
    request.AddExtension(fetch);

    // Send your visitor to their Provider for authentication.
    request.RedirectToProvider();
}

回答:

OpenIdRelyingParty openid = new OpenIdRelyingParty();
var response = openid.GetResponse();
if (response != null)
{
    switch (response.Status)
    {
        case AuthenticationStatus.Authenticated:
        {
            var fetch = response.GetExtension<FetchResponse>();
            string email = string.Empty();
            if (fetch != null)
            {
                email =  fetch.GetAttributeValue(
                    WellKnownAttributes.Contact.Email);
            }

            FormsAuthentication.RedirectFromLoginPage(
                response.ClaimedIdentifier, false);
            break;
        }
        ...
    }
}

当我尝试获取全名时,响应为空,请提供获取全名的解决方案, 这篇文章真的很有帮助 谢谢。 我的示例代码是这样的。

var fetch = new FetchRequest();
            fetch.Attributes.AddRequired(WellKnownAttributes.Contact.Email);
            fetch.Attributes.AddRequired(WellKnownAttributes.Name.FullName);
            fetch.Attributes.AddRequired(WellKnownAttributes.Company.CompanyName);
            //fetch.Attributes.AddRequired(WellKnownAttributes.Contact.Email);

            request.AddExtension(fetch);

和

if (fetch != null)
         {
             email = fetch.GetAttributeValue(WellKnownAttributes.Contact.Email);
             name = fetch.GetAttributeValue(WellKnownAttributes.Name.FullName);
             company = fetch.GetAttributeValue(WellKnownAttributes.Company.CompanyName);
         }
