I have the following code:
protected void Page_Load(object sender, EventArgs e)
{
var openId = new OpenIdRelyingParty();
HttpContext httpContext = HttpContext.Current;
var headers = new WebHeaderCollection();
foreach (string header in httpContext.Request.Headers)
{
headers.Add(header, httpContext.Request.Headers[header]);
}
string requestUrl = string.Format("http://localhost:12345/Login/{0}",
httpContext.Request.Url.Query);
var requestInfo = new HttpRequestInfo(httpContext.Request.HttpMethod,
new Uri(requestUrl),
httpContext.Request.RawUrl, headers,
httpContext.Request.InputStream);
var response = openId.GetResponse(requestInfo);
if (response != null)
{
ClaimsResponse claimResponse = response.GetExtension<ClaimsResponse>();
lblUser.Text = claimResponse.FullName;
if (response.Exception != null)
{
lblError.Text = response.Exception.Message;
}
}
}
protected void btnTest_Click(object sender, EventArgs e)
{
try
{
using (OpenIdRelyingParty openId = new OpenIdRelyingParty())
{
string identifier = #"https://www.google.com/accounts/o8/id";
var request = openId.CreateRequest(identifier,
new Realm("http://localhost:12345/"),
new Uri("http://localhost:12345/Login/"));
request.AddExtension(new ClaimsRequest
{
Email = DemandLevel.Require
});
request.RedirectToProvider();
}
}
catch (Exception ex)
{
// TODO: log exception
throw;
}
}
When I execute the code, user is authenticated but ClaimsResponse is null.
Code works fine with MyOpenId.
Any help would be appreciated.
The information here is useful: Retrieve OpenId User Information (Claims) across providers
The gold nugget you are likely missing in your app is the AXFetchAsSregTransform.

The issue might be caused by the HostName been blocked because of Area Policy .
You could solve this by modifying the DNS (to 8.8.8.8 as an example) for your Mac as well.
Your device, Settings/Wi-Fi
Choose connected Wi-Fi pot
Press DHCP/DNS
Set to 8.8.8.8
Or you could connect phone to the VPN for your apps deployed to device to see corporate servers.

I'm trying to implement a Google OpenID login
I have the following questions:
Where can I get the value of the variable openidurl in the line
IAuthenticationRequest request = openid.CreateRequest(openidurl);
2.. How can I restrict the login for a certain Google Apps Domain only?
The code is the following:
protected void Page_Load(object sender, EventArgs e)
{
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);
Session["email"] = email;
Response.Redirect("profile.aspx");
break;
}
}
}
protected void OpenLogin_Click(object src, CommandEventArgs e)
{
string openidurl = "https://www.google.com/accounts/o8/id?id=initial_id"; //auxiliary initial id. ??????
//The Request
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();
}
}
}
Thanks in advance, this is the first time I use Google OpenIDs.
hello i have a following code in asp.net. i have used DotNetOpenAuth.dll for openID. the code is under
protected void openidValidator_ServerValidate(object source, ServerValidateEventArgs args)
{
// This catches common typos that result in an invalid OpenID Identifier.
args.IsValid = Identifier.IsValid(args.Value);
}
protected void loginButton_Click(object sender, EventArgs e)
{
if (!this.Page.IsValid)
{
return; // don't login if custom validation failed.
}
try
{
using (OpenIdRelyingParty openid = this.createRelyingParty())
{
IAuthenticationRequest request = openid.CreateRequest(this.openIdBox.Text);
// This is where you would add any OpenID extensions you wanted
// to include in the authentication request.
ClaimsRequest objClmRequest = new ClaimsRequest();
objClmRequest.Email = DemandLevel.Request;
objClmRequest.Country = DemandLevel.Request;
request.AddExtension(objClmRequest);
// Send your visitor to their Provider for authentication.
request.RedirectToProvider();
}
}

this.openidValidator.IsValid = false;
}

// Store off the "friendly" username to display -- NOT for username lookup
State.FriendlyLoginName = response.FriendlyIdentifierForDisplay;

case 2: openid.SecuritySettings.MinimumRequiredOpenIdVersion = ProtocolVersion.V20; break;
default: throw new ArgumentOutOfRangeException("minversion");
}
}
return openid;
}
for above code i am always getting
var claimsResponse = response.GetExtension<ClaimsResponse>();
i am always getting claimsResponse= null. what is the reason why it happen. is there any requirement which is required for openid like domain validation for RelyingParty?? please give me answer as soon as possible.
