Question

i’m trying to set up my code to request some attributes from the OpenID Service Provider. At the same time, I wish to return an ActionResult.

Here’s the code in the OpenId sample MVC project (that comes straight out of the DotNetOpenId / DotNetOpenAuth website) …

try
{
    return openid.CreateRequest(Request.Form["openid_identifier"])
        .RedirectingResponse
        .AsActionResult();
 }
 catch (ProtocolException ex)
 { ... }

This is great, but it doesn’t show me requesting any optional or required attributes.
So, I’ve tried the following (my own, untested pseduo-ish code) ….

var fetch = new FetchRequest();
fetch.Attributes.AddRequired(WellKnownAttributes.Contact.Email);
fetch.Attributes.AddRequired(WellKnownAttributes.Name.FullName);
fetch.Attributes.AddRequired(WellKnownAttributes.Name.Alias);
fetch.Attributes.AddRequired(WellKnownAttributes.Preferences.Language);
fetch.Attributes.AddRequired(WellKnownAttributes.Preferences.TimeZone);
fetch.Attributes.AddRequired(WellKnownAttributes.Person.Gender);

openId.CreateRequest(identifier.ToString()).AddExtension(fetch);

This also seems fine. But … i don’t know how to now ask for the result to be an ActionResult()…

How can i create an openId.CreateRequest that allows me to define some required attributes AND return an ActionView ?

You’re doing great. Just combine the two approaches.

After you call IAuthenticationRequest.AddExtension all you want, just call IAuthenticationRequest.RedirectingResponse.AsActionResult().

try
{
    var request = openid.CreateRequest(Request.Form["openid_identifier"]);

    var fetch = new FetchRequest();
    fetch.Attributes.AddRequired(WellKnownAttributes.Contact.Email);
    fetch.Attributes.AddRequired(WellKnownAttributes.Name.FullName);
    fetch.Attributes.AddRequired(WellKnownAttributes.Name.Alias);
    fetch.Attributes.AddRequired(WellKnownAttributes.Preferences.Language);
    fetch.Attributes.AddRequired(WellKnownAttributes.Preferences.TimeZone);
    fetch.Attributes.AddRequired(WellKnownAttributes.Person.Gender);
    request.AddExtension(fetch);

    return request.RedirectingResponse.AsActionResult();
}
catch (ProtocolException ex)
{ ... }
