  How to get simple username in Google login to my ASP.Net Site

  Jun 28, 2017 05:19 AM|hkbeer|LINK

  I have created a standard ASP.Net site using VS2017 template and add external login using Google and Microsoft.
  
  It was a success. When users first login this way, they will be asked to key in an Alias.
  Eg a user may enter "Superman" and in their next log in their Alias is displayed on the menu bar.

  I found the log file in App_Data is logging using their alias (eg superman) which is totally useless for me for identity purpose.

  I need to get their email account name instead as "superman" does not enable me to identify the person.
  (eg if it is SteveJob@gmail.com then I simply need SteveJob or simply his email.)

  Some people gave me this code below to pull their login into label1.text, it works but it is getting their Alias again only.

  Is there way to get their username instead. I do not intend to get their profile, just username of email will do.

  What I am trying now is I changed "Name" in the code below to something else, and as I type a dot VS intellisense gives me a lot of choices such as Email, First Name, Gender etc. so it seems this is possible.

  But on-run, all these 3 returns a blank value. Seems we are not able to get anything from Google/Microsoft.

  Please anyone inform me what is still missing ? I do not need his profile details, just simple username is sufficient.

  Thanks a lot.

  var identity = (ClaimsIdentity)HttpContext.Current.User.Identity;
          var name = identity.Claims.FirstOrDefault(m => m.Type == System.Security.Claims.ClaimTypes.Name).Value;

  Thanks. I will try to credit the ones who helped but most important is we really do sincerely thanks to all who have helped.

  Hi  hkbeer

  Try to using the following code:

    var loginInfo = AuthenticationManager.GetExternalLoginInfoAsync();
    var name=loginInfo.Email;
  

  For more information, please refer to the following links:

  Hi hkbeer,

  If you have an existing project that doesn’t have any identity features installed you’ll need to get the right assemblies into your project. 

  Luckily, thanks to the power of NuGet, to get just the core identity features you can add just the following packages to get all the references you needed for the core identity features plus a few of the external providers needed.

  • Microsoft.Owin.Host.SystemWeb
  • Microsoft.Owin.Security.Cookies

  The first two packages are enough to light up the OWIN identity framework. 

  You’ll also need to install the the specific external provider packages:

  • Microsoft.Owin.Security.Google
  • Microsoft.Owin.Security.Twitter
  • Owin.Security.Providers

  The provider packages add support for specific external providers you can log in with.
