Question

I have a site which is using facebook for auth. I want to gather some basic info when a user signs up including their email address.

The code i have for the login is standard:

public ActionResult Login(string returnUrl)
    {
        var oAuthClient = new FacebookOAuthClient();
        oAuthClient.AppId = AppSettings.GetConfigurationString("appId");
        oAuthClient.RedirectUri = new Uri(AppSettings.GetConfigurationString("redirectUrl"));
        var loginUri = oAuthClient.GetLoginUrl(new Dictionary<string, object> { { "state", returnUrl } });
        return Redirect(loginUri.AbsoluteUri);
    }

How do i add the request to access permissions in that? Or do i do it another way?

A snoop at the sdk code and i came up wiht:

 public ActionResult Login(string returnUrl)
    {
        var oAuthClient = new FacebookOAuthClient();
        oAuthClient.AppId = AppSettings.GetConfigurationString("appId");
        oAuthClient.RedirectUri = new Uri(AppSettings.GetConfigurationString("redirectUrl"));

        var parameters = new Dictionary<string, object>();
        parameters["state"] = returnUrl;
        parameters["scope"] = "email";

        var loginUri = oAuthClient.GetLoginUrl(parameters);
        return Redirect(loginUri.AbsoluteUri);
    }

not tested it yet and the missus is shouting at me for working late so will have to test tomoz 🙂
