You could include your own Register Service by using a copy of the RegisterService source code and modify it to suit your needs, e.g. Use a custom Register DTO with the additional properties you want.
But you can easily pass additional params without changing the existing Register DTO by adding it to the ?querystring which you can access inside your Services with:
var myParam = base.Request.QueryString["myParam"];
Otherwise the way to add your Custom Logic during registration or Authentication is to tap into the existing Session or Auth Events.
TechStacks has an example of this in its CustomAuthUserSession:
public class CustomUserSession : AuthUserSession
{
public string DefaultProfileUrl { get; set; }
public string GithubProfileUrl { get; set; }
public string TwitterProfileUrl { get; set; }
public override void OnAuthenticated(IServiceBase authService,
IAuthSession session,
IAuthTokens tokens,
Dictionary<string, string> authInfo)
{
base.OnAuthenticated(authService, session, tokens, authInfo);
var appSettings = authService.TryResolve<IAppSettings>();
var userAuthRepo = authService.TryResolve<IAuthRepository>();
var userAuth = userAuthRepo.GetUserAuth(session, tokens);
var dbConnectionFactory = authService.TryResolve<IDbConnectionFactory>();
foreach (var authTokens in session.ProviderOAuthAccess)
{
if (authTokens.Provider.ToLower() == "github")
{
GithubProfileUrl = session.GetProfileUrl();
}
if (authTokens.Provider.ToLower() == "twitter")
{
TwitterProfileUrl = session.GetProfileUrl();
if (appSettings.GetList("TwitterAdmins").Contains(session.UserName)
&& !session.HasRole(RoleNames.Admin))
{
userAuthRepo.AssignRoles(userAuth, roles:new[]{RoleNames.Admin});
}
}
DefaultProfileUrl = GithubProfileUrl ?? TwitterProfileUrl;
using (var db = dbConnectionFactory.OpenDbConnection())
{
var userAuthInstance = db.Single<CustomUserAuth>(x =>
x.Id == this.UserAuthId.ToInt());
if (userAuthInstance != null)
{
userAuthInstance.DefaultProfileUrl = this.DefaultProfileUrl;
db.Save(userAuthInstance);
}
}
}
}
}
Which fetches the Profile Url of the User when they login via GitHub or Twitter. Will assign the Admin role to users in the TwitterAdmins AppSetting, which is a way to assign admin rights to known Twitter users. Finally the retrieved Profile Url is added to the CustomUserAuth POCO Table and saved.
TechStacks tells ServiceStack to use its own CustomUserAuth table instead by registering a generic OrmLiteAuthRepository:
var authRepo = new OrmLiteAuthRepository<CustomUserAuth, UserAuthDetails>(dbFactory);
container.Register<IUserAuthRepository>(authRepo);
authRepo.InitSchema();
Where it will now Save User Information in the CustomUserAuth instead of the default UserAuth table.
