How to Query Database From Startup.CS - asp.net-core-3.1

Question

I am doing user authentication in my startup.cs. I need to query my database using the OpenIDConnect claims info. This is what I have done but don't know how to get the connection to work. I tried injecting the db query constructor at the top of the startup.cs like this and then calling the query as follows:
public class Startup
{
protected IAdoSqlService _adoSqlService;
public Startup(IConfiguration configuration, IAdoSqlService adoSqlService)
{
Configuration = configuration;
_adoSqlService = adoSqlService;
}
public void ConfigureServices(IServiceCollection services)
{
// do ConfigureServices stuff
options.Events = new OpenIdConnectEvents()
{
OnTokenValidated = async ctx =>
{
// This is the ClaimsIdentity created by OpenID Connect, you can add claims to it directly
ClaimsIdentity claimsIdentity = ctx.Principal.Identities.FirstOrDefault();
string userntid = claimsIdentity.Claims.FirstOrDefault(c => c.Type == "preferred_username").Value;
//How do I call the database to run the following query
int isUser = _adoSqlService.isUser(userntid);
if (isUser > 0)
{
claimsIdentity.AddClaim(new Claim(ClaimTypes.Role, "user"));
}
else
{
claimsIdentity.AddClaim(new Claim(ClaimTypes.Role, "not authorized"));
}
}
}
//More stuff
}
}
When I run the above, it errors in program.cs before even running with the following error
System.InvalidOperationException: 'Unable to resolve service for type 'XXXX.Services.IAdoSqlService' while attempting to activate 'XXXX.Startup'.'
So how do I make the call _adoSqlService.isUser(userntid); to the database?
I am NOT using EF.
Solution
I figured this out by doing the following:
I moved most of my services to the top of the ConfigureServices section (based on something that #qudus said) before I performed my authentication.
I removed the database injection code from the top of the startup.cs.
Lastly I changed the OnTokenValidated to use the following:
ctx.HttpContext.RequestServices.GetRequiredService();
Here is the code:
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
internal static IConfiguration Configuration { get; private set; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
var connectionSection = Configuration.GetSection("ConnectionStrings");
services.Configure<ConnectionStrings>(connectionSection);
services.AddScoped<IAdoSqlService, AdoSqlService>();
services.AddControllersWithViews();
services.AddHttpContextAccessor();
services.AddSingleton<IActionContextAccessor, ActionContextAccessor>();
services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
services.AddSession();
// Load the Federation configuration section from app settings
var federationConfig = Configuration.GetSection("Federation");
services.Configure<CookiePolicyOptions>(options =>
{
options.MinimumSameSitePolicy = SameSiteMode.None;
});
services.AddAuthentication(sharedOptions =>
{
sharedOptions.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
sharedOptions.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
})
.AddCookie(options =>
{
options.ExpireTimeSpan = TimeSpan.FromHours(2);//default is 14days
options.SlidingExpiration = true;// default
options.AccessDeniedPath = "/Error/AuthenticateError";// set a custom error access denied error page. this would need to be created/handled in your app.
})
.AddOpenIdConnect(options =>
{
//Set Options here......
//optional customizations to the auth and failure events
options.Events = new OpenIdConnectEvents()
{
OnRedirectToIdentityProvider = context =>
{
return Task.CompletedTask;
},
OnRemoteFailure = context =>
{
// handle an error response from Federation and redirect the user to a custom error page instead
context.Response.Redirect("/Error/401");
context.HandleResponse();
return Task.CompletedTask;
},
OnTokenValidated = async ctx =>
{
// This is the ClaimsIdentity created by OpenID Connect, you can add claims to it directly
ClaimsIdentity claimsIdentity = ctx.Principal.Identities.FirstOrDefault();
string userntid = claimsIdentity.Claims.FirstOrDefault(c => c.Type == "preferred_username").Value;
string username = claimsIdentity.Claims.FirstOrDefault(c => c.Type == "name").Value;
int isUser = 0;
int isAdmin = 0;
try
{
var db = ctx.HttpContext.RequestServices.GetRequiredService<IAdoSqlService>();
isUser = db.isUser(userntid);
isAdmin = db.isAdmin(userntid);
}
catch (Exception ex)
{
string error = ex.Message;
}
AppHttpContext.Current.Session.SetString("IsUser", "false");
if (isUser > 0)
{
claimsIdentity.AddClaim(new Claim(ClaimTypes.Role, "user"));
AppHttpContext.Current.Session.SetString("IsUser", "true");
}
AppHttpContext.Current.Session.SetString("IsUserAdmin", "false");
if (isAdmin > 0)
{
claimsIdentity.AddClaim(new Claim(ClaimTypes.Role, "admin"));
AppHttpContext.Current.Session.SetString("IsUserAdmin", "true");
}
if (isUser == 0 && isAdmin == 0)
{
claimsIdentity.AddClaim(new Claim(ClaimTypes.Role, "not authorized"));
}
}
};
});
