I validate token using middle ware in case of access token not valid return message not valid and this case work perfect
problem come when valid token success the problem is next request no give me result of action executed so that what i do for that working
problem is when success valid token is OK it reach until next but not display after that action that have result
and only return invalid token message i write on middle ware in both cases of valid or not valid access token
when i test it by post man it working good
if token is not valid
return invalid token
else
return user menu data in case of make request to get data for menu as example
my code as below :
public async Task InvokeAsync(HttpContext context, DataContext dataContext)
{
var validKey = false;
// than you logic to validate token
var CheckExistAccessToken = context.Request.Headers.ContainsKey("Authorization");
var AccessTokenValue = context.Request.Headers["Authorization"].SingleOrDefault();
//var token = AccessTokenValue.Substring(AccessTokenValue.IndexOf(' ') + 1);
if (CheckExistAccessToken)
{
bool isvalid = _tockenvalidator.ValidateToken(AccessTokenValue);
if (isvalid)
{
validKey = true;
}
else
{
validKey = false;
}
}
if (!validKey)
{
context.Response.StatusCode = (int)HttpStatusCode.Forbidden;
await context.Response.WriteAsync("Invalid Token");
}
//if valid than next middleware Invoke
else
{
await _next.Invoke(context);
}
}
}
public static class TokenExtensions
{
public static IApplicationBuilder UseTokenAuth(this IApplicationBuilder builder)
{
return builder.UseMiddleware<TokenValidateMiddleware>();
}
}
on configure of startup.cs
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
// The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
app.UseHsts();
}
app.UseTokenAuth();
app.UseHttpsRedirection();
app.UseStatusCodePagesWithReExecute("/error/{0}");
app.UseMvc();
app.UseCors("CorsData");
app.UseStaticFiles();
app.UseDefaultFiles();
when success token by debug
i reach to this line await _next.Invoke(context);
but not give me result as action i write on post man
suppose when access token valid return data for user menu
this working on post man but on my app return invalid token why
If I understand correctly, the custom middleware functions as expected when submitting a bearer token using PostMan as the client. The custom middleware does not function as expected when testing using another client.
Can you explain or share the client code? Specifically, how does the client pass the bearer token?
As I understand, testing with PostMan works but your client application does not. Your follow up post confirms PostMan functions as expected?
Can you explain how your custom token validation code is intended to function? Keep in mind, you approach is non standard and not recommended. As I recommended in your similar post, you should use the standard API library that comes with the framework.
The API along with [Authorize] will return a standard 401 (Unauthorized) HTTP response.
public interface ItockenValidate
{
bool ValidateToken(string AccessTokenValue);
}
public class tockenValidate : ItockenValidate
{
public bool ValidateToken(string AccessTokenValue)
{
try
{
var tokenHandler = new JwtSecurityTokenHandler();
var validationParameters = GetValidationParameters();
SecurityToken validatedToken;
IPrincipal principal = tokenHandler.ValidateToken(AccessTokenValue, validationParameters, out validatedToken);
return true;
}
catch (Exception)
{
return false;
}
}
TokenValidationParameters GetValidationParameters()
{
return new TokenValidationParameters()
{
ValidateLifetime = false, // Because there is no expiration in the generated token
ValidateAudience = false, // Because there is no audiance in the generated token
ValidateIssuer = false, // Because there is no issuer in the generated token
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("401b09eab3c013d4ca54922bb802bec8fd5318192b0a75f201d8b3727429090fb337591abd3e44453b954555b7a0812e1081c39b740293f765eae731f5a65ed1")) // The same key as the one that generate the token
//pay = ((JwtSecurityToken)access_token).Payload["userId"].ToString()
};
}
