Thank you Peter for idea.
If smb need to create JWT token authorization for old ASP.NET MVC5.I wrote small example. I don't serialize cookie to JWT. I create a JWT and after I am checking it in the BeginRequest. If everything is ok, I create a cookie and set it to the httpContext.Request. I used authentication mode="Forms" for application and it require cookies.
For create JWT token:
const string secret = "GQDstcKsx0NHjPOuXOYg5MbeJ1XT0uFiwDVvVBrk";
[AllowAnonymous]
[HttpPost]
public ActionResult LoginJWT(LoginViewModel model)
{
ActionResult response = null;
if (ModelState.IsValid)
{
if (true) //todo: check user login&password
{
var payload = new Dictionary<string, object>
{
{ "iss", "subject" },
{ "sub", "api" },
{ "exp", DateTimeOffset.UtcNow.AddHours(2).ToUnixTimeSeconds()},
{ "iat", DateTimeOffset.UtcNow.ToUnixTimeSeconds()},
{ "jti", Guid.NewGuid() },
{ "uid", "64" } //custom field for identificate user
};
IJwtAlgorithm algorithm = new HMACSHA256Algorithm(); // symmetric
IJsonSerializer serializer = new JsonNetSerializer();
IBase64UrlEncoder urlEncoder = new JwtBase64UrlEncoder();
IJwtEncoder encoder = new JwtEncoder(algorithm, serializer, urlEncoder);
var token = encoder.Encode(payload, secret);
response = Content(token);
}
else
{
response = new HttpStatusCodeResult(System.Net.HttpStatusCode.BadRequest, "Login or password are not found");
}
}
else
{
response = new HttpStatusCodeResult(System.Net.HttpStatusCode.BadRequest, "Errors in Model");
}
return response;
}
For check JWT token in Global.asax:
public override void Init()
{
this.BeginRequest += this.BeginRequestHandler;
base.Init();
}
private void BeginRequestHandler(object sender, EventArgs e)
{
var bearerToken = this.Context.Request.Headers["Authorization"];
if (bearerToken != null)
{
var token = bearerToken.StartsWith("Bearer ") ? bearerToken.Substring(7) : bearerToken;
const string secret = "GQDstcKsx0NHjPOuXOYg5MbeJ1XT0uFiwDVvVBrk";
int userId = 0;
try
{
IJsonSerializer serializer = new JsonNetSerializer();
var provider = new UtcDateTimeProvider();
IJwtValidator validator = new JwtValidator(serializer, provider);
IBase64UrlEncoder urlEncoder = new JwtBase64UrlEncoder();
IJwtAlgorithm algorithm = new HMACSHA256Algorithm(); // symmetric
IJwtDecoder decoder = new JwtDecoder(serializer, validator, urlEncoder, algorithm);
var json = decoder.DecodeToObject<IDictionary<string, string>>(token, secret, verify: true);
if (json.TryGetValue("uid", out var uid))
{
userId = Convert.ToInt32(uid);
}
}
catch (TokenExpiredException)
{
Console.WriteLine("Token has expired");
}
catch (SignatureVerificationException)
{
Console.WriteLine("Token has invalid signature");
}
if (userId != 0)
{
// check user by id, if found create cookie.
}
}
}
I used:
jwt-dotnet/jwt library 7.2.1
