@Sreeram Jayaram This error occurs because the SecurityTokenDescriptor
class is defined in both Microsoft.IdentityModel.Tokens
and Microsoft.IdentityModel
namespaces. To resolve this error, you can use the fully qualified name of the SecurityTokenDescriptor
class in your code.
Replace the line var tokenDescriptor = new Microsoft.IdentityModel.Tokens.SecurityTokenDescriptor
with var tokenDescriptor = new System.IdentityModel.Tokens.Jwt.SecurityTokenDescriptor
.
This will use the SecurityTokenDescriptor
class from the System.IdentityModel.Tokens.Jwt
namespace instead of the Microsoft.IdentityModel.Tokens
namespace.
Here's the updated code:
public string GenerateClientAccessToken(string hubName, string userId = null, IList claims = null, TimeSpan? lifeTime = null)
{
var tokenLifetime = lifeTime ?? TimeSpan.FromHours(1); // Default lifetime is one hour
var claimsIdentity = new ClaimsIdentity(claims ?? Array.Empty());
if (!string.IsNullOrEmpty(userId))
{
claimsIdentity.AddClaim(new Claim(ClaimTypes.NameIdentifier, userId));
}
var tokenHandler = new JwtSecurityTokenHandler();
var tokenDescriptor = new System.IdentityModel.Tokens.Jwt.SecurityTokenDescriptor
{
Expires = DateTime.UtcNow.Add(tokenLifetime),
SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(Guid.NewGuid().ToByteArray()), SecurityAlgorithms.HmacSha256),
Subject = claimsIdentity,
};
var token = tokenHandler.CreateToken(tokenDescriptor);
return tokenHandler.WriteToken(token);
}
