JWT Token validation

JWT Token validation

I am trying to perform JWT validation for each action excepting the LogIn and Register actions, but I cannot find a way to do it in action filters, as i need the token and it's on this.Request.Headers. This is the validation method which works fine:

I am trying to perform JWT validation for each action excepting the LogIn and Register actions, but I cannot find a way to do it in action filters, as i need the token and it's on this.Request.Headers. This is the validation method which works fine:

try
{
    JwtSecurityTokenHandler tokenHandler = new JwtSecurityTokenHandler();
    string sToken = token.Substring(7, token.Length - 7);

if (!tokenHandler.CanReadToken(sToken))
{
    return false;
}

JwtSecurityToken jwtToken = tokenHandler.ReadToken(sToken) as JwtSecurityToken;

if (jwtToken == null)
{
    return false;
}

TokenValidationParameters parameters = new TokenValidationParameters()
{
    ValidateIssuer = true,
    ValidateAudience = true,
    ValidateLifetime = true,
    RequireExpirationTime = true,
    ValidAudience = "http://localhost",
    ValidIssuer = "http://localhost",
    IssuerSigningKey = new SymmetricSecurityKey(Encoding.Default.GetBytes(StandardValues.SecretKey))
};

SecurityToken securityToken;
ClaimsPrincipal principal = tokenHandler.ValidateToken(sToken, parameters, out securityToken);

if (principal == null)
{
    return false;
}

} catch (Exception ex) { return false; }

return true;

And I have multiple controllers on which I want to perform the validation. Please let me know how can I perform this validation outside and before the actions, (into an action filter or another way) while sending the token as parameter for validation method.
