As mentioned, in .Net core we use

var tokenHandler = new JwtSecurityTokenHandler();
    
var token = tokenHandler.CreateToken(tokenDescriptor);
    
return tokenHandler.WriteToken(token);

Here what is the difference between CreateToken and WriteToken?

CodePudding user response：

CreateToken method create security token based on the specified token descriptor and return securitytoken object class.

WriteToken method returns string, i.e serializes the specified security token to a string.
