如何在C中的JWT令牌中添加字段#

我想创建一个示例控制台应用程序来生成以下格式的JWT令牌。我创建了一个简单的控制台应用程序来生成JWT,但在如何将所有必需的字段添加到上有点困难。 下面是我的控制台应用程序代码示例。

Console.WriteLine("");
string key = "dummykey";
var securityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(key));
var credentials = new SigningCredentials
                  (securityKey, SecurityAlgorithms.HmacSha256Signature);
var header = new JwtHeader(credentials);

//Some dummy PayLoad
var payload = new JwtPayload
           {
               { "firstname ", "lastname "},
               { "scope", "read,write"},
           };

var secToken = new JwtSecurityToken(header, payload);
var handler = new JwtSecurityTokenHandler();

var tokenString = handler.WriteToken(secToken);

Console.WriteLine("JWT Token is : ");
Console.WriteLine(tokenString);

Console.ReadLine();

上面的代码生成了一个JWT,格式如下。

HEADER:ALGORITHM & TOKEN TYPE

{
  "alg": "http://www.w3.org/2001/04/xmldsig-more#hmac-sha256",
  "typ": "JWT"
}
PAYLOAD:DATA

{
  "firstname ": "lastname ",
  "scope": "read,write"
}
VERIFY SIGNATURE

HMACSHA256(
  base64UrlEncode(header) + "." +
  base64UrlEncode(payload),
)

我想要它如下。

{
"schema":"value",
"majver":1,
"minver":0,
"sub":"value",
"scope":"read,write",
"iss":"value",
"exp":date,
"nbf":date,
"iat":date,
"jti":"value",
"emp_id":"value",
"act":
   {
      "typ":"value",
      "sub":"value"
   }
}
