c# - 如何使用.net core中的SecurityTokenDescriptor将kid添加到jwt header

Question

我使用 .netcore 2 和 JwtSecurityToken 来生成 token

            var jwtSecurityToken = new JwtSecurityToken(
                issuer: issuer,
                audience:issuer,
                claims: claims,
                expires: DateTime.Now.AddMinutes(5),
                signingCredentials: new SigningCredentials(key, SecurityAlgorithms.HmacSha256)
            );

            jwtSecurityToken.Header.Add("kid", requestAPIKey);

现在，因为我使用 Idenity，所以我已从 JwtSecurityToken 切换到安全 token 描述符，我的代码是:

            var tokenDescriptor = new SecurityTokenDescriptor
            {
                Subject = new ClaimsIdentity(claims),
                Expires = DateTime.Now.AddDays(1),
                SigningCredentials = creds
            };

我的问题是在使用安全 token 描述符时如何将 child 添加到我的 token header ？在 JwtSecurityToken 中，我使用以下代码添加它:

jwtSecurityToken.Header.Add("kid", requestAPIKey);

我如何使用 SecurityTokenDescriptor 做同样的事情？谢谢你!

这是我使用过的代码片段:

var tokenHandler = new JwtSecurityTokenHandler(); 
        var key = Encoding.UTF8.GetBytes("Secret"); 
        var tokenDescriptor = new SecurityTokenDescriptor 
        { 
            Subject = new ClaimsIdentity(new Claim[] 
            { 
                new Claim(ClaimTypes.Name, UserId), 
                new Claim(name, value), 
                new Claim(name, value)
            }), 

            Expires = DateTime.UtcNow.AddMinutes(5), 
            SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(key), SecurityAlgorithms.HmacSha256Signature) 

        }; 

        var token = tokenHandler.CreateJwtSecurityToken(tokenDescriptor); 
        token.Header.Add("kid", ""); 

        token.Payload.Remove("iss"); 
        token.Payload.Add("iss", "your issuer"); 

        var tokenString = tokenHandler.WriteToken(token);
