如何在自己的客户端 - 服务器应用程序中使用System.IdentityModel

using System.IdentityModel;
using System.IdentityModel.Tokens;

// 创建一个JWT安全令牌处理程序
var jwtHandler = new JwtSecurityTokenHandler();

// 创建一个JWT安全令牌
var jwtToken = jwtHandler.CreateToken(new SecurityTokenDescriptor
{
    Issuer = "https://example.com",
    Audience = "https://example.com/api",
    SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(Encoding.UTF8.GetBytes("mysecret")), SecurityAlgorithms.HmacSha256Signature)
});

// 序列化JWT安全令牌
var jwt = jwtHandler.WriteToken(jwtToken);

// 验证JWT安全令牌
var validationParameters = new TokenValidationParameters
{
    ValidIssuer = "https://example.com",
    ValidAudience = "https://example.com/api",
    IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("mysecret"))
};
var principal = jwtHandler.ValidateToken(jwt, validationParameters, out SecurityToken securityToken);
