在.NET中验证/验证用PHP语言创建的JWT令牌

using Microsoft.IdentityModel.Tokens;

public bool ValidateJwtToken(string token, string publicKey)
{
    var tokenHandler = new JwtSecurityTokenHandler();
    var validationParameters = new TokenValidationParameters
    {
        ValidateIssuerSigningKey = true,
        IssuerSigningKey = new SymmetricSecurityKey(Encoding.ASCII.GetBytes(publicKey)),
        ValidateIssuer = false,
        ValidateAudience = false
    };

    try
    {
        SecurityToken validatedToken;
        tokenHandler.ValidateToken(token, validationParameters, out validatedToken);
        return true;
    }
    catch
    {
        return false;
    }
}

require_once 'vendor/autoload.php';

use Firebase\JWT\JWT;

$key = 'your_secret_key';
$payload = array(
    "sub" => "1234567890",
    "name" => "John Doe",
    "iat" => 1516239022
);

$jwt = JWT::encode($payload, $key, 'HS256');
