IDX10503：签名验证失败令牌没有孩子尝试过的键：'System.Text.StringBuilder'

问题描述

我有以下 JWT 令牌，

eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJjbGllbnRpZCIsImF1ZCI6ImNsaWVudGlkIiwic3ViIjoiMTIzIiwiYSI6IjQ1NiIsImlhdCI6MTYyMTc5OTU5OCwiZXhwIjoxNjIxNzk5NjU4fQ.hglbX63zhPwTOsB-zSiOMfxEKl5OaIk6zX1o9-LEhP3nro8fa5_3QyIH7I5971j-xuO1bccX1TOh0kNcQ-ACAg

使用,

    public static string GenerateToken(string key,string a1,string a2)
    {
        var securityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(key));
        var token = new JwtSecurityToken(
            claims: new Claim[]
            {
            new Claim(JwtRegisteredClaimNames.Iss,"clientid"),new Claim(JwtRegisteredClaimNames.Aud,new Claim(JwtRegisteredClaimNames.Sub,a1),new Claim("a",a2),new Claim(JwtRegisteredClaimNames.Iat,DateTimeOffset.UtcNow.ToUnixTimeSeconds().ToString(),ClaimValueTypes.Integer64),},//notBefore: new DateTimeOffset(DateTime.Now).DateTime,expires: new DateTimeOffset(DateTime.Now.AddMinutes(1)).DateTime,signingCredentials: new SigningCredentials(securityKey,SecurityAlgorithms.HmacSha512)
        );

        return new JwtSecurityTokenHandler().WriteToken(token);
    }

var key = "Ym7AD3OT2kpuIRcVAXCweYhV64B0Oi9ETAO6XRbqB8LDL3tF4bMk9x/59PljcGbP5v38BSzCjD1VTwuO6iWA8uzDVAjw2fMNfcT2/LyRlMOsynblo3envlivtgHnKkZj6HqRrG5ltgwy5NsCQ7WwwYPkldhLTF+wUYAnq28+QnU=";
// Key is test                
var token = GenerateToken(key,"123","456");

获得令牌后，我正在使用以下代码进行验证，

var key = "Ym7AD3OT2kpuIRcVAXCweYhV64B0Oi9ETAO6XRbqB8LDL3tF4bMk9x/59PljcGbP5v38BSzCjD1VTwuO6iWA8uzDVAjw2fMNfcT2/LyRlMOsynblo3envlivtgHnKkZj6HqRrG5ltgwy5NsCQ7WwwYPkldhLTF+wUYAnq28+QnU=";
// key is test

var hmac = new HMACSHA512(Convert.FromBase64String(key));
var validationParameters = new TokenValidationParameters
            {
                ValidAudience = "clientid",ValidIssuer = "clientid",IssuerSigningKey = new SymmetricSecurityKey(hmac.Key)
            };
            var tokenHandler = new JwtSecurityTokenHandler();
            return tokenHandler.ValidateToken(token,validationParameters,out var validToken);

但是我遇到了以下错误，

IDX10503: Signature validation failed. Token does not have a kid. Keys tried: 'System.Text.StringBuilder'.
Exceptions caught:
 'System.Text.StringBuilder'.
token: 'System.IdentityModel.Tokens.Jwt.JwtSecurityToken'.
