【中文标题】IDX10503:签名验证失败。托肯没有孩子。尝试的键:\'System.Text.StringBuilder\'【英文标题】:IDX10503: Signature validation failed. Token does not have a kid. Keys tried: 'System.Text.StringBuilder'IDX10503:签名验证失败。托肯没有孩子。尝试的键:'System.Text.StringBuilder' 【发布时间】:2021-08-12 06:33:53 【问题描述】:我有以下 JWT 令牌,
eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJjbGllbnRpZCIsImF1ZCI6ImNsaWVudGlkIiwic3ViIjoiMTIzIiwiYSI6IjQ1NiIsImlhdCI6MTYyMTc5OTU5OCwiZXhwIjoxNjIxNzk5NjU4fQ.hglbX63zhPwTOsB-zSiOMfxEKl5OaIk6zX1o9-LEhP3nro8fa5_3QyIH7I5971j-xuO1bccX1TOh0kNcQ-ACAg
这是使用生成的,
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, "clientid"),
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);
但我遇到了错误,
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'.
【问题讨论】:
jwt.io 说签名已验证 再试一次。它告诉错误的签名 否,已验证。 我发现了问题。使用 Convert.FromBase64String 而不是 Encoding.UTF8.GetBytes 【参考方案1】:我收到相同的错误消息,但我的问题不同。问题出在这一行:
new Ed25519PublicKeyParameters(Encoding.UTF8.GetBytes(key), 0);
所以我改成这样:
new Ed25519PublicKeyParameters(Convert.FromBase64String(key), 0);
密钥以 base64 格式保存到文件中,但我将其加载为 UTF8 字节。
【讨论】:
是的,这与我遇到的问题相同,但在您的情况下,情况并非如此,换句话说,它是编码字节问题:)【参考方案2】:问题是这一行,
var hmac = new HMACSHA512(Convert.FromBase64String(key));
我改成,
var hmac = new HMACSHA512(Encoding.UTF8.GetBytes(key));
该错误具有误导性。错误的源代码在https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/blob/d6f2b66d788195b50f2b1f700beb497851194c73/src/System.IdentityModel.Tokens.Jwt/JwtSecurityTokenHandler.cs#L1016
【讨论】:
干得好。在string.IsNullOrEmpty(jwtToken.Header.Kid);
和keysAttempted.Length > 0
发生时任何 都会引发错误,这是误导性的。以上是关于IDX10503:签名验证失败。托肯没有孩子。尝试的键:'System.Text.StringBuilder'的主要内容,如果未能解决你的问题,请参考以下文章
