OAuth承载令牌身份验证未通过签名验证-Java 学习之路

我在令牌使用者身上收到以下错误 . 任何解决这个问题的帮助都将非常受欢迎 . 谢谢 .

我能够将自己的签名验证添加到TokenValidationParameters然后我将JWT的传入Raw签名与此代码中的编译签名进行比较，如果匹配则签名有效 .

为什么使用内置签名验证没有发生这种情况超出了我的想法，也许这是vNext Identity令牌框架beta 6中的一个可能的错误 .

public void ConfigureServices（IServiceCollection services）

config.TokenValidationParameters.SignatureValidator =
                delegate (string token, TokenValidationParameters parameters)
                {
                    var clientSecret = "not the real secret";

                    var jwt = new JwtSecurityToken(token);

                    var hmac = new HMACSHA256(Convert.FromBase64String(clientSecret));

                    var signingCredentials = new SigningCredentials(
                       new SymmetricSecurityKey(hmac.Key), SecurityAlgorithms.HmacSha256Signature, SecurityAlgorithms.Sha256Digest);

                    var signKey = signingCredentials.SigningKey as SymmetricSecurityKey;


                    var encodedData = jwt.EncodedHeader + "." + jwt.EncodedPayload;
                    var compiledSignature = Encode(encodedData, signKey.Key);

                    //Validate the incoming jwt signature against the header and payload of the token
                    if (compiledSignature != jwt.RawSignature)
                    {
                        throw new Exception("Token signature validation failed.");
                    }

                    return jwt;
                };

Encode helper method

public string Encode(string input, byte[] key)
        {
            HMACSHA256 myhmacsha = new HMACSHA256(key);
            byte[] byteArray = Encoding.UTF8.GetBytes(input);
            MemoryStream stream = new MemoryStream(byteArray);
            byte[] hashValue = myhmacsha.ComputeHash(stream);
            return Base64UrlEncoder.Encode(hashValue);
        }
