Java验证解析token锁
引言
本文主要示例如何通过已知的公钥（字符串），来使用java-jwt校验token锁。
由于java-jwt中校验时所需要的公钥是RSAPublicKey对象而我们目前的公钥是字符串，所以我们需要进行转化，本篇文章主要就是记录如何进行这个转化
如果需要了解公钥、私钥的概念，请百度其它文章。
代码
<!-- java-jwt -->
<dependency>

<version>4.2.1</version>
</dependency>
/**
* 根据公钥字符串生成PublicKey对象

* @throws NoSuchAlgorithmException
* @throws InvalidKeySpecException
*/
private static PublicKey getPublicKey()
throws NoSuchAlgorithmException, InvalidKeySpecException {
String pem = "MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAuWCkZn1ksPM+DBLzgaffe2je6/Kr168fDI/CAM23Ardh4+w5yprtCmNfibCLcNZ66OzPC164p4ufboc9fxXqd5mv0ZtaHGG2pATH5e7z+Gla3Bd3QX8WqJi5LkAtsdP23IQqhz8UHA+Vmd6pTzobcQBhF1K7K/zcK9QDTFon4tCxL12wSOl40CDlWnaHortvljmJ5T3zD1iPjHjpVejI5YQReqxXEuqFVTqu2nhdTWAmfX8KrlVbPGPCevruKFmNvnl09N0Kk2CZGRlLq5aE7UZxH3GOkNWKkVWMO7tUgoJK9r8v/EIrIcuO5SX7RuyyhyY0/fsx3f+CTrUATkfgVwIDAQAB";
X509EncodedKeySpec pubKeySpec = new X509EncodedKeySpec(Base64.decodeBase64(pem));
KeyFactory keyFactory = KeyFactory.getInstance("RSA");
PublicKey publicKey = keyFactory.generatePublic(pubKeySpec);
System.out.println(publicKey);
return publicKey;
}
/**

* @throws Exception
*/
public static DecodedJWT verifierToken(String token)throws Exception{
//其实按照规定只需要传递 publicKey 来校验即可，这可能是auth0 的缺点
Algorithm algorithm = Algorithm.RSA256((RSAPublicKey) getPublicKey(),null);
JWTVerifier verifier = JWT.require(algorithm)
//.withIssuer(ISSUER)
.build(); //Reusable verifier instance 可复用的验证实例
DecodedJWT jwt = verifier.verify(token);
return jwt;
}
