The javadoc https://github.com/auth0/java-jwt/blob/7dcea427df1db2b948911e70aef2e9d7f0b7cfad/lib/src/main/java/com/auth0/jwt/algorithms/Algorithm.java#L171-L178说你需要提供原始秘密值。
这意味着你需要base64
-解码您当前拥有的值:
import com.auth0.jwt.JWT;
import com.auth0.jwt.JWTVerifier;
import com.auth0.jwt.algorithms.Algorithm;
import com.auth0.jwt.exceptions.JWTVerificationException;
import com.auth0.jwt.interfaces.DecodedJWT;
import java.io.UnsupportedEncodingException;
import java.util.Base64;
public class JwtVerification {
private static final String SECRET = "zZrq0sZK1yt9RJk51RTJ/jeU6WERbvr8nqKMWQJRX1E=";
public static DecodedJWT verify(String token) throws JWTVerificationException, UnsupportedEncodingException {
JWTVerifier verifier = JWT.require(Algorithm.HMAC256(Base64.getDecoder().decode(SECRET)))
.withIssuer("auth0")
.acceptLeeway(1)
.acceptExpiresAt(5 * 60)
.build();
return verifier.verify(token);
}
public static void main(String[] args) throws UnsupportedEncodingException {
final String token = "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ0aWQiOiJiZWJlMjM4Zi1iMGM4LTQwYzMtOTYyMC1jZDRlOGUyMzIwZGMiLCJvaWQiOiI5MjJjMmZiNC0zNWI1LTExZDctOWE2NC0wMGIwZDBmY2I5ZTMiLCJzdWIiOiI5MjJjMmZiNC0zNWI1LTExZDctOWE2NC0wMGIwZDBmY2I5ZTMiLCJlbWFpbCI6InRlc3RAdGVzdC5jb20iLCJpYXQiOjE1MTg0NDk5NzYsImV4cCI6MTUxODQ1MzU3NiwibmJmIjoxNTE4NDQ5OTc2fQ.6InknrU67g_HEkaLxD9Ul5vOzbYGf54mJNcSyPr-xek";
System.out.println(verify(token));
}
}
我目前收到此异常,但看起来令牌本身有问题:
Exception in thread "main" com.auth0.jwt.exceptions.InvalidClaimException: The Claim 'iss' value doesn't match the required one.
at com.auth0.jwt.JWTVerifier.assertValidStringClaim(JWTVerifier.java:424)
at com.auth0.jwt.JWTVerifier.verifyClaims(JWTVerifier.java:382)
at com.auth0.jwt.JWTVerifier.verify(JWTVerifier.java:355)
at com.swiftkey.parametron.data.JWT2.verify(JWT2.java:23)
at com.swiftkey.parametron.data.JWT2.main(JWT2.java:28)
事实上,令牌没有指定iss
字段,但验证者希望它是“auth0”,因为.withIssuer("auth0")
.
如果你查看令牌内部:
final String token = "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ0aWQiOiJiZWJlMjM4Zi1iMGM4LTQwYzMtOTYyMC1jZDRlOGUyMzIwZGMiLCJvaWQiOiI5MjJjMmZiNC0zNWI1LTExZDctOWE2NC0wMGIwZDBmY2I5ZTMiLCJzdWIiOiI5MjJjMmZiNC0zNWI1LTExZDctOWE2NC0wMGIwZDBmY2I5ZTMiLCJlbWFpbCI6InRlc3RAdGVzdC5jb20iLCJpYXQiOjE1MTg0NDk5NzYsImV4cCI6MTUxODQ1MzU3NiwibmJmIjoxNTE4NDQ5OTc2fQ.6InknrU67g_HEkaLxD9Ul5vOzbYGf54mJNcSyPr-xek";
final DecodedJWT decodedJwt = JWT.decode(token);
System.out.println("Header = " + decodedJwt.getHeader());
System.out.println("Algorithm = " + decodedJwt.getAlgorithm());
System.out.println("Audience = " + decodedJwt.getAudience());
decodedJwt.getClaims().forEach((k, v) -> {
System.out.println("Claim " + k + " = " + v.asString());
});
System.out.println("ContentType = " + decodedJwt.getContentType());
System.out.println("ExpiresAt = " + decodedJwt.getExpiresAt());
System.out.println("Id = " + decodedJwt.getId());
System.out.println("Issuer = " + decodedJwt.getIssuer());
System.out.println("Subject = " + decodedJwt.getSubject());
你会看到Issuer
场是null
Header = eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9
Algorithm = HS256
Audience = null
Claim sub = 922c2fb4-35b5-11d7-9a64-00b0d0fcb9e3
Claim nbf = null
Claim oid = 922c2fb4-35b5-11d7-9a64-00b0d0fcb9e3
Claim exp = null
Claim iat = null
Claim tid = bebe238f-b0c8-40c3-9620-cd4e8e2320dc
Claim email = [email protected] /cdn-cgi/l/email-protection
ContentType = null
ExpiresAt = Mon Feb 12 16:39:36 GMT 2018
Id = null
Issuer = null
Subject = 922c2fb4-35b5-11d7-9a64-00b0d0fcb9e3
生成该令牌的人没有指定Issuer
(aka iss
) 场地。
因此验证失败,因为我们设置验证者期望iss
等于auth0
.
