为hasura授权生成Java中的JWT令牌

Question

我们使用spring-boot作为后端，仅用于auth，生成jwt令牌rest在hasura中处理。

我在正确生成JWT时遇到了问题。

public String generateToken(String email,String role,Long id)  {
Map<String, Object> claims = new HashMap<>();
Map<String,Object> claim =new HashMap<>();
claims.put("x-hasura-user-id",id);
claims.put("x-hasura-default-role",role);
claims.put("x-hasura-allowed-roles", new String[]{"job_seeker", "employer", "admin"});
claim.put("https://hasura.io/jwt/claims",claims);
System.out.println(claim);
return doGenerateToken(claim, email);
}
private String doGenerateToken(Map<String, Object> claim, String subject) {
return Jwts.builder().setClaims(claim).setSubject(subject).setIssuedAt(new Date(System.currentTimeMillis()))
.setExpiration(new Date(System.currentTimeMillis() + Long.parseLong(tokenValidity))).signWith(SignatureAlgorithm.HS256, secret).compact();
}

这是生成jwt令牌作为

但它hasura正在返回无效签名。在节点中

generateToken: (user: any) => {
const payload = {
sub: user.email,
"https://hasura.io/jwt/claims": {
"x-hasura-default-role": `${user.role.name}`,
"x-hasura-user-id": `${user.id}`,
"x-hasura-allowed-roles": ["job_seeker", "employer", "admin"],
},
};
return jwt.sign(payload, secretkey);
},

来自节点的jwt

使用相同的密钥和算法可以很好地工作。对于节点，我使用了jsonwebtoken库。

我找到了解决方案。字符串应转换为字节[]：

private String doGenerateToken(Map<String,Object> header,Map<String, Object> claim, String subject) {
return Jwts.builder().setHeader(header).setClaims(claim).setSubject(subject).setIssuedAt(new Date(System.currentTimeMillis()))
.setExpiration(new Date(System.currentTimeMillis() + Long.parseLong(tokenValidity))).signWith(SignatureAlgorithm.HS256, secret.getBytes(StandardCharsets.UTF_8)).compact();
}
