用Java为hasura授权生成JWT令牌

Question

我们正在使用Spring引导作为后端，仅为auth和生成jwt令牌的其余部分在hasura中处理。

我面临正确生成JWT的问题。

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返回无效的签名。在哪里作为在节点

 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);
  },

jwt从节点

使用相同的密钥和算法工作得非常好。对于节点，我使用了jsonwebtoken库。

我找到了解决办法。字符串应转换为byte[]：

 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();
    }
