Question

根据这个guide我已经使用Java示例为Google服务帐户成功创建了JWT，并且它已经运行了。然而，这些线对我来说仍然是“神奇的”：

GoogleCredential credential = GoogleCredential.fromStream(resourceAsStream);
PrivateKey privateKey = credential.getServiceAccountPrivateKey();

但我无法使用Node.js重复它。邮递员说“无法得到任何回应”。

这是我的代码。

const jwt = require('jsonwebtoken');

const TOKEN_DURATION_IN_SECONDS = 3600;

const issueJWT = (
  issuedAt = Math.floor(Date.now() / 1000),
  serviceAccount = require('path/to/service-account.json')
) =>
  jwt.sign(
    {
      'iss': serviceAccount.client_email,
      'sub': serviceAccount.client_email,
      'aud': `https://${SERVICE_NAME}/${API_NAME}`,
      'iat': issuedAt,
      'exp': issuedAt + TOKEN_DURATION_IN_SECONDS,
    },
    serviceAccount.private_key,
    {
      algorithm: 'RS256',
      header: {
        'kid': serviceAccount.private_key_id,
        'typ': 'JWT',
        'alg': 'RS256',
      },
    }
  );

Onlinde decoder显示使用Node.js和Java创建的标记的相同标题和正文。

所以，我认为签名是不同的。

通过java中的jwt：

curl --header "Authorization: Bearer {jwt-from-java}" https://bigtableadmin.googleapis.com/v2/projects/{project-name}/instances -v

如何使用Node.js为Google服务帐户创建JWT？

Answer 1

因此从错误消息来看，这似乎不是JWT的特定问题。此Google网上论坛post显示该问题是由于使用了错误的CURL命令所致。检查curl命令的语法并访问令牌位置以确保其有效。

Answer 2

突然之间，现在无需更改任何代码即可正常工作。
