如何使用 Node.js 为 Google 服务帐户创建 JWT？

Question

根据这个guide，我已经使用 Java 示例成功地为 Google 服务帐户创建了 JWT，并且可以正常工作。然而，这些台词对我来说仍然是“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 为使用 Node.js 和 Java 创建的令牌显示相同的标头和正文。

所以，我假设签名是不同的。

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，从错误消息看来，这不是 JWT 特定的问题。这个 Google Groups post 表明问题是由于使用了不正确的 CURL 命令。检查 curl 命令语法并访问令牌放置以确保其有效。

Answer 2

突然之间，它可以在没有任何代码更改的情况下运行。
