sockets - Google 可以存储 ETIMEDOUT 连接问题

Question

我们在节点服务器上使用@google-cloud/storage 包，并且在打开连接到 google-cloud 存储的套接字时看到了间歇性连接问题。看起来问题与身份验证有关，但我试图弄清楚为什么会发生这样的事情？任何帮助将不胜感激，如果有更多信息有助于理解问题，请告诉我，这样如果其他人面临同样的问题，它也可以帮助他们。

创建套接字的代码：

export function createGCSBucketClient(options = defaultGCSOptions) {
  const { projectId, keyFilename, bucketName } = options;
  const gcs = require('@google-cloud/storage')({ // eslint-disable-line global-require
    projectId,
    keyFilename,
  });
  return gcs.bucket(bucketName);
}

然后在我们的代码中的多个地方使用这个函数。
