javascript - 从 Node.js 订阅 SalesForce 主题时出错

Question

我正在尝试使用 the documentation of JSForce 中提供的代码从 Node.js 服务器订阅 SalesForce 主题。 :

conn.streaming.topic("InvoiceStatementUpdates").subscribe(function(message) {
  console.log('Event Type : ' + message.event.type);
  console.log('Event Created : ' + message.event.createdDate);
  console.log('Object Id : ' + message.sobject.Id);
});

但是，我收到错误位置未定义

[1552904103100] ERROR (13143 on myuser): location is not defined
    ReferenceError: location is not defined

深入研究我发现的问题a comment in Github指出faye，它是 JSForce 的直接依赖项，只能在浏览器应用程序中使用。然而，JSForce 预计可以在客户端和服务器端工作。

任何关于为什么会发生这种情况的想法将不胜感激。谢谢!

我终于解决了在尝试streaming功能之前进行显式login()调用的问题。
