AWS Lambda 上的 Quickbooks API 应用程序：OAuth 仅连接一次

Question

我正在使用连接到 QBO API 的 AWS Lambda。

我的目标是每天通过 lambda cron 触发器运行一次。

Here is a gist of the oauth service I wrote >>

intuit-oauth version: 3.0.2

Node.js version 12

为了启动 OAuth，我从 QBO 游乐场获取了一个新的刷新令牌，并将其存储在 JSON 文件中。之后，我在更新时将刷新令牌写入 JSON 文件。我已经看到这项工作很好，我从这个项目中休息了大约一周，当我回到它时，我的 JSON 文件中的当前刷新令牌让我可以正常访问。但这当然只是局部的。

当我在本地运行测试时，它每次都能完美运行，在我将它部署到 AWS 后，如果我等待的时间不超过几分钟，它可能会运行一次或两次。如果我等待大约 15 分钟，我会收到以下错误：

来自 cmets： Lambda 容器将在几分钟不活动后被销毁，并且对磁盘或全局内存所做的任何更改都不会在此空闲期之后的调用中持久化，甚至不会在其他线程中持久化。

在当前示例中，Quickbooks 刷新令牌存储在磁盘中，不会被持久化，来自原始 lambda zip 的刷新令牌将在后续调用中使用。
