node.js - 不断收到 API 返回错误 : Error: Daily Limit for Unauthenticated Use Exceeded. 继续使用需要注册

Question

我关注了https://developers.google.com/drive/api/v3/quickstart/nodejs教程，我让它在控制台上列出文件，但是当我尝试返回 res.data.files 时，它给了我未定义的值和错误:API 返回了错误:

Error: Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup.

尝试从 listFiles 函数返回它

您已用完您的 key 的所有日常 API 调用。这是一项措施，这样您就不会淹没他们的系统。
