php - 无法从 Nest 服务器获取访问 token

Question

我在获取 Nest 的访问 token 时遇到问题。

我的 node.js 应用程序上有 nest-api，但我无法获取访问 token 。

如果我从不同的客户端、设备甚至帐户连接都没有关系。

我曾经使用 php 代码自动执行 oAuth 2.0 获取 token 的过程，它工作正常，但它停止工作了。

无论我输入“OAuth 重定向 URL”以自动获取 token 还是只是尝试不使用 URL 来获取 token ，我总是会收到此错误:

An error occurred. An error occurred while fetching client info

仅此而已，没有日志条目或任何内容，只有那条非描述性消息。

例如，如果我创建一个新帐户，然后向该帐户添加一个客户端，我会得到一个 URL，我可以在其中检索想要从我的客户端控制其嵌套产品的用户帐户的访问 token -- URL看起来像这样:

https://home.testc.nestlabs.com/login/oauth2?client_id=XXXXX&state=STATE

当您输入此 URL 时，它会询问您的 Nest 凭据，然后生成一个访问 token 。 这在执行完全相同的步骤时工作正常，但现在它甚至不要求提供凭据，我得到的只是这条消息，没有别的。

我编写了这个批处理文件来帮助快速测试 Nest API 读/写和 OAuth 协商。抱歉有点乱，但希望对您有所帮助。您需要下载 curl 包并指向它。也在pastebin .另存为 .bat 并根据需要注释/取消注释 rem 行。
