How can I fix my Flask server‘s 405 error that includes OpenAi api?

题意：解决包含OpenAI API的Flask服务器中出现的405错误（Method Not Allowed，即方法不允许）

问题背景：

I'm trying to add an API to my webpage and have never used any Flask server before, I have never used Javascript too so this is a completely brand new learning experience. My problem is that I keep receiving a 405 error code saying that the method is not allowed. I keep on using the POST method but it isn't working, I am banking that my issue may be with my HTML code more than my Flask server because the code is extremely generic and simple.

我正在尝试将API添加到我的网页中，但我之前从未使用过任何Flask服务器，也从未使用过JavaScript，所以这对我来说是完全全新的学习体验。我的问题是，我不断收到405错误代码，表示方法不允许。我一直在使用POST方法，但它不起作用。我认为我的问题可能更多地出在我的HTML代码上&#
