Use VS to test the AzureOpenai API. It doesn't work, but it can be used in Azure and on the AMA client?

Question

Use VScode to test the AzureOpenai API, but it can be used in Azure and on the AMA client? code show as below:

#Note: The openai-python library support for Azure OpenAI is in preview.
import os
import openai
openai.api_type = "azure"
openai.api_base = "https://?????.openai.azure.com/"
openai.api_version = "2023-03-15-preview"
openai.api_key = os.getenv("OPENAI_API_KEY")

response = openai.ChatCompletion.create(
  engine="abc123",
  messages = [{"role":"system","content":"You are an AI assistant that helps people find information."},{"role":"user","content":"你好"},{"role":"assistant","content":"您好！有什么我可以为您效劳的吗？"}],
  temperature=0.7,
  max_tokens=800,
  top_p=0.95,
  frequency_penalty=0,
  presence_penalty=0,
  stop=None)

Here I am hidden, my KEY, prompts the following error:

   raise openai.error.AuthenticationError(
openai.error.AuthenticationError: No API key provided. You can set your API key in code using 'openai.api_key = 
<API-KEY>', or you can set the environment variable OPENAI_API_KEY=<API-KEY>). If your API key is stored in a file, you can point the openai module at it with 'openai.api_key_path = <PATH>'. You can generate API keys in the 
OpenAI web interface. See https://platform.openai.com/account/api-keys for details.

Please some great god to guide me.
