Python调用ChatGPT遇Cloudflare拦截报错的解决求助

按OpenAI官方文档编写Python代码调用ChatGPT功能，运行后触发openai.PermissionDeniedError，返回Cloudflare拦截页面。尝试更换OpenAI库版本、修改代码均无效，求解决方法。

代码示例 #

from openai import OpenAI

client = OpenAI(api_key='<我的API密钥>')

response = client.chat.completions.create(
  model="gpt-3.5-turbo",
  messages=[
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "Who won the world series in 2020?"},
    {"role": "assistant", "content": "The Los Angeles Dodgers won the World Series in 2020."},
    {"role": "user", "content": "Where was it played?"}
  ]
)

报错信息 #

• 配置合规代理：Cloudflare拦截大多因IP地区受限，需使用可访问OpenAI API的代理/VPN，并在客户端中配置代理：

  client = OpenAI(
      api_key='你的API密钥',
      proxies={
          "http": "http://代理地址:端口",
          "https": "http://代理地址:端口",
      }
  )
  

• 验证API密钥有效性：登录OpenAI后台确认密钥未过期、账户有可用余额，且密钥权限包含chat.completions接口调用权限。
• 添加自定义请求头：模拟浏览器请求头，避免被识别为异常请求：

  client = OpenAI(
      api_key='你的API密钥',
      headers={
          "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36"
      }
  )
  

• 控制请求频率：短时间内多次调用可能触发反爬机制，添加time.sleep()控制请求间隔，避免频繁请求。
• 检查网络环境：确保网络稳定，本地防火墙或安全软件未拦截API请求。
