AI 解决方案
1. 错误翻译
原文：
openai.APIConnectionError: Connection error. 译文：OpenAI API连接错误：连接失败。
2. 原因分析
vlm_adapter.py第444行extract_drawing_info→第189行_call_api_with_logging→_base_client.py的request方法，最终因连接失败抛出错误。 3. 解决方案
import time
from openai import APIConnectionError
def safe_openai_call(client, kwargs, max_retries=3, delay=2):
"""带指数退避重试的OpenAI API调用"""
for attempt in range(max_retries):
try:
return client.chat.completions.create(**kwargs)
except APIConnectionError as e:
if attempt == max_retries - 1:
raise # 耗尽重试次数后抛原错误
time.sleep(delay * (2 ** attempt)) # 指数退避（2s→4s→8s）
return None
# 替换原_call_api_with_logging中的response赋值逻辑：
# response = safe_openai_call(self.client, kwargs)
4. 预防措施
tenacity库简化实现（@retry(stop=stop_after_attempt(3), wait=wait_exponential())）。 client.models.list()或requests.head(API_ENDPOINT)预检查连通性；生产环境可集成网络监控（如Prometheus+Blackbox Exporter）。 curl/telnet手动验证API端点可达性（如telnet api.openai.com 443）。
