3.解决方案

import requests
import time

def safe_model_call(api_url, api_key, payload, max_retries=3):
    headers = {"Authorization": f"Bearer {api_key}", "Content-Type": "application/json"}
    for attempt in range(max_retries):
        try:
            response = requests.post(api_url, json=payload, headers=headers, timeout=20)
            response.raise_for_status()  # 捕获HTTP错误（如401/500）
            
            if not response.text.strip():  # 校验空响应
                raise ValueError("模型返回空内容")
                
            return response.json()
        except (requests.exceptions.RequestException, ValueError) as e:
            print(f"尝试 {attempt+1}/{max_retries} 失败: {str(e)}")
            if attempt < max_retries - 1:
                time.sleep(2 ** attempt)  # 指数退避重试
            else:
                raise RuntimeError("模型调用最终失败") from e

# 使用示例
api_url = "https://api.dmxapi.com/v1/chat/completions"
api_key = "your_valid_api_key"
payload = {"model": "dmx-7b", "messages": [{"role": "user", "content": "你好"}]}

try:
    result = safe_model_call(api_url, api_key, payload)
    print("模型响应:", result)
except Exception as e:
    print("最终错误:", e)
