python
import time
import requests
from requests.adapters import HTTPAdapter
from urllib3.util.retry import Retry
def create_session_with_retry():
    """创建带重试机制的会话"""
    session = requests.Session()
    
    # 配置重试策略
    retry_strategy = Retry(
        total=8,  # 最大重试次数
        backoff_factor=1,  # 重试等待时间因子
        status_forcelist=[500, 502, 503, 504],  # 需要重试的状态码
        allowed_methods=["POST", "GET"]
    )
    
    adapter = HTTPAdapter(max_retries=retry_strategy)
    session.mount("http://", adapter)
    session.mount("https://", adapter)
    
    return session
使用示例

session = create_session_with_retry()
try:
    response = session.post(
        "https://www.dmxapi.cn/v1beta/models/gemini-2.0-pro-ssvip:generateContent",
        timeout=30,
        headers={"Content-Type": "application/json"}
    )
except requests.exceptions.RequestException as e:
    print(f"API请求失败: {e}")
