                wait = base_delay * (2 ** attempt)  # 指数退避等待
                print(f"⚠️ 速率限制触发，第{attempt+1}次重试前等待{wait}s")
                time.sleep(wait)
                continue
            raise  # 非速率错误直接抛出
    raise Exception("❌ 超过最大重试次数（速率限制未缓解）")

# 使用示例
if __name__ == "__main__":
    url = "https://api.dmxapi.com/v1/your_endpoint"
    headers = {"Authorization": "Bearer YOUR_API_KEY"}
    data = {"prompt": "你的请求内容"}
    
    try:
        result = call_dmxapi_safe(url, headers, data)
        print("✅ 请求成功:", result)
    except Exception as e:
        print("❌ 最终失败:", e)

以上方案可直接适配DMXAPI调用场景，核心是通过退避重试+前置控速规避速率限制。
