共用 Helper 函数

Yahoo Finance crumb 管理器

Yahoo quoteSummary/options 等 v7/v10 接口需要 cookie+crumb。以下 helper 自动获取并缓存：

import requests

_yahoo_session = None

def get_yahoo_session() -> requests.Session:
    """获取带 crumb 的 Yahoo Finance session（自动缓存）"""
    global _yahoo_session
    if _yahoo_session and hasattr(_yahoo_session, '_crumb'):

    s.headers['User-Agent'] = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36'
    
    # Step 1: 获取 cookie
    s.get('https://fc.yahoo.com', timeout=10)
    
    # Step 2: 获取 crumb
    r = s.get('https://query2.finance.yahoo.com/v1/test/getcrumb', timeout=10)
    r.raise_for_status()
    s._crumb = r.text

        'crumb': s._crumb,
    }, timeout=15)
    r.raise_for_status()
    results = r.json().get('quoteSummary', {}).get('result', [{}])
    return results[0] if results else {}

Layer 1: 行情层

1.1 美股实时行情 — 新浪 + 腾讯

两个独立数据源。新浪最长可回溯到 1984 年；Yahoo 适合需要复权数据的场景。
