import sys; sys.path.insert(0, "dianping-api/scripts")
from dianping_api import api_search, api_shop, api_deals

# Search
results = api_search("陆家嘴火锅", city_id=1)
for s in results["shops"]:
    print(s["shop_id"], s["name"], s.get("rating"))

# Shop detail
info = api_shop("l7UgWvw6yZ7ytaly")
print(info["scores"], info["recommended_dishes"])

Typical AI Workflow

1. 根据用户意图组合 keyword（地点+菜系+场景），选对 city_id
   例: 用户说"北京故宫附近吃烤鸭" → search("故宫 烤鸭", city_id=2)
   例: 用户说"上海迪士尼带娃吃饭" → search("迪士尼 亲子餐厅", city_id=1)
   例: 用户说"杭州西湖附近日料"   → search("西湖 日料", city_id=5)

2. api_search(keyword, city_id) → 拿到 shop_id 列表
3. api_shop(shop_id)            → 评分、推荐菜、地址、交通
4. api_deals(shop_id)           → 优惠券、套餐、价格
5. 整理推荐给用户（含评分、人均、推荐菜、优惠信息）
