寫了小爬蟲，用到asyncio做異步，多次調(diào)用async with 和 await爬蟲操作，但是在其中沒調(diào)用異步的數(shù)據(jù)庫操作沒有成功，代碼下:

async with session.get(restaurant_url) as restaurant_rep:

restaurant_rep = await restaurant_rep.json()

rating_url = RES_URL.format(restaurant_id=restaurant_id)

async with session.get(rating_url) as rating_rep:

rating_rep = await rating_rep.json()

overall_rating, service_rating, food_rating = format_rating_data(rating_rep)

add_restaurant_data(restaurant_rep, overall_rating, service_rating, food_rating)

food_url = constants.ELE_FOOD_JSON.format(restaurant_id=restaurant_id)

async with session.get(food_url) as food_rep:

food_rep = await food_rep.json()

for food_type in food_rep:

for food in food_type['foods']:

food_id = food['specfoods'][0]['food_id']

if food_id not in food_set:

food_set.add(food_id)

add_food_data(food)

add_*函數(shù) 解析response并寫入數(shù)據(jù)庫， 但是8行寫操作并沒有寫成功， 函數(shù)沒問題， 19行寫數(shù)據(jù)庫操作可以，求問一下為什么

順便問一下這樣寫有什么不好？
