查询购物车Line串接

处理PostBack Evevnt，查询资料库，传送给使用者

实作

Server.py

@handler.add(PostbackEvent)
def handler_postback(event):
    prof = line_bot_api.get_profile(event.source.user_id)
    data = event.postback.data
    print(f"data:{data}")

        replay_text = '\n'.join(str(v) for v in cart_info) + f"\n总共:{cart_amount}元"
        line_bot_api.reply_message(
            event.reply_token,
            TextSendMessage(text=replay_text)
        )

dbpm.py

def QUY_Shopping_Cart_info_by_uid(self, uid):
    scid = self.INS_QUY_SC(uid)

    prodlist = []
    tot_price = 0

    shopping_list = self.QUY_Shopping_Cart_by_scid(scid)
    if(not shopping_list):
        return False
    for prod in shopping_list:
        product_name, product_price = self.QUY_Prod_Name_and_Price_by_pid(prod[0])
        prodlist.append(f"{product_name} * {prod[1]}")
        tot_price = tot_price + product_price * prod[1]

    return prodlist, tot_price
