    # 获取指定日期的指数、股票数据
    stock_rs = bs.query_all_stock(date)
    stock_df = stock_rs.get_data()
    data_df = pd.DataFrame()
    for code in stock_df["code"]:
        print("Downloading :" + code)
        k_rs = bs.query_history_k_data_plus(code, "date,code,open,high,low,close", date, date)
        data_df = data_df.append(k_rs.get_data())
    bs.logout()
    data_df.to_csv("D:\\demo_assignDayData.csv", encoding="gbk", index=False)
    print(data_df)
