我希望a chatbot在MySQL数据库中记录数据。但是，我没有太多使用SQL管理SQL数据库的经验。我在文件ActionBookRoom中有一个action.py类，它调用与SQL的连接，并希望记录我发送给它的信息：name_room，day，hour_start，duration。
我知道我必须通过以下方式建立与数据库的连接：
cnx = connector.connect(host='I_really_don_t_know_what_to_use_here', password='my_pass_that_works_on_mysqlcmd', user="root", database="the_database")
我已经有一些问题需要建立连接，因此，我有更多的问题要知道如何存储数据。
class ActionBookRoom(Action):
def name(self):
return 'action_room'
def run(self, dispatcher, tracker, domain):
print("inside run")
name_room = tracker.get_slot('name_room')
day = tracker.get_slot('day')
hour_start = tracker.get_slot('hour_start')
duration = tracker.get_slot('duration')
booking_answer = make_a_booking(name_room, day, hour_start, duration)
print("passed booking")
if booking_answer:
booking_answer = 'The reservation has been made'
else:
booking_answer = 'The room is taken at this hour'
response = """You want to book the {} room on {} at {} for {}. Is it correct ?""".format(name_room, day, hour_start, duration)
name_room = str(name_room)
day = str(day)
hour_start = str(hour_start)
duration = str(duration)
print("before connexion")
#SQL queries#
cnx = connector.connect(host='I_don_t_know_what_to_use_here', password='my_mysql_cmd_password', user="root", database="the_database")
print("after connexion")
dispatch = dispatcher.utter_message(response)
dispatch = dispatcher.utter_message(str(booking_answer))
return dispatch
返回给我的错误是Access denied for user 'root'@'localhost' (using password: YES)。即使我使用mike：

我使用MySQLWorbench但我仍然是新手。我可以使用my_password访问MySQL 8.0 CLI，获取用户：
mysql> SELECT User FROM mysql.user;
+------------------+
| User |
+------------------+
| mike |
| mysql.infoschema |
| mysql.session |
| mysql.sys |
| root |
+------------------+
5 rows in set (0.00 sec)
即使我提供了有效的密码或Access denied for user 'root' @ 'localhost' (using password: YES)，我也有mike
我应该重新安装MySQL吗？
我重新安装了MySQL并使用CLI尝试了它，它可以工作：
(staenv) C:\Users\antoi\Documents\Programming\Nathalie\18_2_2019\starter-pack-rasa-stack>python
Python 3.6.7 (v3.6.7:6ec5cf24b7, Oct 20 2018, 13:35:33) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import mysql.connector
>>> db = mysql.connector.connect(
... host="localhost",user="root",password="MySQL.2019",database="alex")
>>>
>>> cursor = db.cursor()
>>> cursor.execute("SELECT * FROM reservations")
>>> myresult = cursor.fetchall()
>>> for x in myresult:
... print(x)
...
(1, 'red', datetime.datetime(2018, 8, 8, 12, 0), None)
(2, 'red', datetime.datetime(2018, 8, 8, 12, 0), None)
>>>
但是，当我尝试从文件actions.py执行此操作时，我仍然有错误
您可以使用以下连接器
cnx = connector.connect(host='I_really_don_t_know_what_to_use_here', password='your_password', user="mike", database="the_database")
