我在脚本中使用python mysql.connector模块时遇到问题。当我从脚本运行连接到运行mysql v8的docker容器时，它试图连接到错误的ip地址。下面是示例函数：

import mysql.connector
def connect():
    db =  mysql.connector.connect(
        host="172.17.0.2",
        user="user",
        passwd="password",
        auth_plugin='mysql_native_password')

运行此操作时，会产生以下错误：mysql.connector.errors.programmingerror:1045（28000）：用户'user'@'172.17.0.1'的访问被拒绝（使用密码：yes）
这是我试图连接到的docker容器的ip
ipaddress:“172.17.0.2”
真正有趣的是，在交互式python会话中使用mysql.connector时，我可以很好地连接到数据库。见下文

Python 3.7.2 (default, Jan 16 2019, 19:49:22) 
[GCC 8.2.1 20181215 (Red Hat 8.2.1-6)] on linux

>>> import mysql.connector
>>> db =  mysql.connector.connect(
... host="172.17.0.2",
... user="user",
... passwd="passwd",
... auth_plugin='mysql_native_password')
>>> mycursor =  db.cursor()
>>> mycursor.execute("show databases")
>>> for x in mycursor: print(x)
... 
('food',)
('information_schema',)

这是我在Fedora29上运行的mysql连接器的版本

pip list |grep mysql-connector
mysql-connector-python 8.0.15

有没有想过是什么导致从脚本运行此脚本失败？
