Python mysql 加密_使用加密的选项文件将Python连接到MySQL

我使用

mysql_config_editor创建一个带密码的.mylogin.cnf文件.我知道它工作正常,因为我可以使用它连接命令行实用程序mysql和R包R

MySQL没有问题.

但是,在尝试使用Mysql-Connector / Python进行连接时：

# using mysql-connector-python-rf

import os

import mysql.connector

con = mysql.connector.connect(option_files=os.path.expanduser('~/.mylogin.cnf'))

或者使用PyMySQL：

# using pymysql

import os

import pymysql

con = pymysql.connect(option_files=os.path.expanduser('~/.mylogin.cnf'))

我犯了同样的错误：

略过源代码,看起来这些正试图以明文形式读取文件.但是,mysql_config_editor会加密它生成的登录文件.在代码中手动输入密码时,两个模块都能正常工作.

如何使用这些生成的配置文件之一连接到Python？我使用的是Python 3,所以MySQLdb不是一个选项.

更新：现在,我正在使用RPy2在R中运行查询并将结果传回Python.代码有点难看,但工作流程并不是那么糟糕.

import myloginpath

import pymysql

conf = myloginpath.parse('client')

db = pymysql.connect(**conf, host='mydbhost', db='whatever')
