MySQL备份-警告密码不安全

Question

我使用Python编写了这个小脚本，以从数据库创建表的备份：

import subprocess
sql_cmd = 'mysql -B -u User -pPassword  -e Database "SELECT * FROMdevice;" > file.csv'
subprocess.run([sql_cmd], shell=True)

它正在运行，但是我收到了以下警告消息： mysql: [Warning] Using a password on the command line interface can be insecure.

如果可能，我想隐藏或删除警告。

Answer 1

从输入获取密码

import subprocess
import getpass

pswd = getpass.getpass('Password:')
sql_cmd = 'mysql -B -u User -p pswd  -e Database "SELECT * FROMdevice;" > 
file.csv'
subprocess.run([sql_cmd], shell=True)
