无需输入数据库密码即可使用Python连接到服务器上的数据库

import configparser
import MySQLdb

config = configparser.ConfigParser()
config.read('config.ini')

host = config.get('database', 'host')
port = config.get('database', 'port')
user = config.get('database', 'user')
password = config.get('database', 'password')
database = config.get('database', 'database')

conn = MySQLdb.connect(host=host, port=int(port), user=user, passwd=password, db=database)

import os
import MySQLdb

host = os.environ.get('DB_HOST')
port = os.environ.get('DB_PORT')
user = os.environ.get('DB_USER')
password = os.environ.get('DB_PASSWORD')
database = os.environ.get('DB_DATABASE')

conn = MySQLdb.connect(host=host, port=int(port), user=user, passwd=password, db=database)
