PyMySQL 是在 Python3.x 版本中用于连接 MySQL 云服务器的一个库,Python2中则使用mysqldb
话不多说,直接上代码来说明用途
#!/user/bin/env python
#coding=utf-8
from pymysql import connect,cursors
from pymysql.err import OperationalError
import os
import configparser as cparser
from builtins import int
from framework.logger import Logger
import time
'''
========读取config.ini文件中mysql配置========
'''
base_dir = str(os.path.dirname(os.path.dirname(file)))
file_path = base_dir + "\config\config.ini"
cf = configUtil(file_path)
host = cf.get("sitmysqlconf", "host")
port = cf.get("sitmysqlconf", 'port')
db = cf.get("sitmysqlconf", 'db_name')
user = cf.get("sitmysqlconf", 'user')
password = cf.get("sitmysqlconf", 'password')
logger = Logger(logger="mysqlUtils").getlog()
'''
