前言:最近在学python,学到有关数据库的操作之时,想着把数据库的配置抽离出来,下面把代码贴出来~
db_config.py
class mysql_config():
def get_config(self, name):
config = {
'testdb': {
'host': '127.0.0.1',
'user': 'root',
'password': '123',
'database': 'test',
'port': 3306
}
}
return config[name]
通过config这个dict,用name去检索配置,一般数据库的配置分测试服(开发)数据库还有正式服数据库
db_mysql
import mysql.connector
from db_config import mysql_config
m_config = mysql_config()
class db_mysql_detail():
def __init__(self, name):
self.__name = name
self.__conn = self.build_conn(name)
self.__cursor = self.__conn.cursor()
@property
def conn(self):
return self.__conn
def build_conn(self, name):
try:
config = m_config.get_config(name)
con = mysql.connector.connect(**config)
return con
except mysql.connector.Error as err:
print('Something wrong: %s' % format(err))
def getAll(self,sql):
self.__cursor.execute(sql)
return self.__cursor.fetchall()
def close(self):
pass
使用pip下载mysql包,import类mysql.connector
assist.py
from db_mysql import db_mysql_detail
obj = db_mysql_detail('testdb')
sql = 'select * from user'
data = obj.getAll(sql)
print(data)
进行测试
