我可以使用配置文件保存连接字符串参数吗？

Question

我有一个连接到数据库的脚本。我想从脚本中提取服务器、用户、密码和数据库，并将其放入配置文件中。我成功地从配置文件中提取值。我的问题是pymssql.connect语法中有变量时失败。我把我的示例代码粘贴在下面。这可能吗？在

###database connection  
config = configparser.ConfigParser()  
config.read('test.config')  
server = config['DEFAULT']['SQLServer']  
db = config['DEFAULT']['Database']  
user = config['DEFAULT']['User']  
password = config['DEFAULT']['Password']  

###this works  
####conn = pymssql.connect(host='Server1', user='Joe',password='MyPass', database='MyDB')

###this doesn't
try:
    conn = pymssql.connect(host=server, user=user,password=password, database=db)
except Exception as e:
    print(str(e))
    sys.exit()

Answer 1

这就是我检索连接属性和连接的sql server数据库的方法

**App.ini file**

[CoreContext]
host=sservername.database.windows.net
user=dbuser@servername
password=password
database=DeltaXCore



**Connection.py file**

appConfig = ConfigParser.ConfigParser()
appConfig.read("App.ini")
ConnectionString.HOST = appConfig.get("CoreContext", "host")
CoreConnectionString.USER = appConfig.get("CoreContext", "user")
CoreConnectionString.PASSWORD = appConfig.get("CoreContext", "password")
CoreConnectionString.DATABASE = appConfig.get("CoreContext", "database")



pymssql.connect(host=objdeltaxConnectionString.HOST, user=objdeltaxConnectionString.USER,password=objdeltaxConnectionString.PASSWORD, database=objdeltaxConnectionString.DATABASE)
