我有 config.ini:
[mysql]
host=localhost
port=3306
user=root
passwd=abcdefgh
db=testdb
unix_socket=/opt/lampp/var/mysql/mysql.sock
我有这门课:
#!/usr/bin/python
import MySQLdb,ConfigParser
config = ConfigParser.ConfigParser()
config.read("config.ini")
class MySQL( object ):
def __init__( self ):
self.host = config.get("mysql","host")
self.port = config.get("mysql","port")
self.user = config.get("mysql","user")
self.passwd = config.get("mysql","passwd")
self.db = config.get("mysql","db")
self.unix_socket = config.get("mysql","unix_socket")
self.conn = MySQLdb.Connect(self.host,
self.port,
self.user,
self.passwd,
self.db,
self.unix_socket)
self.cursor = self.conn.cursor ( MySQLdb.cursors.DictCursor )
def __del__( self ):
self.cursor.close()
self.conn.close()
还有这个:
#!/usr/bin/env python
from mysql import MySQL
class Incident( MySQL ):
def getIncidents( self ):
self.cursor.execute("""*VALID QUERY*""")
return self.cursor.fetchall()
最后是这个:
import subprocess, os, alarm
from Queue import Queue
from incident_model import Incident
fileQueue = Queue()
def enumerateFilesPath():
global fileQueue
incident = Incident()
incidents = incident.getIncidents()
for i in incidents:
fileQueue.put("MD5")
def main():
global fileQueue
enumerateFilesPath()
输出:
Traceback (most recent call last):
File "./mwmonitor.py", line 202, in
main() File "./mwmonitor.py", line 184, in main
enumerateFilesPath() File "./mwmonitor.py", line 86, in

如果有人可以帮助检测和纠正错误,将不胜感激。 提前致谢。
最佳答案
您的 __del__
方法引起了混淆。具体来说,它指的是 self.cursor
和 self.conn
,如果 MySQLdb.Connect
引发异常(这似乎是发生了什么)。
我建议你修改你的类如下:
class MySQL( object ):
def __init__( self ):
self.conn = None
self.cursor = None
self.host = config.get("mysql","host")
self.port = config.get("mysql","port")
self.user = config.get("mysql","user")
self.passwd = config.get("mysql","passwd")
self.db = config.get("mysql","db")
self.unix_socket = config.get("mysql","unix_socket")
self.conn = MySQLdb.Connect(self.host,
self.port,
self.user,
self.passwd,
self.db,
self.unix_socket)
self.cursor = self.conn.cursor ( MySQLdb.cursors.DictCursor )
def __del__( self ):
if self.cursor is not None:
self.cursor.close()
if self.conn is not None:
self.conn.close()
这不会解决问题,但应该提供更好的诊断。
现在谈谈您遇到的实际问题。我强烈怀疑您以错误的顺序向 Connect
提供了参数,或者类型不太正确,或者类似的东西。引用 Connection.__init__
的文档字符串:
Create a connection to the database. It is strongly recommended
that you only use keyword parameters. Consult the MySQL C API
documentation for more information.
host
string, host to connect
user
string, user to connect as
passwd
string, password to use
db
string, database to use
port
integer, TCP/IP port to connect to
unix_socket
string, location of unix_socket to use
...
“强烈建议您仅使用关键字参数。”我建议您在调用 MySQLdb.Connect
时就这样做。此外,请确保 port
是 int
而不是字符串。
