python 中 imaplib 的错误处理

Question

当我使用这一行时：

m = imaplib.IMAP4("some host")

我收到此错误：

 m = imaplib.IMAP4("some host")
  File "C:\Python25\lib\imaplib.py", line 163, in __init__
    self.open(host, port)
  File "C:\Python25\lib\imaplib.py", line 230, in open
    self.sock.connect((host, port))
  File "<string>", line 1, in connect
error: (10061, 'Connection refused')

如何对此错误进行错误处理？

Answer 1

使用标准 try/ except 块：

import socket

try:
    m = imaplib.IMAP4("some host")
except socket.error, e:
    print "Error opening IMAP connection: ", e
