imaplib.error：命令 SEARCH 在 AUTH 状态下非法，仅在 SELECTED 状态下允许

Question

def connect_imap():
    m = imaplib.IMAP4_SSL("imap.gmail.com", 993)
    print("{0} Connecting to mailbox via IMAP...".format(datetime.datetime.today().strftime("%Y-%m-%d %H:%M:%S")))
    details = login_credentials()
    m.login(details[0], details[1])
    return m


m = connect_imap()
typ, data = m.search(None, 'ALL')
m.close()
m.logout()

上述代码的输出是：

2016-08-24 10:55:34 Connecting to mailbox via IMAP...
    Traceback (most recent call last):
      File "/home/zoikmail/Desktop/test.py", line 25, in <module>
        typ, data = m.search(None, 'ALL')
      File "/usr/lib/python2.7/imaplib.py", line 640, in search
        typ, dat = self._simple_command(name, *criteria)
      File "/usr/lib/python2.7/imaplib.py", line 1088, in _simple_command
        return self._command_complete(name, self._command(name, *args))
      File "/usr/lib/python2.7/imaplib.py", line 838, in _command
        ', '.join(Commands[name])))
    imaplib.error: command SEARCH illegal in state AUTH, only allowed in states SELECTED

上面的代码有什么问题？

Answer 1

成功连接到IMAP服务器后，您需要选择一个邮箱。 使用

m.select()

连接后、搜索前。

Answer 2

首先你需要使用该功能：

imap.select("INBOX")

之后您可以使用带有 imap.uid 的命令进行搜索。基本上，当您使用 imap.select 时，您会正确连接到邮件服务器。
