IMAP呼叫Gmail期间出现“ SELECT命令错误错误”

Question

I want to get G-mail with Google account by using IMAP. So I found some basic code how to use IMAP. And I run it with my Google account. But I get some errors. I don't know role of functions or parameters so please help me if you have gmail account and know the role of functions.

This is my code and I conceal my account information so the real account is different to mine.

#!/usr/bin/env python

import sys
import imaplib
import getpass
import email
import email.header
import datetime
EMAIL_ACCOUNT = "id@gmail.com"
EMAIL_PASSWORD = "password"
# Use 'INBOX' to read inbox.  Note that whatever folder is specified,
# after successfully running this script all emails in that folder
# will be marked as read.
EMAIL_FOLDER = "Top Secret/PRISM Documents"
def process_mailbox(M):

rv, data = M.search(None, "ALL")
if rv != 'OK':
    print("No messages found!")
    return
    for num in data[0].split():
        rv, data = M.fetch(num, '(RFC822)')
        if rv != 'OK':
            print("ERROR getting message", num)
            return
        msg = email.message_from_bytes(data[0][1])
        hdr = 
        email.header.make_header(email.header.decode_header(msg['Subject']))
        subject = str(hdr)
        print('Message %s: %s' % (num, subject))
        print('Raw Date:', msg['Date'])
        # Now convert to local date-time
        date_tuple = email.utils.parsedate_tz(msg['Date'])
        if date_tuple:
            local_date = datetime.datetime.fromtimestamp(
                email.utils.mktime_tz(date_tuple))
            print ("Local Date:", \
                local_date.strftime("%a, %d %b %Y %H:%M:%S"))
M = imaplib.IMAP4_SSL('imap.gmail.com')
try:
    rv, data = M.login(EMAIL_ACCOUNT, EMAIL_PASSWORD)
except imaplib.IMAP4.error:
    print ("LOGIN FAILED!!! ")
    sys.exit(1)
print(rv, data)
rv, mailboxes = M.list()
if rv == 'OK':
    print("Mailboxes:")
    print(mailboxes)
rv, data = M.select(EMAIL_FOLDER)
if rv == 'OK':
    print("Processing mailbox...\n")
    process_mailbox(M)
    M.close()
else:
    print("ERROR: Unable to open mailbox ", rv)
M.logout()

This is the error result.

This is errors in text.

Answer 1

The call to

M.select(EMAIL_FOLDER)

isn't including any of the mailboxes returned from:

rv, mailboxes = M.list()

---

Ensure that the mailbox name is valid.
