imaplib-將郵件移動到檔案夾失敗且沒有錯誤日志

我的 python 代碼選擇了一些郵件并將它們移動到另一個檔案夾。

# A.py

    def __init__(self):
        account = conf.account
        password = conf.password
        server = conf.imap_server
        port = conf.imap_port
        self.mail = imaplib.IMAP4_SSL(host=server, port=port)
        try:
            self.mail.login(account, password)
        except imaplib.IMAP4.error as e:
            self.logger.error("Cannot login to STMP server: %s" % str(e))


    def move_handled_mails(self, mail_list, suffix=0):
        archiving_folder = ''.join([str(current_year), '-', str(current_month), '-', str(suffix)])
        self.mail.debug = 4
        typ, data = self.mail.select(archiving_folder)
        if typ != 'OK':
            if "NONEXISTENT" in data[0].decode():
                self.mail.create(archiving_folder)
                typ, data = self.mail.select(archiving_folder)
            if "Too many mail in folder" in data[0].decode():
                return self.move_handled_mails(mail_list, suffix 1)

        if typ != 'OK':
            exit()

        for num in mail_list:
            print(num)
            typ, data = self.mail.uid('COPY', num, archiving_folder)
            if typ == 'OK':
                typ, data = self.mail.uid('STORE', num, ' FLAGS', '(\\Deleted)')
            if typ != 'OK':
                exit()
        print("Executing expunge")
        typ, data = self.mail.expunge()
        if typ != 'OK':
            exit()


    def run(self):
        res, nums = self.mail.select()  # default=INBOX
        if res != 'OK':
            self.logger.error(nums)
            exit()

        typ, msgnums = self.mail.uid('search', None, 'ALL')
        mail_list = msgnums[0].split()
        self.move_handled_mails(mail_list)

在該move_handled_mails方法中，創建檔案夾效果很好，但移動郵件不起作用。

此外，當我列印所有typS和dataS，它們被列印為OK和Nonerepectively。

運行代碼后，沒有發生錯誤，但也沒有移動郵件。

什么可能是問題，我應該如何除錯這個問題？

添加后除錯日志self.mail.debug=4：

  03:12.87 > b'GBDI2 SELECT 2021-11-0'
  03:13.04 < b'* FLAGS (\\Answered \\Flagged \\Deleted \\Seen \\Draft)'

uj5u.com熱心網友回復：

不要select移動到檔案夾。 UIDs 僅在其源檔案夾中有意義。您正在切換到目標檔案夾，然后嘗試將郵件移出其中，但該郵件不存在。

洗掉這一行： typ, data = self.mail.select(archiving_folder)

或者，至少，如果您需要它來檢查目標檔案夾是否存在，您必須切換回源檔案夾：self.mail.select('INBOX')或類似的。
