Question

如何解析包含特定名称文件的电子邮件，我无法使用 SUBJECT 进行解析，因为它是空的

Answer 1

我还没有对此进行测试，但如果它有一个具有您指定名称的文件，它应该打印邮件 ID。

import imaplib
import email

file_name = ""
server_outgoing = ""
username = ""
password = ""

connection = imaplib.IMAP4_SSL(server_outgoing)
connection.login(username, password)

connection.select("inbox")
status, mail_datas = connection.search(None, 'ALL')

mail_ids = []
for mail_data in mail_datas:
    mail_ids += mail_data.split()

for mail_id in mail_ids:
    status, data = connection.fetch(mail_id, '(RFC822)')
    message = email.message_from_bytes(data[0][1])

    if message.is_multipart():
        for part in message.get_payload():
            filename = part.get_filename()
            if(filename == file_name):
                print(mail_id)
