如何使用 python imaplib 閱讀電子郵件

Question

我正在創建一個 email 系統來讀取電子郵件並向用戶顯示它們是什么。

我所擁有的代碼無法正常顯示內容。 我知道有些電子郵件使用 html 格式，所以想知道是否是這種情況。 無論哪種方式，我都需要幫助將其轉換為可讀格式，最好看起來像原始格式。

我得到了 output

我的代碼是：

import email
import imaplib

mail = imaplib.IMAP4_SSL(SERVER)
mail.login(EMAIL, PASSWORD)
mail.select('inbox')


status, data = mail.search(None, 'ALL')

mail_ids = []

for block in data:
    mail_ids += block.split()

for i in mail_ids:
    status, data = mail.fetch(i, '(RFC822)')

    for response_part in data:
        if isinstance(response_part, tuple):
            message = email.message_from_bytes(response_part[1])

            mail_from = message['from']
            mail_subject = message['subject']

            if message.is_multipart():
                mail_content = ''
                for part in message.get_payload():
                    if part.get_content_type() == 'text/plain':
                        mail_content += part.get_payload()
            else:
                mail_content = message.get_payload()

            print(f'From: {mail_from}')
            print(f'Subject: {mail_subject}')
            print(f'Content: {mail_content}')

那么有什么辦法可以讓它變成可讀的格式嗎？

Answer 1

內容（在這種情況下）是 base64 編碼的。 你會想要

1. 確定內容的編碼，因為它可能使用不同的編碼，
2. 導入相應的模塊，如 base64 或 uu，然后，
3. 從模塊上調用解碼 function 對編碼的內容。

對於#1，在完整的消息內容中可能還有另一個 header 指示使用的編碼。

Answer 2

import base64
print(base64.b64decode(mail_content))
