python - “str”对象没有属性 'message_from_bytes'

Question

我有一段代码可以从我的收件箱(gmail)的消息中获取电子邮件。当我打印 email_from 时，电子邮件工作正常，但我想对数据拆分名称和电子邮件等进行一些操作，但在打印第一个循环步骤后代码中断，我收到错误:

Traceback (most recent call last):
  File "C:\Users\loc\Desktop\extract_gmail.py", line 24, in <module>
    email_message_raw = email.message_from_bytes(data[0][1])
AttributeError: 'str' object has no attribute 'message_from_bytes'

你能给我一些如何解决这个问题的建议吗？

代码:

import imaplib
import email
from email.header import Header, decode_header, make_header

# Connection settings
HOST = 'imap.gmail.com'
USERNAME = '***'
PASSWORD = '***'

m = imaplib.IMAP4_SSL(HOST, 993)
m.login(USERNAME, PASSWORD)
m.select('INBOX')

result, data = m.uid('search', None, "ALL")
if result == 'OK':
    for num in data[0].split()[:5]:
        result, data = m.uid('fetch', num, '(RFC822)')
        if result == 'OK':
            # Get raw message
            email_message_raw = email.message_from_bytes(data[0][1])

            # Decode headers
            email_from = str(make_header(decode_header(email_message_raw['From'])))

            # Print each name and email
            name, email = email_from.split('<')
            email.replace(">", "")
            print(name + "|" + email)

            # When i swap to just print email_from then works
            # print(email_from)



# Close server connection
m.close()
m.logout()

在您的代码中，您替换了电子邮件变量..

试试这个...

import imaplib
import email
from email.header import Header, decode_header, make_header

# Connection settings
HOST = 'imap.gmail.com'
USERNAME = '***'
PASSWORD = '***'

m = imaplib.IMAP4_SSL(HOST, 993)
m.login(USERNAME, PASSWORD)
m.select('INBOX')

result, data = m.uid('search', None, "ALL")
if result == 'OK':
    for num in data[0].split()[:5]:
        result, data = m.uid('fetch', num, '(RFC822)')
        if result == 'OK':
            # Get raw message
            email_message_raw = email.message_from_bytes(data[0][1])

            # Decode headers
            email_from = str(make_header(decode_header(email_message_raw['From'])))

            # Print each name and email
            name, email_addr = email_from.split('<')
            email_addr.replace(">", "")
            print(name + "|" + email_addr)

            # When i swap to just print email_from then works
            # print(email_from)



# Close server connection
m.close()
m.logout()
