python3通過pop3下載郵件並對其進行處理

Question

我通過電子郵件發送打印機狀態報告。我想下載它們並逐個處理，並將所有信息放入某個數據庫中作進一步處理。 我想使用python3，因爲我開始學習它。 我有這樣的代碼：

import getpass 
import poplib 

server = poplib.POP3('pop3.mailserver.com') 

server.user('report@mailserver.com') 
server.pass_('pswd') 

numMessages = 1 #len(server.list()[1]) 
emails, total_bytes = server.stat() 

print("{0} emails in the inbox, {1} bytes total".format(emails, total_bytes)) 

for i in range(numMessages): 
    for msg in server.retr(i+1)[1]: 
     print(msg) 

和我所得到的是整個電子郵件消息（與標題和正文）的格式如下：

b'Delivered-To: reportc@mailserver.com'

我需要的是通過線處理主體內容線如果匹配，我需要從服務器上刪除它。

和提示如何做到這一點？

Answer 1

也許，如果你通過分析這將是一個良好的開端消息開始：

# ... get your message ... 
# msg = [b'Return-Path: <"tever">' 
#  b'Delivered-To: reportc@mailserver.com', ... ] 

import email 

# decode simple non-multipart message 
message = email.message_from_bytes(b'\n'.join(msg)) 
payload = message.get_payload(decode=True) 
payload = payload.decode(message.get_content_charset()) 
print(payload) 

那麼你可以用任何你需要的有效載荷做...
