使用Python和poplib获取电子邮件 [英] Get emails with Python and poplib

问题描述

我想使用Python登录我的帐户，并让python打印我在邮箱中收到的邮件。我知道如何连接

I would like to log into my account with Python and get python to print the messages I received in my mailbox. I know how to connect

import getpass, poplib
user = 'my_user_name' 
Mailbox = poplib.POP3_SSL('pop.googlemail.com', '995') 
Mailbox.user(user) 
Mailbox.pass_('my_password') 

我不知道如何让Python显示我的消息。我尝试了poplib文档中的所有功能。它们只显示数字。

I don't know how to get Python to display my messages. I tried all the functions in the poplib doc. They only display numbers.

推荐答案

您尚未发布源代码，但这里是我的回复：

You have not posted your source code, but here is my response:

如何获取消息总数：

(numMsgs, totalSize) = self.conn_pop3.stat()

如何获取特定邮件，知道邮箱中的号码：

(server_msg, body, octets) = self.conn_pop3.retr(number)

所以您可能需要的功能是 retr ，它返回一个元组。
请参阅
此处。

So the function you might need is retr, it returns a tuple. See here.

小心它还将相应的电子邮件设置为服务器上的SEEN！
你可以撤消这个，至少用IMAP你可以。

Careful it also sets the respective email as SEEN on the server! You can probably undo that, at least with IMAP you can.

我的一个pop3 lib电子邮件的实现读取：

And my implementation of a pop3 lib email read:

from poplib  import POP3
...
    if self.pop3_connected:            
        try:
            #------Check if email number is valid----------------------
            (numMsgs, totalSize) = self.conn_pop3.stat()
            self.debug(200, "Total number of server messages:    ", numMsgs)                
            self.debug(200, "Total size   of server messages:    ", totalSize)
            if  number>numMsgs:
                self.debug(200, "\nSorry - there aren't that many messages in your inbox\n")
                return False
            else:
                (server_msg, body, octets) = self.conn_pop3.retr(number)
                self.debug(200, "Server Message:    "   , server_msg)
                self.debug(200, "Number of Octets:    " , octets)
                self.debug(200, "Message body:")
                for line in body:
                    print line
                #end for
                return True
            #endif
        finally:
            self.__disconnect__()      
    #endif 

另外这里是POP3连接，至少我如何实现它...使用字符串比较有点棘手，但它适用于我的应用程序：

Also here is the POP3 connection, at least how I implemented it...sort of tricky using a string comparison, but it worked for my app:

def __connect_pop3__(self):
    """\brief Method for connecting to POP3 server                        
       \return True   If connection to POP3 succeeds or if POP3 is already connected
       \return False  If connection to POP3 fails
    """
    #------Check that POP3 is not already connected-----------------------
    if not self.pop3_connected:
        #------Connect POP3-----------------------------------------------
        self.debug(100, 'Connecting POP3 with: ', self.host_name, self.user_name, self.pass_name)
        self.conn_pop3 = POP3(self.host_name)            
        res1 = self.conn_pop3.user(self.user_name)
        string1 = str(res1)      
        self.debug(100, 'User identification result:', string1) 
        res2 = self.conn_pop3.pass_(self.pass_name)        
        string2 = str(res2)                
        self.debug(100, 'Pass identification result:', string2)                        
        #------Check if connection resulted in success--------------------
        #------Server on DavMail returns 'User successfully logged on'----
        if  string2.find('User successfully logged on')<>-1 or string1.find('User successfully logged on')<>-1 :
            self.pop3_connected = True            
            return True
        else:
            return False
        #endif         
    else:       
        self.debug(255, 'POP3 already connected')
        return True
    #endif
