使用Python和poplib获取电子邮件

Question

我想用Python登录我的帐户并使用python打印我在邮箱中收到的邮件.我知道如何连接

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 doc中的所有函数.它们只显示数字.

Answer 1

使用文档中的POP3示例:

import getpass, poplib
user = 'my_user_name' 
Mailbox = poplib.POP3_SSL('pop.googlemail.com', '995') 
Mailbox.user(user) 
Mailbox.pass_('my_password') 
numMessages = len(Mailbox.list()[1])
for i in range(numMessages):
    for msg in Mailbox.retr(i+1)[1]:
        print msg
Mailbox.quit()

Answer 2

您尚未发布源代码,但这是我的回复:

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)

所以你可能需要的函数是retr,它返回一个元组.看到 这里.

小心它还将相应的电子邮件设置为服务器上的SEEN!您可以撤消这一点,至少可以使用IMAP.

我的pop3 lib电子邮件的实现读取:

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,至少我是如何实现它的...使用字符串比较有点棘手,但它适用于我的应用程序:

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
