Python实例讲解 -- 接收邮件 (亲测)

renshanshan

1. 主要使用了 poplib 组件

# -*- coding: utf-8 -*-  
import poplib  
from email import parser  
host = 'pop.gmail.com'  
username = 'mine@gmail.com'  
password = '*******'  
pop_conn = poplib.POP3_SSL(host)  
pop_conn.user(username)  
pop_conn.pass_(password)  
#Get messages from server:  
messages = [pop_conn.retr(i) for i in range(1, len(pop_conn.list()[1]) + 1)]  
# Concat message pieces:  
messages = ["\n".join(mssg[1]) for mssg in messages]  
#Parse message intom an email object:  
messages = [parser.Parser().parsestr(mssg) for mssg in messages]  
for message in messages:  
print message['Subject']  
pop_conn.quit()  


优点： 可以输出内容
缺点： 只检测一次
2. 使用第三方插件 chilkat

# -*- coding: utf-8 -*-  
import sys  
import chilkat  
host = 'pop.gmail.com'  
username = 'mine@gmail.com'  
password = '******'  
# The mailman object is used for receiving (POP3)  
# and sending (SMTP) email.  
mailman = chilkat.CkMailMan()  
# Any string argument automatically begins the 30-day trial.  
success = mailman.UnlockComponent("30-day trial")  
if (success != True):  
print "Component unlock failed"  
sys.exit()  
# Set the GMail account POP3 properties.  
mailman.put_MailHost(host)  
mailman.put_PopUsername(username)  
mailman.put_PopPassword(password)  
mailman.put_PopSsl(True)  
mailman.put_MailPort(995)  
# Read mail headers and one line of the body.  
# To get the full emails, call CopyMail instead (no arguments)  
bundle = mailman.GetAllHeaders(1)  
if (bundle == None ):  
print mailman.lastErrorText()  
sys.exit()  
for i in range(0,bundle.get_MessageCount()):  
email = bundle.GetEmail(i)  
# Display the From email address and the subject.  
print email.ck_from()  
print email.subject() + "\n"


安装见附件
主页：http://www.chilkatsoft.com/products.asp
安装：http://www.chilkatsoft.com/installPython27.asp
安装很简单，点击 showPythonPath.bat 测试一下环境，然后复制 _chilkat.pyd 和 chilkat.py 到 Python27\Lib\site-packages\ 下就可以
优点： 可以多次检测
缺点： 只可以看到来源和主题，无法看到内容
3. 检测邮件，返回未读数值

def gmail_checker(username,password):  
import imaplib,re  
i=imaplib.IMAP4_SSL('pop.gmail.com')  
try:  
i.login(username,password)  
x,y=i.status('INBOX','(MESSAGES UNSEEN)')  
messages=int(re.search('MESSAGES\s+(\d+)',y[0]).group(1))  
unseen=int(re.search('UNSEEN\s+(\d+)',y[0]).group(1))  
return (messages,unseen)  
except:  
return False,0  
# Use in your scripts as follows:  
messages,unseen = gmail_checker('mine@gmail.com','******')  
print "%i messages, %i unseen" % (messages,unseen)  


4. 很好的返回主题和内容

import imaplib  
import email  
def extract_body(payload):  
if isinstance(payload,str):  
return payload  
else:  
return '\n'.join([extract_body(part.get_payload()) for part in payload])  
conn = imaplib.IMAP4_SSL("pop.gmail.com", 993)  
conn.login("mine@gmail.com", "******")  
conn.select()  
typ, data = conn.search(None, 'UNSEEN')  
try:  
for num in data[0].split():  
typ, msg_data = conn.fetch(num, '(RFC822)')  
for response_part in msg_data:  
if isinstance(response_part, tuple):  
msg = email.message_from_string(response_part[1])  
subject=msg['subject']                     
print(subject)  
payload=msg.get_payload()  
body=extract_body(payload)  
print(body)  
typ, response = conn.store(num, '+FLAGS', r'(\Seen)')  
finally:  
try:  
conn.close()  
except:  
pass  
conn.logout()
