Python实例之接收邮件的代码

发布时间:2020-09-30编辑:脚本学堂
分享几个python接收邮件的代码,学习下python中实现邮件接收的方法,有需要的朋友参考下。

1,主要使用了 poplib 组件
 

复制代码 代码示例:
# -*- 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
 

复制代码 代码示例:
# -*- 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" 
 

安装很简单,点击 showpythonPath.bat 测试一下环境,然后复制 _chilkat.pyd 和 chilkat.py 到 Python27Libsite-packages 下即可。
 
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
 

复制代码 代码示例:
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('MESSAGESs+(d+)',y[0]).group(1)) 
                unseen=int(re.search('UNSEENs+(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
 

复制代码 代码示例:
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()
