python smtplib 發送郵件簡單介紹

SMTP（Simple Mail Transfer Protocol）即簡單郵件傳輸協議,它是一組用於由源地址到目的地址傳送郵件的規則，由它來控制信件的中轉方式
python的smtplib提供了一種很方便的途徑發送電子郵件。它對smtp協議進行了簡單的封裝。

Python建立 SMTP 對象語法:
　　import smtplib
　　smtpObj = smtplib.SMTP( [host [, port [, local_hostname]]] )

參數說明：
　　host: SMTP 服務器主機。 你能夠指定主機的ip地址或者域名如: runoob.com，這個是可選參數。
　　port: 若是你提供了 host 參數, 你須要指定 SMTP 服務使用的端口號，通常狀況下 SMTP 端口號爲25。
　　local_hostname: 若是 SMTP 在你的本機上，你只須要指定服務器地址爲 localhost 便可。

Python SMTP 對象使用 sendmail 方法發送郵件，語法以下:
　　SMTP.sendmail(from_addr, to_addrs, msg[, mail_options, rcpt_options]

參數說明：
　　from_addr: 郵件發送者地址。
　　to_addrs: 字符串列表，郵件發送地址。
　　msg: 發送消息

 

# 使用163郵箱給本身發郵件信息

import smtplib

from email.header import Header

mail_pass = "aaaaaa"

sender = "aaaaa@163.com"
receivers = ["aaaaaa@163.com"]

message = MIMEText("python 郵件測試","plain","utf-8")
message["From"] = Header("ceshi","utf-8")
message["To"] = Header("CESHI","UTF-8")

subject = "python semp email ceshi ...."

try:
    smtpOBJ = smtplib.SMTP()
    smtpOBJ.connect(mail_host, 25)
    smtpOBJ.login(mail_user,mail_pass)
    smtpOBJ.sendmail(sender,receivers,message.as_string())
except smtplib.SMTPException:
    print("error")

　　

# 使用163郵箱發送信息，帶附件

import smtplib

from email.mime.multipart import MIMEMultipart
from email.header import Header

try:

# 使用163郵箱發送信息，帶附件和html

在 HTML 文本中添加圖片
郵件的 HTML 文本中通常郵件服務商添加外鏈是無效的，正確添加突破的實例以下所示：

import smtplib
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.header import Header

mail_host = "smtp.163.com"
mail_user = "15800220134@163.com"
mail_pass = "abc115698"

sender = "15800220134@163.com"
receivers = ["15800220134@163.com"]

msgRoot = MIMEMultipart("related")
msgRoot["From"] = Header("wo")
msgRoot["To"] = Header("ni")
subject = "Python SMTP 郵件測試,html + 圖片"
msgRoot["Subject"] = Header(subject,"utf-8")

msgAlternative = MIMEMultipart("alternative")
msgRoot.attach(msgAlternative)

mail_msg = """
<p>Python 郵件發送測試...</p>
<p><a href="http://www.runoob.com">菜鳥教程連接</a></p>
<p>圖片演示：</p>
<p><img src="cid:image1"></p>
"""
msgAlternative.attach(MIMEText(mail_msg, 'html', 'utf-8'))

fb = open("1111.jpg","rb")
msgImage = MIMEImage(fb.read())
fb.close()

msgImage.add_header('Content-ID', '<image1>')
msgRoot.attach(msgImage)

try:
    smtpOBJ = smtplib.SMTP()
    smtpOBJ.connect(mail_host, 25)
    smtpOBJ.login(mail_user,mail_pass)
    smtpOBJ.sendmail(sender,receivers,msgRoot.as_string())
except smtplib.SMTPException:
    print("error")

　　

# 驗證開通郵箱的smtp協議的受權碼，並驗證登陸

驗證代碼：

import smtplib
from email.mime.text import MIMEText

server = smtplib.SMTP("smtp.163.com",25)
server.login("aaaaaa@163.com","aaaaaa")
MSG = MIMEText("hello,send by python..","plain","utf-8")
server.sendmail("aaaaaa@163.com",["aaaaaaa@163.com"],MSG.as_string())
