python smtplib 携带附件 python smtplib发送邮件

本文针对QQ邮箱的邮件发送，163邮箱与之类似

1. 首先应在邮箱中开启SMTP 服务并获得授权码：

在开启了SMTP 服务之后我们会获得授权码（授权码可有多个，均可正常使用）：

2. 使用Python3 发送简单邮件

Python对SMTP 支持有smtplib 和email 两个模块，email 负责构造邮件，smtplib 负责发送邮件

# --coding: UTF-8--
import smtplib
from email.header import Header          # 用来设置邮件头和邮件主题
from email.mime.text import MIMEText     # 发送正文只包含简单文本的邮件，引入MIMEText即可

def send_email(sender_email, reciver_email, authorization_code, smtp_server, email_title, email_body):

	message = MIMEText(email_body, 'plain', 'utf-8')   # 邮件正文，'plain'表示纯文本，'utf-8'保证多语言兼容性
	message['From'] = sender_email                     # 邮件上显示的发件人
	message['To'] = reciver_email                      # 邮件上显示的收件人
	message['Subject'] = Header(email_title, 'utf-8')  # 邮件主题
	 
	try:
	    smtp = smtplib.SMTP()                           # 创建一个连接
	    smtp.connect(smtp_server)                       # 连接发送邮件的服务器
	    smtp.login(sender_email, authorization_code)    # 登录服务器
	    smtp.sendmail(sender_email, reciver_email, message.as_string())  # 填入邮件的相关信息并发送
	    print("邮件发送成功！！！")
	    smtp.quit()
	except smtplib.SMTPException:
	    print("邮件发送失败！！！")

title = 'Test'
body = 'This is a test'
send_email('[e-mail]', '[e-mail]', 'ickdbbikbbXXXXXX', 'smtp.qq.com', title, body)

代码参数说明：

参数	说明
sender_email	发件人邮箱
reciver_email	收件人邮箱
authorization_code	授权码
smtp_server	SMTP 服务器地址
email_title	邮件主题
email_body	邮件正文

邮件发送结果：

若将代码第13 行修改为smtp = smtplib.SMTP_SSL() 可实现SSL 加密，虽然我并不觉得有什么不同…

顺便补充一下：

网易STMP 服务器和端口	QQ STMP 服务器和端口
465	465

3. 邮件多发

将上述代码中最后函数的调用改一改：

send_email('[e-mail]', '[e-mail]', 'ickdbbikbbXXXXXX', 'smtp.qq.com', title, body)

改为 👇

send_email('[e-mail]', ['[e-mail]', '[e-mail]'], 'ickdbbikbbXXXXXX', 'smtp.qq.com', title, body)

收件人邮箱由单个变为列表，将收件人由单个变为多个。

4. 发送文件

# --coding: UTF-8--
import smtplib
from email.header import Header          # 用来设置邮件头和邮件主题
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText     # 发送正文只包含简单文本的邮件，引入MIMEText即可
from email.mime.image import MIMEImage
from datetime import datetime


def send_email(sender_email, reciver_email, authorization_code, smtp_server, email_title, email_body):
    # message = MIMEText(email_body, 'plain', 'utf-8')   # 邮件正文，'plain'表示纯文本，'utf-8'保证多语言兼容性
    message = MIMEMultipart('related')
    message['From'] = sender_email                     # 邮件上显示的发件人
    message['To'] = reciver_email                      # 邮件上显示的收件人
    message['Subject'] = Header(email_title, 'utf-8')  # 邮件主题

    fp = open('C:/xxxx/Desktop/PeopleInHouse.jpg', 'rb')
    msgImage = MIMEImage(fp.read())
    fp.close()
    msgImage.add_header('Content-ID', '')
    message.attach(msgImage)

    try:
        smtp = smtplib.SMTP()                           # 创建一个连接
        smtp.connect(smtp_server)                       # 连接发送邮件的服务器
        smtp.login(sender_email, authorization_code)    # 登录服务器
        smtp.sendmail(sender_email, reciver_email, message.as_string())  # 填入邮件的相关信息并发送
        print("邮件发送成功！！！")
        smtp.quit()
    except smtplib.SMTPException:
        print("邮件发送失败！！！")

Now_Time = str(datetime.now()).split(" ")[1]
Hour = Now_Time.split(":")[0]
Minute = Now_Time.split(":")[1]
Second = Now_Time.split(":")[2].split(".")[0]

title = '入侵警告'
body = "警告！有人于" + Hour + "时" + Minute + "分" + Second + "秒闯入家中"
sender_email = '[e-mail]'
reciver_email = '[e-mail]'
code = 'xxxxx'
server_name = 'smtp.qq.com'
send_email(sender_email, reciver_email, code, server_name, title, body)

文件会以二进制数据形式发送出去，也就是.bin 格式

5. 发送附件

# --coding: UTF-8--
import smtplib
from email.header import Header          # 用来设置邮件头和邮件主题
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText     # 发送正文只包含简单文本的邮件，引入MIMEText即可
from email.mime.image import MIMEImage
from datetime import datetime


def send_email(sender_email, reciver_email, authorization_code, smtp_server, email_title, email_body):
    # message = MIMEText(email_body, 'plain', 'utf-8')   # 邮件正文，'plain'表示纯文本，'utf-8'保证多语言兼容性
    message = MIMEMultipart('related')
    message['From'] = sender_email                     # 邮件上显示的发件人
    message['To'] = reciver_email                      # 邮件上显示的收件人
    message['Subject'] = Header(email_title, 'utf-8')  # 邮件主题

    att = MIMEText(open('C:/xxxxx/Desktop/PeopleInHouse.jpg', 'rb').read(), 'base64', 'utf-8')  
    att["Content-Type"] = 'application/octet-stream'  
    att["Content-Disposition"] = 'attachment; filename="PeopleInHouse.jpg"'
    message.attach(att)

    try:
        smtp = smtplib.SMTP()                           # 创建一个连接
        smtp.connect(smtp_server)                       # 连接发送邮件的服务器
        smtp.login(sender_email, authorization_code)    # 登录服务器
        smtp.sendmail(sender_email, reciver_email, message.as_string())  # 填入邮件的相关信息并发送
        print("邮件发送成功！！！")
        smtp.quit()
    except smtplib.SMTPException:
        print("邮件发送失败！！！")


Now_Time = str(datetime.now()).split(" ")[1]
Hour = Now_Time.split(":")[0]
Minute = Now_Time.split(":")[1]
Second = Now_Time.split(":")[2].split(".")[0]

title = "警告！有人于" + Hour + "时" + Minute + "分" + Second + "秒闯入家中"
body = "警告！有人于" + Hour + "时" + Minute + "分" + Second + "秒闯入家中"
sender_email = '[e-mail]'
reciver_email = '[e-mail]'
code = 'xxxxx'
server_name = 'smtp.qq.com'
send_email(sender_email, reciver_email, code, server_name, title, body)
