模块：email、smtplib

# Python发送邮件
## 功能需求
1. 使用smtplib, email两个模块
2. 可以同时发送文本与附件
3. 账号使用企业邮箱账号(注意不要把自己的账号写到wiki上)

## 提示信息
1. 需要引入的模块及类
```python
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.utils import formataddr
```
2. python帮助使用方式
引入模块后,可以使用help()来查看帮助.例如:
```python
import smtplib
help(smtplib)
```
## 实操 文本

import smtplib
	import csv
	from email.mime.text import MIMEText
	from email.header import Header

from email.mime.text import MIMEText #文本（plain，html格式）
	from email.mime.image import MIMEImage #（附件图片）
	from email.mime.multipart import MIMEMultipart #（超文本，都行）
	from_addr = '740774622@qq.com'
	to_addrs = ['935523993@qq.com','740774622@qq.com']
	to_addr = []
	date = [['zw','935523993@qq.com'],['hmb','740774622@qq.com']]
	with open('/Users/huangmingbin/Desktop/to_addrs.csv','w',newline='') as f:
		writer = csv.writer(f)
		for row in date:
			writer.writerow(row)
	with open('/Users/huangmingbin/Desktop/to_addrs.csv','r',newline='') as b:
		reader = csv.reader(b)
		for row in reader:
			to_addr = row[1]
	password = 'zygwkyrktdiybcda'
	smtp_server = 'smtp.qq.com'
	test = '''
	人生苦短，我用Python
	人生苦短，我用Python
	'''
	msg = MIMEText(test,'plain','utf-8')

msg['From'] = Header('Redhat')
	msg['To'] = Header(",".join(to_addrs))
	msg['Subject'] = Header('Nice to me you ')

server = smtplib.SMTP_SSL(smtp_server)
	server.connect(smtp_server,465) #连接smtp服务器
	server.login(from_addr, password) #登录
	try:
		server.sendmail(from_addr, to_addrs, msg.as_string()) #发送
		print("successd")
	except:
		print("faild")
	server.quit() #退出
```

## 实操2  如何带附件，图片
	import smtplib
	from email.mime.text import MIMEText
	from email.mime.image import MIMEImage
	from email.mime.multipart import MIMEMultipart

from_addr = '740774622@qq.com'
	to_addr = '740774622@qq.com'
	password = 'xxxxx' #自己的授权码
	smtp_server = 'smtp.qq.com'

msg = MIMEMultipart('related')

msg['From'] = from_addr
	msg['To'] = to_addr
	msg['Subject'] = 'Nice to me you'

with open(r'/Users/huangmingbin/Desktop/proc.doc', 'rb') as p:
		text = MIMEText(p.read(),'base64','utf-8')
		#test["Content-Type"] = 'application/msword'
		#text.add_header('Content-Disposition','attachment', filename='proc.doc')
		text["Content-Disposition"] = 'attachment; filename = "proc.doc" '
		
	with open(r'/Users/huangmingbin/Desktop/qrcode.png','rb') as bb:
		image = MIMEImage(bb.read())
		image.add_header('content-disposition','attachment', filename='test.png')

msg.attach(text)
	msg.attach(image)

server = smtplib.SMTP_SSL(smtp_server)
	server.connect(smtp_server,465) #连接smtp服务器
	server.login(from_addr, password) #登录
	server.set_debuglevel(1)
	server.sendmail(from_addr, to_addr, msg.as_string()) #发送
	server.quit() #退出
