## 准备
1. 注册163邮箱
2. 开启smtp服务,获得授权码
3. 查阅163邮箱提供的smtp服务器地址和端口号`smtp.163.com,994`
4. 导入python自带的包
```python
import os
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email.mime.application import MIMEApplication
```
## 发送文本
以下为自己发送给自己纯文本邮件的demo:
``` python
def send_txt_email(a1,receiver="asciiart@163.com"):
subject = "滴滴答答"#邮件标题
sender = "asciiart@163.com"#发送方
content = "hello world {}！".format(a1)
recver = receiver#接收方
password = "****************"#授权码
message = MIMEText(content,"plain","utf-8")
#content 发送内容 "plain"文本格式 utf-8 编码格式
message['Subject'] = subject #邮件标题
message['To'] = recver #收件人
message['From'] = sender #发件人
smtp = smtplib.SMTP_SSL("smtp.163.com",994) #实例化smtp服务器
smtp.login(sender,password)#发件人登录
smtp.sendmail(sender,[recver],message.as_string()) #as_string 对 message 的消息进行了封装
smtp.close()
send_txt_email("李辰旭")
```
## 发送图片
可以以html格式来发送文本,附加图片
```python
def send_img_email(a1,a2,img_path='D:\\justplay\\asciiweb\\www\\tmp\\88.jpg',receiver="asciiart@163.com"):
TextContent = '''
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<h1>来自ascii-art的日志信息</h1>
<p>{}</p>
<p>{}</p>
<img src="cid:dns_config" alt="some_text">
</body>
</html>
'''.format(a1,a2)
sender = 'asciiart@163.com'
receiver = 'asciiart@163.com'
subject = 'ascii-art web log'
smtpserver = 'smtp.163.com'
password = '****************'
msgRoot = MIMEMultipart('related')
msgRoot['Subject'] = subject
msgText = MIMEText(
TextContent, 'html', 'utf-8')
msgRoot.attach(msgText)
fp = open(img_path, 'rb')
msgImage = MIMEImage(fp.read())
fp.close()
msgImage.add_header('Content-ID', 'dns_config')
msgRoot.attach(msgImage)
smtp = smtplib.SMTP()
smtp.connect(smtpserver)
smtp.login(sender, password)
smtp.sendmail(sender, receiver, msgRoot.as_string())
smtp.quit()
send_img_email('lcx','nb',"C:\\Users\\31646\\Pictures\\Saved Pictures\\lena.jpg")
```
## 发送附件
```python
def send_appendix_email(a1,a2,file_path='D:\\justplay\\asciiweb\\www\\tmp\\88.jpg',receiver="asciiart@163.com"):
TextContent = '''
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<h1>来自ascii-art的日志信息</h1>
<p>{}</p>
<p>{}</p>
</body>
</html>
'''.format(a1,a2)
sender = 'asciiart@163.com'
receiver = 'asciiart@163.com'
subject = 'ascii-art web log'
smtpserver = 'smtp.163.com'
#username = '***'
password = '****************'
msgRoot = MIMEMultipart('related')
msgRoot['Subject'] = subject
msgText = MIMEText(
TextContent, 'html', 'utf-8')
msgRoot.attach(msgText)
#构造附件txt附件1
fp = open(file_path, 'rb')
msgFile = MIMEApplication(fp.read())
fp.close()
_,filename = os.path.split(file_path)
#msgFile["content_Type"]='application/octet-stream'
msgFile["Content-Disposition"] = 'attachment; filename="{}"' .format(filename)
msgRoot.attach(msgFile)
smtp = smtplib.SMTP()
smtp.connect(smtpserver)
smtp.login(sender, password)
smtp.sendmail(sender, receiver, msgRoot.as_string())
smtp.quit()
send_appendix_email('lcx','nb',"C:\\Users\\31646\\Pictures\\Saved Pictures\\cat.ico")
```
## 部署在云服务器上
会出现超时的错误，这是因为25端口被ban了https://blog.csdn.net/codeHaoHao/article/details/82940865
只好用SSL协议发送邮件，服务器会使用465端口来发送。
改为如下格式https://blog.csdn.net/weixin_30687811/article/details/95815435
