Python SMTP 发送带附件电子邮件

可采用email模块发送电子邮件附件。发送一个未知MIME类型的文件附件其基本思路如下：

1. 构造MIMEMultipart对象做为根容器
2. 构造MIMEText对象做为邮件显示内容并附加到根容器
3. 构造MIMEBase对象做为文件附件内容并附加到根容器
　　a. 读入文件内容并格式化
　　b. 设置附件头
4. 设置根容器属性
5. 得到格式化后的完整文本
6. 用smtp发送邮件

具体内容参见<programing python(3rd)> 14章第6节 “email: Parsing and Composing Mails”。发送一个未知MIME类型的文件附件实例代码如下：

import smtplib
import email.MIMEMultipart
import email.MIMEText
import email.MIMEBase
import os.path
 
From = "sender address"
To = "recipients"
file_name = "file name"
 
server = smtplib.SMTP("smtp server address")
server.login("username","password") #仅smtp服务器需要验证时
 
# 构造MIMEMultipart对象做为根容器
main_msg = email.MIMEMultipart.MIMEMultipart()
 
# 构造MIMEText对象做为邮件显示内容并附加到根容器
text_msg = email.MIMEText.MIMEText("this is a test text to text mime")
main_msg.attach(text_msg)
 
# 构造MIMEBase对象做为文件附件内容并附加到根容器
contype = 'application/octet-stream'
maintype, subtype = contype.split('/', 1)
 
## 读入文件内容并格式化
data = open(file_name, 'rb')
file_msg = email.MIMEBase.MIMEBase(maintype, subtype)
file_msg.set_payload(data.read( ))
data.close( )
email.Encoders.encode_base64(file_msg)
 
## 设置附件头
basename = os.path.basename(file_name)
file_msg.add_header('Content-Disposition',
 'attachment', filename = basename)
main_msg.attach(file_msg)
 
# 设置根容器属性
main_msg['From'] = From
main_msg['To'] = To
main_msg['Subject'] = "attach test "
main_msg['Date'] = email.Utils.formatdate( )
 
# 得到格式化后的完整文本
fullText = main_msg.as_string( )
 
# 用smtp发送邮件
try:
    server.sendmail(From, To, fullText)
finally:
    server.quit()
