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 smtplibimport email.MIMEMultipartimport email.MIMETextimport email.MIMEBaseimport 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'] = Frommain_msg['To'] = Tomain_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()
