python SMTP实现发送带附件电子邮件
本文实例为大家分享了python SMTP发送带附件电子邮件的具体代码,供大家参考,具体内容如下
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()
