python使用smtplib发邮件（带附件）代码，pythonsmtplib,简单实例源码：#codi

简单实例源码：

#coding=utf-8import smtplibfrom email.mime.text import MIMETextsender = 'your@email'mailto = 'target@email'#邮件信息msg =MIMEText("It's a text email!")msg['Subject'] = 'Hello world'msg['to'] = mailtomsg['From'] = sender#连接发送服务器smtp = smtplib.SMTP('smtp.xxx.xxx')smtp.login(username,password)#发送smtp.sendmail(sender,mailto,msg.as_string())smtp.quit()

类MIMEText()：用来生成text/* 类型的MIME邮件主体对象，完整参数格式是：MIMEText(_text, _subtype=’plain’, _charset=’us-ascii’)

_text：字符型的邮件内容对象；_subtype：MIME内容类型，默认为“普通”，如：MIMEText（text,’html’）指html格式的邮件内容；_charset：指定的字符集，如utf-8

发送带附件的邮件实例：

#coding=utf-8import smtplibfrom email.mime.multipart import MIMEMultipartfrom email.mime.text import MIMETextfrom email.mime.image import MIMEImagesender = 'your@email'mailto = 'target@email'imgfiles = 'text_1.png'msg = MIMEMultipart()msg['Subject'] = 'Test send image!'msg['To'] = mailtomsg['From'] = sender# 邮件内容Contents = MIMEText('<b>This is a img!</b>','html')msg.attach(Contents)# 带上二进制附件  att = MIMEImage(file(imgfiles, 'rb').read())  att["Content-Type"] = 'application/octet-stream'  att.add_header('content-disposition','attachment',filename=imgfiles)msg.attach(att)# 登录邮件发送服务器smtp = smtplib.SMTP('smtp.xxx.xxx')smtp.login(username,password)# 发送邮件smtp.sendmail(sender, mailto, msg.as_string())smtp.quit()

类MIMEMultipart()：用来生成包含多个部分的邮件体的MIME对象；类MIMEImage()：如MIMEText()，用来生成image/* 类型的MIME的邮件主体对象；

在邮件内容中插入图片：

imgData = MIMEImage(file(imgfiles, 'rb').read())imgData.add_header('Content-ID', '<%s>'% imgfiles)msg.attach(imgData )contents = MIMEText('<img src="cid:%s">'% imgfiles,'html')msg.attach(contents)
