python SendMail 发送邮件

时间:2023-12-21 11:14:20

  最近在学习python 时,用到了发送邮件的操作,通过整理总结如下:

  

     一、相关模块介绍

  发送邮件主要用到了smtplib和email两个模块,这里首先就两个模块进行一下简单的介绍:
      smtplib模块

   smtplib.SMTP([host[, port[, local_hostname[, timeout]]]])

     SMTP类构造函数,表示与SMTP服务器之间的连接,通过这个连接可以向smtp服务器发送指令,执行相关操作(如:登陆、发送邮件)。所有参数都是可选的。

   host:smtp服务器主机名

  port:smtp服务的端口,默认是25;如果在创建SMTP对象的时候提供了这两个参数,在初始化的时候会自动调用connect方法去连接服务器。

     smtplib模块还提供了SMTP_SSL类和LMTP类,对它们的操作与SMTP基本一致。

   smtplib.SMTP提供的方法:

   SMTP.set_debuglevel(level):设置是否为调试模式。默认为False,即非调试模式,表示不输出任何调试信息。

   SMTP.connect([host[, port]]):连接到指定的smtp服务器。参数分别表示smpt主机和端口。注意: 也可以在host参数中指定端口号(如:smpt.yeah.net:25),这样就没必要给出port参数。

  SMTP.docmd(cmd[, argstring]):向smtp服务器发送指令。可选参数argstring表示指令的参数。

  SMTP.helo([hostname]) :使用"helo"指令向服务器确认身份。相当于告诉smtp服务器“我是谁”。

  SMTP.has_extn(name):判断指定名称在服务器邮件列表中是否存在。出于安全考虑,smtp服务器往往屏蔽了该指令。

  SMTP.verify(address) :判断指定邮件地址是否在服务器中存在。出于安全考虑,smtp服务器往往屏蔽了该指令。

   SMTP.login(user, password) :登陆到smtp服务器。现在几乎所有的smtp服务器,都必须在验证用户信息合法之后才允许发送邮件。

  SMTP.sendmail(from_addr, to_addrs, msg[, mail_options, rcpt_options]) :发送邮件。这里要注意一下第三个参数,msg是字符串,表示邮件。我们知道邮件一般由标题,发信人,收件人,邮件内容,

   附件等构成,发送邮件的时候,要注意msg的格式。这个格式就是smtp协议中定义的格式。

  SMTP.quit() :断开与smtp服务器的连接,相当于发送"quit"指令。(很多程序中都用到了smtp.close(),具体与quit的区别google了一下,也没找到答案。)

  email模块

  emial模块用来处理邮件消息,包括MIME和其他基于RFC 2822 的消息文档。使用这些模块来定义邮件的内容,是非常简单的。其包括的类有(更加详细的介绍可见:http://docs.python.org/library/email.mime.html):

   class email.mime.base.MIMEBase(_maintype, _subtype, **_params):这是MIME的一个基类。一般不需要在使用时创建实例。其中_maintype是内容类型,如text或者image。

   _subtype是内容的minor type 类型,如plain或者gif。 **_params是一个字典,直接传递给Message.add_header()。

  class email.mime.multipart.MIMEMultipart([_subtype[, boundary[, _subparts[, _params]]]]:MIMEBase的一个子类,多个MIME对象的集合,_subtype默认值为mixed。boundary是MIMEMultipart的边界,默认边界是可数的。

  class email.mime.application.MIMEApplication(_data[, _subtype[, _encoder[, **_params]]]):MIMEMultipart的一个子类。

   class email.mime.audio. MIMEAudio(_audiodata[, _subtype[, _encoder[, **_params]]]): MIME音频对象

  class email.mime.image.MIMEImage(_imagedata[, _subtype[, _encoder[, **_params]]]):MIME二进制文件对象。

  二、普通文本邮件

  普通文本邮件发送的实现,关键是要将MIMEText中_subtype设置为plain,首先导入smtplib和mimetext,创建smtplib.smtp实例,connect邮件smtp服务器,login后发送,具体代码如下:(python2.7下实现)

具体代码如下:

  python SendMail 发送邮件



  二、html邮件的发送

与text邮件不同之处就是将将MIMEText中_subtype设置为html。具体代码如下:(python2.7下实现)

  python SendMail 发送邮件

  三、发送带附件的邮件

发送带附件的邮件,首先要创建MIMEMultipart()实例,然后构造附件,如果有多个附件,可依次构造,最后利用smtplib.smtp发送。

  

    def SendMailAttach(self, mail_tolist, mail_subject, mail_body, fileList, mail_cclist):
'''
发送带附件的邮件
:param mail_tolist: 接收者邮件列表,如:['xiaoli@sina.com','xiaoMa@qq.com']
:param mail_subject: 邮件主题
:param mail_body: 邮件体主题内容
:param fileList: 附件列表,就文件名列表(包含路径)
:param mail_cclist: 抄送邮件列表,如:['xiaoli@sina.com','xiaoMa@qq.com'],默认不传
:param mail_bcclist: 密送邮件列表,如:['xiaoli@sina.com','xiaoMa@qq.com'],默认不传
:return:
'''
msg = MIMEMultipart()
message = MIMEText(mail_body, _subtype='plain', _charset='utf-8')
msg.attach(message) # 构造附件
for f in fileList:
if os.path.isfile(f):
att = MIMEText(open(f, 'rb').read(), 'base64', 'utf-8')
att["Content-Type"] = 'application/octet-stream'
att["Content-Disposition"] = 'attachment;filename=' + os.path.basename(f)
msg.attach(att) msg['Subject'] = mail_subject
msg['From'] = self.mail_sender
msg['To'] = ",".join(mail_tolist)
if len(mail_cclist) > 0:
msg['Cc'] = ",".join(mail_cclist)
mail_tolist.extend(mail_cclist)
# if len(mail_bcclist) > 0:
# msg['Bcc'] = ",".join(mail_bcclist)
# mail_tolist.extend(mail_bcclist) message = ''
try:
server = smtplib.SMTP()
server.connect(self.mail_host)
server.login(self.mail_user, self.mail_pass)
server.sendmail(self.mail_sender, mail_tolist, msg.as_string())
server.close()
result = '邮件发送成功' except smtplib.SMTPException as e:
# print "Error: 无法发送邮件", e
message = 'Error: 无法发送邮件:'
return message
