python SendMail 发送邮件

　　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：

　　

　　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）

　　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
