python发送文件夹内容到邮箱

发表评论

由于我经常需要备份文件夹下的内容到邮件里面，每个打开邮件，上传文件，发送，太过麻烦，其实每次发送的文件都是放在固定 置的，只是邮件标题不同而已，于是用 python 为自己写了个发送文件到邮箱的小工具，在任意目录下执行该脚本，并指定邮件标 ，就将指定文件夹下的文件发送到邮箱中备份起来 。

from smtplib import SMTP, quotedata, CRLF, SMTPDataError

from sys import stderr, stdout

class ExtendedSMTP(SMTP):
    def data(self, msg):
        self.putcmd("data")
        (code,repl)=self.getreply()
        if self.debuglevel > 0 : print >> stderr, "data:", (code, repl)
        if code != 354:
            raise SMTPDataError(code,repl)
        else:
            q = quotedata(msg)
            if q[-2:] != CRLF:
                q = q + CRLF
            q = q + "." + CRLF

            # begin modified send code
            chunk_size = 2048
            bytes_sent = 0

            while bytes_sent != len(q):
                chunk = q[bytes_sent:bytes_sent+chunk_size]
                self.send(chunk)
                bytes_sent += len(chunk)
                if hasattr(self, "callback"):
                    self.callback(bytes_sent, len(q))

            (code,msg)=self.getreply()
            if self.debuglevel >0 : print>>stderr, "data:", (code,msg)
            return (code,msg)

def callback(progress, total):
    percent = 100. * progress / total
    stdout.write('\r')
    stdout.write("%s bytes sent of %s [%2.0f%%]" % (progress, total, percent))
    stdout.flush()
    if percent >= 100: stdout.write('\n')

def sendmail(subject):
    MAIL_FROM = 'mymail@qq.com'
    MAIL_TO = ['mymail@qq.com']
    BAK_DIR = '/path/to/bak/folder'

    msg = MIMEMultipart()
    msg['From'] = MAIL_FROM
    msg['Subject'] = subject

    msg.attach( MIMEText('test send attachment') )
    for filename in os.listdir(BAK_DIR):
        part = MIMEBase('application', "octet-stream")
        part.set_payload(open(os.path.join(BAK_DIR, filename),"rb").read() )
        Encoders.encode_base64(part)
        part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(filename))
        msg.attach(part)

    try:
        smtp = ExtendedSMTP()
        smtp.callback = callback
        smtp.connect('smtp.qq.com', 25)
        smtp.login('mymail', 'mypwd')
        smtp.sendmail(MAIL_FROM, MAIL_TO, msg.as_string())
        smtp.close()
        os.system('rm -f %s/*' % BAK_DIR)
    except Exception, e:
        print e

if __name__ == '__main__':
    if len(sys.argv) == 1:
        print 'Please specific a subject'
        print 'Usage: send_files <MAIL_SUBJECT>'
    else:
        sendmail(sys.argv[1])

安装：

配置好收件人，发件人，smtp地址，用户名，密码及要发送文件所在的路径。

将文件保存为 send_files，保存到 /usr/bin 下面。

然后设置文件权限为可执行：

$ chmod +x send_files

用法：

$ send_files '邮件标题'

还带有进度条哦～～
