使用python代码发送邮件

封装成类

from email import encoders
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart
from email.parser import BytesParser, Parser
import smtplib

class BsSmtplib:
    def __init__(self):
        self.email = '邮箱地址'
        self.pwd = '邮箱密码'
        self.host = "smtp.mxhichina.com"   #不同类型邮箱这里需要修改
        self.port = "465" #不同类型邮箱这里需要修改

    def send_text(self, subject, msg_text, to_recipients):
        if not isinstance(to_recipients, list):
            raise TypeError('to_recipients类型不正确，需要时list类型。')
        msg = MIMEText(msg_text)
        msg['Subject'] = subject
        msg['From'] = self.email
        msg['To'] = ', '.join(to_recipients)

        server = smtplib.SMTP_SSL(self.host, self.port)
        server.login(self.email, self.pwd)
        server.sendmail(self.email, to_recipients, msg.as_string())
        server.quit()

    def send_with_attachments(self, subject, msg_html, to_recipients, images=None, atts=None):
        if not isinstance(to_recipients, list):
            raise TypeError('to_recipients类型不正确，需要时list类型。')
        msg = MIMEMultipart()
        msg['Subject'] = subject
        msg['From'] = self.email
        msg['To'] = ','.join(to_recipients)
        html_body = MIMEText(msg_html, 'html')
        msg.attach(html_body)

        if images is not None:
            for f_name in images:
                with open(f_name, 'rb') as f:
                    img = MIMEImage(f.read())
                    img.add_header('Content-Disposition',
                                   'attachment',
                                   filename=os.path.basename(f_name))
                    msg.attach(img)

        if atts is not None:
            for att in atts:
                part = MIMEBase('application', "octet-stream")
                with open(att, 'rb') as f:
                    part.set_payload(f.read())
                    encoders.encode_base64(part)
                    part.add_header(
                        'Content-Disposition',
                        'attachment; filename="{}"'.format(os.path.basename(att))
                    )
                    msg.attach(part)
        print(to_recipients)
        server = smtplib.SMTP_SSL(self.host, self.port)
        server.login(self.email, self.pwd)
        server.sendmail(self.email, to_recipients, msg.as_string())
        server.quit()

用法

MailSend = BsSmtplib()
subject ="邮件标题"
content ="##########邮件内容##########"
to_recipients = ['收件箱地址1','收件箱地址2','收件箱地址3']
MailSend.send_with_attachments(subject,content,to_recipients)
