python 发送邮件及附件

用授权码登录发送邮件及附件

需要对邮件进行POP3/SMTP服务设置，例如qq邮箱：

特别提示- --->    千万不要泄漏自己的授权码 

这里的邮箱的域名与端口根据自己的实际邮箱去填写（这是qq邮箱）

    send_email('smtp.qq.com', 465, '发送邮箱', '邮箱授权码', '接收邮箱', subject, content)
except Exception as err:
    print(err)

如果不需要附件可以把以下代码注释掉即可

part = MIMEApplication(open(r'C:\Users\zsjw_pachong01\Desktop\线上抓取指标统计表(1).xlsx', 'rb').read())
part.add_header('Content-Disposition', 'attachment', filename="线上抓取指标统计表(1).xlsx")  # 发送文件名称
msg.attach(part)

或者参考这段优化的代码

# 添加文件 emailSender.py
import smtplib
import datetime
from email.mime.text import MIMEText


class EmailSender(object):
    def __init__(self):
        self.smtp_host = "smtp.qq.com"  # 发送邮件的smtp服务器（从QQ邮箱中取得）
        self.smtp_user = "[email protected]"  # 用于登录smtp服务器的用户名，也就是发送者的邮箱
        self.smtp_pwd = "xxxxxxxxxxx"  # 授权码，和用户名user一起，用于登录smtp， 非邮箱密码
        self.smtp_port = 465  # smtp服务器SSL端口号，默认是465
        self.sender = [email protected]  # 发送方的邮箱

    def send_email(self, toLst, subject, body):
        '''
        发送邮件
        :param toLst: 收件人的邮箱列表["[email protected]", "[email protected]"]
        :param subject: 邮件标题
        :param body: 邮件内容
        :return:
        '''
        message = MIMEText(body, 'plain', 'utf-8')  # 邮件内容，格式，编码
        message['From'] = self.sender               # 发件人
        message['To'] = ",".join(toLst)             # 收件人列表
        message['Subject'] = subject                # 邮件标题
        try:
            smtpSSLClient = smtplib.SMTP_SSL(self.smtp_host, self.smtp_port)   # 实例化一个SMTP_SSL对象
            loginRes = smtpSSLClient.login(self.smtp_user, self.smtp_pwd)      # 登录smtp服务器
            print(f"登录结果：loginRes = {loginRes}")    # loginRes = (235, b'Authentication successful')
            if loginRes and loginRes[0] == 235:
                print(f"登录成功，code = {loginRes[0]}")
                smtpSSLClient.sendmail(self.sender, toLst, message.as_string())
                print(f"mail has been send successfully. message:{message.as_string()}")
                smtpSSLClient.quit()
            else:
                print(f"登陆失败，code = {loginRes[0]}")
        except Exception as e:
            print(f"发送失败，Exception: e={e}")

调用如下：

email = EmailSender()
toSendEmailLst = ['[email protected]']
finishTime = datetime.now()
subject = f"我是标题, finishedTime = {finishTime}"
body = "我是内容。。。"
email.send_email(toSendEmailLst, subject, body)

用户名，密码登录发送邮件和附件

如果只发文本内容，不需要发附件把以下注释掉即可

part = MIMEApplication(open(r'C:\Users\zsjw_pachong01\Desktop\线上抓取指标统计表(1).xlsx', 'rb').read())
part.add_header('Content-Disposition', 'attachment', filename="线上抓取指标统计表(1).xlsx")  # 发送文件名称
msg.attach(part)
