Python 发送邮件

1、案例一 (发送普通邮件)

import smtplib
from email.mime.text import MIMEText


# 发送普通邮件
# POP3 服务器地址：pop.qq.com
# SMTP 服务器地址：smtp.qq.com

class SendEmail:
    def __init__(self):
        # 发送邮件的用户
        self.send_user = '[email protected]'
        # SMTP 服务器地址：smtp.qq.com
        self.email_host = 'smtp.qq.com'
        # 服务器端口 465
        self.email_port = 465
        # 开启POP3/SMTP服务,在第三方客户端登录时，生成的授权码
        self.password = 'xxxxxxxxx'

    def send_email(self, title, data, user_list):
        try:
            message = MIMEText(data, _subtype='plain', _charset='utf-8')
            message['Subject'] = title
            message['From'] = self.send_user
            message['To'] = ";".join(user_list)
            server = smtplib.SMTP_SSL()
            server.connect(self.email_host, self.email_port)
            server.login(self.send_user, self.password)
            server.sendmail(self.send_user, user_list, message.as_string())
            server.close()
            print("发送邮件成功，请查收")
        except Exception as e:
            print("发送邮件失败，报错信息：", e)


if __name__ == '__main__':
    user_list = ["[email protected]"]
    title = "邮件标题"
    data = "邮件内容"
    send = SendEmail()
    send.send_email(title, data, user_list)

2、案例二 (发送带附件的邮件)

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart


# 发送带附件的邮件
# POP3 服务器地址：pop.qq.com
# SMTP 服务器地址：smtp.qq.com

class SendEmail:
    def __init__(self):
        # 发送邮件的用户
        self.send_user = '[email protected]'
        # SMTP 服务器地址：smtp.qq.com
        self.email_host = 'smtp.qq.com'
        # 服务器端口 465
        self.email_port = 465
        # 开启POP3/SMTP服务,在第三方客户端登录时，生成的授权码
        self.password = 'xxxxxxxxx'

    def send_email(self, title, data, file_path_list, user_list):
        try:
            # 创建一个带附件的实例
            message = MIMEMultipart()
            message.attach(MIMEText(data, 'plain', 'utf-8'))
            message['Subject'] = title
            message['From'] = self.send_user
            message['To'] = ";".join(user_list)
            for file_path in file_path_list:
                # 构造附件
                attrs = MIMEText(open(file_path, 'rb').read(), 'base64', 'utf-8')
                attrs["Content-Type"] = 'application/octet-stream'
                # 这里的filename可以任意写，写什么名字，邮件中显示什么名字
                attrs["Content-Disposition"] = 'attachment; filename={}'.format(str(file_path).split('/')[-1])
                message.attach(attrs)
            server = smtplib.SMTP_SSL()
            server.connect(self.email_host, self.email_port)
            server.login(self.send_user, self.password)
            server.sendmail(self.send_user, user_list, message.as_string())
            server.close()
            print("发送邮件成功，请查收")
        except Exception as e:
            print("发送邮件失败，报错信息：", e)


if __name__ == '__main__':
    user_list = ["[email protected]"]
    title = "邮件标题"
    data = "邮件内容"
    file_path_list = ['demo.jpg']
    send = SendEmail()
    send.send_email(title, data, file_path_list, user_list)

3、案例三 (发送一个HTML片段)

import smtplib
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart


# 发送一个HTML片段
# POP3 服务器地址：pop.qq.com
# SMTP 服务器地址：smtp.qq.com

class SendEmail:
    def __init__(self):
        # 发送邮件的用户
        self.send_user = '[email protected]'
        # SMTP 服务器地址：smtp.qq.com
        self.email_host = 'smtp.qq.com'
        # 服务器端口 465
        self.email_port = 465
        # 开启POP3/SMTP服务,在第三方客户端登录时，生成的授权码
        self.password = 'xxxxxxxxx'

    def send_email(self, title, data, user_list):
        try:
            message = MIMEMultipart('related')
            content = MIMEText(data, 'html', 'utf-8')
            message.attach(content)
            message['Subject'] = title
            message['From'] = self.send_user
            message['To'] = ";".join(user_list)
            file = open("demo.jpg", "rb")
            img_data = file.read()
            file.close()
            img = MIMEImage(img_data)
            img.add_header('Content-ID', 'image')
            message.attach(img)
            server = smtplib.SMTP_SSL()
            server.connect(self.email_host, self.email_port)
            server.login(self.send_user, self.password)
            server.sendmail(self.send_user, user_list, message.as_string())
            server.close()
            print("发送邮件成功，请查收")
        except Exception as e:
            print("发送邮件失败，报错信息：", e)


if __name__ == '__main__':
    user_list = ["[email protected]"]
    title = "邮件标题"
    data = """
        <p>全是BUG</p>
        <p><a href="https://www.cnblogs.com/xingxingnbsp/">菜鸟程序员博客</a></p>
        <p>图片演示：</p>
        <p><img src="cid:image"></p>
    """
    send = SendEmail()
    send.send_email(title, data, user_list)
