python 发送邮件的四种方法汇总

这里针对smtplib做了一系列封装，可以完成以下四种场景：

以上四种场景，已经做好了二次封装，经测试OK，使用时直接传入对应参数即可，直接上代码

import smtplibfrom email.mime.text import MIMETextfrom email.mime.image import MIMEImagefrom email.mime.application import MIMEApplicationfrom email.mime.multipart import MIMEMultipartclass SendEMail(object): '''封装发送邮件类''' def __init__(self, host, port, msg_from, pwd): self.msg_from = msg_from self.password = pwd # 邮箱服务器地址和端口 self.smtp_s = smtplib.SMTP_SSL(host=host, port=port) # 发送方邮箱账号和授权码 self.smtp_s.login(user=msg_from, password=pwd) def send_text(self, to_user, content, subject, content_type=’plain’): ''' 发送文本邮件 :param to_user: 对方邮箱 :param content: 邮件正文 :param subject: 邮件主题 :param content_type: 内容格式：’plain’ or ’html’ :return: ''' msg = MIMEText(content, _subtype=content_type, _charset='utf8') msg['From'] = self.msg_from msg['To'] = to_user msg['subject'] = subject self.smtp_s.send_message(msg, from_addr=self.msg_from, to_addrs=to_user) def send_file(self, to_user, content, subject, reports_path, filename, content_type=’plain’): ''' 发送带文件的邮件 :param to_user: 对方邮箱 :param content: 邮件正文 :param subject: 邮件主题 :param reports_path: 文件路径 :param filename: 邮件中显示的文件名称 :param content_type: 内容格式 ''' file_content = open(reports_path, 'rb').read() msg = MIMEMultipart() text_msg = MIMEText(content, _subtype=content_type, _charset='utf8') msg.attach(text_msg) file_msg = MIMEApplication(file_content) file_msg.add_header(’content-disposition’, ’attachment’, filename=filename) msg.attach(file_msg) msg['From'] = self.msg_from msg['To'] = to_user msg['subject'] = subject self.smtp_s.send_message(msg, from_addr=self.msg_from, to_addrs=to_user) def send_img(self, to_user, subject, content, filename, content_type=’html’): ’’’ 发送带图片的邮件 :param to_user: 对方邮箱 :param subject: 邮件主题 :param content: 邮件正文 :param filename: 图片路径 :param content_type: 内容格式 ’’’ subject = subject msg = MIMEMultipart(’related’) # Html正文必须包含<img src='cid:imageid' alt='imageid' height='100%> content = MIMEText(content, _subtype=content_type, _charset='utf8') msg.attach(content) msg[’Subject’] = subject msg[’From’] = self.msg_from msg[’To’] = to_user with open(filename, 'rb') as file: img_data = file.read() img = MIMEImage(img_data) img.add_header(’Content-ID’, ’imageid’) msg.attach(img) self.smtp_s.sendmail(self.msg_from, to_user, msg.as_string())
