Python发邮件详解

一、利用163的smtp发送邮件

import smtplibfrom email.mime.text import MIMETextfrom email.header import Header# 第三方SMTP服务mail_server = ''mail_port = 587mail_user = 'daw***an@'mail_pass = '*********' # 这里要使用授权码,而不是邮箱密码sender = 'daw***an@'receivers = ['daw***an@','dav***an@','dav***an@']# 需要定义三个参数# 第一个参数为文本内容# 第二个参数plain设置文本格式# 第三个参数utf-8设置编码格式message = MIMEText("Python发送邮件", "plain", "utf-8")message['From'] = sender # 由于邮箱安全认证，需要把发件人放到message['From'], 否由会”出现554 SPM错误“message['To'] = sender # 由于邮箱安全认证，需要把发件人放到message['To'], 否由会”出现554 SPM错误“subject = 'Python SMTP发送邮件测试'message['Subject'] = Header(subject, 'utf-8')try: mailserver = smtplib.SMTP_SSL(mail_host, 587)mailserver.login(mail_user, mail_pass) mailserver.sendmail(sender, receivers, message.as_string()) mailserver.quit() print('邮件发送成功')except smtplib.SMTPException: print("发送邮件失败！")

二、封装通用发邮件工具类

import osimport randomimport smtplibimport timefrom email.header import Headerfrom email.mime.text import MIMETextfrom email.mime.multipart import MIMEMultipartclass EmailUtils(object): def __init__(self, sender, receivers, username, password, smtp_server='', smtp_port=465): self.sender = sender self.receivers = receivers self.username = username self.password = password self.smtp_server=smtp_server self.smtp_port = smtp_port # 连接服务器 self.connect_server() def create_email(self, title): # 创建一个带附件的实例 message = MIMEMultipart() message['From'] = self.sender message['To'] = self.receivers message['Subject'] = Header(title, 'utf-8') self.message = message # 附件内容，如文本文件，图片文件等 def email_appendix(self, file_path): att1 = MIMEText(open(file_path, 'rb').read(), 'base64', 'utf-8') # 指定头部信息 att1['Content-Type'] = 'application/octet-stream' #内容为二进制流 att1['Content-Disposition'] = 'attachment; filename="%s"'%(os.path.basename(file_path)) self.message.attach(att1) def email_content(self, content, content_type='plain'): # 邮件正文内容 # plain正常文本内容，html可以发送html格式内容 self.message.attach(MIMEText(content, content_type, 'utf-8')) def connect_server(self): # 连接邮件的服务器 mailserver = smtplib.SMTP_SSL(self.smtp_server, self.smtp_port) try: # 连接qq的smtp服务器 mailserver.login(self.username, self.password) except smtplib.SMTPAuthenticationError: print('请检查用户名和授权码是否正确') return else: self.mailserver = mailserver def send_email(self): # 发送一封邮件 self.mailserver.sendmail(self.sender, self.receivers, self.message.as_string()) print('发送邮件成功！') def __del__(self): self.mailserver.close()if __name__ == "__main__":# 此处的密码为授权码 mail = EmailUtils(sender='dav***an@', receivers='dav***an@', username='dav***an@', password='**********') mail.create_email('创建一封测试邮件') # 添加邮件内容 mail.email_content('您好！欢迎阅读我的内容') # 添加附件mail.email_appendix('background.jpg') # 发送邮件 mail.send_email()
