在使用腾讯企业邮箱发送邮件时出现报错：AttributeError: ‘list‘ object has no attribute ‘encode‘
原因：收件人不能用列表存储数据，需要转为字符串，以逗号分割
解决方法：
将收件人列表转为字符串，以逗号分割
to_list = [‘a@xx.com‘, ‘b@xx.com‘] msg[‘to‘] = ‘,‘.join(to_list)
完整代码：
import smtplib from email.mime.text import MIMEText from email.header import Header name = ‘xx@xxx.cn‘ pwd = ‘xxx‘ to_list = [‘xx@xxx.cn‘] content = ‘<html><head><title>test</title></head><body>这是测试邮件内容</body></html>‘ msg = MIMEText(content, ‘html‘, ‘utf-8‘) msg[‘form‘] = Header(‘huyang‘, ‘utf-8‘) msg[‘to‘] = ‘,‘.join(to_list) # 重点是这个位置 msg[‘subject‘] = Header(‘测试邮件‘, ‘utf-8‘) #---发送 smtp = smtplib.SMTP_SSL(‘smtp.exmail.qq.com‘, 465) smtp.login(name, pwd) smtp.sendmail(name, to_list, msg.as_string()) print(‘发送成功!‘)
发送邮件时，报错：AttributeError: 'list' object has no attribute 'encode'
