使用MIMEText()模块在Python中编写带中文字符的邮件标题

在Python中发送具有中文字符的邮件标题的步骤如下：

1. 导入必要的模块：

import smtplib
from email.mime.text import MIMEText
from email.header import Header

2. 设置发件人、收件人和邮件主题：

sender = 'from@example.com'
receiver = 'to@example.com'
subject = '这是一个带有中文字符的邮件标题'

3. 创建邮件正文对象，并指定编码为utf-8：

message = MIMEText('邮件内容', 'plain', 'utf-8')

4. 设置邮件主题（标题）：

message['Subject'] = Header(subject, 'utf-8')

5. 设置发件人和收件人：

message['From'] = Header(sender, 'utf-8')
message['To'] = Header(receiver, 'utf-8')

6. 创建SMTP对象并登录到发件人的邮箱：

smtpObj = smtplib.SMTP('smtp.example.com', 25)
smtpObj.login('your-email@example.com', 'your-email-password')

7. 发送邮件：

smtpObj.sendmail(sender, receiver, message.as_string())

以下是一个完整的示例代码：

import smtplib
from email.mime.text import MIMEText
from email.header import Header

sender = 'from@example.com'
receiver = 'to@example.com'
subject = '这是一个带有中文字符的邮件标题'

message = MIMEText('邮件内容', 'plain', 'utf-8')
message['Subject'] = Header(subject, 'utf-8')
message['From'] = Header(sender, 'utf-8')
message['To'] = Header(receiver, 'utf-8')

smtpObj = smtplib.SMTP('smtp.example.com', 25)
smtpObj.login('your-email@example.com', 'your-email-password')
smtpObj.sendmail(sender, receiver, message.as_string())

print("邮件发送成功")

请注意替换示例代码中的发件人、收件人、SMTP服务器和相应的登录凭据。
