使用Python如何实现发送邮件和发送带附件的邮件

import smtplib
# 发送字符串的邮件
from email.mime.text import MIMEText

# 设置服务器所需信息
fromEmailAddr = '发件人邮箱地址' # 邮件发送方邮箱地址
password = 'email password' # 密码(部分邮箱为授权码)
toEmailAddrs = ['接收方地址'] # 邮件接受方邮箱地址，注意需要[]包裹，这意味着你可以写多个邮件地址群发

# 设置email信息
# ---------------------------发送字符串的邮件-----------------------------
# 邮件内容设置
message = MIMEText('hello,test Python send Email.', 'plain', 'utf-8')
# 邮件主题
message['Subject'] = 'python test email'
# 发送方信息
message['From'] = fromEmailAddr
# 接受方信息
message['To'] = toEmailAddrs[0]
# ---------------------------------------------------------------------


# 登录并发送邮件
try:
 server = smtplib.SMTP('smtp.163.com') # 163邮箱服务器地址，端口默认为25
 server.login(fromEmailAddr, password)
 server.sendmail(fromEmailAddr, toEmailAddrs, message.as_string())
 print('success')
 server.quit()
except smtplib.SMTPException as e:
 print("error:", e)

import smtplib
# 发送字符串的邮件
from email.mime.text import MIMEText
# 需要 MIMEMultipart 类
from email.mime.multipart import MIMEMultipart

# 设置服务器所需信息
fromEmailAddr = '发件人邮箱地址' # 邮件发送方邮箱地址
password = 'email password' # 密码(部分邮箱为授权码)
toEmailAddrs = ['收件人地址'] # 邮件接受方邮箱地址，注意需要[]包裹，这意味着你可以写多个邮件地址群发

# 设置email信息
# ---------------------------发送带附件邮件-----------------------------
# 邮件内容设置
message = MIMEMultipart()
# 邮件主题
message['Subject'] = 'python test email'
# 发送方信息
message['From'] = fromEmailAddr
# 接受方信息
message['To'] = toEmailAddrs[0]
# 邮件正文内容
message.attach(MIMEText('hello,test Python send Email', 'plain', 'utf-8'))

# 构造附件
att1 = MIMEText(open('text.txt', 'rb').read(), 'base64', 'utf-8')
att1['Content-type'] = 'application/octet-stream'
att1['Content-Disposition'] = 'attachment; filename="test.zip"'
message.attach(att1)
# ---------------------------------------------------------------------

# 登录并发送邮件
try:
 server = smtplib.SMTP('smtp.163.com') # 163邮箱服务器地址，端口默认为25
 server.login(fromEmailAddr, password)
 server.sendmail(fromEmailAddr, toEmailAddrs, message.as_string())
 print('success')
 server.quit()
except smtplib.SMTPException as e:
 print("error:", e)
