使用smtp发送邮件

 

1、发送普通文字邮件

from email.mime.text import MIMEText
msg = MIMEText('hello, send by Python...', 'plain', 'utf-8')
# 输入Email地址和口令:
from_addr = 'xxxxx@163.com'
password = 'xxxxx' #邮箱开启smtp服务获取的授权码
# 输入收件人地址:
to_addr = 'xxxxxx@163.com'
# 输入SMTP服务器地址:
smtp_server = 'smtp.163.com'

import smtplib
server = smtplib.SMTP(smtp_server, 25) # SMTP协议默认端口是25
server.set_debuglevel(1)
server.login(from_addr, password)
server.sendmail(from_addr, [to_addr], msg.as_string())
server.quit()

2、发送带附件邮件

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

sender = 'xxxxxx@163.com'
password = 'xxxxxx'
receivers = ['xxxxxx@163.com']  # 接收邮件

# 创建一个带附件的实例
message = MIMEMultipart()
message['From'] = Header("测试啦啦啦", 'utf-8')
message['To'] = Header("测试", 'utf-8')
subject = 'Python SMTP 邮件测试'
message['Subject'] = Header(subject, 'utf-8')

# 邮件正文内容
message.attach(MIMEText('邮件发送测试……', 'plain', 'utf-8'))

# 构造附件1，传送当前目录下的 t1.py 文件
att1 = MIMEText(open('t1.py', 'rb').read(), 'base64', 'utf-8')
att1["Content-Type"] = 'application/octet-stream'
# 这里的filename可以任意写，写什么名字，邮件中显示什么名字
att1["Content-Disposition"] = 'attachment; filename="t1.py"'
message.attach(att1)

try:
    smtpObj = smtplib.SMTP('smtp.163.com')
    smtpObj.login(sender,password)  # 测试时需要登录
    smtpObj.sendmail(sender, receivers, message.as_string())
    print("邮件发送成功")

except smtplib.SMTPException:
    print("Error: 无法发送邮件")
