运用Python3发送邮件
方法一 使用自己的smtp服务器
如果想用自己的服务器作为smtp服务器，首先要执行下面的命令：
python3 -m smtpd -n -c DebuggingServer localhost:1025 &
发送邮件的代码也要做出修改
server = smtplib.SMTP(host='smtp.gmail.com', port=1025)发送邮件的代码如下：
#!/usr/bin/python3
import smtplib
from email.mime.text import MIMEText
from email.header import Header
sender = '[email protected]'
receivers = ['[email protected]'] # 接收邮件，可设置为你的QQ邮箱或者其他邮箱
# 三个参数：第一个为文本内容，第二个 plain 设置文本格式，第三个 utf-8 设置编码
message = MIMEText('Python 邮件发送测试...', 'plain', 'utf-8')
message['From'] = Header("chen", 'utf-8') # 发送者
message['To'] = Header("测试", 'utf-8') # 接收者
subject = 'Python SMTP 邮件测试'
message['Subject'] = Header(subject, 'utf-8')
try:
smtpObj = smtplib.SMTP('localhost')
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")
方法二：使用第三方smtp服务器
import smtplib
from email.header import Header
from email.mime.text import MIMEText
# 第三方 SMTP 服务
mail_host = "smtp.163.com" # SMTP服务器
mail_user = "[email protected]" # 用户名
mail_pass = "xxxxx" # 授权密码，非登录密码
sender = '[email protected]' # 发件人邮箱(最好写全, 不然会失败)
receivers = ['[email protected]'] # 接收邮件，可设置为你的QQ邮箱或者其他邮箱
content = '你好，有你的邮件'
title = 'Python邮件' # 邮件主题
def sendEmail():
message = MIMEText(content, 'plain', 'utf-8') # 内容, 格式, 编码
message['From'] = "{}".format(sender)
message['To'] = ",".join(receivers)
message['Subject'] = title
try:
smtpObj = smtplib.SMTP_SSL(mail_host, 465) # 启用SSL发信, 端口一般是465
smtpObj.login(mail_user, mail_pass) # 登录验证
smtpObj.sendmail(sender, receivers, message.as_string()) # 发送
print("mail has been send successfully.")
except smtplib.SMTPException as e:
print(e)
def send_email2(SMTP_host, from_account, from_passwd, to_account, subject, content):
email_client = smtplib.SMTP(SMTP_host)
email_client.login(from_account, from_passwd)
# create msg
msg = MIMEText(content, 'plain', 'utf-8')
msg['Subject'] = Header(subject, 'utf-8') # subject
msg['From'] = from_account
msg['To'] = to_account
email_client.sendmail(from_account, to_account, msg.as_string())
email_client.quit()
if __name__ == '__main__':
sendEmail()
# receiver = '***'
# send_email2(mail_host, mail_user, mail_pass, receiver, title, content)
