Flask用户登陆系统（二）添加注册发送邮件的功能

之前的功能参考文章  https://blog.csdn.net/scwMason/article/details/86764431

#send_email.py
from email.mime.text import MIMEText
from email.header import Header
from email.mime.multipart import MIMEMultipart
from email import encoders
from email.utils import parseaddr,formataddr
import smtplib
from_addr="[email protected]"
password="scw3837319scw911"
smtplib_server='smtp.sina.com'
msg=MIMEMultipart()
msg['From']=Header(from_addr)
msg['Subject']=Header('Bear Home Regist Information')

将我们的注册视图函数更改为

def register():
    if current_user.is_authenticated:
        return redirect(url_for('index'))
    form=RegistrationForm()
    if form.validate_on_submit():
        user=User(nickname=form.nickname.data,email=form.email.data,password=form.password.data)
        content=MIMEText(
            "Your Bear Home username is %s,password is %s"%(form.nickname.data,form.password.data),
            'plain',
            'utf-8'
        )
        msg.attach(content)
        try:
            server=smtplib.SMTP()
            server.connect(smtplib_server,25)
            server.set_debuglevel(1)
            server.login(from_addr,password)
            server.sendmail(from_addr,form.email.data,msg.as_string())
            print("Successfully send")
        except smtlib.SMTPException as e:
            server.quit()
            print('发送失败')
            pass
        db.session.add(user)
        db.session.commit()
        flash('Congratulations, you are now a registered user!')
        return redirect(url_for('login'))
    return render_template('register.html',title="Register",form=form)
