flask_mail发送邮件(使用SMTP协议)

本文介绍使用flask_mail发送邮件

0.获取邮箱的授权码(这里以163邮箱为例)

登录邮箱点击设置中的POP3/SMTP/IMAP获取授权码

• 这里授权码只展示一次，记得记下来

1.安装flask_mail

pip install flask_mail

2.导包

from flask import Flask,render_template,request
from flask_mail import Mail,Message
from flask_wtf import FlaskForm
from wtforms.validators import DataRequired
from wtforms import SubmitField,StringField,PasswordField

3.配置 config

app = Flask(__name__)

app.config["SECRET_KEY"] = "12345678"
#如果是qq邮箱这里应该为"smtp.qq.com"
app.config['MAIL_SERVER'] = "smtp.163.com"
#如果使用ssl则端口号应为465
app.config['MAIL_PORT'] = 465
app.config['MAIL_USE_SSL'] = True
#发送人的邮箱
app.config['MAIL_USERNAME'] = "[e-mail]"
# 这里的密码是之前获取的邮箱授权码
app.config['MAIL_PASSWORD'] = "TOWXXXXXXXMYQF"
# 显示发送人的名字
app.config['MAIL_DEFAULT_SENDER'] = '[e-mail]'

4.实例化Mail

mail = Mail(app)

5.定义邮件发送函数，recipient为收件人的邮箱，例如：[e-mail]

def send_email(recipient):
	#recipients参数可以指定多个收件人
    message = Message(subject='Overleaf 密码设置',recipients=[recipient])
    #如果发送文本，可在上面一行中添加：body='文本内容'
    #这里可以发送一个html页面
    message.html = render_template('content.html')
    mail.send(message)	#发送邮件

6.定义表单类

class SignUpForm(FlaskForm):
    email = StringField(validators=[DataRequired()],render_kw={'class':"form-control"})
    password = PasswordField(validators=[DataRequired()],render_kw={"class":"form-control"})
    submit = SubmitField("Sign up",render_kw={"class":"btn-primary btn"})

6.定义视图函数

这里从前端表单获取邮箱地址

@app.route('/',methods=['POST','GET'])
def sign_up():
    sp_form = SignUpForm()
    if sp_form.validate_on_submit():
        recipient = request.form.get("email")
        try:
            send_email(recipient)
        except:
            return render_template('wrong.html')
        else:
            return render_template('success.html',address=recipient)
    return render_template('sign_up.html',form=sp_form)

if __name__ == '__main__':
    app.run()

当前端提交表单后，可向获取的email地址发送一个邮件，效果如下：
