flask发送电子邮件

1.单线程的发送

# encoding: utf-8
import sys
from flask import Flask, url_for
# Mail可以看作是邮件的客户端
# Message代表当前要发出的信息，主题/内容/接收人都封装在这里面
from flask_mail import Mail, Message

reload(sys)
sys.setdefaultencoding(\'utf-8\')
app = Flask(__name__)

# 配置邮件：服务器／端口／安全套接字层／邮箱名／授权码/默认的发送人
app.config[\'MAIL_SERVER\'] = "smtp.qq.com"
app.config[\'MAIL_PORT\'] = 465
app.config[\'MAIL_USE_SSL\'] = True
app.config[\'MAIL_USERNAME\'] = "123456@qq.com"
# 这里的密码是你在邮箱中的授权码
app.config[\'MAIL_PASSWORD\'] = "qyzlojxdaledcmhbjbb"
# 显示发送人的名字
app.config[\'MAIL_DEFAULT_SENDER\'] = \'123456<123456@qq.com>\'

mail = Mail(app)


@app.route(\'/\')
def index():
    return \'<a href="{}">发送邮件<a/>\'.format(url_for(\'send_mail\'))


@app.route(\'/send_mail\')
def send_mail():
    message = Message(\'我是邮件的主题\', [\'123456@163.com\'])
    # message.body = \'我是内容\'
    message.html = \'<h1>我也是内容<h1/>\'
    mail.send(message)
    return \'邮件发送中......\'


if __name__ == \'__main__\':
    app.run(debug=True)

2.多线程的发送

# encoding: utf-8
import sys
from flask import Flask, url_for
# Mail可以看作是邮件的客户端
# Message代表当前要发出的信息，主题/内容/接收人都封装在这里面
from flask_mail import Mail, Message
from threading import Thread

reload(sys)
sys.setdefaultencoding(\'utf-8\')
app = Flask(__name__)

# 配置邮件：服务器／端口／安全套接字层／邮箱名／授权码/默认的发送人
app.config[\'MAIL_SERVER\'] = "smtp.qq.com"
app.config[\'MAIL_PORT\'] = 465
app.config[\'MAIL_USE_SSL\'] = True
app.config[\'MAIL_USERNAME\'] = "123456@qq.com"
# 这里的密码是你在邮箱中的授权码
app.config[\'MAIL_PASSWORD\'] = "qyzlojxdaledcmhbjbb"
# 显示发送人的名字
app.config[\'MAIL_DEFAULT_SENDER\'] = \'123456<123456@qq.com>\'

mail = Mail(app)


def send_mail_thread(message):
    # 在新的线程中要，手动开启应用上下文，不然会报错
    # RuntimeError: Working outside of application context.
    with app.app_context():
        mail.send(message)


@app.route(\'/\')
def index():
    return \'<a href="{}">发送邮件<a/>\'.format(url_for(\'send_mail\'))


@app.route(\'/send_mail\')
def send_mail():
    message = Message(\'我是邮件的主题\', [\'123456@163.com\'])
    # message.body = \'我是内容\'
    message.html = \'<h1>我是内容<h1/>\'
    thread = Thread(target=send_mail_thread, args=(message,))
    thread.start()
    return \'邮件发送中......\'


if __name__ == \'__main__\':
    app.run(debug=True)
