flask_mail邮箱认证仍遇到error535

Question

以下为代码

import os
from flask import Flask, render_template, session, redirect, url_for
from flask_script import Manager, Shell
from flask_bootstrap import Bootstrap
from flask_moment import Moment
from flask_wtf import FlaskForm
from wtforms import StringField, SubmitField

from flask_migrate import Migrate, MigrateCommand
from flask_mail import Mail, Message

basedir = os.path.abspath(os.path.dirname(__file__))

app = Flask(__name__)
app.config['SECRET_KEY'] = 'hard to guess string'
app.config['SQLALCHEMY_DATABASE_URI'] =\
    'sqlite:///' + os.path.join(basedir, 'data.sqlite')
app.config['SQLALCHEMY_COMMIT_ON_TEARDOWN'] = True
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
app.config['MAIL_SERVER'] = 'smtp.163.com'

manager = Manager(app)
bootstrap = Bootstrap(app)
moment = Moment(app)
db = SQLAlchemy(app)
migrate = Migrate(app, db)
mail = Mail(app)


class Role(db.Model):
    __tablename__ = 'roles'
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(64), unique=True)
    users = db.relationship('User', backref='role', lazy='dynamic')

    def __repr__(self):

    msg.body = render_template(template + '.txt', **kwargs)
    msg.html = render_template(template + '.html', **kwargs)
    mail.send(msg)


class NameForm(FlaskForm):
    name = StringField('What is your name?', validators=[Required()])
    submit = SubmitField('Submit')


def make_shell_context():
    return dict(app=app, db=db, User=User, Role=Role)
manager.add_command("shell", Shell(make_context=make_shell_context))
manager.add_command('db', MigrateCommand)


@app.errorhandler(404)
def page_not_found(e):
    return render_template('404.html'), 404


@app.errorhandler(500)

    return render_template('500.html'), 500


@app.route('/', methods=['GET', 'POST'])
def index():
    form = NameForm()
    if form.validate_on_submit():
        user = User.query.filter_by(username=form.name.data).first()
        if user is None:
            user = User(username=form.name.data)
            db.session.add(user)
            session['known'] = False
            if app.config['FLASKY_ADMIN']:
                send_email(app.config['FLASKY_ADMIN'], 'New User',
                           'mail/new_user', user=user)
        else:
            session['known'] = True
        session['name'] = form.name.data
        return redirect(url_for('index'))
    return render_template('index.html', form=form, name=session.get('name'),
                           known=session.get('known', False))


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

以下为命令行中输入的代码：

 (venv) D:\flasky>set MAIL_USERNAME='[e-mail]'

(venv) D:\flasky>set MAIL_PASSWORD='ucas0307'

(venv) D:\flasky>python hello.py shell

>>> from flask_mail import Message
>>> from hello import mail
>>> msg = Message('test subject', sender='[e-mail]',
... recipients=['[e-mail]'])
>>> msg.body = 'text body'
>>> msg.html = '<b>HTML</b> body'
>>> with app.app_context():
...     mail.send(msg)

其中MAIL_PASSWORD那是已开通pop3/stmp后的授权码，但这样仍遇到error535，问题如下：
Traceback (most recent call last):
File "", line 2, in
File "D:\flasky\venv\lib\site-packages\flask_mail.py", line 491, in send
with self.connect() as connection:
File "D:\flasky\venv\lib\site-packages\flask_mail.py", line 144, in enter
self.host = self.configure_host()
File "D:\flasky\venv\lib\site-packages\flask_mail.py", line 165, in configure_
host
host.login(self.mail.username, self.mail.password)
File "d:\python27\Lib\smtplib.py", line 622, in login
raise SMTPAuthenticationError(code, resp)
SMTPAuthenticationError: (535, 'Error: authentication failed')
请问问题出在哪里？

Answer 1

app.config['MAIL_PORT'] = 465
变成
app.config['MAIL_PORT'] = 994
下面这个连接是163的帮助
