SMTPServerDisconnected:请先执行connect()

Question

我正在探索flask，并试图设置一个简单的web应用程序与安全注册和登录。我用的是烧瓶安全软件。不幸的是，当我导航到发送确认页面时，我得到了错误:"smtpserverdisconnected: please run connect() first"。

以下是我写的相关文件。run.py驱动整个应用程序

run.py(在app文件夹旁边)

#!venv/bin/python
from app import app
app.run(debug = True)

下面的内容都在app文件夹

__init__ . py

from flask import Flask
from flask.ext.mail import Mail
from flask.ext.sqlalchemy import SQLAlchemy
app = Flask(__name__)
app.config.from_object('config')
db = SQLAlchemy(app)
mail = Mail(app)
import models
import views
@app.before_first_request
def create_user():
    db.create_all()
    models.user_datastore.create_user(email = '[e-mail]',
            password = 'password')
    db.session.commit()
if __name__ == '__main__':
    app.run()

models.py

from app import db, app
from flask.ext.sqlalchemy import SQLAlchemy
from flask.ext.security import SQLAlchemyUserDatastore,
        UserMixin, RoleMixin, Security
roles_users = db.Table('roles_users',
        db.Column('user_id', db.Integer(), db.ForeignKey('user.id')),
        db.Column('role_id', db.Integer(), db.ForeignKey('role.id')))
class Role(db.Model, RoleMixin):
    id = db.Column(db.Integer(), primary_key = True)
    name = db.Column(db.String(80), unique = True)
    description = db.Column(db.String(255))
class User(db.Model, UserMixin):
    id = db.Column(db.Integer, primary_key = True)
    email = db.Column(db.String(255), unique = True)
    password = db.Column(db.String(255))
    active = db.Column(db.Boolean())
    confirmed_at = db.Column(db.DateTime())
    roles = db.relationship('Role', secondary = roles_users,
            backref = db.backref('users', lazy = 'dynamic'))
user_datastore = SQLAlchemyUserDatastore(db, User, Role)
security = Security(app, user_datastore)

views.py

from app import app
from flask import render_template
from flask.ext.security import login_required
@app.route('/')
@login_required
def index():
    return render_template('index.html')

编辑:另外，这是我使用的配置文件

DEBUG      = True
SECRET_KEY = 'secret'
SQLALCHEMY_DATABASE_URI = 'sqlite://'
SECURITY_PASSWORD_HASH = 'sha512_crypt'
SECURITY_PASSWORD_SALT = 'salt'
SECURITY_CONFIRMABLE = True
SECURITY_REGISTERABLE = True
SECURITY_RECOVERABLE = True
SECURITY_TRACKABLE = True
SECURITY_CHANGEABLE = True
MAIL_SERVER = 'smtp.zoho.com'
MAIL_PORT = 465
MAIL_USE_TLS = False
MAIL_USE_SSL = True
MAIL_DEBUG = True
MAIL_USERNAME = 'myaddress@mydomain'
MAIL_PASSWORD = 'password'

Answer 1

好了，我知道问题是什么了。默认情况下，flask-security设置为以"localhost"发送邮件。我的邮件提供商是Zoho，但我只是将它们用作我运行的一个域的邮件服务器。我的邮件设置是这样的，我只能从某些地址发送邮件。因为'localhost'不是其中之一，所以flask-security无法连接到Zoho的服务器。

因此，解决方案是在我的配置文件中添加 行

SECURITY_EMAIL_SENDER = 'valid_email@my_domain.com'

希望这将节省其他人试图找出为什么flask-security的电子邮件不工作的一些时间。
