烧瓶用户：使用烧瓶邮件发送确认邮件失败

Question

嗨，我正在使用 flask 用户来模拟使用确认邮件和登录进行注册，但是在注册阶段，当用户提交表单时，我收到错误消息，告诉我我没有初始化烧瓶邮件，而在我的代码中我得到了它的初始化所以我一直在寻找这个错误来自的潜在问题，但我并没有真正找到，所以如果有人可以帮助我修复它，我把来自错误的回溯放在下面

我也将初始化文件的代码放在下面初始化应用程序的位置

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
import os
from flask_user import SQLAlchemyAdapter, UserManager
db = SQLAlchemy()
from . models import User


def create_app():
    application = Flask(__name__)

    application.config['SECRET_KEY'] = os.urandom(24)
    application.config['CSRF_ENABLED'] = True
    application.config['DEBUG'] = True
    application.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///C:\\users\\hp\\travaux\\flask-projet\\flask_user_tuto\\mydb.db'
    application.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
    application.config['USER_ENABLE_EMAIL'] = True
    application.config['MAIL_USERNAME'] = '*******@gmail.com'
    application.config['MAIL_PASSWORD'] = '*******'
    application.config['MAIL_DEFAULT_SENDER'] = ('APPNAME', '******@gmail.com')
    application.config['MAIL_SERVER'] = 'smtp.gmail.com'
    application.config['MAIL_PORT'] = 465
    application.config['MAIL_USE_SSL'] = True
    application.config['MAIL_USE_TLS'] = False

    from . import models

    db.init_app(application)

    with application.app_context():
        from . import app
        db.create_all()
    return application

下面是我的 app.py 的代码

from flask import current_app as app
from . import db
from .models import User
from flask_user import UserManager, SQLAlchemyAdapter, login_required


db_manager = SQLAlchemyAdapter(db, User)

user_manager = UserManager(db_manager, app)


@app.route('/')
def index():
    return ' welcome in the unprotected route'


@app.route('/profile')
@login_required
def profile():
    return 'you are in the procteted route '

你好，我也有同样的经历。 我将 Flask_user 更改为 0.6.13 版，它运行良好。 卸载您拥有的flask_user版本并使用pip install FLASK_USER==0.6.13
