燒瓶用戶：使用燒瓶郵件發送確認郵件失敗

Question

嗨，我正在使用 flask 用戶來模擬使用確認郵件和登錄進行注冊，但是在注冊階段，當用戶提交表單時，我收到錯誤消息，告訴我我沒有初始化燒瓶郵件，而在我的代碼中我得到了它的初始化所以我一直在尋找這個錯誤來自的潛在問題，但我並沒有真正找到，所以如果有人可以幫助我修復它，我把來自錯誤的回溯放在下面

我也將初始化文件的代碼放在下面初始化應用程序的位置

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 的代碼

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，我也有同樣的經歷。 我將 Flask_user 更改為 0.6.13 版，它運行良好。 卸載您擁有的flask_user版本並使用pip install FLASK_USER==0.6.13
