访问烧瓶应用程序的配置给出＆＃34;模块对象没有属性__getitem __＆＃34;

Question

我正在尝试对我的烧瓶应用实施电子邮件身份验证，用户必须在完全在线注册过程中确认其电子邮件地址。我猜也许是我在app.py中设置配置的方式，或者我应该修改我的config.py？有什么想法吗？

这是我的app.py

....
import config

app = Flask(__name__)

# Import configuration
app.config.from_object(config.DevelopmentConfig)

# Initialize extensions
lm = LoginManager()
lm.session_protection = 'strong'
lm.init_app(app)
bootstrap = Bootstrap(app)
db = SQLAlchemy(app)
migrate = Migrate(app, db)
manager = Manager(app)
manager.add_command('db', MigrateCommand)
moment = Moment(app)
mail = Mail(app)
......

这是我的token.py

from itsdangerous import URLSafeTimedSerializer
import app


def generate_confirmation_token(email):
    serializer = URLSafeTimedSerializer(app.config['SECRET_KEY'])
    return serializer.dumps(email, salt=app.config['SECRET_PASSWORD_SALT'])

def confirm_token(token, expiration=3600):
    serializer = URLSafeTimedSerializer(app.config['SECRET_KEY'])
    try:
        email = serializer.loads(token, salt=app.config['SECRET_PASSWORD_SALT'], max_age=expiration)
    except:
        return False
    return email

这是由flask调试生成的错误日志

Answer 1

您有一个名为app的包，并导入名为config的模块。 app模块还定义了一个名为app的变量，该变量具有名为config的属性。您导入了错误的app。

from app import app
app.config['SECRET_KEY']
