Python 发送curl请求时，使用bcrypt driver.db进行Eve身份验证时出错

我使用bcrypt对我的资源进行身份验证，并在mydatabase中使用用户名和密码存储帐户。我已将密码以哈希形式手动存储在数据库中，如下所示：

curl -u username 127.0.0.1:5000/people

我启动了python bash并输入了以下代码：

import bcrypt
password = u'passwordtobehashed'
password_hashed = bcrypt.hashpw(password, bcrypt.gensalt())
print (password_hashed)

然后，我复制了打印输出，并通过POST请求将其存储在account表中（没有身份验证）：

我使用SQLAlchemy，eve也是最新的（版本：0.7.1）。 例如，我请求使用Bcrypted身份验证的人员资源，如下所示：

curl -u username 127.0.0.1:5000/people

然后我输入密码，出现以下错误：

 File "/home/vagrant/erpghost/restapi/oldtrivial.py", line 57, in check_auth
   accounts = app.data.driver.db['account']
AttributeError: 'SQLAlchemy' object has no attribute 'db'

由于某些原因，db属性不可用。我还尝试使用Eve.app.data.driver.db，并尝试从flask导入当前的_应用程序，但都没有成功

这是我的代码：

OldTriple.py

tables.py

设置.py

希望有人能帮我。

以下几点应该行得通：

from flask import current_app
from tables import Account

# ...

def check_auth(...):
    session = current_app.data.driver.session
    return session.query(Account) \
                  .filter(Account.username == username,
                          Account.password == hashed_password) \
                  .count() > 0

我猜你试着模仿我的代码？这是为了使用MongoDB而不是SQLAlchemy

    __abstract__ = True
    _created = Column(DateTime, default=func.now())
    _updated = Column(DateTime, default=func.now(), onupdate=func.now())
    _etag = Column(String(40))


class People(CommonColumns):
    __tablename__ = 'people'
    _id = Column(Integer, primary_key=True, autoincrement=True)
    firstname = Column(String(80))
    lastname = Column(String(120))
    fullname = column_property(firstname + " " + lastname)


class Roles(CommonColumns):
    __tablename__ = 'roles'
    _id = Column(Integer, primary_key=True, autoincrement=True)
    role = Column(String(80))

    __tablename__ = 'account'
    _id = Column(Integer, primary_key=True, autoincrement=True)
    username = Column(String(50), nullable=False, unique=True)
    password = Column(String(200), nullable=False)
    roles = relationship("Roles", backref="account")
    roles_id = Column(Integer, ForeignKey('roles._id'))
