1.更新User对象，设置对内的_password

class User(db.Model):

__tablename__ = 'user'

_password = db.Column(db.String(200), nullable=False) #内部使用

class User(db.Model):
    __tablename__ = 'user'
    id = db.Column(db.Integer,primary_key=True,autoincrement=True)
    username = db.Column(db.String(20),nullable=False)
    _password = db.Column(db.String(200), nullable=False) #内部使用

2.编写对外的password

from werkzeug.security import generate_password_hash, check_password_hash

@property

def password(self): #外部使用，取值

return self._password

@password.setter

def password(self, row_password):#外部使用，赋值

self._password = generate_password_hash(row_password)

@property
def password(self):
    return self._password

@password.setter
def password(self, row_password):
    self._password = generate_password_hash(row_password)

3.密码验证的方法：

def check_password(self, row_password): #密码验证

result = check_password_hash(self._password,row_password)

return result

def check_password(self, row_password):
    result = check_password_hash(self._password, row_password)
    return result

4.登录验证：

password1 = request.form.get('password')

user = User.query.filter(User.username == username).first()

if user:

if user.check_password(password1):

@app.route('/login/',methods=['GET','POST'])
def login():
    if request.method=='GET':
        return render_template('login.html')
    else:
        username = request.form.get('username')
        password = request.form.get('password')
        user = User.query.filter(User.username==username).first()
        if user:
            if user.check_password(password):
                session['user'] = username
                session['id'] = user.id
                session.permanent = True
                return redirect(url_for('home'))
            else:
                return 'Password error'
        else:
            return 'Username inexistent'
