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

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)

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

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):

from werkzeug.security import generate_password_hash, check_password_hash

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)
    nickname = db.Column(db.String(50))


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

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

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

@app.route('/login',methods=['GET','POST'])
def login():
    if request.method =='GET':
        return render_template('denglu.html')
    else:
        name = request.form.get('name')
        passw = request.form.get('password')
        user = User.query.filter(User.username == name).first()
    if user:
       if user.check_password(passw):
            session['user'] = name
            session['userid'] = user.id
            session.permanent = True
            return redirect(url_for('manhua'))
       else:
           return "密码错误！"
    else:
        return "用户名不存在！"
