密码保护

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

 

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)

 

from werkzeug.security import generate_password_hash, check_password_hash

@propertydef password(self):return [email protected]def password(self, row_password):self._password = generate_password_hash(row_password)

 

3.密码验证方法：

    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):

def login():if request.method == 'GET':return render_template('login.html')else:usern = request.form.get('username')passw = request.form.get('password')user = User.query.filter(User.username == usern).first()if user:if user.check_password(passw):session['user'] = usernsession['user_id'] = user.idsession.permanent = Truereturn redirect(url_for('index'))else:return u'password error'else:return u'error username'
