密码保护

Posted 2020-10-18 黄向薇

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\'
    _password = db.Column(db.String(200),nullable=False)

 

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):  #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

 

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):

 

def sign_in():
    if request.method == \'GET\':
        return render_template(\'sign_in.html\')
    else:
        username = request.form.get(\'username\')
        password1 = request.form.get(\'password\')
        user = User.query.filter(User.username == username).first()
        if user:
            if user.check_password(password1):
                session[\'user\']=username
                session[\'userid\']=user.id
                session.permanent = True
                return redirect(url_for(\'base\'))
            else:
                return \'密码错误\'
        else:
            return \'用户名不存在\'
