密码保护

Posted 2020-10-18 冯耀娴

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

#创建用户模型
class User(db.Model):
    __table__name = ‘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

    @property
    def password(self): #外部使用
        return self._password

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

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

#登录
@app.route(‘/login/‘ , methods=[‘GET‘,‘POST‘])
def login():
    if request.method == ‘GET‘  :
        return render_template(‘login.html‘)
    else:
        username = request.form.get(‘username‘)# 获取form中的数据
        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(‘index‘))
        else:
            return u‘password error‘
    else:
        return u‘username is not existed.‘
        return redirect(url_for(‘index‘))  # 返回首页
