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), nullable=True)

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

from werkzeug.security import generate_password_hash,check_password_hash


# 定义属性:password:
@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)


# 检查密码
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‘])  # 跳转登陆,methods定义它有两种请求方式
def login():
    if request.method == ‘GET‘:
        return render_template(‘login.html‘)
    else:
        username = request.form.get(‘user‘)
        password1 = request.form.get(‘psw‘)
        user = User.query.filter(User.username == username).first()  # 判断用户名是否存在
        if user:
           if user.check_password(password1) :
               session[‘user‘]=username
               session[‘id‘]=user.id
               session.permanent = True
               return redirect(url_for(‘moban‘))
           else:
               return ‘密码错误‘
        else:
            return ‘用户名不存在‘
