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

 

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)#内部使用

    @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('/login2/', methods=['GET','POST'])
def login2():
    if request.method=='GET':
        return render_template('login2.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'] = usern
                    session['id'] = user.id
                    session.permanent=True
                    return redirect(url_for('index'))
                else:
                    return "密码错误，请重新输入。"
        else:
                    return "用户名不存在！"
