密碼保護

1.更新User對象，設置對內的_password

class User(db.Model):

    __tablename__ = 'user' 

    _password = db.Column(db.String(200), nullable=False) #內部使用

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(20), nullable=False)
    _Password=db.Column(db.String(200), nullable=False)#內部使用
    Telphone = db.Column(db.String(20), nullable=True)

 

2.編寫對外的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，賦值

        self._password = generate_password_hash(row_password)

 

 @property
    def Password(self):
        return self._Password#取值

    @Password.setter
    def Password(self,row_password):
        self._Password=generate_password_hash(row_password)

3.密碼驗證的方法：

    def check_password(self, row_password): #密碼驗證

        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.登陸驗證：

        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'])
def login():
    if request.method == 'GET':
        return render_template('login.html')
    else:
        usern = request.form.get('Username')
        passn1 = request.form.get('Password')
        user = User.query.filter(User.Username == usern).first()
        if user:
            if user.check_password(passn1):
                session['user'] = usern
                return redirect(url_for('index'))
            else:
                return '密碼錯誤'
                # return window.alert("密碼錯誤")
        else:
            # return window.alert("用戶名不存在")
            return '用戶名不存在'
