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)#内部使用 nickname = db.Column(db.String(50))
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 return self._password @password.setter def password(self, row_password): 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
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):
if user: if user.check_password(password):
