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_hashapp=Flask(__name__) app.config.from_object(config) db=SQLAlchemy(app)# 创建用户模型 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))
