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‘ _password = db.Column(db.String(200),nullable=False)
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，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
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):
def sign_in(): if request.method == ‘GET‘: return render_template(‘sign_in.html‘) else: username = request.form.get(‘username‘) password1 = request.form.get(‘password‘) user = User.query.filter(User.username == username).first() if user: if user.check_password(password1): session[‘user‘]=username session[‘userid‘]=user.id session.permanent = True return redirect(url_for(‘base‘)) else: return ‘密码错误‘ else: return ‘用户名不存在‘
