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):
# 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) # _password = db.Column(db.String(20),nullable=False) #内部使用 nickname=db.Column(db.String(50)) @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) def check_password(self, row_password): result = check_password_hash(self._password, row_password) return result #登录 @app.route(‘/login/‘,methods={‘GET‘,‘POST‘}) def login(): if request.method==‘GET‘: return render_template(‘login.html‘) else: username = request.form.get(‘username‘) # 获取form中的数据 password = request.form.get(‘password‘) nickname = request.form.get(‘nickname‘) user = User.query.filter(User.username == username).first() if user: if user.check_password(password): #检查密码 session[‘user‘] = username session[‘userid‘]=user.id session.permanent=True return redirect(url_for(‘index‘)) # 返回到首页 else: return u‘error password‘ #输出错误 else: return u‘username error‘
