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):
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
@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
@app.route(‘/login/‘, methods=[‘GET‘, ‘POST‘])
def login():
if request.method == ‘GET‘:
return render_template(‘login.html‘)
else:
username = request.form.get(‘username‘)
password = request.form.get(‘password‘)
user = User.query.filter(User.username == username).first()
if user:
if user.check_password(password):
session[‘user‘] = username
session[‘user_id‘]=user.id
session.permanent = True
return redirect(url_for(‘daohang‘))
else:
return ‘error username or password‘
