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
_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
@property
def password(self):#外部使用，取值
return self._password
@password.setter
def password(self, row_password):
self._password = generate_password_hash(row_password)
def check_password(self, row_password):#外部使用，赋值
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):
@app.route(‘/login/‘,methods=[‘GET‘,‘POST‘])
def login():
if request.method == "GET":
return render_template("login.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
sessionpermanent = True
return redirect(url_for(‘homepage‘))
else:
return ‘password error‘
else:
return ‘username is not existed‘
