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' 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
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): # 定义一个外部使用的密码 return self._password @password.setter # 设置密码加密 def password(self, row_password): self._password = generate_password_hash(row_password) def check_password(self, row_password): # 定义一个反向解密的函数 result = check_password_hash(self._password, row_password) return result
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):
@app.route('/login', methods=['GET', 'POST']) def login(): if request.method == 'GET': return render_template('login.html') else: usern = request.form.get('username') passw = request.form.get('password') user = User.query.filter(User.username == usern).first() if user: if user.check_password(passw): session['user'] = usern session['id'] = user.id session.permanent = True return redirect(url_for('index')) # 重定向到首页 else: return u'password error' else: return u'username is not existed'
