密码保护
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
代码如下:
class User(db.Model): __tablename__ = 'user' # 建立一个表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) image = db.Column(db.String(100)) say = db.Column(db.String(50))
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)
代码如下:
@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)
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
代码如下:
def check_password(self,row_password): 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):
代码如下:
@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() #判断用户名是否存在 if user: # if user.password==passw: if user.check_password(passw): session['user'] = usern#字典键值 session['userid'] = user.id session.permanent = True return redirect(url_for('index')) else: return u' password error' else: return u' username not existed'
运行结果:
