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.密码验证的方法：
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):
from werkzeug.security import generate_password_hash,check_password_hash
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): 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(‘/login2/‘, methods=[‘GET‘,‘POST‘]) def login2(): if request.method==‘GET‘: return render_template(‘login2.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‘)) else: return "密码错误，请重新输入。" else: return "用户名不存在！"
