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) nickname = db.Column(db.String(50), nullable=True)
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
from werkzeug.security import generate_password_hash,check_password_hash # 定义属性:password: @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) # 检查密码 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):
@app.route(‘/login/‘, methods=[‘GET‘, ‘POST‘]) # 跳转登陆,methods定义它有两种请求方式 def login(): if request.method == ‘GET‘: return render_template(‘login.html‘) else: username = request.form.get(‘user‘) password1 = request.form.get(‘psw‘) user = User.query.filter(User.username == username).first() # 判断用户名是否存在 if user: if user.check_password(password1) : session[‘user‘]=username session[‘id‘]=user.id session.permanent = True return redirect(url_for(‘moban‘)) else: return ‘密码错误‘ else: return ‘用户名不存在‘
