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
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):
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(20)) @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("/login",methods=["GET","POST"]) def login(): if request.method == "GET": return render_template("login.html") else: usern = request.form.get("usern") passw = request.form.get("userp") 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("first")) else: return "密码错误,请重新输入!" else: return "用户名不存在!"
