1.更新User對象，設置對內的_password

class User(db.Model):

??? __tablename__ = 'user'?

?? ?_password = db.Column(db.String(200), nullable=False) #內部使用

?

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))

?

2.編寫對外的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，賦值

??????? self._password = generate_password_hash(row_password)

?

from werkzeug.security import generate_password_hash, check_password_hash
@propertydef password(self):return self._password@password.setterdef password(self, row_password):self._password = generate_password_hash(row_password)

?

3.密碼驗證方法：

? ? def check_password(self, row_password): #密碼驗證

??????? result = check_password_hash(self._password,row_password)

??????? return result

?

def check_password(self, row_password):result = check_password_hash(self._password, row_password)return result

?

4.登錄驗證：

? ? ? ??password1 = request.form.get('password')

? ? ? ? user = User.query.filter(User.username == username).first()

??????? if user:

??????????? if user.check_password(password1):

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'] = usernsession['user_id'] = user.idsession.permanent = Truereturn redirect(url_for('index'))else:return u'password error'else:return u'error username'
