【问题描述】:
我已经配置了SECURITY_PASSWORD_SALT 并使用了“bcrypt”。但是每次我重新加载页面print encrypt_password('mypassword')都会打印不同的值,所以我无法通过verify_password(form.password.data, user.password)验证用户输入的密码。
但我可以从烧瓶安全内置登录视图登录
这是演示encrypt_password的奇怪行为的代码:
from flask import Flask, render_template
from flask.ext.sqlalchemy import SQLAlchemy
from flask.ext.security import Security, SQLAlchemyUserDatastore, \
UserMixin, RoleMixin, login_required
from flask.ext.security.utils import encrypt_password, verify_password
# Create app
app = Flask(__name__)
app.config['DEBUG'] = True
app.config['SECRET_KEY'] = 'super-secret'
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite://'
app.config['SECURITY_PASSWORD_HASH'] = 'sha512_crypt'
app.config['SECURITY_PASSWORD_SALT'] = 'fhasdgihwntlgy8f'
# Create database connection object
db = SQLAlchemy(app)
# Define models
roles_users = db.Table('roles_users',
db.Column('user_id', db.Integer(), db.ForeignKey('user.id')),
db.Column('role_id', db.Integer(), db.ForeignKey('role.id')))
class Role(db.Model, RoleMixin):
id = db.Column(db.Integer(), primary_key=True)
name = db.Column(db.String(80), unique=True)
description = db.Column(db.String(255))
class User(db.Model, UserMixin):
id = db.Column(db.Integer, primary_key=True)
email = db.Column(db.String(255), unique=True)
password = db.Column(db.String(255))
active = db.Column(db.Boolean())
confirmed_at = db.Column(db.DateTime())
roles = db.relationship('Role', secondary=roles_users,
backref=db.backref('users', lazy='dynamic'))
# Setup Flask-Security
user_datastore = SQLAlchemyUserDatastore(db, User, Role)
security = Security(app, user_datastore)
# Create a user to test with
@app.before_first_request
def create_user():
db.create_all()
user_datastore.create_user(email='matt@nobien.net', password='password')
db.session.commit()
# Views
@app.route('/')
#@login_required
def home():
password = encrypt_password('mypassword')
print verify_password('mypassword', password)
return password
# return render_template('index.html')
if __name__ == '__main__':
app.run()
【问题讨论】:
-
同样的原则适用; 意味着输出是随机的,因为包含随机盐。
-
@MartijnPieters 我在调用
encrypt_password后更新了要点和verify_password,但验证失败
