注册加密及登录验证的解密

flask中对数据的加密使用generate_password_hash和check_password_hash

注册时的加密

@user_blueprint.route('/register/', methods=['GET', 'POST'])
def register():
    if request.method == 'GET':
        return render_template('register.html')
    if request.method == 'POST':
        username = request.form.get('username')
        password = request.form.get('password')
        if not all([username, password]):
            return render_template('register.html')
        # 保存注册信息
        user = User()
        user.username = username

        user.password = generate_password_hash(password)
        db.session.add(user)
        db.session.commit()
        return redirect(url_for('user.login'))

登录时的解密

@user_blueprint.route('/login/', methods=['GET', 'POST'])
def login():
    if request.method == 'GET':
        return render_template('login.html')

    if request.method == 'POST':
        username = request.form.get('username')
        password = request.form.get('password')
        if not all([username, password]):
            return render_template('login.html')

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

        if user and check_password_hash(user.password,password):
            session['login_status'] = 1
            return redirect(url_for('user.index'))
        else:
            return render_template('login.html')
