Flask WTForms 自定义验证器始终显示 'Username or password is incorrect'

Question

我正在尝试为登录表单设置自定义验证器，但它总是显示 'username and password are incorrect' 即使我输入了有效验证器。有什么建议么？这是我的代码：

def login_check(form,field):
    user_email = User.query.filter_by(email=form.email.data).first()
    if user_email is None:
        raise ValidationError('Username or password is incorrect')
    elif not check_password_hash(field.data, user_email.password):
        raise ValidationError('Username or password is incorrect')

class LoginForm(FlaskForm):

    email = StringField('Email', validators=[InputRequired(), Email()])
    password = PasswordField('Password', validators=[InputRequired(),login_check])
    submit = SubmitField('Login')

Answer 1

我用 passlib.hash pbkdf2_sha256 替换了 werkzeug.security 现在它可以工作了，我不知道为什么会这样

代码

from passlib.hash import pbkdf2_sha256

def login_check(form,field):
user_email = User.query.filter_by(email=form.email.data).first()
if user_email is None:
    raise ValidationError('Username or password is incorrect')
elif not pbkdf2_sha256.verify(field.data, user_email.password):
    raise ValidationError('Username or password is incorrect')

@app.route('/register', methods=['POST','GET'])
def register():
    reg_form = RegistrationForm()
    if reg_form.validate_on_submit():
        password = reg_form.password.data
        hased_pass = pbkdf2_sha256.hash(password)
        user = User(name=reg_form.name.data, lastname=reg_form.lastname.data,
                email=reg_form.email.data, password=hased_pass)
        db.session.add(user)
        db.session.commit()
        login_user(user)
        flash(f'Welcome {user.name}, Your account have been created')
        return redirect(url_for('index'))

Flask WTForms 自定义验证器始终显示 'Username or password is incorrect'

Flask WTForms custom validator is always showing 'Username or password is incorrect'
