Laravel 4 regex:pattern 密码验证无效

Question

我正在尝试使用 regex:pattern 验证来检查我在 Laravel 4 中的密码强度。我正在按照以下方式尝试它，但如果我的 $validator 验证通过，它总是在 return 中给我 'Password is weak'。

public function checkPassStrength(){
    $password = Input::get('password');
    $validator = Validator::make(Input::all(), array(
        'password' => 'alpha_dash|min:6'
    ));
    $niceNames = array(
        'password' => 'Password'
    );
    $validator->setAttributeNames($niceNames);
    if($validator->fails()) {
        return Response::json(array('valid' => false, 'msg' => $validator->messages()->first('password')));
    } else {
        $strong = Validator::make(Input::all(), array(
            'password' => array('regex:/^(?=.*[A-Z])(?=.*[!@#$&*])(?=.*[0-9])(?=.*[a-z])$/')
        ));
        $medium = Validator::make(Input::all(), array(
            'password' => array('regex:/^(?=.*[A-Z])(?=.*[0-9])(?=.*[a-z])$/')
        ));
        if($strong->passes()){
            return Response::json(array('valid' => false, 'msg' => 'Password is strong'));
        } elseif($medium->passes()){
            return Response::json(array('valid' => false, 'msg' => 'Password is medium'));
        } else {
            return Response::json(array('valid' => false, 'msg' => 'Password is weak'));
        }

    }
}

Lookahead 是一个 zerolength 断言，在正则表达式末尾添加 .+：

/^(?=.*[A-Z])(?=.*[!@#$&*])(?=.*[0-9])(?=.*[a-z]).+$/

或者，如果您想将长度限制在 8 到 20 个字符之间：

/^(?=.*[A-Z])(?=.*[!@#$&*])(?=.*[0-9])(?=.*[a-z]).{8,20}$/
