Laravel Validator总是失败

Question

我在电子邮件字段上有一个简单的验证程序。通过JQuery，我运行Laravel控制器来检查输入。但是它总是失败。.

为了使内容更清楚，我将else留空了。

我也收到此错误。找到一些与此有关的stackoverflow主题，并尝试使用代码中看到的解决方案，但这没有帮助。

422 (Unprocessable Entity)

我的控制器功能：

public function send_mail(Request $request, VendorProfile $profile_id){
        $profile= $profile_id;

        $email = $request->input('contact_e_mail');
        $contact_first_name = $request->input('contact_first_name');
        $email_profile = $profile->email;
        $name_profile = $profile->name;

        $rules = [
            'contact_e_mail' => 'required|email',
        ];

        $validator = Validator::make($request->all(), $rules);

        if ($validator->fails()) {
            if($request->ajax())
            {
                return response()->json(array(
                    'success' => false,
                    'message' => 'There are incorect values in the form!',
                    'errors' => $validator->getMessageBag()->toArray(),
                ), 422);
            }

            $this->throwValidationException(
                $request, $validator
            );
        } else {
        }
    }
