php - Laravel 的 ajax 演示，一步一步

Question

我认为这段代码有很多错误。我需要的是创建一个表单，执行 XHR 提交到 Controller ，获取数据，发送到模型，检查验证，使用验证输出返回到 Controller ，然后发送到 View 消息“错误或成功”

routes.php

Route::get('checkValidationEmail', 'HomeController@checkValidationEmail');

---

<?php
echo Form::open(array('url' => 'checkValidationEmail', 'class' => 'form_notify'));
echo Form::text('Email', Input::old('Email'),  array('placeholder'=>'Email', 'class' => 'hg'));
echo Form::close() 
?>

<a href="#" class="send_email"> Notify Me!</a>

好的，这工作正常，接下来，问题开始了。

AJAX

<script>
    $(function () {
        $(".send_email").click(function () {
            email = $('.hg').val();

            $.ajax({
                type: "POST",
                url: 'checkValidationEmail', //what is the correct url?
                data: {
                    email: email
                }
            }).done(function (msg) {
                alert(msg);
            });

        });
    });
</script>

500 错误:

{"error":{"type":"Symfony\\Component\\HttpKernel\\Exception\\MethodNotAllowedHttpException","message":"","file":"C:\\VertrigoServ\\www\\laravel\\vendor\\laravel\\framework\\src\\Illuminate\\Routing\\Router.php","line":1439}}

Controller

class HomeController extends BaseController {
       public function checkValidationEmail() {
           //how to get the data from form and pass to the model, more exactly validate($input)

                   if ($validation) {
                      return true;  
                   }
                   else {
                      return 'incorrect email'; //how send this message to the view?
                   }
       }
}

型号

class Home extends Eloquent {

    protected $table = 'emails';

    public function validate($input) {
       //validations
    }

}

Answer 1

在您的 route ，您将 checkValidationEmail 定义为 GET 请求，并且从您的 ajax 中，您尝试将其作为 POST 请求访问。所以这将抛出MethodNotAllowedHttpException。所以你必须改变你的路线，

Route::get('checkValidationEmail', 'HomeController@checkValidationEmail');

至，

Route::post('checkValidationEmail', 'HomeController@checkValidationEmail');

或者，

Route::any('checkValidationEmail', 'HomeController@checkValidationEmail');
