Magento 2 - 来自 Javascript 的请求返回状态代码 302

Question

我正在通过 XMLHttpRequest 发送一个带有数据的 POST 请求。我得到的响应确实有状态代码 302。

Javascript函数：

function createCSV() {
let xhttp = new XMLHttpRequest();
xhttp.open("POST", '', false);
xhttp.setRequestHeader("Content-type", "application/json");
xhttp.send(JSON.stringify(formDataObject));}

回复：

Request URL: http://localhost:8888/magento2/delivery/inputform/national
Request Method: POST
Status Code: 302 Found
Remote Address: [::1]:8888
Referrer Policy: no-referrer-when-downgrade

布局

        </referenceContainer>
    </body>
</page>

这是我的街区

<?php
 namespace Magento\VersandForm\Block;

 class Send extends \Magento\Framework\View\Element\Template
 {
   public function 
   __construct(\Magento\Framework\View\Element\Template\Context 
   $context)
{
    parent::__construct($context);
}

/**
 * Returns description for Tooltip
 * @return string
 */
public function getRequiredFieldsDescription(){
    return 'Diese Felder müssen ausgefüllt sein';
}

}

这是我的控制器

<?php
namespace Magento\VersandForm\Controller\Inputform;

use Magento\Framework\Controller\ResultFactory;

class National extends \Magento\Framework\App\Action\Action
{
    protected $_pageFactory;
    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\View\Result\PageFactory $pageFactory)
    {
        $this->_pageFactory = $pageFactory;
        return parent::__construct($context);
    }

    /**
     * Booking action
     *
     * @return void
     */
    public function execute()
    {
        // 1. POST request : Get Data From Javascript
        $post = (array) $this->getRequest()->getPost();
    }
}

为什么 Magento 要重定向我。如果您遇到过此类错误，请提供信息。

找到解决方案：

问题不在控制器中。问题是我用 Javascript 发送的请求。似乎 Magento 需要 Header“X-Requested-With: XMLHttpRequest”。所以只需将它添加到您的请求

function createCSV() {
let xhttp = new XMLHttpRequest();
xhttp.open("POST", '', false);
xhttp.setRequestHeader("Content-type", "application/json");
xhttp.setRequestHeader("X-Requested-With", "XMLHttpRequest");
xhttp.send(JSON.stringify(formDataObject));}
