为 TYPO3 9.5 中的 404 页面设置 content-type HTTP header

Question

我正在使用 TYPO3 制作网络服务。前端的所有内容都应该是 JSON 和 HTTP header Content-Type: application/json，但是我无法更改 404 页面的 Content-Type header。无论我尝试什么，它总是 Content-Type: text/html; charset=utf-8。我该如何更改？

这是我的基本 page TypoScript 配置：

page = PAGE
page {
  config {
    disableAllHeaderCode = 1
    disablePrefixComment = 1
    xhtml_cleaning = 0
    admPanel = 0
  }
  10 = USER
  10 {
    userFunc = TYPO3\CMS\Extbase\Core\Bootstrap->run
    extensionName = MyExt
    pluginName = MyPlugin
    vendorName = MyVendor
  }
}

扩展程序使用 TYPO3\CMS\Extbase\Mvc\View\JsonView。

我已经尝试使用 config.additionalHeaders.10.header = Content-Type: application/json 添加 header。我还尝试将 [FE][pageNotFound_handling] 设置为 USER_FUNCTION:... 并在 PHP.

中设置 headers

我自己找到了解决方案。从 TYPO3 9.5 开始，默认页面未找到处理可以在站点配置中被覆盖：

errorHandling:
  -
    errorCode: 404
    errorHandler: PHP
    errorPhpClassFQCN: Vendor\MyExt\PageErrorHandler\PageNotFoundHandler

并且在 EXT:MyExt/Classes/PageErrorHandler/PageNotFoundHandler.php:

<?php
namespace Vendor\MyExt\PageErrorHandler;

use GuzzleHttp\Psr7\Response;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;
use TYPO3\CMS\Core\Error\PageErrorHandler\PageErrorHandlerInterface;

/**
 * Class PageNotFoundHandler
 */
class PageNotFoundHandler implements PageErrorHandlerInterface
{
    /**
     * Handle page error
     *
     * @param ServerRequestInterface $request
     * @param string $message
     * @param array $reasons
     * @return ResponseInterface
     */
    public function handlePageError(ServerRequestInterface $request, string $message, array $reasons = []): ResponseInterface
    {
        $response = new Response(404, ['Content-Type' => 'application/json'], '{"error":"Not found"}');
        return $response;
    }
}
