使用 FOSRestBundle 返回响应时无法找到模板

我正在使用 FOS Rest Bundle 构建 Api，问题是每次我尝试返回任何内容时都会收到错误消息：“无法找到模板”我真的不想渲染模板，而是序列化我拥有的实体。

这是我的代码：

路由.yml：

acme_api_register:
    pattern: /user
    defaults: { _controller: AcmeApiBundle:User:post, _format: json }
    requirements:
          _method: POST

控制器.php：

<?php

namespace Acme\ApiBundle\Controller;

use Acme\ApiBundle\Entity\Patient;
use Acme\ApiBundle\Entity\User;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use FOS\RestBundle\Controller\Annotations\View;

//use FOS\RestBundle\View\View;

    class UserController extends Controller
    {
        /**
         * @View()
         */
        public function postAction()
        {
            $user = new Patient();

            $user->setName("Daniel");
            $user->setLastName("My lastName");
            $user->setEmail("ple[email protected] /cdn-cgi/l/email-protection");

            return $user;
        }
    }

and my 应用程序/config.yml

sensio_framework_extra:
    view: { annotations: false}
    router: { annotations: true }

fos_rest:
    format_listener:
        rules:
            - prefer_extension: false
    routing_loader:
        default_format: json
    view:
        view_response_listener: force

我将非常感谢任何帮助！

发生这种情况是因为您可能正在使用浏览器来测试您的 API。如果您打开控制台检查器，您将看到浏览器发送到 API 的请求是什么。正如你所看到的Accept标题看起来像这样：

Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8

如您所见，第一个接受的格式是文本/html。这就是为什么我猜测您的应用程序正在尝试返回 HTML 响应，但它找不到模板！

所以我建议你禁用html如果不需要的话格式化并设置json作为默认格式。

fos_rest:
    param_fetcher_listener: true
    format_listener:
        rules:
            fallback_format: json
            prefer_extension: false
            priorities: [json, xml]
    view:
        view_response_listener: force
        formats:
            json: true
            xml: true
            jsonp: false
            rss: false
            html: false
        failed_validation: HTTP_BAD_REQUEST

通过这样的配置，您可以说您支持的唯一格式是json and xml并且，如果未指定，则使用json。 现在再次打开浏览器，您将获得 XML 形式的资源。那是因为Accept标题仍然是Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8。您的浏览器不知道您正在调用 Rest API 以及您的首选格式是什么:-)

为了测试您的 API，我建议您使用合适的客户端。如果您使用的是 Chrome，请查看高级 REST 客户端 http://chromerestclient.appspot.com/扩大。
