Symfony 返回带有FOSRestBundle的响应时找不到模板

我使用FOS Rest Bundle构建Api，问题是每次尝试返回任何内容时，都会收到错误消息：“找不到模板”，我并不真的想呈现模板，而是想序列化我拥有的实体

这是我的密码：

我认为您使用了错误的控制器，请尝试改用FOSRestController。控制器代码应该是这样的

<?php

    namespace Acme\ApiBundle\Controller;

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


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

            $user->setName("Daniel");
            $user->setLastName("My lastName");
            $user->setEmail("pleasework@gmail.com");

            return $user;
        }
    }

如果您遵守中解释的规则，FOSRest可以自动为您生成路由

请慢慢看，因为如果我看一下您的代码，很明显您没有这样做。

我知道您在评论中说要放弃，但是如果您仍然想构建REST api，您应该尝试一下。 我认为您的

config.yml

是错误的。您必须指定页面格式的优先级，以确保第一个选择的是

json

（即使您在路由中编写了它，也不够）

尝试将您的配置文件更改为如下所示：

#...
fos_rest:
    view:
        view_response_listener: force
    format_listener:
        default_priorities: ['json', 'html', '*/*']
        fallback_format: json
        prefer_extension: true
#...

下面是一篇关于如何构建正确的REST Api的非常好的文章：

发生这种情况是因为您可能正在使用浏览器测试API。如果打开console inspector，您将看到浏览器向API发送的请求。正如您所看到的，Accept标题看起来像：

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text/html。这就是为什么我猜您的应用程序试图返回HTML响应，但它找不到模板

因此，如果不需要，我建议您禁用html格式，并将json设置为默认格式

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

在这种配置中，您的意思是您支持的唯一格式是json和xml，如果未指定任何格式，请使用json。 现在再次打开浏览器，您将获得XML格式的资源。这是因为Accept头仍然是

Accept:text/html、application/xhtml+xml、application/xml；q=0.9，图像/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：-）

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，请查看扩展。

您好，我尝试将父控制器类更改为FOSRestController，但是，错误仍然存在，然后我意识到您的答案与我写的“positionAction”而不是“postAction”有不同的操作。如果我改变这个，我会得到“URI的控制器”\/user\“不可调用”错误我改变了答案。。。再说一遍，请确保你读了我确实读过的文件，但这些文件都不适合我，自动生成的路线也找不到。。。我已经完成了，这只是浪费时间，我最后用的是普通交响乐。此外，如果我坚持使用文档，就不会提到FOSRestController，而是提到FOSRestController和son。。。谢谢你的语气；）但是没有投票否决；）仅供参考：路由文档的链接已断开。更新到可能重复的
