Question

我对Symfony 3.2中的FOSRestBundle没什么问题。首先，让我展示一下配置和行动：

FOSRest conf：

fos_rest:
    versioning: true
    body_converter:
        enabled: true
        validate: true
        validation_errors_argument: validationErrors
    view:
        mime_types:
            json: ['application/vnd.service_name+json; charset=UTF-8', 'application/json; charset=UTF-8', 'application/json']
    param_fetcher_listener: true
    body_listener:
        decoders:
            json: fos_rest.decoder.json
    routing_loader:
        default_format: json
    format_listener:
        enabled: true
    serializer:
        serialize_null: true

路由：

api_panel_external_address_services_get:
    path: /addresses/{addressId}/services
    methods: GET
    defaults:
        _controller: AppBundle:Api/ManagementPanel/External/Address:getServices
        _format: json
    requirements:
        addressId: \d+

动作：

 /**
 * @ApiDoc(
 *  section="Panel/External",
 *  resource=true,
 *  description="Get external services",
 *  requirements={
 *    {"name"="addressId", "dataType"="string", "description"="External address id"}
 *  },
 *  statusCodes={
 *      200="Returned when success",
 *      400="Returned when data has errors (did not pass validation)",
 *      404="Returned when address was not found",
 *  }
 * )
 *
 * @ParamConverter("externalAddress", class="Company\Model\ExternalAddress", options={"mapping"={"addressId":"id"}})
 */
public function getServicesAction(ExternalAddress $externalAddress, ConstraintViolationListInterface $validationErrors): Response
{
    if ($validationErrors->count())
    {
        $view = $this->view($validationErrors, Response::HTTP_BAD_REQUEST);

        return $this->handleView($view);
    }

    $externalServices = $externalAddress->getExternalServices();

    $services = [];
    foreach ($externalServices as $externalService)
    {
        $services[] = [
            'id'                  => $externalService->getId(),
            'name'                => $externalService->getName(),
        ];
    }

    return $this->handleView($this->view($services, Response::HTTP_OK));
}

问题：当我去路线/api/v1/panel/external/addresses/801/services时，我在不同的环境中会遇到不同的错误。

邮差：（代码：400）：Could not decode JSON, syntax error - malformed JSON.

浏览器： "code":415,"message":"Unsupported Media Type","exception":[{"message":"The format \"\" is not supported for deserialization."

但是当我删除时 , ConstraintViolationListInterface $validationErrors 和

    if ($validationErrors->count())
    {
        $view = $this->view($validationErrors, Response::HTTP_BAD_REQUEST);

        return $this->handleView($view);
    }

来自Action，一切正常，我得到了JSON响应。

我做错了吗？我希望在FOSRestBundle文档中使用此$validationErrors变量。

希望我能在这里得到一些帮助。

好的，我在代码中找到了答案。 这是http方法GET，当我没有提供任何内容主体（json）时，会出现错误。如果您使用get方法，则应从操作中删除$validationErrors。如果$method === 'GET'，IMO应该检查FOSRestBundle。如果没有它的混乱，但仍然是完美的意义 - 当你的方法是GET时，你不需要验证身体。

希望这可以节省一些人的搜索时间。

FOSRestBundle无法解析JSON
