FOSRestBundle自定义视图处理程序未注册 [英] FOSRestBundle custom view handler not registering

问题描述

我正在尝试创建自定义处理程序，以将响应序列化为csv格式.

I'm trying to create custom handler for serializing response into csv format.

到目前为止，我一直在按照文档中的步骤进行操作( http://symfony.com/doc/master/bundles/FOSRestBundle/2-the-view-layer.html#custom-handler )，但是在调用扩展名为.csv的端点时我仍然收到错误:

So far I've been following the steps from documentation (http://symfony.com/doc/master/bundles/FOSRestBundle/2-the-view-layer.html#custom-handler), however when calling my endpoint with .csv extension I still get the error:

The format "csv" is not supported for serialization.

这是我的services.yml配置位:

api.csv_handler:
    class: ApiBundle\ViewHandlers\CsvViewHandler

api.view_handler:
    parent: fos_rest.view_handler.default
    calls:
        - ["registerHandler", ["csv", ["@api.csv_handler", "createResponse"]]]

在fos_rest下的config.yml中，我有这个:

view:
    mime_types: { 'csv': ['text/csv','text/plain'] }
    view_response_listener: 'force'
    formats:
        json: true
        xml:  true
        csv:  true
    templating_formats:
        html: true
format_listener:
    enabled: true
    rules:
        - { path: ^/, priorities: [ json, xml, csv ], fallback_format: json, prefer_extension: false }
        - { path: ^/api/doc, priorities: [ html ], fallback_format: html, prefer_extension: false }

CsvViewHandler类中的createResponse方法当前仅包含一些调试代码以验证其是否正常工作.

The createResponse method inside my CsvViewHandler class currently only contains some debug code to verify if it's working, which it isn't.

那我在这里想念什么?

推荐答案

您必须在FOSRest捆绑包配置中注册视图处理程序:

You have to register your view handler in FOSRest bundle configuration:

fos_rest:
    ...
    service:
        view_handler: my_bundle.view_handler
    ...



services:
    ...
    my_bundle.my_handler:
        class: MyBundle\View\MyHandler
    my_bundle.view_handler:
        parent: fos_rest.view_handler.default
        calls:
            - ['registerHandler', [ 'my_format', ["@my_bundle.my_handler", 'createResponse'] ] ]
    ...
