我在里面制作了一个Bundle和一个REST控制器。 "索引"方法以JSON格式返回数组,没关系:
MyBundle /控制器/原料药/休息/ BaconController.php
class BaconController extends Controller implements ClassResourceInterface
{
/**
* @var Request $request
* @return array
* @Rest\View
*/
public function cgetAction(Request $request)
{
$mediaType = $request->attributes->get('media_type');
$format = $request->getFormat($mediaType);
my_dump($format);
return array(
array("id" => 1, "title" => "hello",),
array("id" => 2, "title" => "there",),
);
}
}
MyBundle /资源/配置/ API / routing_rest.yml
my_api_rest_bacon:
type: rest
resource: "MyBundle:Api/Rest/Bacon"
name_prefix: api_rest_bacon_
prefix: /my/bacon
因此,此时JSON结果将完美返回:
mysite.com/app_dev.php/api/my/bacon/bacons.json
返回我的数组。
但现在我需要让我的控制器生成带有数据的PDF。所以我希望它在我打电话时返回PDF文件:
mysite.com/app_dev.php/api/my/bacon/bacons.pdf
我找到了一些半手册:RSS view handler,RSS config.ynal,CSV issue with answers。并试图做出类似的东西:
我已将这些行添加到
的Symfony /应用/配置/ config.yml
framework:
[...some old stuff here...]
request:
formats:
pdf: 'application/pdf'
fos_rest:
body_converter:
enabled: true
format_listener:
rules:
# Prototype array
-
# URL path info
path: ~
# URL host name
host: ~
prefer_extension: true
fallback_format: html
priorities: [html,json]
-
path: ~
host: ~
prefer_extension: true
fallback_format: pdf
priorities: [pdf]
view:
# @View or @Template
view_response_listener: force #true
formats:
json: true
pdf: true
xls: true
html: false
templating_formats:
pdf: false
xls: false
mime_types: {'pdf': ['application/pdf']}
routing_loader:
default_format: html
param_fetcher_listener: true
body_listener: true
allowed_methods_listener: true
services:
my.view_handler.pdf:
class: Lobster\MyBundle\View\PdfViewHandler
my.view_handler:
parent: fos_rest.view_handler.default
calls:
- ['registerHandler', [ 'pdf', [@my.view_handler.pdf, 'createResponse'] ] ]
MyBundle /视图/ PdfViewHandler.php
namespace Lobster\MyBundle\View;
use FOS\RestBundle\View\View;
use FOS\RestBundle\View\ViewHandler;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
class PdfViewHandler
{
public function createResponse(ViewHandler $handler, View $view, Request $request, $format)
{
my_dump('pdf createResponse started');
$pdf = "some pdf";
return new Response($pdf, 200, $view->getHeaders());
}
}
所以现在我打电话
mysite.com/app_dev.php/api/my/bacon/bacons.pdf
我看到错误An Exception was thrown while handling: Format html not supported, handler must be implemented
,我的函数my_dump
保存到有关文件格式的文本文件信息:它是html
,而不是pdf
。
pdf createResponse
也没有用。为什么呢?
答案 0 :(得分:7)
所以我找到了解决方案(我将介绍如何启用2种输出格式:PDF和XLS):
1)不需要config.yml
中的此部分:
framework:
[...some old stuff here...]
request:
formats:
pdf: 'application/pdf'
2 fos_rest.format_listener
中的config.yml
部分应如下所示:
format_listener:
rules:
-
path: '^/api/my/bacon.*\.xls$'
host: ~
prefer_extension: false
fallback_format: json
priorities: [xls, json]
-
path: '^/api/my/bacon.*\.pdf$'
host: ~
prefer_extension: false
fallback_format: json
priorities: [pdf, json]
-
path: ~
host: ~
prefer_extension: true
fallback_format: html
priorities: [html,json]
3)需要将service
部分添加到fos_rest
中的config.yml
fos_rest:
[...]
service:
view_handler: my.view_handler
4 services
中的config.yml
根部分应该看起来像
services:
my.view_handler.xls:
class: Lobster\MyBundle\View\XlsViewHandler
my.view_handler.pdf:
class: Lobster\MyBundle\View\PdfViewHandler
my.view_handler:
parent: fos_rest.view_handler.default
calls:
- ['registerHandler', ['xls', [@my.view_handler.xls, 'createResponse'] ] ]
- ['registerHandler', ['pdf', [@my.view_handler.pdf, 'createResponse'] ] ]
就是这样。现在它完美无缺

如果文件具有不同的数据内容,那么Controller也可以自己生成文件,并在BinaryFileResponse中返回结果。
