如何在没有表格的情况下上传文件

问题描述：

我的控制器接收发布数据.它不是来自Symfony生成的表单，而是来自使用FormData的AngularJS自定义表单.

my controller receives post data. It's not from a Symfony generated form, but from an AngularJS custom form using FormData.

正常参数通常在请求参数包中接收，但是如何获取上载的文件?我需要手动执行与表单handleRequest相同的操作吗?

The normal parameters are received normally in the request parameter bag, but how do I get the file that is uploaded? Do I need to manually do the same that the form's handleRequest does?

我的文档与烹饪书文章相同.

因此，我需要从发布请求中获取一个UploadFile，以在文档实体上调用此方法:

So I need to get an UploadFile from the post request to call this method on the document entity:

public function setFile(UploadedFile $file = null)

如何在Symfony 2中手动接收上传(不以任何方式使用表单生成器)?

How do I receive a upload manually in Symfony 2 (without using the form builder in any way)?

答

请求具有FileBag，类似于ParameterBag

The Request has a FileBag, similar to the ParameterBag

因此，我可以使用以下命令轻松获得指定的文件:

So I could get the file specified easily with:

$data = $this->getRequest()->request->all();
$file = $this->getRequest()->files->get('file');

并按食谱中的原样使用文档:

and use the document as is from the cookbook:

$document = new Document();
$document->setFile($file);
$lead->setDocument($document);
