Question

如何在request->file中自定义文件上传期间使用$request = Request::createFromGlobals();从Symfony 2.8检索pathName到控制器操作，以便从文件中读取数据（我不需要将文件保存到数据库）。如何参考"pathName"？我无法从上传的文件中检索信息，即我无法获取"pathName"。

另外，如何与文件一起提交自定义文件名。这可能吗？

//Controller
<?php

namespace CrmBundle\Controller;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;

/**
 * @Route("/mip")
 */
class MoInPlController extends Controller {

    /**
     * Plots profits, etc..
     *
     * @Route("/m1i1p1d", name="m1i1p1d")
     * @Method({"GET","POST"})
     */
public function m1i1p1dAction()
{  

    $msg[]="";

    $request = Request::createFromGlobals(); 

 if ($request->files->get('fileToUpload')) { 
        if($request->request->get('nameF') ) { $nameF = $request->get('nameF'); }
        print_r('<br> 1. request->files->get(fileToUpload) = <pre>');       var_dump($request->files->get('fileToUpload') ); print_r('</pre>');

        $ftoup=$request->files->get('fileToUpload');
        print_r('<br> 2, ftoup = <pre>'); var_dump( $ftoup ); print_r('</pre>');
        print_r('<br> 3, get_object_vars (ftoup) = <pre>'); var_dump( get_object_vars($ftoup) ); print_r('</pre>'); //empty array
        print_r('<br> 4, ftoup[pathName] = <pre>'); var_dump( $ftoup["pathName"] ); print_r('</pre>'); //empty string

        $msg[]='<br> The file was submitted.';

        $strData = file_get_contents($ftoup["pathName"]); //does not work here
        $jsonData = json_decode($strData, true);

    } else {
        $msg[]='<br> Not upload yet.';
    }

    return $this->render( 'CrmBundle:moinpl:m1i1p1.html.twig',
            array( "mssgs"=>$msg ) ); 
} 
...}

Twig模板：

{% block body %}

<form name="crmbundle_moinpl_m1i1p1" method="post" action="/mip/m1i1p1d" enctype="multipart/form-data">
    <br> <input type="file" name="fileToUpload" id="fileToUpload">
    <br> Name of file for future refering: <input type="text" name="nameF">.  
    <br> <input type="submit" name="loadF" value="Add File" />
</form>

{％endblock％}

结果如下：

request->files->get(fileToUpload) =

object(Symfony\Component\HttpFoundation\File\UploadedFile)#1066 (7) {
  ["test":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
  bool(false)
  ["originalName":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
  string(12) "CompSit.json"
  ["mimeType":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
  string(24) "application/octet-stream"
  ["size":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
  int(3259)
  ["error":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
  int(0)
  ["pathName":"SplFileInfo":private]=>
  string(49) "C:\Bitnami\wampstack-5.6.20-0\php\tmp\php3FCA.tmp"
  ["fileName":"SplFileInfo":private]=>
  string(11) "php3FCA.tmp"
}


ftoup =

object(Symfony\Component\HttpFoundation\File\UploadedFile)#1066 (7) {
  ["test":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
  bool(false)
  ["originalName":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
  string(12) "CompSit.json"
  ["mimeType":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
  string(24) "application/octet-stream"
  ["size":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
  int(3259)
  ["error":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
  int(0)
  ["pathName":"SplFileInfo":private]=>
  string(49) "C:\Bitnami\wampstack-5.6.20-0\php\tmp\php3FCA.tmp"
  ["fileName":"SplFileInfo":private]=>
  string(11) "php3FCA.tmp"
}


get_object_vars (ftoup) =

array(0) {
}

ftoup[pathName] =

Answer 1

突然间，我放心，我将使用：

$ ftoup = $请求 - ＆GT;文件 - ＆GT;获得（ 'fileToUpload'） - ＆GT; getPathName（）;

类"Symfony\Component\HttpFoundation\File\UploadedFile"的其他有用功能：“getATime”，“getBasename”，“getCTime”，“getClientMimeType”，“getClientOriginalExtension”，“getClientOriginalName”，“getClientSize”，“getError”，“getErrorMessage”， “getExtension”，“getFileInfo”，“getFilename”，“getGroup”，“getInode”，“getLinkTarget”，“getMTime”，“getMaxFilesize”，“getMimeType”，“getOwner”，“getPath”，“getPathInfo”，“getPathname “，”getPerms“，”getRealPath“，”getSize“或”getType“？
