Symfony2 创建和下载 zip 文件 [英] Symfony2 create and download zip file

问题描述

我有一个应用程序可以上传一些文件，然后我可以将其压缩为 zip 文件并下载.

I have one application that upload some files and then I can compress as zip file and download.

导出操作:

public function exportAction() {
        $files = array();
        $em = $this->getDoctrine()->getManager();
        $doc = $em->getRepository('AdminDocumentBundle:Document')->findAll();
        foreach ($_POST as $p) {
            foreach ($doc as $d) {
                if ($d->getId() == $p) {
                    array_push($files, "../web/".$d->getWebPath());
                }
            }
        }
        $zip = new \ZipArchive();
        $zipName = 'Documents-'.time().".zip";
        $zip->open($zipName,  \ZipArchive::CREATE);
        foreach ($files as $f) {
            $zip->addFromString(basename($f),  file_get_contents($f)); 
        }

        $response = new Response();
    $response->setContent(readfile("../web/".$zipName));
    $response->headers->set('Content-Type', 'application/zip');
    $response->header('Content-disposition: attachment; filename=../web/"'.$zipName.'"');
    $response->header('Content-Length: ' . filesize("../web/" . $zipName));
    $response->readfile("../web/" . $zipName);
    return $response;
    }

一切正常，直到行标题.每次我去这里时，我都会收到错误消息:警告:readfile(../web/Documents-1385648213.zip):无法打开流:没有这样的文件或目录"

everything is ok until the line header. and everytime I'm going here I got the error: "Warning: readfile(../web/Documents-1385648213.zip): failed to open stream: No such file or directory"

怎么了?

以及为什么当我上传文件时，这些文件具有 root 权限，而我创建的 zip 文件也是如此.

and why when I upload the files, this files have root permissions, and the same happens for the zip file that I create.

推荐答案

已解决:

$zip->close();
header('Content-Type', 'application/zip');
header('Content-disposition: attachment; filename="' . $zipName . '"');
header('Content-Length: ' . filesize($zipName));
readfile($zipName);

显然关闭文件很重要;)

apparently closing the file is important ;)
