英文:
Create and Download Zip File (maennchen/ZipStream-PHP)
问题
在我的项目中，我们使用了maennchen/ZipStream-PHP bundle。现在我正在尝试创建和下载zip文件，但是当我打开zip文件时，出现了"empty archive"错误。
return new StreamedResponse(function() use ($filenames, $logger) {$filename = 'example.zip';$opt = new ArchiveOptions();$opt->setContentDisposition("attachment;filename=\"$filename\"");$opt->setContentType('application/octet-stream');$opt->setEnableZip64(false);$opt->setFlushOutput(true);$opt->setSendHttpHeaders(true);$zip = new ZipStream($filename, $opt);foreach ($filenames as $f) {if (true === file_exists($f)) {try {$zip->addFileFromPath(basename($f), $f);} catch (\Exception $exception) {$logger->error($exception->getMessage());}} else {$logger->error(sprintf('File %s does not exist.', $f));}}$zip->finish();});
如果我倒出$zip，那么文件参数是空的。我认为addFile方法不起作用。
你能帮助我吗？
提前感谢。

If I dump $zip then the file argument is empty. I think the addFile method does not work.
Can you help me?
Thanks in advance.

Symfony的StreamedResponse已经发送了头部，所以你不应该在"stream"内部覆盖它们
尝试这样做：
return new StreamedResponse(function() use ($filenames, $logger) {$opt = new \ZipStream\Option\Archive();$opt->setZeroHeader(true);$opt->setEnableZip64(false);$zip = new ZipStream(null, $opt);foreach ($filenames as $f) {if (true === file_exists($f)) {try {$zip->addFileFromPath(basename($f), $f);} catch (\Exception $exception) {$logger->error($exception->getMessage());}} else {$logger->error(sprintf('File %s does not exist.', $f));}}$zip->finish();},200,['Content-Disposition' => 'attachment;filename="example.zip"','Content-Type' => 'application/octet-stream',]);
英文:
Symfony's StreamedResponse is sending the headers already, so you should not override them inside the "stream"
Try this;
return new StreamedResponse(function() use ($filenames, $logger) {$opt = new \ZipStream\Option\Archive();$opt->setZeroHeader(true);$opt->setEnableZip64(false);$zip = new ZipStream(null, $opt);foreach ($filenames as $f) {if (true === file_exists($f)) {try {$zip->addFileFromPath(basename($f), $f);} catch (\Exception $exception) {$logger->error($exception->getMessage());}} else {$logger->error(sprintf('File %s does not exist.', $f));}}$zip->finish();},200,['Content-Disposition' => 'attachment;filename="example.zip"','Content-Type' => 'application/octet-stream',]);
