Question

如何实现类似的解决方案：

$file = generateCSV();
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename="asd");
header("Pragma: no-cache");
header("Expires: 0");
echo $file;
exit();

使用Symfony Response对象？

现在我有

    $file = generateCSV();
    $response = new Response($file);
    $response->headers->makeDisposition(ResponseHeaderBag::DISPOSITION_ATTACHMENT, 'asd');
    $response->headers->set('Content-Disposition', 'text/csv');
    $response->headers->set('Pragma', 'no-chache');
    $response->headers->set('Expires', '0');
    return $response;

但它似乎不起作用，因为它不是发送文件下载，而是将我的文件呈现为浏览器中的文本。

任何帮助将不胜感激。

Answer 1

您没有指定内容类型。我的下载示例：

$dispositionHeader = $response->headers->makeDisposition(
            ResponseHeaderBag::DISPOSITION_ATTACHMENT,
            $filename . '.csv'
        );

$response->headers->set('Content-Type', 'text/csv; charset=utf-8');
$response->headers->set('Pragma', 'public');
$response->headers->set('Cache-Control', 'maxage=1');
$response->headers->set('Content-Disposition', $dispositionHeader);

Answer 2

我这样做了：

$response = new StreamedResponse();
    $response->setCallback(

     /* here you generate your csv file */

    );

    $response->setStatusCode(200);
    $response->headers->set('Content-Type', 'text/csv; charset=utf-8');
    $response->headers->set(
        'Content-Disposition',
        'attachment; filename="file.csv"'
    );

    return $response;
