php - 调用未定义的方法 Symfony\\Component\\HttpFoundation\\StreamedResponse::status()

Question

Laravel 版本:5.2.45PHP 版本:PHP 版本 7.0.22-0ubuntu0.16.04.1

调用未定义的方法 Symfony\Component\HttpFoundation\StreamedResponse::status()我正在尝试使用以下代码下载 csv 但出现错误

我的代码:

$headers = array(
    "Content-type"        => "text/csv",
    "Content-Disposition" => "attachment; filename=file.csv",
    "Pragma"              => "no-cache",
    "Cache-Control"       => "must-revalidate, post-check=0, pre-check=0",
    "Expires"             => "0",
);

$columns = array('userId', 'action', 'value', 'ipAddress', 'createdOn');

$callback = function () use ($data, $columns) {
    $file = fopen('php://output', 'w');

    fputcsv($file, $columns);

    foreach ($data as $item) {
        fputcsv($file, array($item['userId'], $item['action'], $item['value'], $item['ipAddress'], $item['createdOn']));
    }

    fclose($file);
};

return FacadeResponse::stream($callback, 200, $headers);

Answer 1

use Response; 在文件顶部，然后编辑此行:

return FacadeResponse::stream($callback, 200, $headers);

为此:

return Response::stream($callback, 200, $headers);
