laravel下载响应文件名未更改

Posted 2021-04-21

我正在使用laravel并尝试下载文件并更改文件名。文档告诉我可以将第二个参数用作新文件名，但是文件名不会以某种方式更改为“ testdownload.zip”。我在做什么错？

https://laravel.com/docs/5.8/responses#file-downloads

    // routes
    Route::group(['middleware' => ['web']], function()
    {
        Route::group(['namespace' => 'AppHttpControllers'], function()
        {
            Route::group(['middleware' => ['role:root|admin|store|user']], 
function()
            {
                // download purchase
                Route::get('dashboard/order/downloadfile', [
                    'as'    => 'order-download',
                    'uses'  => 'PostPostController@download'
                ]);
            });
        }
    }

    // method in Controller
    public function download(Request $request)
    {
        return response()->download(storage_path('app/lorem-ipsum-shop-1.zip'), 'testdownload.zip', ['Content-Type: application/zip']);
    }

当我做dd（response（）-> download（storage_path（'app / lorem-ipsum-shop-1.zip'），'testdownload.zip'，['Content-Type：application / zip']）时））返回以下内容（可能是权限/权限0100666吗？我在Windows上）：

答案

使用您提供的代码，我无法重现该错误。我实际上确实得到了一个testdownload.zip文件。因此，我认为您的应用程序的其他部分正在干扰。

• 您是否有任何中间件可以调整响应（或相应的响应头）？
• 您如何称呼此端点？直接从浏览器？通过AJAX吗？
• 您能否显示完整的控制器和web.php的相关部分
• 您可以使用chrome调试工具来验证响应标头吗？它们的外观应类似于下图。请注意Content-Disposition标头。

另一答案

总是清除缓存...我认为它在重命名之前会存储文件名。
