Laravel8导出excel返回值的简单想法

最近在使用 MaatwebsiteExcel 扩展进行 excel 的导出功能,具体怎么操作,这里不详细说了,通过下面代码导出:

//导出excel【$head是excel表头,$list是数据】 return Excel::download(new CustomerExport($head, $list), date('YmdHis') . '.xls');

我本着好奇打印这个返回值:

print_r(Excel::download(new CustomerExport($head, $list), date('YmdHis') . '.xls'));

结果如下:

SymfonyComponentHttpFoundationBinaryFileResponse Object (     [file:protected] => SymfonyComponentHttpFoundationFileFile Object         (             [pathName:SplFileInfo:private] => /home/vagrant/www/admin/storage/framework/cache/laravel-excel/laravel-excel-4U89uL9YLn4vNb1QrCDelsmv4Yrk3Ff.xls             [fileName:SplFileInfo:private] => laravel-excel-4U89uL9YLn4vNb1QrCDelsmv4Yrk3Ff.xls         )     [offset:protected] => 0     [maxlen:protected] => -1     [deleteFileAfterSend:protected] => 1     [headers] => SymfonyComponentHttpFoundationResponseHeaderBag Object         (             [computedCacheControl:protected] => Array                 (                     [public] => 1                 )             [cookies:protected] => Array                 (                 )             [headerNames:protected] => Array                 (                     [cache-control] => Cache-Control                     [date] => Date                     [last-modified] => Last-Modified                     [content-disposition] => Content-Disposition                 )             [headers:protected] => Array                 (                     [cache-control] => Array                         (                             [0] => public                         )                     [date] => Array                         (                             [0] => Thu, 08 Dec 2022 05:57:26 GMT                         )                     [last-modified] => Array                         (                             [0] => Thu, 08 Dec 2022 07:16:21 GMT                         )                     [content-disposition] => Array                         (                             [0] => attachment; filename=20221208152026.xls                         )                 )             [cacheControl:protected] => Array                 (                     [public] => 1                 )         )     [content:protected] =>      [version:protected] => 1.0     [statusCode:protected] => 200     [statusText:protected] => OK     [charset:protected] =>  )

很明显他是个对象

因为我是前后端分离的,接口也是直接上面代码的,前端同学使用 a 标签跳到接口地址进行下载的,可以成功。但是打开 F12 的 network 查看返回值,前端拿到的是文件流,如下:

为什么直接运行接口返回的是个对象,前端拿到居然变为文件流了?

原来是返回的时候,自动给返回头加了两个参数

Content-Disposition:attachment; filename=20221208152026.xls Content-Type:application/vnd.ms-excel

Content-Disposition 不就是对象里面的头消息嘛
