Laravel:如何访问本地磁盘中的文件?- 文件不存在 [英] Laravel: how to access a file in the local disk? - File does not exist

问题描述

在laravel中上传后，我正在尝试编辑一个excel文件.该文件已上传到本地磁盘，因此没有人可以从公众访问它.

I'm trying to edit an excel file after uploading it in laravel. the file is uploaded to local disk, so no one can access it from the public.

Filesystems.php

'local' => [
        'driver' => 'local',
        'root' => storage_path('app')

Routes.php

Route::get('test',function()
{

    // Create new PHPExcel object
    $objPHPExcel = new PHPExcel();
    $objPHPExcel = PHPExcel_IOFactory::load(Storage::disk('local')->url('margin/analyser/0IGkQQgmGXkHrV9ISnBTrGyZFUPfjz3cWJbLGbDN.xlsx'));
    $objPHPExcel->setActiveSheetIndex(0);
    echo $objPHPExcel->getActiveSheet()->getHighestRow();
})->middleware('admin');

我不断收到错误消息:

Could not open /storage/margin/analyser/0IGkQQgmGXkHrV9ISnBTrGyZFUPfjz3cWJbLGbDN.xlsx for reading! File does not exist.

这有效

     $objPHPExcel = PHPExcel_IOFactory::load('..'.Storage::disk('local')->url('app/margin/analyser/0IGkQQgmGXkHrV9ISnBTrGyZFUPfjz3cWJbLGbDN.xlsx'));

但是很烦人.我以为在filesystems.php中指定'root'=> storage_path('app')意味着Storage :: disk('local')将直接在应用程序中

but it is annoying. I thought specifying 'root' => storage_path('app') in the filesystems.php means that Storage::disk('local') will be in the app directly

推荐答案

URL方法用于获取文件的URL(即从浏览器访问文件的内容).您要使用 get()方法的ID.

The URL method is used to get URL for the file (ie: something to access it from the browser). What you want to use id the get() method.

$contents = Storage::get(''margin/analyser/0IGkQQgmGXkHrV9ISnBTrGyZFUPfjz3cWJbLGbDN.xlsx'');

话虽这么说，使用Laravel操纵上传的文件还有更简便的方法.

That being said, there is still easier way to manipulate uploaded files with Laravel.

// this will take the uploaded file from the request
// and store it into `/storage/someFolder`
$path = $request->file('file')->store('someFolder');

然后您可以使用返回到 $ path 的值来访问文件.

You can then use the value returned to $path to access the file.

编辑

经过下面的讨论，OP决定，即使这不是完美的解决方案，他也会使用 $ objPHPExcel = PHPExcel_IOFactory :: load('..'.Storage :: disk('local')-> url($ fileLocation)); .

After discussion below, it was decided by OP that, even if it's not the the perfect solution, he would use $objPHPExcel = PHPExcel_IOFactory::load('..'.Storage::disk('local')->url($fileLocation));.
