Downloading a file in Laravel
提问by Jesse Orange
In Laravel, I have a page in which I am trying to provide download links to files and I am using Laravel Filemananager to upload these files.
在 Laravel 中，我有一个页面，我试图在其中提供文件的下载链接，并且我正在使用 Laravel Filemananager 上传这些文件。
The path to these files is set in the lfm.phpconfig file as:
这些文件的路径在lfm.php配置文件中设置为：
/*
|--------------------------------------------------------------------------
| Working Directory
|--------------------------------------------------------------------------
*/
// Which folder to store files in project, fill in 'public', 'resources', 'storage' and so on.
// You should create routes to serve images if it is not set to public.
'base_directory' => 'public',
'images_folder_name' => 'assets/uploads/images',
'files_folder_name' => 'storage/files',
'shared_folder_name' => 'shares',
'thumb_folder_name' => 'thumbs',
I followed the documentation on the Laravel website regarding the publicand storagefolders which says the following:
我遵循了 Laravel 网站上关于public和storage文件夹的文档，其中说明如下：
The public disk is intended for files that are going to be publicly accessible. By default, the public disk uses the local driver and stores these files in storage/app/public. To make them accessible from the web, you should create a symbolic linkfrom public/storageto storage/app/public.
This convention will keep your publicly accessible files in one directory that can be easily shared across deployments when using zero down-time deployment systems like Envoyer.
To create the symbolic link, you may use the storage:link Artisan command:
php artisan storage:link
公共磁盘用于将要公开访问的文件。默认情况下，公共磁盘使用本地驱动程序并将这些文件存储在 storage/app/public 中。为了使它们可以从网络访问，您应该创建一个从public/storage到 storage/app/public的符号链接。
该约定将您的可公开访问的文件保存在一个目录中，当使用 Envoyer 等零停机时间部署系统时，该目录可以轻松地在部署之间共享。
要创建符号链接，您可以使用 storage:link Artisan 命令：
php工匠存储：链接
Before anything else I also set the following:
在此之前，我还设置了以下内容：
- In my
.envI changed the app URL to:http://127.0.0.1:8000which is wherephp artisan serverspins up a local server. In
filesystems.phpI changed the public array to the following:'public' => [ 'driver' => 'local', 'root' => storage_path('app/public'), 'url' => env('APP_URL').'/storage', 'visibility' => 'public', ],
- 在我
.env的应用程序 URL 中，我将应用程序 URL 更改为：http://127.0.0.1:8000这是php artisan server启动本地服务器的地方。 在
filesystems.php我将公共数组更改为以下内容：'public' => [ 'driver' => 'local', 'root' => storage_path('app/public'), 'url' => env('APP_URL').'/storage', 'visibility' => 'public', ],
I then created the SymLink.
然后我创建了 SymLink。
In my public directory I then had the below:
在我的公共目录中，我有以下内容：
Which is a link to storage/app/public
这是一个链接 storage/app/public
Then I uploaded a file to shares, so in my storagefolder I now had:
然后我上传了一个文件到shares，所以在我的storage文件夹中我现在有：
app/public/shares/name-of-file
app/public/shares/name-of-file
To test this I have the following Controller and View:
为了测试这个，我有以下控制器和视图：
Controller:
控制器：
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;
class TemplateController extends Controller
{
public function index()
{
$files = Storage::allFiles('files/shares');
return view('pages.templates-and-tools.index', compact('files'));
}
}
Relevant part in view
相关部分查看
<table id="templates" class=" table-striped table-vaccancies table-responsive">
<thead>
<tr>
<th class="col-md-1 col-xs-1">Type</th>
<th class="col-md-6 col-xs-6">Name</th>
<th class="col-md-2 col-xs-2">Category</th>
<th class="col-md-2 col-xs-2">Modified</th>
<th class="col-md-1 col-xs-1">Size</th>
</tr>
<tr class="warning no-result">
<td colspan="5">
<i class="fa fa-warning"></i>
<h3 class="text-center"> No result</h3>
</td>
</tr>
</thead>
<tbody>
@foreach ($files as $file)
@php
$date = Storage::lastModified($file); $date = gmdate("d/m/Y - H:i", $date);
$size = Storage::size($file); $size = ceil ($size/1000);
$url = Storage::url($file);
$fileName = pathinfo($file)['filename'];
$Category = pathinfo($file)['dirname'];
$type = pathinfo($file)['extension'];
$Category = basename(dirname( $file))
@endphp
<tr>
<td>{{$type}}</td>
<td>
<a href="{{ Storage::download($url) }} ">{{$fileName }}</a>
</td>
<td>{{$Category}}</td>
<td> {{$date}}</td>
<td>{{$size}}kb</td>
</tr>
@endforeach
</tbody>
</table>
The above grabs everything in the Storage folder under files/shares, I then just spit out a bunch of information about the file into each table cell.
以上抓取了 Storage 文件夹中的所有内容files/shares，然后我将有关文件的一堆信息吐出到每个表格单元格中。
The issue I'm facing is with this line:
我面临的问题是这一行：
<a href="{{ Storage::download($url) }}">{{$fileName }}</a>
<a href="{{ Storage::download($url) }}">{{$fileName }}</a>
It returns the following error:
它返回以下错误：
File not found at path: http:/127.0.0.1:8000/storage/files/shares/Hummingbird_Technologies_ES.pdf (View: C:\xampp\htdocs\my-newable\resources\views\pages\templates-and-tools\index.blade.php)
File not found at path: http:/127.0.0.1:8000/storage/files/shares/Hummingbird_Technologies_ES.pdf (View: C:\xampp\htdocs\my-newable\resources\views\pages\templates-and-tools\index.blade.php)
Which is a pretty straightforward error, but...
这是一个非常简单的错误，但是......
You can see that the file exists.
可以看到文件存在。
So, what am I doing wrong?
那么，我做错了什么？

First of all, check your file is uploaded successfully.
首先，检查您的文件是否上传成功。
And then specific url added in atag downloadparameter. Like this.
然后在a标签download参数中添加特定的 url 。像这样。
<a href="{{ Storage::url($path) }}" download>{{$fileName }}</a>
<a href="{{ Storage::url($path) }}" download>{{$fileName }}</a>
Or added download url in your atag. Like this.
或在您的a标签中添加下载 url 。像这样。
<a href="{{ route('download_url',$path) }}">Download</a>
<a href="{{ route('download_url',$path) }}">Download</a>
Controller.
控制器。
public function download($path)
{
return Storage::download($path);
}
