aravel 5.2框架功能强大了我们可以用它来做许多的事情了,下面我们来看一篇关于Laravel 5.2文件上传的功能使用示例,希望文章能够帮助到各位朋友。
配置
文件系统的配置文件在 config/filesystems.php 文件中,此处我们新建一个uploads本地磁盘空间用于存储上传的文件,具体配置项及说明如下:
<?php
return [
/*
|--------------------------------------------------------------------------
| Default Filesystem Disk
|--------------------------------------------------------------------------
|
| Here you may specify the default filesystem disk that should be used
| by the framework. A "local" driver, as well as a variety of cloud
| based drivers are available for your choosing. Just store away!
|
| Supported: "local", "ftp", "s3", "rackspace"
|
*/
// 默认使用本地端空间 支持 "local", "ftp", "s3", "rackspace"
'default' => 'local',
/*
|--------------------------------------------------------------------------
| Default Cloud Filesystem Disk
|--------------------------------------------------------------------------
|
| Many applications store files both locally and in the cloud. For this
| reason, you may specify a default "cloud" driver here. This driver
| will be bound as the Cloud disk implementation in the container.
|
*/
// 云存储使用 Amazon S3
'cloud' => 's3',
/*
|--------------------------------------------------------------------------
| Filesystem Disks
|--------------------------------------------------------------------------
|
| Here you may configure as many filesystem "disks" as you wish, and you
| may even configure multiple disks of the same driver. Defaults have
| been setup for each driver as an example of the required options.
|
*/
'disks' => [
// 本地端的local空间
'local' => [
'driver' => 'local',
'root' => storage_path('app'),
],
// 本地端的public空间
'public' => [
'driver' => 'local',
'root' => storage_path('app/public'),
'visibility' => 'public',
],
// 新建一个本地端uploads空间(目录) 用于存储上传的文件
'uploads' => [
'driver' => 'local',
// 文件将上传到storage/app/uploads目录
'root' => storage_path('app/uploads'),
// 文件将上传到public/uploads目录 如果需要浏览器直接访问 请设置成这个
//'root' => public_path('uploads'),
],
// Amazon S3 相关配置
's3' => [
'driver' => 's3',
'key' => 'your-key',
'secret' => 'your-secret',
'region' => 'your-region',
'bucket' => 'your-bucket',
],
],
];
我的配置是这样的 // 新建一个本地端uploads空间(目录) 用于存储上传的文件 'uploadsFile' => [ 'driver' => 'local', // 文件将上传到storage/app/uploads目录 // 'root' => storage_path('app/uploads'), // 文件将上传到public/uploads目录 如果需要浏览器直接访问 请设置成这个 'root' => public_path('storage'), 'url' => env('APP_URL').'/storage' ],
'uploads_public' => [ 'driver' => 'local', // 文件将上传到storage/app/uploads目录 // 'root' => storage_path('app/uploads'), // 文件将上传到public/uploads目录 如果需要浏览器直接访问 请设置成这个 'root' => public_path('storage').'/../', 'url' => env('APP_URL') ],
在.env中增加如下配置
三、代码实现文件上传
1. 控制器代码
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Storage;
use App\Http\Requests;
class FileController extends Controller
{
// 文件上传方法
public function upload(Request $request)
{
if ($request->isMethod('post')) {
$file = $request->file('picture');
// 文件是否上传成功
if ($file->isValid()) {
// 获取文件相关信息
$originalName = $file->getClientOriginalName(); // 文件原名
$ext = $file->getClientOriginalExtension(); // 扩展名
$realPath = $file->getRealPath(); //临时文件的绝对路径
$type = $file->getClientMimeType(); // image/jpeg
// 上传文件
$filename = date('Y-m-d-H-i-s') . '-' . uniqid() . '.' . $ext;
// 使用我们新建的uploads本地存储空间(目录)
$bool = Storage::disk('uploads')->put($filename, file_get_contents($realPath));
var_dump($bool);
}
}
return view('upload');
}
}
2. 最基础的 upload.blade.php 模板代码:
<form method="post" enctype="multipart/form-data" >
<input type="file" name="picture">
<button type="submit"> 提交 </button>
</form>
获取到文件后,即可对文件进行各种处理。如果是图片,可以进行各种缩放及裁剪操作。
