laravel 文件上傳

文件上傳 案例

---

1、配置
配置文件在 config/filesystems.php 

<?php

return [

    /*
    |--------------------------------------------------------------------------
    | Default Filesystem Disk
    |--------------------------------------------------------------------------
    |
    | Here you may specify the default filesystem disk that should be used
    | by the framework. The "local" disk, as well as a variety of cloud
    | based disks are available to your application. Just store away!
    |
    */

    'default' => env('FILESYSTEM_DRIVER', '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.
    |
    */

    'cloud' => env('FILESYSTEM_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.
    |
    | Supported Drivers: "local", "ftp", "sftp", "s3", "rackspace"
    |
    */

    'disks' => [

        'local' => [
            'driver' => 'local',
            'root' => storage_path('app'),
        ],
        'public' => [
            'driver' => 'local',
            'root' => storage_path('app/public/img'),//文件真實位置
            'url' => env('APP_URL').'/storage',
            'visibility' => 'public',
        ],

        's3' => [
            'driver' => 's3',
            'key' => env('AWS_ACCESS_KEY_ID'),
            'secret' => env('AWS_SECRET_ACCESS_KEY'),
            'region' => env('AWS_DEFAULT_REGION'),
            'bucket' => env('AWS_BUCKET'),
            'url' => env('AWS_URL'),
        ],

    ],

];

2、代碼實現

控制器：

public function Upload(Request $request){//文件上傳
$file= $request->file('file');//獲取文件
if ($file->isValid()){
            $ext = $file->getClientOriginalExtension();//獲取文件的後綴名
            $path = $file->getRealPath();//獲取文件的 絕對路徑
            $filename = date('Y-m-d-h-i-s').'.'.$ext;//定義一個文件名
            Storage::disk('public')->put($filename,file_get_contents($path));//移動文件
　　}
}

---

視圖層：

<div>
    <img class="img" src="{{asset('storage/img/文件名')}}">{{--這裏路徑和配置文件裏對應--}}
</div

文件的上傳表單：

<form method="post" enctype="multipart/form-data" >    
    <input type="file" name="file">
    <button type="submit"> 提交 </button>
</form>

　　

這裏用到了軟鏈接須要在命令行輸入：artisan storage:link
