Laravel-文件上傳

標簽（空格分隔）： php

---

介紹

Laravel 基於 Frank de Jonge 開發的 PHP 包 Flysystem 提供了強大的文件系統抽象。Laravel 文件系統集成對使用驅動處理本地文件系統進行了簡化，這些驅動包括Amazon S3，以及 Rackspace 雲存儲。此外在這些存儲選項間切換非常簡單，因為對不同系統而言，API 是一致的。

在web應用中，最常見的存儲文件案例就是存儲用戶上傳的文件，如用戶頭像、照片和文檔等。Laravel通過使用上傳文件實例上的store方法讓存儲上傳文件變得簡單。你只需要傳入上傳文件保存的路徑並調用store方法即可

配置

修改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", "s3", "rackspace"
|
*/

'disks' => [

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

    'public' => [
        'driver' => 'local',
        'root' => storage_path('app/public'),
        'url' => env('APP_URL').'/storage',
        'visibility' => 'public',
    ],
    
    |-----------------------------------------------------------------------------------|
    # 增加配置 [路徑可以自定義 storage_path('app/upload') 對應的是 /storage/app/upload ]
    # 如果想修改的話  public_path('/uploads') 對應的是 /public下的uploads
    
    'upload' => [
        'driver' => 'local',
        'root' => storage_path('app/upload'),
    ],
    
    |-----------------------------------------------------------------------------------|

    's3' => [
        'driver' => 's3',
        'key' => env('AWS_KEY'),
        'secret' => env('AWS_SECRET'),
        'region' => env('AWS_REGION'),
        'bucket' => env('AWS_BUCKET'),
    ],

],

];

實現

# 第一種方式
$fileName = $request->file('image')->store('upload');

file('image') => form表單的name值 
store('upload') => 剛剛增加的配置
$fileName => 返回的是文件名 

-----------------------------------------------------------------------------------

# 第二種方式
$file = $request->file('image');
# 驗證是否上傳成功
if ($file->isValid()) {
    # 原文件名
    $originalName = $file->getClientOriginalName();
    # 擴展名
    $ext = $file->getClientOriginalExtension();
    # Mimetype
    $type = $file->getClientMimeType();
    # 臨時絕對路徑
    $realPath = $file->getRealPath();

    # 自定義文件名
    $fileName = date('Ymd').'/'.uniqid().'.'.$ext;

    # 選擇磁盤
    $bool = Storage::disk('upload')->put($fileName, file_get_contents($realPath));
    dd($bool);
