Laravel-文件上传

Laravel-文件上传

介绍

Laravel 基于 Frank de Jonge 开发的 PHP 包 Flysystem 提供了强大的文件系统抽象。Laravel 文件系统集成对使用驱动处理本地文件系统进行了简化，这些驱动包括Amazon S3，以及 Rackspace 云存储。此外在这些存储选项间切换非常简单，因为对不同系统而言，API 是一致的。

在web应用中，最常见的存储文件案例就是存储用户上传的文件，如用户头像、照片和文档等。Laravel通过使用上传文件实例上的store方法让存储上传文件变得简单。你只需要传入上传文件保存的路径并调用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 [路径可以自定义 storage_path('app/upload') 对应的是 /storage/app/upload ]
    # 如果想修改的话  public_path('/uploads') 对应的是 /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'),
    ],

],

];

实现

# 第一种方式
$fileName = $request->file('image')->store('upload');

file('image') => form表单的name值 
store('upload') => 刚刚增加的配置
$fileName => 返回的是文件名 

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

# 第二种方式
$file = $request->file('image');
# 验证是否上传成功
if ($file->isValid()) {
    # 原文件名
    $originalName = $file->getClientOriginalName();
    # 扩展名
    $ext = $file->getClientOriginalExtension();
    # Mimetype
    $type = $file->getClientMimeType();
    # 临时绝对路径
    $realPath = $file->getRealPath();

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

    # 选择磁盘
    $bool = Storage::disk('upload')->put($fileName, file_get_contents($realPath));
    dd($bool);
}
