一、简介

Laravel 有很棒的文件系统抽象层,是基于 Frank de Jonge 的 Flysystem 扩展包。 Laravel 集成的 Flysystem 提供了简单的接口,可以操作本地端空间、 Amazon S3 、 Rackspace Cloud Storage 。更方便的是,它可以非常简单的切换不同保存方式,但仍使用相同的 API 操作!

默认使用本地端空间。当然,你也可以设置多组磁盘,甚至在多个磁盘使用相同的驱动。Laravel文件系统提供了非常强大的功能,但是本文只介绍常用的文件上传功能。

本文通过介绍使用本地端空间来介绍Laravel中文件上传的使用。

二、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‘,
        ],

    ],

];

三、代码实现文件上传

1. 控制器代码

技术分享图片
<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use Illuminate\Support\Facades\Storage;


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)
                //这里的uploads是配置文件的名称
                $bool = Storage::disk(‘uploads‘)->put($filename, file_get_contents($realPath));
                var_dump($bool);

            }

        }

        return view(‘upload‘);
    }
}

 2-1.upload.blade.php 模板代码(上传组件为bootstrap-fileinput)如果太乱,可以看下面的最简单的页面:

2-2. 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>
