laravel 文件上传

文件上传

Laravel的文件系统是基于Frankde Jonge的Flysystem扩展包

提供了简单的接口，可以操作本地端空间，Amazons3,Rackspace Cloud Storage

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

 

配置文件

1.Config/filesystems.php

    'disks' => [

        'local' => [

            'driver' => 'local',

            'root' => storage_path('app'),

        ],

        'public' => [

            'driver' => 'local',

            'root' =>storage_path('app/public'),

            'visibility' => 'public',

        ],

                     //新建立一个uploads

        'uploads' =>[

            'driver' => 'local',

            //storage_path对应的是目录下storage

            'root' =>storage_path('app/uploads'),

            'visibility' => 'public',

        ],

        's3' => [

            'driver' => 's3',

            'key' => 'your-key',

            'secret' => 'your-secret',

            'region' => 'your-region',

3.controllers

public function upload(Request $request){    if($request->isMethod('POST')) {        //print_r($_FILES);        //source表单名       $file = $request->file('source');       //文件是否上传成功       if($file->isValid()) {           //取原文件名           $originalName = $file->getClientOriginalName();           //取扩展名           $ext = $file->getClientOriginalExtension();           //取文件类型           $type = $file->getClientMimeType();           //临时文件的绝对路径           $realPath = $file->getRealPath();           //定义文件名           $fileName = date("YmdHis"). '-' . uniqid(). '.' . $ext;           //uploads为config/filesystems里自定义           $bool = Storage::disk('uploads')->put($fileName, file_get_contents($realPath));           print_r($bool);exit;       }    }    return view('student.upload');}
