在config/filesystems.php中新建本地端空间

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

在控制器中添加一个方法

public function upload(Request $request)
    {
        if ($request->isMethod('POST')){
            //var_dump($_FILES);
            $file=$request->file('file');
            //文件是否上传成功
            if ($file->isValid()){
                //原文件名
                $originalName = $file->getClientOriginalName();
                //扩展名
                $ext = $file->getClientOriginalExtension();
                //type
                $type = $file->getClientMimeType();
                //临时绝对路径
                $realPath = $file->getRealPath();

                $filename = date('Y-m-d-H-i-s').'-'.uniqid().'.'.$ext;
                $bool = Storage::disk('uploads')->put($filename,file_get_contents($realPath));
                var_dump($bool);
            }

            exit;
        }

在view中的表单

<form class="form-horizontal" method="POST" action="" enctype="multipart/form-data">
                            {{ csrf_field() }}


                            <div class="">
                                <label for="file" class="col-md-4 control-label">请选择文件</label>

                                <div class="col-md-6">
                                    <input id="file" type="file" class="form-control" name="file" >
                                </div>
                            </div>

                            <div class="form-group">
                                <div class="col-md-8 col-md-offset-4">
                                    <button type="submit" class="btn btn-primary">
                                        确定上传
                                    </button>
                                </div>
                            </div>
                        </form>

添加一条路由

Route::any('upload', 'StudentController@upload');
