页面和command命令行双导入的实现

需求描述：

excel的导入逻辑在web页面和command均可以，command可以显示导入进度条功能。

实现思路：

1. 创建excel导入类的实现ImportVersionAtomextra，实现接口ToModel, WithHeadingRow, WithBatchInserts，不实现接口WithProgressBar；
2. 创建excel导入类的command实现ImportVersionAtomextraCmd，继承ImportVersionAtomextra并同时实现WithProgressBar接口；
3. 在command逻辑调用ImportVersionAtomextraCmd的实例；
4. 在文件上传逻辑调用ImportVersionAtomextra的实例。

关键代码

1. excel导入类的实现

   class ImportVersionAtomextra implements ToModel, WithHeadingRow, WithBatchInserts
   {
    public function model(array $row)
    {
        //逻辑实现略
    }
    public function batchSize(): int
    {
        return 100;
    }
   }    

2. excel导入类的command实现

   class ImportVersionAtomextraCmd extends ImportVersionAtomextra implements WithProgressBar
   {
    use Importable;
   }

3. command逻辑调用

   class importVersionAtomExtraExcel extends Command
   {
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'import:versionatomextra {versionid : The ID of the version for product} {filepath : the file path}';
   
    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'import version atom\'s extra information from excel';
   
    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }
   
    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        $this->output->title('Starting import');
        $this->info('1. Starting sendfile.');
        Storage::delete('allparalist.xlsx');
        Storage::putFileAs('', new File($this->argument('filepath')), 'allparalist.xlsx');
        $this->output->text('Import successful');
   
        $this->info('2. Starting import version atom extra info.');
        $VerionAtomextra = new ImportVersionAtomextraCmd;
        $VerionAtomextra->versionid = $this->argument('versionid');
        $VerionAtomextra->withOutput($this->output)->import('storage\app\allparalist.xlsx');
        Storage::delete('allparalist.xlsx');
        $this->output->success('Import successful');
    }
   }

4. 文件上传逻辑调用

   // $model ...
        try{
            // $request ...
            $file = $request->file('file'); 
            $ImportVersionAtomextra = new ImportVersionAtomextra;            
            Excel::import($ImportVersionAtomextra,$file);            
   
            return $this->response()->success('Import success...')->refresh();
        }
        catch (\Exception $e){
            return $this->response()->error($e->getMessage());
        }

   // $model ...
        try{
            // $request ...
            $file = $request->file('file'); 
            $ImportVersionAtomextra = new ImportVersionAtomextra;            
            Excel::import($ImportVersionAtomextra,$file);            
   
            return $this->response()->success('Import success...')->refresh();
        }
        catch (\Exception $e){
            return $this->response()->error($e->getMessage());
        }
