Question

我有一个Invoice控制器，它看起来像这样

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Input;
use App\Event;
use App\Employee;
use App\Invoice;
use Mail;
use View;

class ViewinvoiceController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function getIndex($order_id)
    {
       $id=$order_id;

        $invoicedata=Invoice::where('Id',$id)->get();


    $html22 =  View('viewinvoice')->with(array('invoicedata'=>$invoicedata ))->render();

     require_once(app_path().'/libs/html2pdf/html2pdf.class.php');


      $html2pdf = new \HTML2PDF('P','A4','en',true,'UTF-8',array(0, 0, 0, 0));

      // $html2pdf->pdf->SetDisplayMode('fullpage');

      $html2pdf->WriteHTML($html22);

     $html2pdf->Output('Invoice.pdf');


    }

}

我想在其他控制器中使用此控制器，如下所示

class CollectionController extends Controller
    {

        public function __construct(){

    $this->middleware('role:collector'); // replace 'collector' with whatever role you need.
      }
       public function getInvoice($order_id){
       //Here I have to write the logic of getting the invoice from the invoiceController 
}

}

我用Google搜索并发现一种方法是编写服务以获取发票，

我可以把它作为一个普通的班级作为服务，但我不知道什么是正确的方式在laravel 5

任何建议

Answer 1

在另一个Controller中使用Controller而不是设计标准，如果您认为某些功能需要在多个控制器或位置中触发，那么Jobs就会出现。

了解有关Laravel Jobs here的更多信息。作业可以同步或异步运行，这取决于您的应用程序。

Answer 2

您可以将此特征置于App\Services内并保存名称为ViewinvoiceTrait.php的文件

<?php
namespace App\Services;

use App\Invoice;
use View;

trait ViewinvoiceTrait {

    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function getIndex($order_id) {
        $id = $order_id;

        $invoicedata = Invoice::where('Id', $id)->get();


        $html22 = View('viewinvoice')->with(array('invoicedata' => $invoicedata))->render();

        require_once(app_path() . '/libs/html2pdf/html2pdf.class.php');


        $html2pdf = new \HTML2PDF('P', 'A4', 'en', true, 'UTF-8', array(0, 0, 0, 0));

        // $html2pdf->pdf->SetDisplayMode('fullpage');

        $html2pdf->WriteHTML($html22);

        return $html2pdf->Output('Invoice.pdf');
    }

}

并在你的控制器中使用它，如

use App\Services\ViewinvoiceTrait;

class CollectionController extends Controller
    {

     use ViewinvoiceTrait;

     public function __construct(){
        $this->middleware('role:collector'); // replace 'collector' with whatever role you need.
     }

     public function getInvoice($order_id){
          $data = $this->getIndex($order_id);
     }

}
