I hope I can create a Facade of AjaxResponse so that I can use it directly in Controller:

class MechanicController extends Controller {
  public function getIndex()
  {
    \AjaxResponse::success();
  }
}

Copy after login

its role is to regulate the format returned as

{
  code: "0"
  result: {
  }
}

Copy after login

Create

Creation

Service class

Create a class

<?php namespace App\Services;
class AjaxResponse {
  protected function ajaxResponse($code, $message, $data = null)
  {
    $out = [
      &#39;code&#39; => $code,
      &#39;message&#39; => $message,
    ];
    if ($data !== null) {
      $out[&#39;result&#39;] = $data;
    }
    return response()->json($out);
  }
  public function success($data = null)
  {
    $code = ResultCode::Success;
    return $this->ajaxResponse(0, &#39;&#39;, $data);
  }
  public function fail($message, $extra = [])
  {
    return $this->ajaxResponse(1, $message, $extra);
  }
}

Copy after login

in the app/Services folder

This AjaxResponse is a specific implementation class. Next we have to make a provider for this class

Create a provider

in the app/Providers folder Create class

<?php namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class AjaxResponseServiceProvider extends ServiceProvider {
  public function register()
  {
    $this->app->singleton(&#39;AjaxResponseService&#39;, function () {
      return new \App\Services\AjaxResponse();
    });
  }
}

Copy after login

Here we defined the Service name as AjaxResponseService when registering

Next we define a facade

Create facade

Create class

<?php namespace App\Facades;
use Illuminate\Support\Facades\Facade;
class AjaxResponseFacade extends Facade {
  protected static function getFacadeAccessor() { return &#39;AjaxResponseService&#39;; }
}

Copy after login

in the app/Facades folder

Modify the configuration file

Okay, now we only need to mount these two things in app.php

<?php
return [
  ...
  &#39;providers&#39; => [
    ...
    &#39;App\Providers\RouteServiceProvider&#39;,
    &#39;App\Providers\AjaxResponseServiceProvider&#39;,
  ],
  &#39;aliases&#39; => [
    ...
    &#39;Validator&#39; => &#39;Illuminate\Support\Facades\Validator&#39;,
    &#39;View&#39;   => &#39;Illuminate\Support\Facades\View&#39;,
    &#39;AjaxResponse&#39; => &#39;App\Facades\AjaxResponseFacade&#39;,
  ],
];

Copy after login
