Laravel5 How to create service provider and facade _php instance

The example in this article describes how Laravel5 creates service provider and facades. Share to everyone for your reference, specific as follows:

Laravel5 creates a façade that allows a service to be registered as a façade so that you don't need to use it in trouble. The article uses an example to illustrate how to create a service provider and a façade.

Goal

I want me to create a ajaxresponse façade that can be used directly in controller:

Class Mechaniccontroller extends Controller {public
  function GetIndex ()
  {
    \ajaxresponse::success ();
  }
}

Its function is that the canonical return format is

{
  code: ' 0 ' result
  : {
  }
}

Steps

Create service class

To create a class in the App/services folder

<?php namespace App\services;
Class Ajaxresponse {
  protected function ajaxresponse ($code, $message, $data = null)
  {
    $out = [
      ' Code ' =&G T $code,
      ' message ' => $message,
    ];
    if ($data!== null) {
      $out [' result '] = $data;
    }
    return response ()->json ($out);
  Public Function success ($data = null)
  {
    $code = resultcode::success;
    return $this->ajaxresponse (0, ', $data);
  }
  Public function fail ($message, $extra = [])
  {return
    $this->ajaxresponse (1, $message, $extra);
  }

This ajaxresponse is a concrete implementation class, and we're going to do a provider for this class

Create Provider

To create a class in the App/providers folder

<?php namespace App\providers;
Use Illuminate\support\serviceprovider;
Class Ajaxresponseserviceprovider extends ServiceProvider {public
  function register ()
  {
    $this->app- >singleton (' Ajaxresponseservice ', function () {return
      new \app\services\ajaxresponse ();}
    );
  }

Here we define the service name in the register as Ajaxresponseservice.

Now we're going to define a backyards façade.

Create a façade

To create a class in the App/facades folder

<?php namespace App\facades;
Use Illuminate\support\facades\facade;
Class Ajaxresponsefacade extends Facade {
  protected static function Getfacadeaccessor () {return ' Ajaxresponseservice '; }
}

Modify configuration file

All right, now we just need to go to the app.php and mount these two things.

<?php return
[
  ...
  ] Providers ' => [
    ...
    ] App\providers\routeserviceprovider ',
    ' App\providers\ajaxresponseserviceprovider ',
  ],
  ' aliases ' = > [
    ...
    ] Validator ' => ' illuminate\support\facades\validator ',
    ' View '   => ' Illuminate\support\facades\view ' ,
    ' ajaxresponse ' => ' App\facades\ajaxresponsefacade ',
  ],
];

Summarize

It's easier to use a façade in the Laravel5, basically and 4.
