超薄的PHP框架控制器目录

Question

I'm using Slim Framework for a new app and I want a controller directory in my src folder. I keep getting the error message:

Callable \App\Controllers\MobileApiController does not exist

dependencies.php

$container['MobileApiController'] = function ($c)
{
    return new \App\Controllers\MobileApiController;
};

routes.php

$app->get('/user', '\App\Controllers\MobileApiController:getUser');    

MobileApiController.php

<?php

namespace App\Controllers;

use Psr\Http\Message\ServerRequestInterface as Request;
use Psr\Http\Message\ResponseInterface as Response;

class MobileApiController
{

    protected $container;
    public function __construct($c) {
        $this->container = $c;
    }

    public function getUser($request, $response, $args)
    {
       var_dump($request);
    }
}

composer.json

"autoload-dev": {
    "psr-4": {
        "App\\": "src/",
        "Tests\\": "tests/"
    }
},

The 'src' folder has a 'Controllers' folder and 'routes.php' and 'dependencies.php' files

Answer 1

Usually the namespace Test (singular) or App\Test is dev-related only and App is prod and dev-related. The App\Test namespace belongs to autoload-dev and App belongs to autoload.

Example (composer.json):

 "autoload": {
    "psr-4": {
      "App\\": "src/"
    },
  },
  "autoload-dev": {
    "psr-4": {
      "App\\Test\\": "tests/"
    }
  },
