How to Create a REST API for Yii2-basic-template

Question

I wanted to create a REST API for a yii2 basic template. I followed the following link.

I created a table named users, a controller named UserController

<?php
namespace app\controllers;

use yii\rest\ActiveController;

class UserController extends ActiveController
{
    public $modelClass = 'app\models\User';
}
?>

and in the web

   'urlManager' => [
    'enablePrettyUrl' => true,
    'enableStrictParsing' => true,
    'showScriptName' => false,
    'rules' => [
        ['class' => 'yii\rest\UrlRule', 'controller' => 'user'],
    ],
],

        'request' => [
            // !!! insert a secret key in the following (if it is empty) - this is required by cookie validation
            'cookieValidationKey' => '4534',
            'parsers' => [
        'application/json' => 'yii\web\JsonParser',
    ],
        ],  

my file name is restapi so i tried this url http://localhost/~user/restapi/web/ all i get is a 404 page not found error. Any help would be appreciated

Rest Api is very simple to to implement in Yii2 basic app. Just follow the steps below. This code is working for me.

application structure

yourapp
+ web
+ config
+ controllers
...
+ api
  + config
  + modules
    + v1
      + controllers
  .htaccess
  index.php

api/index.php

<?php

// comment out the following two lines when deployed to production
defined('YII_DEBUG') or define('YII_DEBUG', true);
defined('YII_ENV') or define('YII_ENV', 'dev');

require(__DIR__ . '/../vendor/autoload.php');
require(__DIR__ . '/../vendor/yiisoft/yii2/Yii.php');

// Use a distinct configuration for the API
$config = require(__DIR__ . '/config/api.php');

(new yii\web\Application($config))->run();

api/.htaccess

Options +FollowSymLinks
IndexIgnore */*

RewriteEngine on

# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

# otherwise forward it to index.php
RewriteRule . index.php

api/config/api.php

<?php

$db     = require(__DIR__ . '/../../config/db.php');
$params = require(__DIR__ . '/params.php');

$config = [
    'id' => 'basic',
    'name' => 'TimeTracker',
    // Need to get one level up:
    'basePath' => dirname(__DIR__).'/..',
    'bootstrap' => ['log'],
    'components' => [
        'request' => [
            // Enable JSON Input:
            'parsers' => [
                'application/json' => 'yii\web\JsonParser',
            ]
        ],
        'log' => [
            'traceLevel' => YII_DEBUG ? 3 : 0,
            'targets' => [
                [
                    'class' => 'yii\log\FileTarget',
                    'levels' => ['error', 'warning'],
                     // Create API log in the standard log dir
                     // But in file 'api.log':
                    'logFile' => '@app/runtime/logs/api.log',
                ],
            ],
        ],
        'urlManager' => [
            'enablePrettyUrl' => true,
            'enableStrictParsing' => true,
            'showScriptName' => false,
            'rules' => [
                ['class' => 'yii\rest\UrlRule', 'controller' => ['v1/project','v1/time']],
            ],
        ], 
        'db' => $db,
    ],
    'modules' => [
        'v1' => [
            'class' => 'app\api\modules\v1\Module',
        ],
    ],
    'params' => $params,
];

return $config;

api/modules/v1/Module.php

<?php
// Check this namespace:
namespace app\api\modules\v1;

class Module extends \yii\base\Module
{
    public function init()
    {
        parent::init();

        // ...  other initialization code ...
    }
}

api/modules/v1/controllers/ProjectController.php

<?php
namespace app\api\modules\v1\controllers;

use yii\rest\ActiveController;

class ProjectController extends ActiveController
{
    // We are using the regular web app modules:
    public $modelClass = 'app\models\Project';
}
