How does the Yii framework access the controller under the custom module?

Question:

How to access the actions in the Site controller? As shown in the picture:

Solution:

1. Create the directory

First create the directory structure as above, and the directory under the api There are three folders and one file Module.php. The content of this php file is as follows:

<?php

namespace app\modules\api;

/**
 * api module definition class
 */
class Module extends \yii\base\Module
{
    /**
     * @inheritdoc
     */
    public $controllerNamespace = &#39;app\modules\api\controllers&#39;;

    /**
     * @inheritdoc
     */
    public function init()
    {
        parent::init();

        // custom initialization code goes here
    }
}

2. web.php

Remember that there is a web.php file in the config folder in the root directory of the project? Add the following fields:

<?php

$params = require __DIR__ . &#39;/params.php&#39;;
$db = require __DIR__ . &#39;/db.php&#39;;

$config = [
    &#39;id&#39; => &#39;basic&#39;,
    &#39;basePath&#39; => dirname(__DIR__),
    &#39;bootstrap&#39; => [&#39;log&#39;],
    &#39;aliases&#39; => [
        &#39;@bower&#39; => &#39;@vendor/bower-asset&#39;,
        &#39;@npm&#39;   => &#39;@vendor/npm-asset&#39;,
    ],
    &#39;components&#39; => [
        &#39;request&#39; => [
            // !!! insert a secret key in the following (if it is empty) - this is required by cookie validation
            &#39;cookieValidationKey&#39; => &#39;jjsYJ_ju0W8ifOv5mY3JBMI6DOppFlo6&#39;,
        ],
        &#39;cache&#39; => [
            &#39;class&#39; => &#39;yii\caching\FileCache&#39;,
        ],
        &#39;user&#39; => [
            &#39;identityClass&#39; => &#39;app\models\User&#39;,
            &#39;enableAutoLogin&#39; => true,
        ],
        &#39;errorHandler&#39; => [
            &#39;errorAction&#39; => &#39;site/error&#39;,
        ],
        &#39;mailer&#39; => [
            &#39;class&#39; => &#39;yii\swiftmailer\Mailer&#39;,
            // send all mails to a file by default. You have to set
            // &#39;useFileTransport&#39; to false and configure a transport
            // for the mailer to send real emails.
            &#39;useFileTransport&#39; => true,
        ],
        &#39;log&#39; => [
            &#39;traceLevel&#39; => YII_DEBUG ? 3 : 0,
            &#39;targets&#39; => [
                [
                    &#39;class&#39; => &#39;yii\log\FileTarget&#39;,
                    &#39;levels&#39; => [&#39;error&#39;, &#39;warning&#39;],
                ],
            ],
        ],
        &#39;db&#39; => $db,
        /*
        &#39;urlManager&#39; => [
            &#39;enablePrettyUrl&#39; => true,
            &#39;showScriptName&#39; => false,
            &#39;rules&#39; => [
            ],
        ],
        */
    ],
    &#39;modules&#39; => [
        &#39;api&#39; => [
            &#39;class&#39; => &#39;app\modules\api\Module&#39;,
        ],
    ],
    &#39;params&#39; => $params,
];

if (YII_ENV_DEV) {
    // configuration adjustments for &#39;dev&#39; environment
    $config[&#39;bootstrap&#39;][] = &#39;debug&#39;;
    $config[&#39;modules&#39;][&#39;debug&#39;] = [
        &#39;class&#39; => &#39;yii\debug\Module&#39;,
        // uncomment the following to add your IP if you are not connecting from localhost.
        //&#39;allowedIPs&#39; => [&#39;127.0.0.1&#39;, &#39;::1&#39;],
    ];

    $config[&#39;bootstrap&#39;][] = &#39;gii&#39;;
    $config[&#39;modules&#39;][&#39;gii&#39;] = [
        &#39;class&#39; => &#39;yii\gii\Module&#39;,
        // uncomment the following to add your IP if you are not connecting from localhost.
        //&#39;allowedIPs&#39; => [&#39;127.0.0.1&#39;, &#39;::1&#39;],
    ];
}

return $config;

3. Controllers under the api component

Now we are Create a new SiteControllers.php under Modules/api/controllers with the following content:

<?php

namespace app\modules\api\controllers;

use yii\web\Controller;


class SiteController extends Controller
{
    public function actionIndex()
    {
        echo "hello world";
    }
}

4. Browser access

Finally, the browser accesses this actionIndex. The browser enters: http:// localhost/basic/web/index.php?r=api/site/index

Done!
