yii框架如何访问自定义模块下的controller

互联网 20-2-26

问题：

Site控制器里面的action如何访问？如图：

解决方法：

1、建立目录

首先建立如上的目录结构，在api下的以及目录有三个文件夹和一个文件Module.php，这个php文件内容如下：

<?php  namespace app\modules\api;  /**  * api module definition class  */ class Module extends \yii\base\Module {     /**      * @inheritdoc      */     public $controllerNamespace = 'app\modules\api\controllers';      /**      * @inheritdoc      */     public function init()     {         parent::init();          // custom initialization code goes here     } }

（推荐教程：yii框架）

2、web.php

还记得项目根目录下的config文件夹下有个web.php文件么，添加如下字段：

<?php  $params = require __DIR__ . '/params.php'; $db = require __DIR__ . '/db.php';  $config = [     'id' => 'basic',     'basePath' => dirname(__DIR__),     'bootstrap' => ['log'],     'aliases' => [         '@bower' => '@vendor/bower-asset',         '@npm'   => '@vendor/npm-asset',     ],     'components' => [         'request' => [             // !!! insert a secret key in the following (if it is empty) - this is required by cookie validation             'cookieValidationKey' => 'jjsYJ_ju0W8ifOv5mY3JBMI6DOppFlo6',         ],         'cache' => [             'class' => 'yii\caching\FileCache',         ],         'user' => [             'identityClass' => 'app\models\User',             'enableAutoLogin' => true,         ],         'errorHandler' => [             'errorAction' => 'site/error',         ],         'mailer' => [             'class' => 'yii\swiftmailer\Mailer',             // send all mails to a file by default. You have to set             // 'useFileTransport' to false and configure a transport             // for the mailer to send real emails.             'useFileTransport' => true,         ],         'log' => [             'traceLevel' => YII_DEBUG ? 3 : 0,             'targets' => [                 [                     'class' => 'yii\log\FileTarget',                     'levels' => ['error', 'warning'],                 ],             ],         ],         'db' => $db,         /*         'urlManager' => [             'enablePrettyUrl' => true,             'showScriptName' => false,             'rules' => [             ],         ],         */     ],     'modules' => [         'api' => [             'class' => 'app\modules\api\Module',         ],     ],     'params' => $params, ];  if (YII_ENV_DEV) {     // configuration adjustments for 'dev' environment     $config['bootstrap'][] = 'debug';     $config['modules']['debug'] = [         'class' => 'yii\debug\Module',         // uncomment the following to add your IP if you are not connecting from localhost.         //'allowedIPs' => ['127.0.0.1', '::1'],     ];      $config['bootstrap'][] = 'gii';     $config['modules']['gii'] = [         'class' => 'yii\gii\Module',         // uncomment the following to add your IP if you are not connecting from localhost.         //'allowedIPs' => ['127.0.0.1', '::1'],     ]; }  return $config;

3、api组件下的controllers

现在我们在Modules/api/controllers下新建一个SiteControllers.php,内容如下：

<?php  namespace app\modules\api\controllers;  use yii\web\Controller;   class SiteController extends Controller {     public function actionIndex()     {         echo "hello world";     } }

4、浏览器访问

最后就是浏览器访问这个actionIndex了，浏览器输入： http://localhost/basic/web/index.php?r=api/site/index
