Yii2访问自定义模块下的controller
之前，由于所要访问的controller都是位于根目录下的controllers目录下，就像下面这样：
此时，我们可以直接通过 localhost/basic/web/index.php?r=dao/index 来访问图中DaoController.php里的actionIndex。
但是如果，我们将controller、view等有关联的独立出来作为一个模块Modules，那么又将怎样去处理呢。
就像上面这样，这个Site控制器里面的action又将如何访问呢。
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：
'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;
为了避免看的时候出错，上面红字的“键”是出于同一级的，红字加粗的是我们为modules添加的相关配置信息，相当于在应用中注册了刚才定义的组件(api)。
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：
