本文實例講述了Yii2框架配置文件(Application屬性)與調(diào)試技巧。分享給大家供大家參考，具體如下：
配置文件
Yii2的主要配置文件config\web.php:
?php
$params = require(__DIR__ . '/params.php');
$config = [
'id' => 'basic',
'basePath' => dirname(__DIR__),
'bootstrap' => ['log'],
'components' => [
'request' => [
// !!! insert a secret key in the following (if it is empty) - this is required by cookie validation
'cookieValidationKey' => 'aldjaldjaldjaljd',
],
'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' => require(__DIR__ . '/db.php'),
'urlManager' => [
'enablePrettyUrl' => true,
'showScriptName' => false,
'rules' => [
],
],
],
'params' => $params,
];
if (YII_ENV_DEV) {
// configuration adjustments for 'dev' environment
$config['bootstrap'][] = 'debug';
$config['modules']['debug'] = [
'class' => 'yii\debug\Module',
];
$config['bootstrap'][] = 'gii';
$config['modules']['gii'] = [
'class' => 'yii\gii\Module',
];
}
return $config;
最后返回的一個數(shù)組，數(shù)組的key都是Application的屬性。
我們到控制器中來訪問一下：
public function actionIndex()
{
echo \Yii::$app->id,'br>';
echo \Yii::$app->name,'br>';
exit;
return $this->render('index',['username'=>'張三','age'=>22]);
}
在入口文件web/index.php 里會加載這個config.php 配置文件，來創(chuàng)建一個Application
#... $config = require(__DIR__ . '/../config/web.php'); (new yii\web\Application($config))->run();
調(diào)試技巧
助手類Yii，服務(wù)于整個框架，提供一些基礎(chǔ)方法：記錄日志、調(diào)試等
\Yii:warning()日志文件runtime/logs/app.log
\Yii::error()
\Yii::info()
\Yii:trace('調(diào)試內(nèi)容','test')
