Yii2访问Debug

1.项目安装debug工具，php composer.phar require --prefer-dist yiisoft/yii2-debug

2.配置web/index.php

 defined('YII_DEBUG') or define('YII_DEBUG', true);
 defined('YII_ENV') or define('YII_ENV', 'dev');

　　

3.配置config/web.php

if(file_exists(__DIR__ . "/web-local.php")) {
    $localConfig = require __DIR__ . "/web-local.php";
    $config = ArrayHelper::merge($config, $localConfig);
}

　　

4.增加web-local.php

<?php

$localConfig = [
    'components' => [
        'log' => [
            'traceLevel' => YII_DEBUG ? 3 : 0,
            'targets' => [
                [
                    'class' => 'yii\log\FileTarget',
                    'levels' => ['error', 'warning'],
                ],
            ],
        ],
    ],
];

if (YII_ENV_DEV) {
    // configuration adjustments for 'dev' environment
    $localConfig['bootstrap'][] = 'debug';
    $localConfig['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'],
        'allowedIPs' => ['*'],
    ];

    $localConfig['bootstrap'][] = 'gii';
    $localConfig['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 $localConfig;

　　

5.设置runtime目录为可读写
