修改 app\config\main-local.php 文件即可：

$config = [    'components' => [        'request' => [            // !!! insert a secret key in the following (if it is empty) - this is required by cookie validation            'cookieValidationKey' => 'UWWauIS1-qTAJUUTavkwkJSRC9gjF5oM',        ]    ],]; if (!YII_ENV_TEST) {    // configuration adjustments for 'dev' environment    $config['bootstrap'][] = 'debug';    $config['modules']['debug'] = [        'class' => 'yii\debug\Module',        'allowedIPs' => ['127.0.0.1', '::1', '192.168.1.*'] //Debug 工具栏出现403禁止访问按需调整这里    ];     $config['bootstrap'][] = 'gii';    $config['modules']['gii'] = [        'class' => 'yii\gii\Module',        'allowedIPs' => ['127.0.0.1', '::1', '192.168.1.*'] // GII访问出现403禁止访问按需调整这里    ];} return $config;
