yii2打开gii工具的方法

入口文件index.php

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

在配置config文件夹的web.php或main.php、main-local.php文件中包含以下内容

if (!YII_ENV_TEST) {
    // 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',
    ];
}

如果开启了url美化，访问地址会产生变化

'urlManager' => [
    'enablePrettyUrl'     => true,
    'showScriptName'      => false,
    'enableStrictParsing' => false,
    'rules' => [
    ],
],

访问地址：

http://localhost/gii
http://localhost/index?r=gii
