Yii 2.0 GII 访问404错误

网上大部分都是普通的开启和配置资料
按照网上资料配置访问localhost/index/php?r=gii 总是提示404错误

解决方法如下：
Yii基础版中的 web.php 代码如下

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'],];
}

注意这里的变量是YII_ENV_DEV 而在入口文件index.php中配置的是

defined('YII_DEBUG') or define('YII_DEBUG', true);
defined('YII_ENV') or define('YII_ENV','dev');
//需要根绝web.php中的变量YII_ENV_DEV增加对应的开启设置
defined('YII_ENV_DEV ') or define('YII_ENV_DEV ', true);require(__DIR__ . '/../vendor/autoload.php');
require(__DIR__ . '/../vendor/yiisoft/yii2/Yii.php');$config = require(__DIR__ . '/../config/web.php');(new yii\web\Application($config))->run();

2.路由配置
enablePrettyUrl 设置为false

//路由配置'urlManager' => ['enablePrettyUrl' => false,//路由的路径化 去掉 ?r='showScriptName' => false,//隐藏入口Index.php文件//'suffix' => '.html',//假后缀(fake suffix) .html'rules' => ['<controller:\w+>/<name:\w+>/<action:\w+>'=>'<controller>/<action>','company/<id:\d+>.html'=>'company/list',],],
