Yii2 When setting enablePrettyUrl, the setting method of defaultAction

在使用Yii2时，如果启用了美化的Url，则访问http://www.aaa.com ，不能直接显示http://www.aaa.com/site/index.html内容。 这时候需要配置rules

'urlManager' => [ 
						'enablePrettyUrl' => true,
						'showScriptName' => false,
						'enableStrictParsing' => true,
						'suffix' => ".html",
						'rules' => [ '' => 'site/index', // 如果没有这里，则访问域名不能直接打开默认Action
						] 
				] 

Of course, if the default controller and action used are not site/index, then you need to set it here:

$config = [ 
		'id' => 'basic',
		
		//'defaultRoute'=>'site/index',
...

The above introduces the setting method of defaultAction in Yii2 when setting enablePrettyUrl, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
