已补充，谢谢

components：

//url美化
'urlManager' => [
    'enablePrettyUrl' => true,
    'showScriptName' => false,
    'rules' => [
            '<controller:\w+><action:\w+>/<id:\d+>/<p:\d+>'=>'<controller>/<action>',
        ],
],

nginx：

location / {
    # Redirect everything that isn't a real file to index.php
    try_files $uri $uri/ /index.php?$args;
}

在 控制器 里面 var_dump($this->id, $this->action->id);

在 视图 里面 var_dump($this->context->id, $this->context->action->id);
