我从谷歌收到了下一个通知：

example.com/img/logo/t.svg (expiration not specified) example.com/img/main_background/bg_mob.jpg (expiration not specified)
为了解决这个问题，我发现了下一个行为：
public function behaviors()
{
return [
[
'class' => 'yii'filters'HttpCache',
'only' => ['index'],
'lastModified' => function ($action, $params) {
// $q = new 'yii'db'Query();
return time() + 3600;
// return $q->from('users')->max('updated_at');
},
'sessionCacheLimiter' => 'public',
// 'etagSeed' => function ($action, $params) {
// return // generate ETag seed here
// }
],
];
}
在此之后，main文档（不适用于所有请求，仅适用于/）会出现三个额外的标题：
Cache-Control:public, max-age=3600 Last-Modified:Fri, 13 May 2016 09:03:45 GMT Pragma:
Altughter集时间（）+3600，上次修改等于数据标头
如何为所有请求而不是仅为设置/所以，据我所知，谷歌希望我设置ExpireHeader？
Expire进入web文件夹中的.htaccess:
<IfModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 1 month"
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
ExpiresByType image/jpg "access plus 1 month"
ExpiresByType image/jpeg "access plus 1 month"
ExpiresByType application/javascript "access plus 1 year"
</IfModule>
此外，在yii2中，您可以设置版本（查询字符串）：
'components' => [
'assetManager' => [
'appendTimestamp' => true,
],
],

版本还是上次修改
