[英]Slim v3 duplicates cache-control header
I have to return a specific cache-control header ( Cache-Control: public, max-stale=13910400
) but when run this, I get this: 我必须返回一个特定的缓存控制头(
Cache-Control: public, max-stale=13910400
),但是当运行它时,我得到这个:
Cache-control has been duplicated, but I only need custom values. 缓存控制已被复制,但我只需要自定义值。
$newResponse = $response->withHeader('Cache-Control', 'public, max-stale=13910400')->withJson($appInfo);
return $newResponse;
I tried this but it doesn't work (just for testing): 我试过这个,但它不起作用(仅用于测试):
$newResponse = $response->withoutHeader('Cache-Control')->withHeader('Cache-Control', 'public, max-stale=13910400')->withJson($appInfo);
return $newResponse;
How can I set the header correctly? 如何正确设置标题?
Thank you 谢谢
I suspect that you might have a middleware problem. 我怀疑你可能有中间件问题。
Your code above does produce the correct output. 上面的代码确实产生了正确的输出。
$app->get('/test', function ($req, $res, $args) {
header_remove("Cache-Control"); //Edit <--
$newResponse = $res->withHeader('Cache-Control', 'public, max-stale=13910400')->withJson(["message" => "Test"]);
return $newResponse;
});

从代码中删除缓存控件,并在.htaccess文件中添加以下代码
<filesMatch "\\\\.(html|htm|php)$"> Header set Cache-Control "max-age=1, private, must-revalidate" </filesMatch>
