我想做这样的事情:
if (isset($_SERVER['HTTP_IF_MODIFIED_SINCE'])) {
header('HTTP/1.1 304 Not Modified');
exit;
}
...... other code .....
以这种方式打字:
public function imageAction()
{
$request = $this->getRequest();
$response = $this->getResponse();
if ($request->getHeader('IF_MODIFIED_SINCE')) {
$response->setHttpResponseCode(304);
return;
}
var_dump($request->getHeaders());
$response->setHeader('Last-Modified', gmdate('D, d M Y H:i:s', time()).' GMT');
var_dump($response->getHeaders());
echo '11111';
exit;
希望结果读者必须像

但始终是:

或者我必须使用zend_cache?

似乎工作正常。尝试这两个动作进行测试。您需要将域名设置为下面的“yourdomain
”。
public function headerAction()
{
$response = $this->getResponse();
$request = $this->getRequest();
if ($request->getHeader('IF-MODIFIED-SINCE')) {
$response->setHttpResponseCode(304);
return;
}
$response->setHeader('Pragma', 'public', true);
$response->setHeader('Cache-control', 'max-age=' . 60*60*24*14, true);
$response->setHeader('Last_Modified', gmdate('D, d M Y H:i:s', time()).' GMT', true);
// don't exit or die here or Zend Framework won't send our $response or headers
// If you don't want to render a script, uncomment the two lines below
// $this->_helper->viewRenderer->setNoRender();
// $this->_helper->layout->disableLayout();
}
public function clientAction()
{
$client = new Zend_Http_Client('http://yourdomain/test/header');
$client->setHeaders('If-Modified-Since', 'Sat, 29 Oct 1994 19:43:31 GMT');
$response = $client->request();
Zend_Debug::dump($response->getStatus()); //prints 304
Zend_Debug::dump($response->getHeaders());
exit;
}
