Image 当我尝试缓存私有图像(带有修改的标题的操作)时,标题将被忽略
我有以下行动:Image 当我尝试缓存私有图像(带有修改的标题的操作)时,标题将被忽略,image,zend-framework,caching,http-headers,zend-cache,Image,Zend Framework,Caching,Http Headers,Zend Cache,我有以下行动: public function viewImageAction() { $this->_helper->layout()->disableLayout(); $this->_helper->viewRenderer->setNoRender(); $filename = sanitize_filename($this->_request->getParam('file'), 'jpg'); $dat
public function viewImageAction()
{
$this->_helper->layout()->disableLayout();
$this->_helper->viewRenderer->setNoRender();
$filename = sanitize_filename($this->_request->getParam('file'), 'jpg');
$data = file_get_contents(APPLICATION_PATH . '/../private-files/fans-pictures/' . $filename);
$this->getResponse()
->setHeader('Content-type', 'image/jpeg')
->setBody($data);
}
在我的index.php中,在应用程序启动之前,我有:
/** Zend Cache to avoid unecessary application load **/
require_once 'Zend/Cache.php';
$frontendOptions = array(
'lifetime' => 3600,
'default_options' => array(
'cache' => $cache_flag,
'cache_with_cookie_variables' => true,
'make_id_with_cookie_variables' => false),
'regexps' => array(
'^(/.+)?/admin/?' => array('cache' => false),
'^(/.+)?/pictures/view-image/?' => array('cache' => true),
'^(/.+)?/authentication/?' => array('cache' => false),
'^(/.+)?/fan-profile/?' => array('cache' => false),
'^(/.+)?/fan-registration/?' => array('cache' => false))
);
$backendOptions = array(
'cache_dir' => APPLICATION_PATH . '/cache/pages/');
$cache = Zend_Cache::factory(
'Page', 'File', $frontendOptions, $backendOptions
);
$cache->start();
缓存工作正常,只是如果我尝试访问url,比如public/admin/pictures/view image/file/63.jpg
头文件带有text/html
而不是image/jpeg
我做错什么了吗
已编辑
我试过:
'memorize_headers' => array('Content-type')
但没什么
另外,我注意到这种类型的缓存(在应用程序启动之前)不能在管理区域上完成,因为应用程序需要运行和检查会话。因此,我需要尽快把查奇,以避免所有涉及组件的负荷
有什么建议吗?解决方案 问题在于
memory_headers
参数的位置
我试着这样做:
$frontendOptions = array(
'lifetime' => 3600,
'default_options' => array(
'cache' => $cache_flag,
'cache_with_cookie_variables' => true,
'memorize_headers' => array('Content-Type', 'Content-Encoding'),
'make_id_with_cookie_variables' => false),
'regexps' => array(
'^(/.+)?/admin/?' => array('cache' => false),
'^(/.+)?/admin/pictures/view-image/?' => array('cache' => true),
'^(/.+)?/authentication/?' => array('cache' => false),
'^(/.+)?/fan-profile/?' => array('cache' => false),
'^(/.+)?/fan-registration/?' => array('cache' => false))
);
此项的正确位置不在默认\u选项中
键:
$frontendOptions = array(
'lifetime' => 3600,
'memorize_headers' => array('Content-Type', 'Content-Encoding'),
'default_options' => array(
'cache' => $cache_flag,
'cache_with_cookie_variables' => true,
//'cache_with_session_variables' => true,
'make_id_with_cookie_variables' => false),
'regexps' => array(
'^(/.+)?/admin/?' => array('cache' => false),
'^(/.+)?/admin/pictures/view-image/?' => array('cache' => true),
'^(/.+)?/authentication/?' => array('cache' => false),
'^(/.+)?/fan-profile/?' => array('cache' => false),
'^(/.+)?/fan-registration/?' => array('cache' => false))
);
现在它可以工作了。你能检查一个保存的缓存文件,看看它是否真的存储了标题吗?您应该能够找到名为“headers”
“…;s:7:“headers”;a:0:{}的序列化项}…
这是一个未保存头的示例。如果不保存头,则会出现另一个问题。如果保存头,则需要找出它们未被重放的原因。@darryl-e-clarke在元缓存文件中我有以下内容:a:4:{s:4:“哈希”;I:1472989423;s:5:“mtime”;I:1290795482;s:6:“过期”;I:1290799082;s:4:“标记“;a:0:{}
