php - 如何停止在此 PHP 文件中缓存 .js 文件

Question

我试图阻止chatrooms.js文件被缓存，聊天的开发人员告诉我我需要通过js.php

这是代码js.php：

include_once (dirname(__FILE__).DIRECTORY_SEPARATOR.'config.php');

if (phpversion() >= '5') {
    include_once (dirname(__FILE__).DIRECTORY_SEPARATOR.'jsmin.php');
}

if (BAR_DISABLED == 1) { exit; }

if(get_magic_quotes_runtime()) { 
    set_magic_quotes_runtime(false); 
}

$mtime = microtime();
$mtime = explode(" ",$mtime);
$mtime = $mtime[1] + $mtime[0];
$starttime = $mtime; 

$HTTP_USER_AGENT = '';
$useragent = (isset($_SERVER["HTTP_USER_AGENT"]) ) ? $_SERVER["HTTP_USER_AGENT"] : $HTTP_USER_AGENT;

ob_start();

if (!empty($_REQUEST['type']) && !empty($_REQUEST['name'])) {
    $type = cleanInput($_REQUEST['type']);
    $name = cleanInput($_REQUEST['name']);
} else {
    $type = 'core';
    $name = 'default';
}

$cbfn = '';

if (!empty($_REQUEST['callbackfn'])) {
    $cbfn = $_REQUEST['callbackfn'];
} 

if (file_exists(dirname(__FILE__).DIRECTORY_SEPARATOR.'cache'.DIRECTORY_SEPARATOR.$cbfn.$theme.$lang.$type.$name.'.js') && DEV_MODE != 1) {

    if (!empty($_SERVER['HTTP_IF_MODIFIED_SINCE']) && strtotime($_SERVER['HTTP_IF_MODIFIED_SINCE']) == filemtime(dirname(__FILE__).DIRECTORY_SEPARATOR.'cache'.DIRECTORY_SEPARATOR.$cbfn.$theme.$lang.$type.$name.'.js')) {
        header("HTTP/1.1 304 Not Modified");
        exit;
    }

    readfile(dirname(__FILE__).DIRECTORY_SEPARATOR.'cache'.DIRECTORY_SEPARATOR.$cbfn.$theme.$lang.$type.$name.'.js');
    $js = ob_get_clean();

} else {

    if (($type != 'core' || $name != 'default') && $type != 'external') {

        if ($type == 'core') {
            include_once (dirname(__FILE__).DIRECTORY_SEPARATOR."js".DIRECTORY_SEPARATOR.$name.".js");
        } else {

        } else if ($hideOffline == 1) {

我需要在这里的某个地方指示禁用缓存/modules/chatrooms/chatrooms.js

但看不到确切的位置或放置什么......有什么想法吗？

改变：

header('Expires: '.gmdate("D, d M Y H:i:s", time() + 3600*24*365).' GMT');

至：

header('Expires: '.gmdate("D, d M Y H:i:s", time() - 3600*24*365).' GMT');

这样，文件将在过去而不是将来过期。

更新： @Salman A，指出了IF-MODIFIED-SINCE检查。你需要这样做：

改变

if (!empty($_SERVER['HTTP_IF_MODIFIED_SINCE']) && strtotime($_SERVER['HTTP_IF_MODIFIED_SINCE']) == filemtime(dirname(__FILE__).DIRECTORY_SEPARATOR.'cache'.DIRECTORY_SEPARATOR.$cbfn.$theme.$lang.$type.$name.'.js')) {

至：

if (0){//!empty($_SERVER['HTTP_IF_MODIFIED_SINCE']) && strtotime($_SERVER['HTTP_IF_MODIFIED_SINCE']) == filemtime(dirname(__FILE__).DIRECTORY_SEPARATOR.'cache'.DIRECTORY_SEPARATOR.$cbfn.$theme.$lang.$type.$name.'.js')) {

这将通过将表达式转换为来禁用该代码块FALSE，如果您需要再次启用它，请删除0){//.
