我发现了一个检查url状态的脚本。现在我正在尝试将其与wordpress整合。这是代码:每天用wordpress执行php脚本
<?php
/*
Plugin Name: checkOnline Status
Version: 0.1
*/
add_action('cO_cron_hook', 'CheckRemoteService');
if(!wp_next_scheduled('cO_cron_hook')) {
wp_schedule_event(time(), 'daily', 'cO_cron_hook');
}
register_deactivation_hook(__FILE__, 'bl_deactivate');
function bl_deactivate() {
$timestamp = wp_next_scheduled('cO_cron_hook');
wp_unschedule_event($timestamp, 'cO_cron_hook');
}
function CheckRemoteService($atts) {
extract(shortcode_atts(array(
'url' => 'http://',
'cache' => '600', // 60*10 (10 minutes)
'online' => 'Online', // Custom online msg
'offline' => 'Offline' // Custom online msg
), $atts));
$CachedStatus = 'cstatus_' . $url;
$cachedposts = get_transient($CachedStatus);
if ($cachedposts !== false) {
return $cachedposts;
} else {
// Sometimes its best to change to a custom agent message
// so you know where requests are coming from.
$agent = "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)";
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch,CURLOPT_VERBOSE,false);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_NOBODY, 1);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch,CURLOPT_SSLVERSION,3);
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST, FALSE);
curl_exec($ch);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
if($httpcode >= 200 && $httpcode < 400) {
return $online;
} else {
return $offline;
}
set_transient($CachedStatus, $return, $cache);
return $return;
}
}
add_shortcode('checkmyurl','CheckRemoteService');
?>
我想是每天只运行一次该代码。如何在刷新或访问使用简码的页面时使其无法运行?我需要大约50个站点的显示状态,并且页面需要超过10秒才能加载。 对不起,这个简单的问题(我是一个noob这个),但我找不到解决方案。 谢谢。
编辑。使用http://wordpress.org/plugins/crony/
名称['cO _ ** cron ** _ hook'](https://en.wikipedia.org/wiki/Cron)是一个提示。 – PeeHaa
WordPress的cron似乎有用,功能是预定的。我的问题是避免它在进入网站和刷新页面时加载。谢谢。 –
