我创建了以下函数来访问twitter api并检索最新的tweet。它工作得很好，我可以在我的网站的页脚显示最新的推文，而不是发生在每个页面加载，我想设置一个cron工作来获取最新的推文每小时。
我没有使用wp cron之前，所以想知道是否有人可以建议我如何最好地做到这一点?
function buildBaseString($baseURI, $method, $params) {
$r = array();
ksort($params);
foreach($params as $key=>$value){
$r[] = "$key=" . rawurlencode($value);
}
return $method."&" . rawurlencode($baseURI) . '&' . rawurlencode(implode('&', $r));
}
function buildAuthorizationHeader($oauth) {
$r = 'Authorization: OAuth ';
$values = array();
foreach($oauth as $key=>$value)
$values[] = "$key='"" . rawurlencode($value) . "'"";
$r .= implode(', ', $values);
return $r;
}
function hs_tweets_fetch($screen_name = 'XXXXXXXXXXX', $count = 1) {
$config = array(
'oauth_access_token' => 'XXXXXXXXXXXXXX',
'oauth_access_token_secret' => 'XXXXXXXXXXXXXXX',
'consumer_key' => 'XXXXXXXXXXXXXXXXXXXXXX',
'consumer_secret' => 'XXXXXXXXXXXXXXXX',
'base_url' => 'https://api.twitter.com/1.1/'
);
$url = 'statuses/user_timeline.json?screen_name=' . $screen_name . '&count=' . $count;
$url_parts = parse_url($url);
parse_str($url_parts['query'], $url_arguments);
$full_url = $config['base_url'].$url; // Url with the query on it.
$base_url = $config['base_url'].$url_parts['path']; // Url without the query.
$oauth = array(
'oauth_consumer_key' => $config['consumer_key'],
'oauth_nonce' => time(),
'oauth_signature_method' => 'HMAC-SHA1',
'oauth_token' => $config['oauth_access_token'],
'oauth_timestamp' => time(),
'oauth_version' => '1.0'
);
$base_info = buildBaseString($base_url, 'GET', array_merge($oauth, $url_arguments));
$composite_key = rawurlencode($config['consumer_secret']) . '&' . rawurlencode($config['oauth_access_token_secret']);
$oauth_signature = base64_encode(hash_hmac('sha1', $base_info, $composite_key, true));
$oauth['oauth_signature'] = $oauth_signature;
$header = array(
buildAuthorizationHeader($oauth),
'Expect:'
);
$options = array(
CURLOPT_HTTPHEADER => $header,
//CURLOPT_POSTFIELDS => $postfields,
CURLOPT_HEADER => false,
CURLOPT_URL => $full_url,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_SSL_VERIFYPEER => false
);
$feed = curl_init();
curl_setopt_array($feed, $options);
$result = curl_exec($feed);
$info = curl_getinfo($feed);
curl_close($feed);
if ($info['http_code'] == 200) {
$result = json_decode($result);
} else {
$result = false;
}
return $result;
}
您必须安排每小时的cron，然后必须在您的数据库中保存tweet。获取tweet的Cron可以是这样的。
if (!wp_next_scheduled('hs_tweets_fetch_cron'))
{
wp_schedule_event(time(), 'hourly', 'hs_tweets_fetch_cron');
}
add_action('hs_tweets_fetch_cron', 'hs_tweets_fetch');
function hs_tweets_fetch_cron()
{
1- // fetch the tweets
2- // Save/update the tweets in Wordpress options meta or custom table
}
然后在页脚显示数据库表中的tweets
对于这种类型的工作，我将使用WordPress瞬态api而不是cron。
Transient将产生与
