(PECL solr >= 0.9.2)
SolrClient::ping — Checks if Solr server is still up
Checks if the Solr server is still alive. Sends a HEAD request to the Apache Solr server.
此函数没有参数。
Returns a SolrPingResponse object on success and throws an exception on failure.
Throws SolrClientException if the client had failed, or there was a connection issue.
Throws SolrServerException if the Solr Server had failed to satisfy the request.
Example #1 SolrClient::ping() example
<?php
$options = array
(
'hostname' => SOLR_SERVER_HOSTNAME,
'login' => SOLR_SERVER_USERNAME,
'password' => SOLR_SERVER_PASSWORD,
'port' => SOLR_SERVER_PORT,
);
$client = new SolrClient($options);
$pingresponse = $client->ping();
?>
以上例程的输出类似于：
class Search extends Solr
{
protected $searchEngine;
function __construct()
{
$this->searchEngine = $this->connect();
}
public function checkAlive()
{
$searchEngine = $this->searchEngine;
if($searchEngine->ping())
{
return true;
}
else
{
return false;
}
}
}
