J'essaie d'utiliser ElasticSearch avec le framework Codeigniter.
Ce que j'ai fait, c'est installer ElasticSearch et copier ( :P ) une bonne bibliothèque PHP trouvée sur le web dans les bibliothèques CI :
class Elasticsearch {
public $config_file = 'elasticsearch';
public $index;
function __construct($index = false){
$CI =& get_instance();
$CI->config->load($this->config_file);
$this->server = $CI->config->item('es_server');
}
function call($path, $http = array()){
if (!$this->index) throw new Exception('$this->index needs a value');
return json_decode(file_get_contents($this->server . '/' . $this->index . '/' . $path, NULL, stream_context_create(array('http' => $http))));
}
//curl -X PUT http://localhost:9200/{INDEX}/
function create(){
$this->call(NULL, array('method' => 'PUT'));
}
//curl -X DELETE http://localhost:9200/{INDEX}/
function drop(){
$this->call(NULL, array('method' => 'DELETE'));
}
//curl -X GET http://localhost:9200/{INDEX}/_status
function status(){
return $this->call('_status');
}
//curl -X GET http://localhost:9200/{INDEX}/{TYPE}/_count -d {matchAll:{}}
function count($type){
return $this->call($type . '/_count', array('method' => 'GET', 'content' => '{ matchAll:{} }'));
}
//curl -X PUT http://localhost:9200/{INDEX}/{TYPE}/_mapping -d ...
function map($type, $data){
return $this->call($type . '/_mapping', array('method' => 'PUT', 'content' => $data));
}
//curl -X PUT http://localhost:9200/{INDEX}/{TYPE}/{ID} -d ...
function add($type, $id, $data){
echo $this->call($type . '/' . $id, array('method' => 'PUT', 'content' => $data));
}
//curl -X GET http://localhost:9200/{INDEX}/{TYPE}/_search?q= ...
function query($type, $q){
return $this->call($type . '/_search?' . http_build_query(array('q' => $q)));
}
}
puis j'essaie de créer des index et de les récupérer simplement :
$this->load->library('elasticsearch');
$this->elasticsearch->index = 'comments';
$this->elasticsearch->create();
$data = '{author:jhon,datetime:2001-09-09 00:02:04}';
$this->elasticsearch->add($type ='details',$id = '1',$data);
Quand j'exécute ce code, il me montre des erreurs :
A PHP Error was encountered
Severity: Warning
Message: file_get_contents(http://localhost:9200/comments/) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request

je me trompe ou j'ai raté quelque chose ? désolé mais je suis novice en elasticsearch et aussi un peu en php :P
parce que si je vais à :
http://localhost:9200/comments/details/1
//it prints in window
{"_index":"comments","_type":"details","_id":"1","exists":false}
