我正在尝试将 ElasticSearch 与 Codeigniter 框架结合使用。

我所做的只是安装 ElasticSearch 并将在网上找到的一个很好的 PHP 库复制 (:P) 到 CI 库:

    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)));
}
}

然后我尝试创建索引并简单地检索它们:

$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);

当我运行这段代码时,它显示错误:

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

Filename: libraries/Elasticsearch.php

Line Number: 19
A PHP Error was encountered

Severity: Notice

Message: file_get_contents() [function.file-get-contents]: Content-type not specified assuming application/x-www-form-urlencoded

Line Number: 19
A PHP Error was encountered

Severity: Warning

Message: file_get_contents(http://localhost:9200/comments/details/1) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request

Line Number: 19

我是不是误会/遗漏了什么?抱歉,我是 elasticsearch 的新手,也有点 php :P

因为如果我去:

http://localhost:9200/comments/details/1

//it prints in window
{"_index":"comments","_type":"details","_id":"1","exists":false}

最佳答案

我不太确定,但我猜你会调用 add():

$this->elasticsearch->add($type ='details',$id = '1',$data);

您不想在这里设置值。我会假设你会在 HTTP 错误请求之前收到一个 php 错误,但我会先尝试这个:

$this->elasticsearch->add('details','1',$data);

您的 add() 方法已经知道参数代表什么,因此您只需传递详细信息即可。

还有

看起来您的 json 格式可能有误。

// change
$data = '{author:jhon,datetime:2001-09-09 00:02:04}';

// to
$data = '{author:"jhon",datetime:2001-09-09 00:02:04}';
