弹性搜索和Codeigniter（PHP） [英] Elastic search and Codeigniter (PHP)

问题描述

我正在尝试使用ElasticSearch与Codeigniter框架。

我所做的只是安装ElasticSearch并复制（：P）一个在网络上找到的好的PHP库CI库：

  class Elasticsearch {
 
 public $ config_file ='elasticsearch'; 
 public $ index; 
 
函数__construct（$ index = false）{
 $ CI =& get_instance（）; 
 $ CI-> config-> load（$ this-> config_file）; 
 $ this-> server = $ CI-> config-> item（'es_server'）; 
 
} 
 
函数调用（$ path，$ http = array（））{
 if（！$ this-> index）throw new Exception $ this-> index需要一个值'）; 
 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-> ;调用（ '_状态'）; 
} 
 
 // curl -X GET http：// localhost：9200 / {INDEX} / {TYPE} / _count -d {matchAll：{}} 
函数计数（$ 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'=> $数据））; 
} 
 
 // curl -X GET http：// localhost：9200 / {INDEX} / {TYPE} / _search？q = ... 
 function query类型，$ q）{
 return $ this-> call（$ type。'/ _search？'。http_build_query（array（'q'=> $ q）））; 
} 
} 
  

然后我正在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）; 
  

当我运行此代码时，会显示错误：

 遇到PHP错误
 
严重性：警告
 
消息：file_get_contents（http：// localhost：9200 / comments /）[function.file-get-contents]：无法打开流：HTTP请求失败！ HTTP / 1.0 400错误请求
 
文件名：libraries / Elasticsearch.php 
 
行号：19 
遇到PHP错误
 
严重性：通知
 
消息：file_get_contents（）[function.file-get-contents]：内容类型未指定假设应用程序/ x-www-form-urlencoded 
 
文件名：library / Elasticsearch.php

遇到PHP错误
 
严重性：警告

文件名：libraries / Elasticsearch.php 
 
行号：19 
  

我错误/错过了吗？对不起，我是弹性搜索的新手，还有一点PHP：P

如果我去：

  http：// localhost：9200 / comments / details / 1 
 
 //它在窗口中打印
 {_index：评论，_ type：details，_ id：1，exists：false} 
  

解决方案

我不太确定，但我的猜测将是您致电 add（）：

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

您不想在此设置值。我会假设你会在HTTP不正确的请求之前收到一个php错误，但是我会尝试这个：

  $ this- > elasticsearch->添加（ '详情'， '1'，$数据）; 
  

您的 add（）方法已经知道什么参数代表，所以你只需要传递细节。

另外

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

I'm trying using ElasticSearch with Codeigniter framework.

What i did is just install ElasticSearch and copyed ( :P ) a good PHP library found on the web to CI libraries:

    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)));
  }
}

then i'm trying creating indexes and simply retrieve them:

$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);

when i run this code it show me errors:

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

A PHP Error was encountered

Filename: libraries/Elasticsearch.php

Line Number: 19

does i'm mistaking/missed somenthing? sorry but i'm newbie about elasticsearch and also a little bit with php :P

cause if i go to:

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

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

解决方案

I'm not quite sure, but my guess would be your call to add():

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

You don't want to be setting values here. I would assume you'd get a php error before an HTTP bad request, but I would try this first:

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

Your add() method already knows what the arguments represent, so you just need to pass the details.

Also

It looks like your json might be malformed.

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

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