请求体方式请求elasticsearch

下面是使用使用请求body 方法:

GET /test/_search
{
  "query": { "match_all": {} },
  "sort": [
    { "account_number": "asc" }
     
  ],
  "fields":  [ "account_number", "firstname", "lastname" ]
}






{
  "took": 4,
  "timed_out": false,

  },

        },
        "sort": [

        ]
      },
      {

        "sort": [
          99
        ]
      }
    ]
  }
}

利用perl 实现:

[elk@node01 api]$ cat a10.pl 
##发送消息
use  LWP::UserAgent; 
use LWP;
use Encode;
use LWP::Simple;
use LWP::UserAgent;
use HTTP::Cookies;
use HTTP::Headers;
use HTTP::Response;
use Encode;
use URI::Escape;
use URI::URL;
use JSON;
use Data::Dumper;
  my $ua = LWP::UserAgent->new;
     $ua->agent("Mozilla/5.0 (Windows NT 6.1; rv:30.0) Gecko/20100101 Firefox/30.0");
  my $cookie_jar = HTTP::Cookies->new(
     file=>'lwp_cookies.txt',
     autosave=>1,
     ignore_discard=>1);
     $ua->cookie_jar($cookie_jar);  
   my $login_url ="http://192.168.137.2:9200/test/_search";  
   my $post ={
  "query" => { "match_all" => {} },
  "sort" => [
    { "account_number" => "asc" }
     
  ],
  "fields" =>  [ "account_number", "firstname", "lastname" ]
};

        
    
    use JSON qw(encode_json);  
    $json_string = encode_json($post);  
  
    my $req = HTTP::Request->new(  
        'POST' => $login_url
    );  
    $req->content_type('application/json; charset=UTF-8')  
      ;    #post请求,如果有发送参数，必须要有这句  
    $req->content("$json_string");    #发送post的参数  
    my $res = $ua->request($req);  
    print $res->content()."
";            #获取的是响应正文
