jquery - elasticsearch.js client connection refused: Access-Control-Allow-Origin not recognized? -

i've been trying ping locally running elasticsearch using elasticsearch.jquery.min.js , "no living connection" error each time.

---

eta: in chrome see looks pretty low level "connection refused". i'm developing on macos x, , browser points @ page via http://localhost/~myuserid/sitename/. i'm accessing localhost:9200 falls under cross domain cors requirements.

i see following error in chrome console:

xmlhttprequest cannot load http://localhost:9200/?hello=elasticsearch!. no 'access-control-allow-origin' header present on requested resource. origin 'http://localhost' therefore not allowed access. 

per http://enable-cors.org/server_apache.html i've added following /etc/apache2/httpd.conf:

<directory />     header set access-control-allow-origin "localhost:9200"     allowoverride none     require denied </directory> 

and run

$ sudo apachectl -t $ sudo apachectl -k graceful 

but error persists. there setting i'm overlooking?

i'm noob elasticsearch.js. there need on elasticsearch side allow client connections browser, or something?

i'm following the book in ping attempt:

var client = new $.es.client({   hosts: 'localhost:9200'   });  client.ping(   {     requesttimeout: infinity,     // undocumented params appended query string     hello: "elasticsearch!"     },   function (error) {     if (error) {       console.error('elasticsearch cluster down!');       console.error(error);     } else {       console.log('all well');       }     }   ); 

but i'm getting following error(s):

"warning: 2015-10-10t07:00:16z"        elasticsearch.jquery.min.js:14:10575   unable revive connection: http://localhost:9200/  "warning: 2015-10-10t07:00:16z"        elasticsearch.jquery.min.js:14:10575   no living connections 

i can connect using curl on command line fine, pull , insert data, etc.:

$ curl "localhost:9200/_cat/indices?v" health status index             pri rep docs.count docs.deleted store.size pri.store.size   green  open   fuddle              1   0          3            0     12.9kb         12.9kb                                                 green  open   faddle              1   0          0            0       144b           144b

eta additional diagnostics. google chrome shows following network traces failing attempt. @ http layer response looks it's happening.

general   remote address:[::1]:9200   request url:http://localhost:9200/?hello=elasticsearch!   request method:head   status code:200 ok response headers   content-length:0   content-type:text/plain; charset=utf-8 request headers   accept:text/plain, */*; q=0.01   accept-encoding:gzip, deflate, sdch   accept-language:en-us,en;q=0.8   connection:keep-alive   content-length:0   host:localhost:9200   origin:http://localhost   referer:http://localhost/~browsc3/opticon/   user-agent:mozilla/5.0 (macintosh; intel mac os x 10_10_5) applewebkit/537.36 (khtml, gecko) chrome/45.0.2454.101 safari/537.36 query string parameters   view url encoded   hello:elasticsearch! 

the same request in wget:

i'm @ loss go here. see lots of references error on teh googlz, none of circumstances seem remotely similar. feels i'm hitting misconfiguration, can't find indicate is.

well, tough one.

here's fixed it:

per http://enable-cors.org/server_apache.html, in /etc/apache2/httpd.conf, configure access-control-allow-origin:

<directory />     # add following line enable cors connect local elasticsearch.     header set access-control-allow-origin "localhost:9200"     allowoverride none     require denied </directory> 

per https://jsbroadcast.com/elastic-search-cors/, in elasticsearch-1.7.0/config/elasticsearch.yml add:

http.cors.enabled : true //  http.cors.allow-origin: "/.*/" http.cors.allow-methods : options, head, get, post, put, delete http.cors.allow-headers : "x-requested-with,x-auth-token,content-type, content-length, authorization" 

i can run client.ping call without error.
