javascript - Elasticsearch https cors enabled but still getting No 'Access-Control-Allow-Origin' header is present on the requested resource -

-

i have enabled settings cors in index called myindex, here settings it. when try pull data elasticsearch simple javascript cors headers set error

xmlhttprequest cannot load http://elasticsearchdomain.com:9200/myindex/_search/. response preflight request doesn't pass access control check: no 'access-control-allow-origin' header present on requested resource. origin 'http://localhost:8000' therefore not allowed access.

i running javascript include script run when open html page through python server.

here javascript im trying use pull data elasticsearch

var url = "http://elasticsearchdomain.com:9200/myindex/_search/"; var method = "post"; var postdata = '{"query": { "filtered": { "query": { "query_string": { "query": "*", "analyze_wildcard": true } }, "filter": { "bool": { "must": [ { "query": { "query_string": { "query": "*", "analyze_wildcard": true } } }, { "range": { "report_time": { "gte": 1458409392443, "lte": 1461001392443 } } } ], "must_not": [] } } } }, "size": 0, "aggs": { "2": { "date_histogram": { "field": "report_time", "interval": "12h", "pre_zone": "-07:00", "pre_zone_adjust_large_interval": true, "min_doc_count": 1, "extended_bounds": { "min": 1458409392443, "max": 1461001392443 } }, "aggs": { "3": { "terms": { "field": "pool_name", "size": 20, "order": { "_count": "desc" } } } } } } }';  // want async = true. // otherwise, it'll block execution waiting server response. var async = true;  var request = new xmlhttprequest();  // specifies how http response handled.  request.onload = function () {     // can kinds of information http response.    var status = request.status; // http response status, e.g., 200 "200 ok"    var data = request.responsetext; // returned data, e.g., html document. }  request.open(method, url, async); request.setrequestheader('access-control-allow-headers', '*'); request.setrequestheader('access-control-allow-origin', '*'); request.setrequestheader("content-type", "application/json;charset=utf-8");  // sends request server. request.send(postdata);

those not index specific settings.

the cors settings should placed in elasticsearch.yml config file of every node in es cluster , cluster restarted. see here more this.

i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
