I am using an extension from a testing framework that is supposed to build up some indices and fill them with data on my elastic server.
The extension works perfectly well with a demo server that the company behind the extension gives us access to, containing just an elasticsearch instance.
Although when we target our elasticsearch server we get the error of :
application/x-www-form-urlencoded not supported.
That got me thinkng and used some more advanced queries though curl:
The simple curl "http://136.243.xx.xx:9200/ returns :
{
"name" : "Artorias",
"cluster_name" : "some name",
"cluster_uuid" : "some uid",
"version" : {
"number" : "6.0.0",
"build_hash" : "8f0685b",
"build_date" : "2017-11-10T18:41:22.859Z",
"build_snapshot" : false,
"lucene_version" : "7.0.1",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}
Then trying out a query like :
curl "http:-XGET 'http://136.243.xx.xx:9200/_cat/indices?v&pretty'
or
curl "http://136.243.xx.xx:9200/_search" -d '{"query": {"match_all": {}}}'
return :
{"error":"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406}
Could some http.cors directive help solve this?(i am still reading about this).
Hints to any direction?
