I am trying to test an index from my local machine. I created a simple HTML page with a query box that sends the query to ES using the elasticsearch.js client. Both the index and the browser are on my desktop, so there shouldn't be a cross origin problem, but I keep getting an error that states:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:9200/portal/book/_search?q=title%3Ahistoire. This can be fixed by moving the resource to the same domain or enabling CORS.
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:9200/. This can be fixed by moving the resource to the same domain or enabling CORS.
I tried enabling CORS, but get the same error. Here are the index's settings:
{
"portal": {
"settings": {
"index": {
"creation_date": "1421788614558",
"uuid": "jg-iHjnSTDGHODY0_x4Ysw",
"number_of_replicas": "1",
"http": {
"cors": {
"enabled": "true",
"allow-origin": "/(http://)?localhost(:[0-9]+)?/"
}
},
"number_of_shards": "5",
"version": {
"created": "1040299"
}
}
}
}
}

Add following line to your config yml file
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
http.cors.allow-credentials: true
and kill elastic search java process on unix based system like is demonstrated on this topic response https://stackoverflow.com/a/41644614/11079315

I don't know why you are getting a cross domain error to begin with. Are you opening your front end as file://.... ? Totally random guess and not sure it matters. If you are and want to run your UI through a web server, you can open a terminal, cd into that dir and run 'python -m SimpleHTTPServer 7000'. Now your UI is running on localhost:7000.
For CORS settings, see http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-http.html and, if you are using Chrome, http://www.williamjohnbert.com/2013/06/allow-cors-with-localhost-in-chrome/ might help.
In your config you should at least set 'http.cors.enabled: true' and 'http.cors.allow-credentials: true'. The other defaults should be sensible. You may also want to modify the 'http.cors.max-age' setting in case old settings are cached.
Use the js console, net tab in your browser to see what headers you are getting back.
