passing json data in elasticsearch get request using rest-client ruby gem

elasticsearch, rest-client, ruby

Solution

RestClient can't send request bodies with `GET`. You've got two options:

Pass your query as the `source` URL parameter:

require 'rest_client'
require 'json'

# RestClient.log=STDOUT # Optionally turn on logging

q = '{
    "query" : { "term" : { "user" : "kimchy" } }
}
'
r = JSON.parse \
      RestClient.get( 'http://localhost:9200/twitter/tweet/_search',
                      params: { source: q } )

puts r

...or just use `POST`.

UPDATE: Fixed incorrect passing of the URL parameter, notice the `params` Hash.

Problem

How do I execute the below query(given in doc) using rest client. ``` curl -XGET 'http://localhost:9200/twitter/tweet/_search' -d '{ "query" : { "term" : { "user" : "kimchy" } } } ' ``` I tried doing this: ``` q = '{ "query" : { "term" : { "user" : "kimchy" } } } ' r = JSON.parse(RestClient.get('http://localhost:9200/twitter/tweet/_search', q)) ``` This threw up an error: ``` in `process_url_params': undefined method `delete_if' for #<String:0x8b12e18> (NoMethodError) from /home/socialapps/.rvm/gems/ruby-1.9.3-p194/gems/rest-client-1.6.7/lib/restclient/request.rb:40:in `initialize' from /home/socialapps/.rvm/gems/ruby-1.9.3-p194/gems/rest-client-1.6.7/lib/restclient/request.rb:33:in `new' from /home/socialapps/.rvm/gems/ruby-1.9.3-p194/gems/rest-client-1.6.7/lib/restclient/request.rb:33:in `execute' from /home/socialapps/.rvm/gems/ruby-1.9.3-p194/gems/rest-client-1.6.7/lib/restclient.rb:68:in `get' from get_check2.rb:12:in `<main>' ``` When I do the same using `RestClient.post`, it gives me the right results!. But the elasticsearch doc uses `XGET` in curl command for the search query and not `XPOST`. How do I get the `RestClient.get` method to work? If there are alternate/better ways of doing this action, please suggest.
