Websocket input plugin

[Mohamed_eshaftri]

hello,

i need to use Websocket input plugin for indexing json data in to elasticsearch.

this my code in javascript.

<script>
        var ws = new WebSocket(" wss://ws.blockchain.info/inv");
        ws.onopen = function(){
            ws.send(JSON.stringify({"op":"unconfirmed_sub"}))
            console.log('mash')

        };
        ws.onmessage = function(msg){
            var response = JSON.parse(msg.data);
            console.log('response')
        }

    </script>

i am trying to implement the js code in Websocket input plugin, and below my Websocket input plugin config code.

input {
    websocket {
      mode => "client"
      url => "wss://ws.blockchain.info/inv"
      type => "string"
    }
  }

  output {
    elasticsearch {
      hosts => [ "localhost:9200" ]
      index => "calidog"
    }
    stdout { codec => rubydebug }
  }

when i run the config file

[2019-04-13T18:15:16,387][INFO ][logstash.agent           ] Successfully started Logstash API endpoint {:port=>9600}
[2019-04-13T18:15:21,190][INFO ][logstash.runner          ] Logstash shut down.

Thanks
