Elasticsearch provides developers with a set of restful interfaces based on the HTTP protocol, and only needs to construct a rest request and parse the JSON returned by the request for access to the Elasticsearch server. Elasticsearch API interface is rich in functionality, including clustering, monitoring, deployment
