REST Resource Asset: Best way to send data in Request body

#1

Matrix Version: 5.2

So I am looking to construct queries to send to a server to retreive some data. Here is an example of a query that I am looking to use.

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html

I was thinking of using a REST Resource, but it seems like that Matrix doesn’t allow to use “Request Body” with the GET verb.

Is jQuery AJAX my only option? I am looking to avoid it if possible due to cross domain issues. I know JSONP can help, but this will be the last option.

Any help is really appreciated. Thanks

GET requests usually do not have a message body. http://stackoverflow.com/questions/5216567/is-this-statement-correct-http-get-method-always-has-no-message-body

It’s a very uncommon thing to use it seems (first time I’ve come across it).

Does elastic search support passing the data as standard URL GET parameters instead? Or using POST?

Hi Bart, thanks again for your reply. ElasticSearch does support passing data using standard URL GET parameters, but its a very limited subset of what you can send in GET message body.

For example constructing queries like this and this using standard URL GET parameters would be a pain in the back. That is why they recommend sending queries in message body. Their reasoning/advantage maybe is that it allows easily sending XML or JSON request bodies containing complex nested queries, it doesn’t have a length restriction and it’s easier to encode (UTF-8).

Also, upon further investigation, I came across this old document, which states that Elastic does support POST request with message body, if sending a GET request with message body is not feasible. This is for an older version of Elastic, not sure if the latest version (5.1) that I am using also support this. I gotta do some testing …

Cheers …

Thanks for the clarification Paul. Would be interested to know if the POST method is an option, would be surprised if it’s not.
