How to retrieve JSON Response from a javax.ws.rs.core.Response response?

Question

I am making a request to an API and getting a response status code of 200.

Response of the api includes a json response.

import javax.ws.rs.core.Response;

Response response = webclient.post(SomeReqString);

How can I retrieve the json response as string from the web client response?

Answer 1

You can use following code

String responseAsString = response.readEntity(String.class);

I tried this. The response object doesn't have a method called readEntity() – Harmonica

I don't know if it is deprecated by now. It at least had it once. docs.oracle.com/javaee/7/api/javax/ws/rs/core/… – Irmgardirmina

Answer 2

Try using the Response.getEntity() method, which returns an InputStream. Then, to convert your InputStream to a String, check this question. If you really need to map the JSON String to a Java entity, that consider calling directly the Response.readEntity(). Note that, if you consume the InputStream, you will probably have to process the input stream on your own.

For me the getEntity() method is always returning null. I had to use readEntity(). (javax.ws.rs.core.Response from JavaEE 7). – Bersagliere

Answer 3

You could try

String responseAsString = response.getEntity().toString();
