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?

Solution 1

You can use following code

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

Solution 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.
