如何解析 javax.ws.rs.core.Response

Question

I am having trouble understanding how to parse javax.ws.rs.core.Response. Some people have pointed to using an InputStream, but I am not understanding how that works since the return type of response.getEntity() is of type Object. For example:

Response response = client.target(enpoint).request(MediaType.APPLICATION_XML).get();
InputStream is = response.getEntity();

NetBeans complains and says I will need to cast type Object to InputStream. The response is going to consist of XML and I just want to be able to parse it with DOM. I am having trouble getting from javax.ws.rs.core.Response to anything useful.

Any ideas?

Answer 1

For JAX-RS 2.x Client API, use Response.readEntity(InputStream.class) . Alternatively, is you don't need any specific information from the Response object, you can simple do

InputStream is = client.target(enpoint).request(
                            MediaType.APPLICATION_XML).get(InputStream.class);

Answer 2

也有效：

MyResponse myResponse = response.readEntity(MyResponse.class);

Answer 3

InputStream responseBody = (InputStream) response.getEntity();
