How to Parse javax.ws.rs.core.Response
提问by Geoff Penny
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:
我无法理解如何解析 javax.ws.rs.core.Response。有些人指出使用 InputStream，但我不明白它是如何工作的，因为 response.getEntity() 的返回类型是 Object 类型。例如：
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.
NetBeans 抱怨并说我需要将类型 Object 强制转换为 InputStream。响应将由 XML 组成，我只想能够用 DOM 解析它。我无法从 javax.ws.rs.core.Response 获取任何有用的信息。
Any ideas?
有任何想法吗？

For JAX-RS 2.x Client API, use Response.readEntity(InputStream.class). Alternatively, is you don't need any specific information from the Responseobject, you can simple do
对于 JAX-RS 2.x 客户端 API，请使用Response.readEntity(InputStream.class). 或者，您是否不需要来自Response对象的任何特定信息，您可以简单地做
InputStream is = client.target(enpoint).request(
MediaType.APPLICATION_XML).get(InputStream.class);

Also works:
也有效：
MyResponse myResponse = response.readEntity(MyResponse.class);
