Jersey client API WebResource accept() not setting MIME header correctly?
提问by David Webster
public static WebResource createWebResource()
{
final ClientConfig cc = new DefaultClientConfig();
final Client c = Client.create(cc);
final WebResource wr = c.resource("http://localhost:19801/wtg_inventory_war/wtg/rest")
.path(inv);
return wr;
}
public void tester()
{
final WebResource wr = JaxrsClientUtil.createWebResource()
.path("wtg-service");
wr.accept(MediaType.APPLICATION_XML);
String response = wr.path("get-services")
.type(MediaType.APPLICATION_XML)
.get(String.class);
System.out.println(response);
}
Server side:
服务器端：
@Path("get-services")
@GET
@Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
public Response handleFindInventoryServices(
@Context WtgSpringContainer ioc // Spring config for service operations
)
{
System.out.println("Got a service listing request...");
LOGGER.info("Got a service listing request");
Get the app specific data formatted in JAXB XML or JSON...
.
.
.
return Response.ok(msg).build();
}
Regardless of what the client side sets for acceptable media type, JSON comes back? Using curl with -HAccept:application/json or application/xml works fine. I'd like to test my server with both without changing the server side.
不管客户端为可接受的媒体类型设置了什么，JSON 会回来吗？将 curl 与 -HAccept:application/json 或 application/xml 一起使用可以正常工作。我想在不更改服务器端的情况下测试我的服务器。
Any pointers as to why I cannot force the server to XML as my preferred MIME type?
关于为什么我不能强制服务器将 XML 作为我首选的 MIME 类型的任何指示？

David, I figured it out. You did the same thing I did...
大卫，我想通了。你做的和我做的一样...
WebResource.accept(..)is a static method and is actually returning a WebResource.Builderinstance to you that we were both ignoring, with the correct accept param set on.
WebResource.accept(..)是一个静态方法，实际上返回一个我们都忽略的WebResource.Builder实例，并设置了正确的接受参数。
Once I changed my code from:
一旦我改变了我的代码：
WebResource res = c.resource("http://localhost:5984/");
res.accept(MediaType.APPLICATION_JSON_TYPE);
System.out.println(res.get(String.class));
to:
到：
WebResource res = c.resource("http://localhost:5984/");
Builder builder = res.accept(MediaType.APPLICATION_JSON_TYPE);
System.out.println(builder.get(String.class));
Everything started working, the correct 'Accept' headers got sent to the server.
一切开始工作，正确的“接受”标头被发送到服务器。
Hope that helps.
希望有帮助。

I did run in the same issue as you guys.
我确实和你们遇到了同样的问题。
It works fine with using the accept header property.
使用 accept 标头属性可以正常工作。
An other interessting approach I figured out is to set the content type with the response builder as following:
我想出的另一种有趣的方法是使用响应构建器设置内容类型，如下所示：
return Response.status(Status.OK).entity(dto).type(request.getContentType()).build();
If you do that you can use both the acceptand the content-typeproperty.
如果这样做，您可以同时使用accept和content-type属性。
