发送HTTP DELETE中的Andr​​oid请求

我的客户的API指定删除对象，DELETE请求必须发送包含描述内容的Json头数据。有效是相同的呼叫如添加一个对象，这是通过POST完成。这工作得很好，我的code胆量是如下：

My client's API specifies that to remove an object, a DELETE request must be sent, containing Json header data describing the content. Effectively it's the same call as adding an object, which is done via POST. This works fine, the guts of my code is below:

HttpURLConnection con = (HttpURLConnection)myurl.openConnection();
con.setRequestMethod("POST");
con.setDoOutput(true);
con.setUseCaches(false);
con.connect();
OutputStreamWriter wr = new OutputStreamWriter(con.getOutputStream());
wr.write(data); // data is the post data to send
wr.flush();

要发送删除请求，我改变了请求方法为删除相应。不过，我得到以下错误：

To send the delete request, I changed the request method to "DELETE" accordingly. However I get the following error:

java.net.ProtocolException: DELETE does not support writing

所以，我的问题是，如何从发送包含Android的头数据DELETE请求？我错过了一点 - 你能头数据添加到DELETE请求？谢谢你。

So, my question is, how do I send a DELETE request containing header data from Android? Am I missing the point - are you able to add header data to a DELETE request? Thanks.
