如何在HttpURLConnection中发送PUT，DELETE HTTP请求？

要执行HTTP PUT：

URL url = new URL("http://www.example.com/resource");HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();httpCon.setDoOutput(true);httpCon.setRequestMethod("PUT");OutputStreamWriter out = new OutputStreamWriter(    httpCon.getOutputStream());out.write("Resource content");out.close();httpCon.getInputStream();

要执行HTTP删除：

URL url = new URL("http://www.example.com/resource");HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();httpCon.setDoOutput(true);httpCon.setRequestProperty(    "Content-Type", "application/x-www-form-urlenpred" );httpCon.setRequestMethod("DELETE");httpCon.connect();
