HttpPut请求什么都不发送（Android）

Question

我试图从网络服务中提取json数据。我使用HttpPut请求但没有任何反应，我得到了很好的发送价值，我没有错误，我也看不出调试器有什么问题。我也使用了get和delete请求，它们完美地工作...... 我正在将此用于httpPut请求：Http Put Request

这是我的要求：

    public class JSONParser {
     public static void putJSONfromUrl (String url,String idCat, String valueCat) throws JSONException, IOException {
        //--This code works for updating a record from the feed--
        HttpPut httpPut = new HttpPut(url);
        JSONStringer json = new JSONStringer()
                .object()
                .key("idcategorie").value(idCat)
                .key("nomcategorie").value(valueCat)
                .endObject();

        StringEntity entity = new StringEntity(json.toString());
        entity.setContentType("application/json;charset=UTF-8");//text/plain;charset=UTF-8
        entity.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json;charset=UTF-8"));
        httpPut.setEntity(entity);

        // Send request to WCF service
        DefaultHttpClient httpClient = new DefaultHttpClient();

        HttpResponse response = httpClient.execute(httpPut);
        HttpEntity entity1 = response.getEntity();
    }

这就是我调用函数的地方

    @Override
    protected Void doInBackground(String... args) {
        JSONParser jParser = new JSONParser();
        // Getting JSON from URL
        try {
            jParser.putJSONfromUrl(urlComplete, valueId,valueDataText);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (JSONException e) {
            e.printStackTrace();
        }
        return null;
    }
}
