推荐答案

这是我写的处理只是一个方法。以我为例，我使用JSON为我收到的数据，因为它比XML更加紧凑。我建议使用谷歌的GSON库对象转换为从JSON这样的：

This is a method I wrote for handling just that. In my case I am using JSON for the data that I recieve, because it is much more compact than XML. I suggest using Google's GSON library for converting objects to and from json like that:

Gson gson = new Gson();
JsonReply result = gson.fromJson(jsonResult, JsonReply.class);

在哪里JsonReply仅仅是拿着一些数据的POJO。你可以看到谷歌的有关如何在您的情况下使用GSON Java文档。此外，我必须说，这种方法适用于各种人物。我使用它主要用于sendign西里尔数据。

Where JsonReply is just a pojo for holding some data. You can see Google's java docs about how to use gson in your case. In addition I must say that this method works with all kinds of characters. I am using it mostly for sendign cyrillic data.

public String postAndGetResult(String script, List<NameValuePair> postParameters){
    String returnResult = "";
    BufferedReader in = null;
    try {
        HttpParams httpParameters = new BasicHttpParams();
        HttpProtocolParams.setContentCharset(httpParameters, "UTF-8");
        HttpProtocolParams.setHttpElementCharset(httpParameters, "UTF-8");
        HttpClient client = new DefaultHttpClient(httpParameters);
        client.getParams().setParameter("http.protocol.version",
                HttpVersion.HTTP_1_1);
        client.getParams().setParameter("http.socket.timeout",
                new Integer(2000));
        client.getParams().setParameter("http.protocol.content-charset",
                "UTF-8");
        httpParameters.setBooleanParameter("http.protocol.expect-continue",
                false);
        HttpPost request = new HttpPost(SERVER + script + "?sid="
                + String.valueOf(Math.random()));
        request.getParams().setParameter("http.socket.timeout",
                new Integer(5000));
        UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(
                postParameters, "UTF-8");
        request.setEntity(formEntity);
        HttpResponse response = client.execute(request);
        in = new BufferedReader(new InputStreamReader(response.getEntity()
                .getContent()));
        StringBuffer sb = new StringBuffer("");
        String line = "";
        String NL = System.getProperty("line.separator");
        while ((line = in.readLine()) != null) {
            sb.append(line + NL);
        }
        in.close();
        returnResult = sb.toString();
    } catch (Exception ex) {
        return "";
    } finally {
        if (in != null) {
            try {
                in.close();
            } catch (IOException e) {
            }
        }
    }
    return returnResult;
}

我希望这有助于。
玩得开心：）
