如何将Java HttpPost对象显示为字符串？

Question

我正在HttpPostAndroid中创建一个对象,以便与客户端运行的服务器进行通信.不幸的是,服务器没有向我们提供非常有用的错误消息; 我希望将HttpPost对象的内容看作一个字符串,这样我就可以将它发送给我们的客户端,他可以将它与他期望的内容进行比较.

如何将HttpPost对象转换为一个字符串,反映它到达服务器时的外观？

我通常以这种方式发布（服务器答案是一个 JSON 对象）：

    try {
        postJSON.put("param1", param1);
        postJSON.put("param2",param2);

    } catch (JSONException e) {
        e.printStackTrace();
    }

    String result = JSONGetHTTP.postData(url);
    if (result != null) {
        try {

            JSONObject jObjec = new JSONObject(result);

            }
        } catch (JSONException e) {
            Log.e(TAG, "Error setting data " + e.toString());
        }
    }

postData 是：

public static String postData(String url, JSONObject obj) {
    // Create a new HttpClient and Post Header
    HttpClient httpclient = null;
    try {
        HttpParams myParams = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(myParams, 30000);
        HttpConnectionParams.setSoTimeout(myParams, 30000);
        httpclient = new DefaultHttpClient(myParams);

    } catch (Exception e) {
        Log.e("POST_DATA", "error in httpConnection");
        e.printStackTrace();
    }

    InputStream is = null;
    try {
        HttpPost httppost = new HttpPost(url.toString());
        //Header here   httppost.setHeader();
        StringEntity se = new StringEntity(obj.toString());

        httppost.setEntity(se);

        HttpResponse response = httpclient.execute(httppost);

        HttpEntity entity = response.getEntity();
        // // Do something with response...
        is = entity.getContent();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    // convert response to string
    BufferedReader reader = null;
    String result = null;
    try {
        reader = new BufferedReader(new InputStreamReader(is, "UTF-8"), 8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }

        result = sb.toString();

    } catch (Exception e) {
        Log.e("log_tag", "Error converting result " + e.toString());
    } finally {

        try {
            if (reader != null)
                reader.close();
            if (is != null)
                is.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

    if (result != null) {
        try {
            @SuppressWarnings("unused")
            JSONObject jObjec = new JSONObject(result);

        } catch (JSONException e) {
            Log.e("log_tag", "Error parsing data " + e.toString());
        }
    }

    return result;
}
