How to display Java HttpPost object as a string?

Question

I am creating an HttpPost object in Android to communicate with a server that the client is managing. Unfortunately, the server does not provide any of us with very useful error messages; I would like to see the contents of the HttpPost object as a string so that I can send it to our client, and it can compare it with what it expects.

How to convert an HttpPost object to a string that reflects what it will look like when it arrives at the server?

Answer 1

I usually send a message (server response is a JSON object):

  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()); } } 

And postData:

 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; } 

Hope this helps

Well, I really used HTTP-Post with NameValuePair ... I show the code that I use for HTTP-Post , and then converting Response to String

See the method code below:

 public String postData(String url, String xmlQuery) { final String urlStr = url; final String xmlStr = xmlQuery; final StringBuilder sb = new StringBuilder(); Thread t1 = new Thread(new Runnable() { public void run() { HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost(urlStr); try { List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1); nameValuePairs.add(new BasicNameValuePair("xml", xmlStr)); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); HttpResponse response = httpclient.execute(httppost); Log.d("Vivek", response.toString()); HttpEntity entity = response.getEntity(); InputStream i = entity.getContent(); Log.d("Vivek", i.toString()); InputStreamReader isr = new InputStreamReader(i); BufferedReader br = new BufferedReader(isr); String s = null; while ((s = br.readLine()) != null) { Log.d("YumZing", s); sb.append(s); } Log.d("Check Now",sb+""); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } }); t1.start(); try { t1.join(); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println("Getting from Post Data Method "+sb.toString()); return sb.toString(); }

Must use it after execution

 public static String httpPostToString(HttpPost httppost) { StringBuilder sb = new StringBuilder(); sb.append("\nRequestLine:"); sb.append(httppost.getRequestLine().toString()); int i = 0; for(Header header : httppost.getAllHeaders()){ if(i == 0){ sb.append("\nHeader:"); } i++; for(HeaderElement element : header.getElements()){ for(NameValuePair nvp :element.getParameters()){ sb.append(nvp.getName()); sb.append("="); sb.append(nvp.getValue()); sb.append(";"); } } } HttpEntity entity = httppost.getEntity(); String content = ""; if(entity != null){ try { content = IOUtils.toString(entity.getContent()); } catch (Exception e) { e.printStackTrace(); } } sb.append("\nContent:"); sb.append(content); return sb.toString(); }
