Add parameters to HTTPURL Connection using HTTPPost
URL url = new URL("http://yoururl.com");
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setReadTimeout(10000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("parameter1", parameterValue1));
params.add(new BasicNameValuePair("parameter2", parameterValue2));
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
writer.write(getQuery(params));
writer.flush();
writer.close();
os.close();
conn.connect();
private String getQuery(List<NameValuePair> params) throws
UnsupportedEncodingException
{
StringBuilder result = new StringBuilder();
boolean first = true;
for (NameValuePair pair : params)
{
if (first)
first = false;
else
result.append("&");
result.append(URLEncoder.encode(pair.getName(), "UTF-8"));
result.append("=");
result.append(URLEncoder.encode(pair.getValue(), "UTF-8"));
}
return result.toString();
}

public String makeServiceCall(String url, int method,
List<NameValuePair> params) {
String response = null;
int GET = 1;
int POST = 2;
try {
// http client
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpEntity httpEntity = null;
HttpResponse httpResponse = null;
// Checking http request method type
if (method == POST) {
HttpPost httpPost = new HttpPost(url);
// adding post params
if (params != null) {
httpPost.setEntity(new UrlEncodedFormEntity(params));
}
httpResponse = httpClient.execute(httpPost);
} else if (method == GET) {
// appending params to url
if (params != null) {
String paramString = URLEncodedUtils
.format(params, "utf-8");
url += "?" + paramString;
}
HttpGet httpGet = new HttpGet(url);
httpResponse = httpClient.execute(httpGet);
}
httpEntity = httpResponse.getEntity();
response = EntityUtils.toString(httpEntity);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return response;
}
And you can call this method by using AsyncTask as follow:
try {
JSONObject jData = new JSONObject();
String mParam = "5a325bc1b214c5.50816853";
jData.put("id", mParam);
List<NameValuePair> params1 = new ArrayList<NameValuePair>(2);
params1.add(new BasicNameValuePair("data", jData.toString()));
response = makeServiceCall("http://192.168.1.15:8888/android_login_api/getsPreferiti.php", 1, params1);
} catch (JSONException e) {
e.printStackTrace();
}

Android httpclient login to Rails server

I started to learn about how to make an Android application. I tried to connect my app to rails server by using httpclient, however I cannot understand how to connect between app and the remote server.
Here is part of my code, and I matched id form inside "BasicNameValuePair" with html id values. Please let me know how to check whether login is successful or not.
class SendPost extends AsyncTask<Void, Void, String>
{
protected String doInBackground(Void... unused) {
String content = executeClient();
return content;
}
protected void onPostExecute(String result) {
}
public String executeClient() {
ArrayList<NameValuePair> post = new ArrayList<NameValuePair>();
post.add(new BasicNameValuePair("user_name", "SallyCook"));
post.add(new BasicNameValuePair("user_email", "domain#ppls.kr"));
post.add(new BasicNameValuePair("user_password", "add123456"));
post.add(new BasicNameValuePair("user_password_confirmation", "add123456"));
post.add(new BasicNameValuePair("user_phone", "01013089579"));
HttpClient client = new DefaultHttpClient();
HttpParams params = client.getParams();
System.out.println(params);
HttpConnectionParams.setConnectionTimeout(params, 5000);
HttpConnectionParams.setSoTimeout(params, 5000);
HttpPost httpPost = new HttpPost("http://www.ppls.kr/users/sign_up");
try {
UrlEncodedFormEntity entity = new UrlEncodedFormEntity(post, "UTF-8");
httpPost.setEntity(entity);
HttpResponse responsePost = client.execute(httpPost);
System.out.println(responsePost.getStatusLine());
HttpEntity resEntity=responsePost.getEntity();
if (resEntity != null) {
Log.w("RESPONSE", EntityUtils.toString(resEntity));
}
return EntityUtils.getContentCharSet(entity);
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;

Java application terminates at getOutputStream()

I'm creating an application for our Android devices. The aim of this section is to post a username and password (currently just assigned as a string) to a web service and to receive a login token. When running the code, at the getOutputStream() line, my code terminates and will no progress any further.
I have assigned the android emulator GSM access and also set the proxy and DNS server within Eclipse. I'm not sure where to go with it now!
This is within my onHandleIntent():
protected void onHandleIntent(Intent i) {
try{
HttpURLConnection http_conn = (HttpURLConnection) new URL("http://www.XXXXX.com").openConnection();
http_conn.setRequestMethod("POST");
http_conn.setDoInput(true);
http_conn.setDoOutput(true);
http_conn.setRequestProperty("Content-type", "application/json; charset=utf-8");
String login = URLEncoder.encode("XXXXX", "UTF-8") + "=" + URLEncoder.encode("XX", "UTF-8");
login += "&" + URLEncoder.encode("XXXXX", "UTF-8") + "=" + URLEncoder.encode("XX", "UTF-8");
OutputStreamWriter wr = new OutputStreamWriter(http_conn.getOutputStream());
//TERMINATES HERE
wr.write(login);
wr.flush();
BufferedReader rd = new BufferedReader(new InputStreamReader(http_conn.getInputStream()));
String line = rd.toString();
wr.close();
rd.close();
http_conn.disconnect();
}
catch (IOException e){
}
}
This is my first go at java and have only been writing it for a few days so bear with me if I've missed something obvious.
Thanks

If you want to POST something using HTTP, why not use HTTP POST? ;-)
Here is an example snippet:
public void postData() {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("id", "12345"));
nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
}

This may not be the appropriate answer, but will certainly be helpful to you. I have used this code for sending and receiving the request and reply resp, to a webservice.
This code is working, but will need some Refactoring, as i have used some extra variable, which are not needed.
I have used the NameValuePair here for Post
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();
} /*
* catch (ParserConfigurationException e) { // TODO
* Auto-generated catch block e.printStackTrace(); } catch
* (SAXException e) { // TODO Auto-generated catch block
* 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();
}

String line = rd.toString();
should be
String line = rd.readLine();
that might do the trick. rd.toString() gives you a String representation of your BufferedReader. It does not trigger the HTTP operation. I did not test your code, so there might be other errors as well, this was just the obvious one.

Android, HttpPost for WCF

I'm trying to use httpost to get data from our WCF webservice
If the webservice function is without params , something like List getAllMessages()
I'm getting the List in json, no problem here
The tricky part is when the function needs to get argument
let's say Message getMessage(string id)
when trying to call this kind of functions I get error code 500
The working code is:
public String GetAllTitles()
{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(
"http://www.xxx.com/Service/VsService.svc/GetAllTitles");
httppost.setHeader("Content-Type", "application/json; charset=utf-8");
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
return readHttpResponse(response);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
this code works great for functios without arguments..
I took this code and changed it to:
public String SearchTitle(final String id)
{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(
"http://www.xxx.com/Service/VsService.svc/SearchTitle");
httppost.setHeader("Content-Type", "application/json; charset=utf-8");
httppost.setHeader("Accept", "application/json; charset=utf-8");
NameValuePair data = new BasicNameValuePair("id",id);
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(data);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
return readHttpResponse(response);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
The function header in thr webservice is:
[OperationContract]
public TitleResult SearchTitle(string id)
{
Stopwatch sw = LogHelper.StopwatchInit();
try
{
TitleManager tm = new TitleManager();
Title title = tm.TitleById(id);
sw.StopAndLog("SearchTitle", "id: " + id);
return new TitleResult() { Title = title };
}
catch (Exception ex)
{
sw.StopAndLogException("SearchTitle", ex, "id: " + id);
return new TitleResult() { Message = ex.Message };
}
}
Anyone can see what am I missing?
Thanks, I'm breaking my head over this one.

List isn't json,
try
String data = "{ id : \"" + id + "\" }";
Don't forget to set Content-Length to data.length.
