Get the XML entity passed in body - HTTP Put method in Android

I wanted to retrieve the XML entity passed in body of HTTP Put method. I used the below code,
DefaultHttpServerConnection conn = new DefaultHttpServerConnection();
conn.bind(serverSocket.accept(), new BasicHttpParams());
HttpRequest request = conn.receiveRequestHeader();
conn.receiveRequestEntity((HttpEntityEnclosingRequest)request);
HttpEntity entity = ((HttpEntityEnclosingRequest)request).getEntity();
System.out.println(EntityUtils.toString(entity));
I could get the norma strings, but when trying to pass the XML entity, I could not even see the print statement.

I hope this code help you.
HttpPost httppost = new HttpPost(SERVICE_EPR);
StringEntity se = new StringEntity(SOAPRequestXML,HTTP.UTF_8);
se.setContentType("text/xml");
httppost.setHeader("Content-Type","application/soap+xml;charset=UTF-8");
httppost.setEntity(se);
HttpClient httpclient = new DefaultHttpClient();
BasicHttpResponse httpResponse =
(BasicHttpResponse) httpclient.execute(httppost);
response.put("HTTPStatus",httpResponse.getStatusLine().toString());

PFB the solution,
DefaultHttpServerConnection conn = new DefaultHttpServerConnection();
params = new BasicHttpParams();
conn.bind(socket, params);
//Extracting the information from the requested URI
HttpRequest request = conn.receiveRequestHeader();
conn.receiveRequestEntity((HttpEntityEnclosingRequest)request);
HttpEntity httpEntity = ((HttpEntityEnclosingRequest)request).getEntity();
if(httpEntity != null){
InputStream instream = httpEntity.getContent();
try {
// do something useful
String myString = IOUtils.toString(instream, "UTF-8");
Log.e(TAG,">>>> http body > "+myString);
} finally {
instream.close();
}
}
Don't put any log or print statements using the data you received, I was getting 'Content already consumed' exception. I had used several logs using the httpEntity i received and that was causing the problem for me. I commented those(marked yellow) and started working.

HttpContext not holding cookies

I'm trying to use cookies to hold my session on my Android app, but it seems I'm getting something wrong, because I never receive the expected response from my server.
At first I have a login routine that runs as expected and return all expected data.
My login request:
HttpContext httpContext = new BasicHttpContext();
HttpResponse response;
HttpClient client = new DefaultHttpClient();
String url = context.getString(R.string.url_login);
HttpPost connection = new HttpPost(url);
connection.setHeader("Content-Type","application/x-www-form-urlencoded");
List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2);
nameValuePair.add(new BasicNameValuePair(PARAM_LOGIN,params[0]));
nameValuePair.add(new BasicNameValuePair(PARAM_PASSWORD,params[1]));
connection.setEntity(new UrlEncodedFormEntity(nameValuePair,"UTF-8"));
response = client.execute(connection,httpContext);
data = EntityUtils.toString(response.getEntity());
After I've my response I just make what ever I need with the data and then things start to fall a part. Because now I'm just trying to call my server in the same AsyncTask to test if my cookies got properly saved on my HttpContext.
At first I've just called my URL without any change, just reusing my current HttpContext:
HttpPost httpPost = new HttpPost(context.getString(R.string.url_cookie_test));
HttpResponse response = client.execute(httpPost, httpContext);
Since this test fails I tested to add my cookie value on my HttpPost header:
httpPost.addHeader(context.getString(R.string.domain),PHPSESSID+"="+cookieID+";");
Then I tried creating a new HttpContext and force the COOKIE_STORE:
CookieStore cookieStore = new BasicCookieStore();
BasicClientCookie cookie = new BasicClientCookie(PHPSESSID, cookieID);
cookieStore.addCookie(cookie);
HttpContext localContext = new BasicHttpContext();
localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
HttpResponse response;
HttpClient client = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(context.getString(R.string.url_cookie_test));
response = client.execute(connection,localContext);
All fails, and I've already confirmed that when I first receive my login response I got the data expected from the cookies as can see below:
List<Cookie> cookies = ((AbstractHttpClient) client).getCookieStore().getCookies();
for (Cookie cookie: cookies){
Log.i("Cookie Value",cookie.toString());
/*
Prints:[[version: 0][name: PHPSESSID][value: 2ebbr87lsd9077m79n842hdgl3][domain: mydomain.org][path: /][expiry: null]]
*/
}
I've already searched on StackOverflow and I've found a ton of solutions that doesn't really worked for me, will share all solutions I've already tried:
Android: Using Cookies in HTTP Post request
HttpPost request with cookies
Sending cookie with http post android
Apache HttpClient 4.0.3 - how do I set cookie with sessionID for POST request

As I told you, here you are this piece of code in order to make httpPost to a server developed in Spring MVC, with an API REST. Please, consider to build your request on this way:
Please, pay attention to the comments. You should adapt it to your case ;). You can also enclose this code into a method or whatever you prefer.
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("yourPath");
//NameValuePairs is build with the params for your request
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
httppost.setHeader("Content-Type",
"application/x-www-form-urlencoded");
CookieStore cookieStore = new BasicCookieStore();
//cookie is a variable that I stored in my shared preferences.
//You have to send in it every request
//In your case, JSESSIONID should change, because it's for Java.
//Maybe it could be "PHPSESSID"
BasicClientCookie c = new BasicClientCookie("JSESSIONID", cookie);
//JSESSIONID: same comment as before.
httppost.setHeader("Cookie", "JSESSIONID="+cookie);
cookieStore.addCookie(c);
((AbstractHttpClient)httpclient).setCookieStore(cookieStore);
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
} catch (Exception e) {
Log.e("log_tag", "Error in http connection" + e.toString());
}
I hope this helps!! It was hard to find it among "old" projects :)

Android:Trying to make an httpPost Request but keep getting connection timeout

I am really in pain right now please help me solve this issue.
I've previously also tried to make the http request to my localhost and it all works fine but right now it is not working and I don't know why.
I am trying to make the request from the following code.
HttpClient httpclient = new DefaultHttpClient();
String result="";
try
{
HttpPost httppost = new HttpPost("http://[ip]/php/untitled.php");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
nameValuePairs.add(new BasicNameValuePair("email",this.userEmail));
nameValuePairs.add(new BasicNameValuePair("pwd",this.userpassword));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity=response.getEntity();
if(entity!=null)
{
InputStream inputStream=entity.getContent();
result= convertStreamToString(inputStream);
}
}
catch (ClientProtocolException e)
{
Log.e("errorhai",e.getMessage());
}
catch (IOException e)
{
Log.e("errorhai",e.getMessage());
}
return result;
I've also added the internet permission but still it keeps saying
Connect to [ip] timed out.
When I enter the url in my browser it works fine but it is not working here.Please tell me what can be the causes of this problem ?

you can set the time out parameter to handle such type of exception :
HttpParams httpParameters = new BasicHttpParams();
/* Set the timeout in milliseconds until a connection is established.
The default value is zero, that means the timeout is not used.*/
int timeoutConnection = 60*1000*1;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
/* Set the default socket timeout (SO_TIMEOUT)
in milliseconds which is the timeout for waiting for data. */
int timeoutSocket = 60*1000*1;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
HttpClient client = new DefaultHttpClient(httpParameters);
//HttpClient client = new DefaultHttpClient();
HttpResponse httpResponse;
try {
/** Finally, we send our request using HTTP. This is the synchronous
long operation that we need to run on this thread. */
httpResponse = client.execute(request);
/*int responseCode = httpResponse.getStatusLine().getStatusCode();
String message = httpResponse.getStatusLine().getReasonPhrase();*/
HttpEntity entity = httpResponse.getEntity();
if (entity != null) {
InputStream instream = entity.getContent();
String res = convertStreamToString(instream);
MLog.v("HTTP RESPONSE : ", "Res :-"+res);
if(!res.trim().equalsIgnoreCase("[]")){
response.setResult(res);
response.setSuccess(true);
}else{
response.setSuccess(false);
response.setErrorMessage(AppConstant.RECORD_NOT_FOUND);
}
/** Closing the input stream will trigger connection release */
instream.close();
}else{
response.setSuccess(false);
response.setErrorMessage(AppConstant.NETWORK_ERROR);
}
}
catch (Exception e) {
//client.getConnectionManager().shutdown();
e.printStackTrace();
response.setSuccess(false);
response.setErrorMessage(AppConstant.NETWORK_ERROR);
}
//you can again try to send request , if your response is not sucess.
//retryHttpRequestIfNotSucess();

your problem might be related to the login. Is your script expecting a preemptive authetification? Do you have a error page for a failed login?
For requesting a page with preemptive http basic authentication i'm using the following code that is working. Have a try, if its working for you too.
DefaultHttpClient httpclient = null;
HttpParams params = new BasicHttpParams();
HttpResponse response = null;
HttpEntity entity = null;
// Set connection parameter
params.setParameter(HttpProtocolParams.USE_EXPECT_CONTINUE, false);
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
httpclient = new DefaultHttpClient(params);
// Create a post statement
HttpPost httppost = new HttpPost(Constants.urlLogin);
httppost.getParams().setParameter(ClientPNames.COOKIE_POLICY, CookiePolicy.RFC_2965);
httppost.getParams().setParameter("http.protocol.single-cookie-header", true);
httppost.getParams().setParameter(ClientPNames.COOKIE_POLICY, CookiePolicy.BROWSER_COMPATIBILITY);
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
nvps.add(new BasicNameValuePair("login_name", this.username));
nvps.add(new BasicNameValuePair("login_passwd", this.userpassword));
httppost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
response = httpclient.execute(httppost);
entity = response.getEntity();
int statusCode = response.getStatusLine().getStatusCode();
String loadedContent = null;
if (entity != null)
{
loadedContent = EntityUtils.toString(entity, HTTP.UTF_8);
// loadedContent =
// Helper.convertStreamToString(entity.getContent());
entity.consumeContent();
}
if (statusCode != (HttpStatus.SC_OK))
{
throw new ServerCommunicationErrorException();
} else if (!loadedContent.contains("Logout"))
{
// Login failed
throw new LoginFailedException();
}
As you can see, i get a "not logged in" page as result, if the login fails to determine the login process. Further more i set some parameters, that might be also interesting for you. You can look here for more information on parameters.

Sending Video using HTTP Post Multipart entity

What I want I want to send a video from my SDcard to a server. I also want to send some parameters/value with it.
I have tried I have tried the following code:
public String SendToServer(String aUrl,File aFile)
{
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(aUrl);
try
{
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
entity.addPart("file", new FileBody(aFile));
entity.addPart("video[title]", new StringBody("testVideo"));
entity.addPart("video[type]", new StringBody("1"));
httpPost.setEntity(entity);
HttpContext localContext = new BasicHttpContext();
// Bind custom cookie store to the local context
localContext.setAttribute(ClientContext.COOKIE_STORE, Globals.sessionCookie);
HttpResponse response = httpClient.execute(httpPost, localContext);
HttpEntity resEntity = response.getEntity();
String Response = "";
if (response != null)
{
Response = EntityUtils.toString(resEntity);
}
return Response;
}
catch (IOException e)
{
e.printStackTrace();
}
return "Exception";
}
What is the problem When I run this code, I get stuck at this line
HttpResponse response = httpClient.execute(httpPost, localContext);
I get no exception, no response nothing at all. Can anyone please guide me, what is the problem in here?

The above code in my question was perfect, but I had the network problem. My device was connected to a hotspot(Connectify Software). When I connected to the original network, this code worked perfect.
I recommend you people to never trust a hotspot for this kind of functionality.

try using this way if want to send as content or esle I will upload the project by tonight
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
InputStreamEntity reqEntity = new InputStreamEntity(new FileInputStream(filePath), -1);
reqEntity.setContentType("binary/octet-stream");
reqEntity.setChunked(true); // Send in multiple parts if needed
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);

NTLM authentication in Android app

I'm using JCIFS library found here to use NTLM authentication in my android app.The app worked fine when it just went to a site and parsed an xml, but now that I added the NTLM auth it doesn't seem to be working. Can anyone tell from this snippet of code if where the problem is between the httpclient and the inputstream?
DefaultHttpClient client = new DefaultHttpClient();
client.getAuthSchemes().register("ntlm", new NTLMSchemeFactory());
client.getCredentialsProvider().setCredentials(new AuthScope("http://www.musowls.org",80),
new NTCredentials(username, password, null, "musschool"));
HttpGet request = new HttpGet("http://www.musowls.org/assignments/assignmentsbystudentxml.aspx");
HttpResponse resp = client.execute(request);
HttpEntity entity = resp.getEntity();
InputStream inputStream = entity.getContent();

Try below code it may be help you.
DefaultHttpClient httpclient = new DefaultHttpClient();
httpclient.getAuthSchemes().register("ntlm", new NTLMSchemeFactory());
NTCredentials creds = new NTCredentials("user_name", "password", "", "http://www.musowls.org/");
httpclient.getCredentialsProvider().setCredentials(AuthScope.ANY, creds);
HttpConnectionParams.setConnectionTimeout(httpclient.getParams(), 5000);
HttpPost httppost = new HttpPost("http://www.musowls.org/assignments/assignmentsbystudentxml.aspx");
httppost.getParams().setBooleanParameter(CoreProtocolPNames.USE_EXPECT_CONTINUE, false);
HttpResponse response = httpclient.execute(httppost); // ERROR HAPPENS HERE
responseXML = EntityUtils.toString(response.getEntity());
Log.d("Responce", responseXML);

1) Download JCIFS from here: http://jcifs.samba.org/
2) Follow the instructions here: http://hc.apache.org/httpcomponents-client-ga/ntlm.html

Been stuck on this problem for way too long.
Check out the answer in this thread to use OkHttp3 for NTLM Authenticated calls:
