I'm making an http connection using following code:
HttpClient client = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpResponse response = client.execute(httpPost);
I want to read a bytearray from the response object.
How would I do that?
You can read the byte array directly with the method: EntityUtils.toByteArray
Example
HttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet("localhost:8080/myurl");
HttpResponse response = client.execute(get);
byte[] content = EntityUtils.toByteArray(response.getEntity());
You can use:
HttpResponse response = client.execute(httpPost);
String content = EntityUtils.toString(response.getEntity());
byte[] bytes = content.getBytes("UTF8");
You can replace the character encoding with one appropriate for the response.
I did something very similar to this, but it was a while ago.
Looking at my source code I used
HttpClient client = new DefaultHttpClient();
String url = "http://192.168.1.69:8888/sdroidmarshal";
HttpGet getRequest = new HttpGet(url);
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String proto = client.execute(getRequest, responseHandler);
I'm pretty certain that the ResponseHandler is the key to this. My get request simply returned something I needed as a string, which was quite simple.
In the case of a bytearray you'll probably want to use an InputStream like so
ResponseHandler<InputStream> responseHandler = new BasicResponseHandler();
InputStream in = client.execute(getRequest, responseHandler);
After which just handle the InputStream as normal.
A bit of googling suggested you may also need to use HttpResponseHandler() rather than BasicResponseHandler() as in my example, I'd fiddle.
The full source code of my work is here, it might be helpful for you.
Kotlin Way
run this on async task on background thread otherwise it will through the error that network task is running on main thread
doAsync {
val client: HttpClient = DefaultHttpClient()
val get = HttpPost("*your url*")
get.setHeader("Authorization","Bearer "+Utils.token)
val response: HttpResponse = client.execute(get)
val content = EntityUtils.toByteArray(response.getEntity())
onComplete {
createPdf(content)
}
}

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.

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);
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.

I've been trying this for the best part of two weeks now, and I am really stuck. Initially I had created a simple ObjectOutputStream client - server program - with the client being the Android app, but it does not work (it reads the connection but not the object).
So now I am confused as to what other approaches I might be able to take to carry out this simple task? Can anyone Help?
have you tried URLConnection using post method? :)
Or get method like:
String yourURL = "www.yourwebserver.com?value1=one&value2=two";
URL url = new URL(yourURL);
URLConnection connection = url.openConnection();
BufferedReader in = new BufferedReader(
new InputStreamReader(connection.getInputStream()));
response = in.readLine();
you can try JSON stirng to send data. We have a lot of stuff available on how to work with JSON and also there are many api's. JSONSimple is the one I can suggest. Its really easy.
why don't you try this:
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
You can use this to post an Entity to server:
HttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost(url);
postRequest.setEntity(entity);
try {
HttpResponse response = httpClient.execute(postRequest
);
String jsonString = EntityUtils.toString(response
.getEntity());
Log.v(ProgramConstants.TAG, "after uploading file "
+ jsonString);
return jsonString;
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
An Entity can be name value pair:
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
nvps.add(new BasicNameValuePair("key1", value1));
nvps.add(new BasicNameValuePair("key2", value2));
Entity entity=new UrlEncodedFormEntity(nvps, HTTP.UTF_8)
Or you can send an entity with bytearray.
Bitmap bitmapOrg=getBitmapResource();
ByteArrayOutputStream bao = new ByteArrayOutputStream();
bitmapOrg.compress(Bitmap.CompressFormat.JPEG, 90, bao);
byte[] data = bao.toByteArray();
MultipartEntity entity=new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE)
entity.addPart("file", new ByteArrayBody(data, "image/jpeg",
"file"));
If you want to post json to server:
Please check out this link How do I send JSon as BODY In a POST request to server from an Android application?
For serializing and deserializing java object, I recommend https://sites.google.com/site/gson/gson-user-guide#TOC-Using-Gson
Really hope it can help you see an overview of sending data to server
I want to download a file and need to check the response status code (ie HTTP /1.1 200 OK).
This is a snipped of my code:
HttpGet httpRequest = new HttpGet(myUri);
HttpEntity httpEntity = null;
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response = httpclient.execute(httpRequest);
...
How do i get the status-code of the response?
This will return the int value:
response.getStatusLine().getStatusCode()
if (response.getStatusLine().getStatusCode()== HttpsURLConnection.HTTP_OK){
...
}
Use code() function of response to get its HTTP code:
val code = response.code()
