Upload image to Spring Server API in Android

i'm traying to upload a image in Android App to my api, but i have this menssage:
"The current request is not a multipart request"
I've this code in my app android:
#Override
protected String doInBackground(String... uri) {
// url where the data will be posted
String postReceiverUrl = "http://...";
Log.v("TEST", "postURL: " + postReceiverUrl);
// HttpClient
HttpClient httpClient = new DefaultHttpClient();
// post header
HttpPost httpPost = new HttpPost(postReceiverUrl);
try {
// the URL where the file will be posted
File file = new File(mCurrentPhotoPath);
FileBody fileBody = new FileBody(file);
MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("file", fileBody);
httpPost.setEntity(reqEntity);
// execute HTTP post request
HttpResponse response = httpClient.execute(httpPost);
HttpEntity resEntity = response.getEntity();
if (resEntity != null) {
String responseStr = EntityUtils.toString(resEntity).trim();
Log.v("TEST ", "Response: " + responseStr);
// you can add an if statement here and do other actions based on the response
}
} catch (Exception e) {
e.printStackTrace();
}
return "";
}
And in my API i've this code:
#RequestMapping(value = "/upload", method = RequestMethod.POST)
public
#ResponseBody
String handleFileUpload(#RequestParam(value = "file", required = false) MultipartFile file) {
if (!file.isEmpty()) {
try {
byte[] bytes = file.getBytes();
File file1 = new File("test.jpg");
FileOutputStream fos = new FileOutputStream(file1);
BufferedOutputStream stream =
new BufferedOutputStream(fos);
stream.write(bytes);
stream.close();
System.out.println("The path is: ");
System.out.println(file1.getAbsolutePath());
System.out.println(file1.getPath());
return "You successfully uploaded \"test.jpg\"!";
} catch (Exception e) {
return "You failed to upload test.jpg => " + e.getMessage();
}
} else {
return "You failed to upload test.jpg because the file was empty.";
}
}
How can i do this?

May be the following code help to you to upload the image in server
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost(<server api url>);
MultipartEntity entity = new MultipartEntity();
File myFile = new File(<file_path>);
FileBody fileBody = new FileBody(myFile);
entity.addPart("upload_param_name",fileBody);
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost,
localContext);
HttpEntity r_entity = response.getEntity();
xmlString = EntityUtils.toString(r_entity);
Log.d("SOAP ", "Result : " + xmlString.toString());
Also for this, you have to use the .jar of apache-mine and httpmine in your apps libs folder.

Finally i convert the image in base64 and send to server how a String and in my Server reconvert to image.
Thanks!

Android do PATCH/PUT to server

I'm having this issue and I need to put or patch data to the server. I know how to do a standard post, but how can I do this PATCH or PUT to the server?
The URL to the server is PATCH to www.example.com/api/documents and parameter is doc_id(integer).
This is what I currently have
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setHeader("content-type", "application/json");
httpPost.setHeader("accept-charset", "utf8");
try {
HttpResponse response = httpClient.execute(httpPost);
responseString = EntityUtils.toString(response.getEntity());
} catch (Exception e) {
Log.e("Request exception:", "excpetion", e);
}
return responseString;
But this code I think is wrong as hell :)

This is the most common way---
Creating jsonObj and putting json values:
JSONObject jsonObj = new JSONObject();
jsonObj .put("doc_id", <put your value> + "");
String response = callPutService(source, password, callingAPI, jsonObj);
This is the callPutService that is called:
public String callPutService(String userName, String password,
String type, JSONObject jsonObject) {
String line = null, jsonString = "";
HttpResponse response = null;
InputStream inputStream = null;
try {
HttpClient client = new DefaultHttpClient();
HttpConnectionParams.
setConnectionTimeout
(client.getParams(), 20000); // Timeout Limit
HttpPut put = new HttpPut(WEBSERVICE + type);
StringEntity se = new StringEntity(jsonObject.toString());
se.setContentType("application/json;charset=UTF-8");
put.setHeader("Authorization",
"basic " + Base64.
encodeToString((userName + ":" + password).getBytes(),
Base64.URL_SAFE | Base64.NO_WRAP));
put.setEntity(se);
response = client.execute(put);
int responseCode = response.getStatusLine().getStatusCode();
if(responseCode == 200){
//do whatever
}
} catch (Exception e) {
e.printStackTrace();
}
return jsonString;
}

Use arabic text in android

How to get the arabic string in json format and how to display in android application
inputStreamReader. I get the json from server side And using the Windows-1256 encodingString to convert the arabic string but sometext not be shown correctly.
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
System.out.println(url + ":::url");
try {
HttpResponse httpResponse = httpClient.execute(httpGet);
InputStream inputStream = httpResponse.getEntity()
.getContent();
InputStreamReader inputStreamReader = new InputStreamReader(
inputStream,"windows-1256");
//new InputStreamReader(inputStream);
BufferedReader bufferedReader = new BufferedReader(
inputStreamReader,8);
StringBuilder stringBuilder = new StringBuilder();
String bufferedStrChunk = null;
while ((bufferedStrChunk = bufferedReader.readLine()) != null) {
stringBuilder.append(bufferedStrChunk);
}
return stringBuilder.toString();
} catch (ClientProtocolException cpe) {
System.out
.println("Exception generates caz of httpResponse :"
+ cpe);
cpe.printStackTrace();
} catch (IOException ioe) {
System.out
.println("Second exception generates caz of httpResponse :"
+ ioe);
ioe.printStackTrace();
}

I have been r & d around a day and finally success to parse my arabic json response getting from server using following code.So, may be helpful to you.
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, "UTF-8");
params.setBooleanParameter("http.protocol.expect-continue", false);
HttpClient httpclient = new DefaultHttpClient(params);
HttpPost httppost = new HttpPost(Your_URL);
HttpResponse http_response= httpclient.execute(httppost);
HttpEntity entity = http_response.getEntity();
String jsonText = EntityUtils.toString(entity, HTTP.UTF_8);
Log.i("Response", jsonText);
Now, use jsonText for your further requirement.
Thank You

Parse Json Arabic text

I can't parse Arabic/Persian text from SQL database. Everything is set to UTF-8. My SQL database text is set to utf8_general_ci. JSON parser is set to UTF-8 too.
Text is shown good in English. But when I use Arabic/Persian text in database, android shows text as ???????.
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public JSONParser() {
}
// function get json from url
// by making HTTP POST or GET method
public JSONObject makeHttpRequest(String url, String method,
List<NameValuePair> params) {
// Making HTTP request
try {
// check for request method
if(method == "POST"){
// request method is POST
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}else if(method == "GET"){
// request method is GET
DefaultHttpClient httpClient = new DefaultHttpClient();
String paramString = URLEncodedUtils.format(params, "utf-8");
url += "?" + paramString;
HttpGet httpGet = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader 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");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}
}

Thank You

Maybe the problem is on server side. Check the raw String you got from the Server to see if it is correctly formatted.

I think it can help you by storing it as clob/blob, since once you have the bytes which were convereted from UTF-8 at server side, any client side code can also then using various String encoding formats to display the test.
Or my other advice, use a webview to display it, its more mature to handle these nuances.

Send key-value parametres and json message body throught http post request

I need to send http POST request from mobile android application to the server side applcation.
This request need to contain json message in body and some key-value parametres.
I am try to write this method:
public static String makePostRequest(String url, String body, BasicHttpParams params) throws ClientProtocolException, IOException {
Logger.i(HttpClientAndroid.class, "Make post request");
HttpPost httpPost = new HttpPost(url);
StringEntity entity = new StringEntity(body);
httpPost.setParams(params);
httpPost.setEntity(entity);
HttpResponse response = getHttpClient().execute(httpPost);
return handleResponse(response);
}
Here i set parametres to request throught method setParams and set json body throught setEntity.
But it isn't work.
Can anybody help to me?

You can use a NameValuePair to do this..........
Below is the code from my project where I used NameValuePair to sent the xml data and receive the xml response, this will provide u some idea about how to use it with JSON.
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();
}
