I am trying to upload an image to a server along with some JSON data that is collected from a form.

The server has authentication.

METHOD: post HEADERS: Authorization Basic d2Vic2VydmljZTpyM05hdTE3Rw== Content-Type multipart/form-data;boundary=xxxxxxxx BODY: --xxxxxxxx Content-Disposition: form-data; name="jsonFile" Content-Type: application/json {"model":"Premium","deviceLongitude":4.79337638,"pseudo":"nickname","deviceLatitude":45.7671507,"year":"2005","email":"[email protected]","deviceLocale":"fr_FR","title":"my picture"} --xxxxxxxx Content-Disposition: form-data; name="imgName" Content-Type: image/jpeg //Image data array /9j/4AAQSkZJRgABAQAAAQABAAD/4QBYRXhpZgAATU0AKgAAAAgAAgESAAMAAAAB AAEAAIdpAAQAAAABAAAAJgAAAAAAA6ABAAMAAAABAAEAAKACAAQAAAABAAAB4KAD AAQAAAABAAACgAAAAAD/2wBDAAEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEB AQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQH/2wBDAQEBAQEBAQEB AQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEB AQEBAQEBAQH/wAARCAKAAeADAREAAhEBAxEB/8QAHwAAAQUBAQEBAQEAAAAAAAAA AAECAwQFBgcICQoL/8QAtRAAAgEDAwIEAwUFBAQAAAF --xxxxxxxx

The last line should be --xxxxxxxx--, and not --xxxxxxxx.

thanks for the answer it helped me solve my problem. Meanwhile, can you please help me with posting multiple image along with the json. I have posted a question here, please have a look : stackoverflow.com/questions/40279640/…

I know this post is a couple of years old, but I'd like to share my solution using MultiPartEntity from here available as part of the HttpClient download. I used version 4.2.5.

I originally used a process similar to above, which worked well until I started getting memory errors when I started supporting uploading of videos. I researched a lot of posts here and got a lot of good ideas. I used the Java Decompiler available here to look at the code in the Jar file to figure out how to put things together.

//filepath is passed in like /mnt/sdcard/DCIM/100MEDIA/VIDEO0223.mp4 String fileName = filePath.substring(filePath.lastIndexOf("/") + 1); String extension = fileName.substring(fileName.lastIndexOf(".") + 1); String json = "{your_json_goes_here}"; File media = new File(filePath); URI uri = your_uri_goes_here; DefaultHttpClient httpClient = new DefaultHttpClient(); HttpPost post = new HttpPost(uri); StringBody jsonBody = new StringBody(json, "application/json", null); FormBodyPart jsonBodyPart = new FormBodyPart("json", jsonBody); String mimeType; if (requestCode == Constants.ACTION_TAKE_VIDEO) { mimeType = "video/" + extension; } else { // default to picture mimeType = "image/" + extension; } FileBody fileBody = new FileBody(media, mimeType, "ISO-8859-1"); FormBodyPart fileBodyPart = new FormBodyPart(fileName, fileBody); MultipartEntity mpEntity = new MultipartEntity(null, "xxBOUNDARYxx", null); mpEntity.addPart(jsonBodyPart); mpEntity.addPart(fileBodyPart); post.addHeader("Content-Type", "multipart/mixed;boundary=xxBOUNDARYxx"); post.setEntity(mpEntity); HttpResponse response = httpClient.execute(post); InputStream data = response.getEntity().getContent(); BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(data)); String responseLine; StringBuilder responseBuilder = new StringBuilder(); while ((responseLine = bufferedReader.readLine()) != null) { responseBuilder.append(responseLine); } System.out.println("Response: " + responseBuilder.toString());

I'm not specifying the boundary and the content type explicitly. The header is then generated with "multipart/form-data", all parts with their respective content types (in my case json and octet-stream). Did "multipart/mixed" work better for you?

Do not reinvent the wheel! The Apache HttpClient have implemented your requires.

Android JSON HttpClient to send data to PHP server with HttpResponse

Goog luck!

Unless this answer has already be given... I found a neat solution for this same problem. I posted it over here: https://stackoverflow.com/questions/7595939/how-to-upload-multipart-image-data-in-json-request-android/

Try this Code it's easy 

public String postAsync(String url, String action, JSONObject jsonObject, String fileUri) throws JSONException { String result = ""; try { HttpClient httpClient = new DefaultHttpClient(); HttpPost httpPost = new HttpPost(url); MultipartEntityBuilder entityBuilder = MultipartEntityBuilder.create(); entityBuilder.setMode(HttpMultipartMode.STRICT); File file = new File(fileUri); entityBuilder.addPart("file", new FileBody(file)); entityBuilder.addTextBody(DMConstant.ACTION_JSON, action); entityBuilder.addTextBody(DMConstant.DATA_JSON, jsonObject.toString(), ContentType.create("application/json", Consts.UTF_8)); HttpEntity entity = entityBuilder.build(); httpPost.setEntity(entity); HttpResponse httpResponse = httpClient.execute(httpPost); InputStream inputStream = httpResponse.getEntity().getContent(); if (inputStream != null) { result = dmUtils.convertStreamToString(inputStream); } else { Log.i("Input Stream is Null", "Input Stream is Null"); } } catch (UnsupportedEncodingException e) { Log.e("Unsupported Encoding", e.getMessage()); } catch (ClientProtocolException e) { Log.e("Client Protocol", e.getMessage()); } catch (IOException e) { Log.e("IOException", e.getMessage()); } Log.i("JSON Object as Response", result); return result; }

........ JSONObject urlObject = new JSONObject(); urlObject.put("userName", "user name"); urlObject.put("email_id", "ä[email protected]"); urlObject.put("user_pass", "123456"); postAsync(URL, "php function name", urlObject, imageFile);

This is an example to upload image and JSONArray using MultipartEntity-- lib:org.apache.http.entity.mime

List <Entity> students = getStudentList(); MultipartEntity studentList = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); for(int i=0; i<students.size();i++){ try { studentList.addPart("studentList[][name]", new StringBody(String.valueOf(students.get(i).getName()))); studentList.addPart("studentList[][addmission_no]", new StringBody(String.valueOf(students.get(i).getAddmissionNo))); studentList.addPart("studentList[][gender]", new StringBody(String.valueOf(students.get(i).getGender))); File photoImg = new File(students.get(i).getImagePath()); studentList.addPart("studentList[][photo]",new FileBody(photoImg,"image/jpeg")); }catch(Exception e){ e.getMessage(); } } HttpClient client = new DefaultHttpClient(); HttpPost post = new HttpPost(URL); post.addHeader("X-Auth-Token", mUserToken); post.setEntity(studentList); org.apache.http.HttpResponse response = null; try { response = client.execute(post); } catch (IOException e) { e.printStackTrace(); } HttpEntity httpEntity = response.getEntity(); JSONObject myObject; try { String result = EntityUtils.toString(httpEntity); // do your work } catch (IOException e) { e.printStackTrace(); }
