Android- POST multipart form data
Je souhaite envoyer un formulaire en plusieurs parties avec vidéo et données telles que l'e-mail et le nom. Ce qui suit est mon code et cela ne fonctionne pas, il n'y a pas de réponse du serveur
File file =new File(VideoPath);
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("Name", "LDGHT"));
nameValuePairs.add(new BasicNameValuePair("Email", "[email protected]"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
httppost.setEntity(new FileEntity(file, "video/mp4"));
// 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
}

Malheureusement, je n'ai pas réussi à utiliser le code de Venky. Après deux jours, j'ai finalement trouvé ma solution et j'espère qu'elle aidera ceux qui ont le même problème. N'hésitez pas à modifier le code car ce code est basé sur ma structure. Remarque: bitmapProfileImage est une variable globale qui contient une image bitmap (Bitmap bitmapProfileImage;)
public class ContentDownloader {
public static String getHttpPutContent(String url, String token, MultipartEntity multipartEntity) {
try {
HttpClient httpClient = new DefaultHttpClient();
HttpPut put = new HttpPut(url);
put.setHeader("token", token);
// Log.i(TAG, "Token=> " + token);
Log.i(TAG, "Try to open=> " + url);
MultipartEntity reqEntity = multipartEntity;
put.setEntity(reqEntity);
HttpResponse httpResponse = httpClient.execute(put);
int statusCode = httpResponse.getStatusLine().getStatusCode();
Log.i(TAG, "Connection code: " + statusCode);
HttpEntity entity = httpResponse.getEntity();
String serverResponse = EntityUtils.toString(entity);
Log.i(TAG, "Server response=> " + serverResponse);
if(!isStatusOk(statusCode))
return null;
return serverResponse;
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
/**
*
* @param statusCode
* @return True if connection code is 2xx, False otherwise.
*/
private static boolean isStatusOk(int statusCode) {
if((statusCode >= HttpURLConnection.HTTP_OK) && (statusCode <= HttpURLConnection.HTTP_PARTIAL))
return true;
return false;
}
}
Donc, dans votre activité/fragment, vous devriez avoir la classe AsyncTask. Ajoutez le code suivant dans la méthode doInBackground:
@Override
protected Integer doInBackground(Void... params) {
String content = "";
String url = LinkManager.getUserProfileUrl();
Person person = SpStorage.getPersonInfo(context);
String imgPath = SpStorage.getProfilePicPath(context);
String imgName = imgPath.substring(imgPath.lastIndexOf("/") + 1);
if(bitmapProfileImage == null) {
Log.i(TAG, "bitmap is null. Try to get it from profile pic directory...");
String file_path = Environment.getExternalStorageDirectory().getAbsolutePath() +
File.separator + ImageDownloader.DIRECTORY_NAME + File.separator + PROFILE_PICS;
imgPath = new File(file_path, imgName).getAbsolutePath();
bitmapProfileImage = BitmapFactory.decodeFile(imgPath);
}
if(bitmapProfileImage != null) {
Log.i(TAG, "Image address: " + imgPath);
try {
MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("first_name", new StringBody(person.getName()));
reqEntity.addPart("last_name", new StringBody(""));
reqEntity.addPart("email",new StringBody(person.getEmail()));
reqEntity.addPart("birthday", new StringBody(person.getBirthDay()));
reqEntity.addPart("gender", new StringBody(person.getGender(person.getGender())));
reqEntity.addPart("orientation", new StringBody(person.getOrientation(person.getGender(), person.getLookingFor())));
reqEntity.addPart("relationship_status", new StringBody(person.getStatus(person.getStatus())));
reqEntity.addPart("city", new StringBody(person.getCity()));
reqEntity.addPart("about", new StringBody(person.getAboutMe()));
reqEntity.addPart("device_type", new StringBody("Android"));
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmapProfileImage.compress(Bitmap.CompressFormat.PNG, 0, bos);
byte[] data = bos.toByteArray();
ByteArrayBody bab = new ByteArrayBody(data, "profilePic.png");
reqEntity.addPart("photo", bab);
content = ContentDownloader.getHttpPutContent(url, SpStorage.getToken(context), reqEntity);
}
catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
catch (Exception e) {
e.printStackTrace();
}
} else
Log.e(TAG, "Image not found :(");
if(!TextUtils.isEmpty(content)) {
return 0; // registration successful
}
return -1;
}
Enfin, pour utiliser MultipartEntity, vous devez télécharger 4 fichiers jar. L'un est Apache-mime4j et les autres sont httpclient, httpcore et httpmime . Vous devez extraire les fichiers jar et les copier/coller dans ./libs dossier de votre projet.
Il y a ma solution de travail (j'espère plus simple) pour envoyer une image avec un post, en utilisant les bibliothèques Apache http (très important ici est l'ajout de limites Cela ne fonctionnera pas sans cela dans ma connexion). J'espère que cela pourrait aider dans une telle situation:
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] imageBytes = baos.toByteArray();
HttpClient httpclient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(StaticData.AMBAJE_SERVER_URL + StaticData.AMBAJE_ADD_AMBAJ_TO_GROUP);
String boundary = "-------------" + System.currentTimeMillis();
httpPost.setHeader("Content-type", "multipart/form-data; boundary="+boundary);
ByteArrayBody bab = new ByteArrayBody(imageBytes, "pic.png");
StringBody sbOwner = new StringBody(StaticData.loggedUserId, ContentType.TEXT_PLAIN);
StringBody sbGroup = new StringBody("group", ContentType.TEXT_PLAIN);
HttpEntity entity = MultipartEntityBuilder.create()
.setMode(HttpMultipartMode.BROWSER_COMPATIBLE)
.setBoundary(boundary)
.addPart("group", sbGroup)
.addPart("owner", sbOwner)
.addPart("image", bab)
.build();
httpPost.setEntity(entity);
try {
HttpResponse response = httpclient.execute(httpPost);
...then reading response
