Télécharger le fichier par HTTP POST

Je veux télécharger un fichier (une image en particulier) à un REPOS Serveur à l'aide de HTTP POST. J'ai déjà importé/ajouter à construire chemin httpmime-4.3.1.jar et apache-mime4j-0.6.jar. Et je suis le suivi des erreurs ci-dessous dans la Trace de la Pile.

Est-ce valable? post.setHeader("enctype", "multipart/form-data");

HTTP POST Code

public void multiPartPost() throws ClientProtocolException, IOException {
    File image = new File(EXTERNALSTORAGE + "/Pictures/sample.jpg");
    FileBody fileBody = new FileBody(image);

    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost(url);
    post.setHeader("enctype", "multipart/form-data");

    MultipartEntityBuilder multipartEntity = MultipartEntityBuilder.create();
    multipartEntity.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
    multipartEntity.addPart("sampleImage", fileBody);
    post.setEntity(multipartEntity.build());

    HttpResponse response = client.execute(post);
    String responseBody = EntityUtils.toString(response.getEntity());
    Log.v("multiPartPost HTTP Response", responseBody);
}

Vous semblent manquer une dépendance.

J'ai httpclient-4.2.5, httpcleint-cache-4.2.5, httpcore-4.2.4 et httpmime-4.2.5 avec commons-lang3-3.1 et commons-logging-1.1.2 pots dans mon chemin de classe.

J'utilise aussi entity.addPart(formFieldName, new FileBody(file, "image/jpeg")); au lieu d'utiliser l'en-tête de la propriété.

Prendre un coup d'oeil à Internet type de média pour plus de détails

Fonctionne parfaitement maintenant, merci!
Que fait un changement agréable 😉
Aussi, la raison pour laquelle j'ai été en utilisant setHeader était parce que lors du téléchargement vers le RESTE du serveur, il ne serait pas le mettre dans le FILES dossier. Et semble-t-il enctype=multipart/form-data le fait. Serais-je capable d'utiliser enctype=multipart/form-data comme deuxième paramètre de FileBody?
Ne sais pas, donnez-lui de l'essayer. Rappelez-vous, si c'est déjà au travail, alors vous pourriez avoir besoin d'elle. Il était le seul (important) différences que j'ai pu voir entre votre code et mon code 😉
Merci de ne pas modifier les réponses, il les ruines qu'il ne cesse entre la question et accostée plus récent, au lieu de cela, laisser des commentaires qui mettent en évidence les changements de l'API, en indiquant la version de la modification a eu lieu, comme tout le monde ne sera en utilisant la même version...
