HttpURLConnection pour envoyer des fichiers image, audio et vidéo avec le paramètre may (String ou Json String) Android
Je partage la solution pour envoyer une image , fichier audio ou vidéo avec paramètres utilisant HttpURLConnection . Les paramètres peuvent être (chaîne simple ou JSON).
(Client Android à PHP Back end)
Scénario: avoir à télécharger des fichiers multimédias (audio, vidéo et image avec paramètres).
Les fichiers multimédias seront stockés dans un dossier de serveur et les paramètres sur db.
J'ai rencontré un problème: l'image a été téléchargée avec succès tandis que les paramètres manquaient .
Solution potentielle trouvée
Choisir HttpURLConnection au lieu de Httpclient as recommander ici =
Vous vous demandez peut-être quel client est le meilleur?
Le client Apache HTTP a moins de bugs sur Eclair et Froyo. C'est le meilleur choix pour ces versions.
Pour Gingerbread et mieux, HttpURLConnection est le meilleur choix. Son API simple et sa petite taille le rendent idéal pour Android. La compression transparente et la mise en cache des réponses réduisent l'utilisation du réseau, améliorent la vitesse et économisent la batterie. Les nouvelles applications devraient utiliser HttpURLConnection; c'est là que nous dépenserons notre énergie à l'avenir.
Code Android:

byte[] buffer;

if (!sourceFile.isFile()) {
dialog.dismiss();
Log.e("uploadFile", "Source File not exist :" + filepath);
runOnUiThread(new Runnable() {
public void run() {

J'espère que cela t'aides.
Toutes les questions me demandent.
Vous pouvez utiliser Retrofit pour l'appel d'API. Prise en charge minimale de Android est 2,3. Veuillez vérifier les détails.
Vous pouvez le rendre plus simple! Essayez ce qui suit.
public static String uploadImage(Bitmap bitmap, String urlString) {
try {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap = Local.resize(bitmap, 512, 512);
if(filename.toLowerCase().endsWith("jpg") || filename.toLowerCase().endsWith("jpeg"))
bitmap.compress(Bitmap.CompressFormat.JPEG, 70, bos);
if(filename.toLowerCase().endsWith("png"))
bitmap.compress(Bitmap.CompressFormat.PNG, 70, bos);

ContentBody body1 = new StringBody("something");
ContentBody body2 = new StringBody("something");

conn.connect();
