Multipart, probleme d'envoie d'image
Bonjour,
J'ai un souci depuis quelque jours bloqué sur un probleme d’envois d'image (en plus de data formulaire) et je ne comprend pas le probleme...
Je viens donc ici pour que vous m’éclairiez de votre lanterne :O
Donc j'ai une classe Multipart que voici :

Cette classe résulte de plusieurs tuto que j'ai consulté...
Et voici comment je l'utilise :

ArrayList<NameValuePair> toSend = new ArrayList<NameValuePair>();
toSend.add(new BasicNameValuePair("sight_api[lensRight]", name_od_selected));
toSend.add(new BasicNameValuePair("sight_api[lensLeft]", name_og_selected));
MultipartUtils multipart = new MultipartUtils(requestURL, charset, wsse);
multipart.addFormField("sight_api[lensRight]", name_od_selected);
multipart.addFormField("sight_api[lensLeft]", name_og_selected);
multipart.addFilePart("sight_api[file]", uploadFile1);
List<String> response = multipart.finish(); |
Mes arguments se sauvegarde bien sur le serveur mais pas mon image.
Une partie du souci, c'est qu'avec les log Android Studio, je n'arrive pas a voir si j'ai un timeout ou un 200 =>
Code:

05-28 17:25:30.964 23603-23912 D/MultipartUtils﹕ Server returned OK
05-28 17:25:30.964 23603-23912 D/MultipartUtils﹕ message de retour : OK
05-28 17:25:30.964 23603-23912 I/System.out﹕ [CDS]rx timeout:100
05-28 17:25:30.964 23603-23912 I/System.out﹕ [CDS]rx timeout:0 |
Il y a un moment ou j'ai réussit a sauvegardé l'image mais pas les paramètres et maintenant c'est l'inverse...
Voila voilou, si vous voyez d'ou vient mon probleme ou éventuellement si vous avez une autre solution, je suis preneur :s
Je suis dispo pour plus d'information.
