AFNetworking 3.0 Données de formulaire en plusieurs parties pour télécharger une erreur d'image

Question

J'ai essayé de télécharger une image sur mon serveur AWS en utilisant des données de formulaire multipart afnetworking 3.0 mais apparemment, chaque image que j'ai essayé de télécharger s'est retrouvée dans le bloc de défaillance. Les codes écrits en objectif-c.

- (NSURLSessionUploadTask *)uploadImageTask:(NSMutableDictionary *)dictionary 
{ 
    NSString *s3BucketUrl = [dictionary objectForKey:@"s3BucketUrl"]; 

    NSData *imageData = [dictionary objectForKey:@"imageData"]; 

    NSString *contentType = [dictionary objectForKey:@"contentType"]; 

    NSString *filename = [dictionary objectForKey:@"filename"]; 

    NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:s3BucketUrl parameters:dictionary constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { 

     [formData appendPartWithFileData:imageData name:@"file" fileName:filename mimeType:contentType]; 
    } error:nil]; 

    AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; 

    NSURLSessionUploadTask *uploadTask = [[NSURLSessionUploadTask alloc] init]; 
    uploadTask = [manager 
        uploadTaskWithStreamedRequest:request 
        progress:^(NSProgress * _Nonnull uploadProgress) { 
         // This is not called back on the main queue. 
         // You are responsible for dispatching to the main queue for UI updates 
         dispatch_async(dispatch_get_main_queue(), ^{ 
          //Update the progress view 

         }); 
        } 
        completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) { 
         if (!error) { 

          if (self.delegate != nil && [self.delegate respondsToSelector:@selector(onUploadImageTask:)]) 
          { 
           [self.delegate onUploadImageTask:nil]; 
          } 

         } else { 

          if (self.delegate != nil && [self.delegate respondsToSelector:@selector(onUploadImageTask:)]) 
          { 
           [self.delegate onUploadImageTask:error]; 
          } 
         } 
        }]; 

    [uploadTask resume]; 

    return uploadTask; 
} 

L'erreur que je reçois est

Code d'erreur Domain = = -1011 de com.alamofire.error.serialization.response "Échec de la demande: mauvaise demande (400)" UserInfo = {NSUnderlyingError = 0x170248940 {Erreur domaine = com.alamofire.error.serialization.response Code = -1016 "Demande échouée: type de contenu inacceptable: application/xml" UserInfo = {com.alamofire.serialization.response.error.response = { URL: https://....s3.amazonaws.com/} {code d'état: 400, en-têtes { Connexion = fermer; "Content-Type" = "application/xml"; Date = "Mar, 20 Dec 2016 01:53:47 GMT"; Serveur = AmazonS3; "Transfer-Encoding" = Identité; "x-amz-id-2" = "....."; "x-amz-request-id" = ....; }},

J'ai essayé de changer le type de contenu pour la réponse sérialiseur et échouent toujours.

Si vous ne chargez une vidéo ou une image, puis donner comme nul

UTILISATION:

#pragma -mark callwebservice for login 
    -(void)callWebserviceFor_upload_Sticker { 
    // Check whether Company user login or Individual User login. 
    [SVProgressHUD setDefaultMaskType:SVProgressHUDMaskTypeClear]; 

    //user_id, user_token, emoji_weburl(optional), emoji_picture(file) 
    NSMutableDictionary *dict_user_data = [Utility getUserPlistData]; 
    NSMutableDictionary *params = [[NSMutableDictionary alloc]init]; 
    [params setValue:[dict_user_data valueForKey:@"user_id"] forKey:@"user_id"]; 
    [params setValue:[dict_user_data valueForKey:@"user_token"] forKey:@"user_token"]; 
    NSLog(@"%@",params); 

    NSMutableDictionary *imgParams = [[NSMutableDictionary alloc]init]; 
    [imgParams setValue:UIImageJPEGRepresentation(img_to_upload, 0) forKey:@"emoji_picture"]; 

    void (^successed)(id _responseObject) = ^(id _responseObject) 
    { 
     NSLog(@"%@",_responseObject); 
     //Your logic after success 
    } ; 
    void (^failure)(NSError* _error) = ^(NSError* _error) { 
     [SVProgressHUD showErrorWithStatus:@"Failed"]; 
    } ; 

[[WebServiceHendler sharedManager]callWebserviceToUploadImageWithParams:params imgParams:imgParams videoParms:nil action:UPDATE_EMOJI success:successed failure:failure]; 
}
