AFNetworking 3.0 Multipart form data for uploading image error


I've been trying to upload an image to my AWS server using multipart form data afnetworking 3.0 but apparently, every image I tried to upload ended up in the failure block. The codes in written in objective-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;
}

The error I'm getting is

Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: bad request (400)" UserInfo={NSUnderlyingError=0x170248940 {Error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: application/xml" UserInfo={com.alamofire.serialization.response.error.response= { URL: https://....s3.amazonaws.com/ } { status code: 400, headers { Connection = close; "Content-Type" = "application/xml"; Date = "Tue, 20 Dec 2016 01:53:47 GMT"; Server = AmazonS3; "Transfer-Encoding" = Identity; "x-amz-id-2" = "....."; "x-amz-request-id" = ....; } },

I tried changing the content-type for the response serializer and still fail.


Solution

  • Use this method

    -(void)callWebserviceToUploadImageWithParams:(NSMutableDictionary *)_params imgParams:(NSMutableDictionary *)_imgParams videoParms:(NSMutableDictionary *)_videoParams action:(NSString *)_action success:(void (^)(id))_success failure:(void (^)(NSError *))_failure
    
    {
        if ([[AFNetworkReachabilityManager sharedManager] isReachable]) {

            }
        }
    }
    

    If you are not uploading any video or image then give as nil

    USE:

    #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];
    }
