Trying upload data in Local Server using MKNetworkKit

Question

I want to upload data, images, txt files, pdf documents , etc. Im using MKNetworkKit to connect cleanly. With examples of this framework i try do it. I add to my proyect a class extends of MKNetworkEngine with a method for upload from file:

#import "MKNetworkOperation.h"
#import "MKNetworkEngine.h"

@interface Uploader : MKNetworkEngine
-(MKNetworkOperation*) uploadFromFile:(NSString*) file 
                              onError:(MKNKErrorBlock) errorBlock; 
@end



#import "Uploader.h"

@implementation Uploader


-(MKNetworkOperation*) uploadFromFile:(NSString*) file 
                              onError:(MKNKErrorBlock) errorBlock 
{

    MKNetworkOperation *op = [self operationWithPath:@"IP:PORT/PROYECT/" 
                                              params:nil
                                          httpMethod:@"POST"];

    [op addFile:file forKey:@"upload"];
    [op setFreezable:YES];

    [op onCompletion:^(MKNetworkOperation* completedOperation) 
     {
         NSString *xmlString = [completedOperation responseString];
         NSUInteger start = [xmlString rangeOfString:@"<mediaurl>"].location;
          if(start == NSNotFound) 
          {
          NSLog(@"%@", xmlString);
          errorBlock(nil);
          return;
          }
          xmlString = [xmlString substringFromIndex:start + @"<mediaurl>".length];
          NSUInteger end = [xmlString rangeOfString:@"</mediaurl>"].location;
          xmlString = [xmlString substringToIndex:end];
     }
             onError:^(NSError* error) 
     {
         errorBlock(error);
     }];

    [self enqueueOperation:op];
    return op;

}
@end

I have added i my interface a button for upload file, and in my controller i,ve created a method with this content:

-(IBAction)uploadImageTapped:(id)sender 
{

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);

    NSString *cachesDirectory = [paths objectAtIndex:0];
    NSString *uploadPath = [NSString stringWithFormat:@"%@/Imagen.jpg",cachesDirectory];
    //NSLog(@"%@",uploadPath);

    self.uploadOperation = [ApplicationDelegate.sampleUploader uploadFromFile:uploadPath  onError:^(NSError* error) 
                            {
                                [UIAlertView showWithError:error];
                            }];
  }

Finally I,ve added a Uploader object in my delegate of app:

@property (strong, nonatomic) Uploader *sampleUploader;

and

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    UISplitViewController *splitViewController = (UISplitViewController *)self.window.rootViewController;
    UINavigationController *navigationController = [splitViewController.viewControllers lastObject];
    splitViewController.delegate = (id)navigationController.topViewController;

    //Uploader
    self.sampleUploader = [[Uploader alloc] initWithHostName:@"http://IP:PORT"
                                          customHeaderFields:nil];

    return YES;
}

My problem is that i want to can upload files, my localhost is not reachable and i dont know why....

Any ideas???

RichS is right. You shouldn't use http (protocol) in the hostname.

[I've stumbled across your question whilst looking for some help myself with MKNetworkingKit.]

Quickly reading through you code, I wonder if you should remove the 'http://' from your initWithHostName. I'm sure the kit add 'http://' somewhere within its own init.

Hi, I've got my instance working now. It is pretty much the same as your code. But, I've noticed you've got 'operationWithPath', but the parameter looks like a URI. You may need to use 'operationWithString' if you are passing in a full URI. Not sure if this helps. PS: I should be able to extract my code from my project and post if you still can't get it working. – RichS Apr 05 '12 at 12:32
