POST Carga jpeg con AFNetworking

Question

No puedo entender por qué esto no funciona cuando uso AFNetworking. Funcionó con ASIHTTP. Todo esto es muy nuevo para mi. Pero no puedo entender por qué los archivos ya no se transfieren de $ _FILES a la HD del servidor. Aquí está el código IOS:

- (IBAction)uploadPressed 
{ 
[self.fileName resignFirstResponder]; 
NSURL *remoteUrl = [NSURL URLWithString:@"http://mysite.com"]; 

NSTimeInterval timeInterval = [NSDate timeIntervalSinceReferenceDate]; 
NSString *photoName=[NSString stringWithFormat:@"%lf-Photo.jpeg",timeInterval]; 

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 

// the path to write file 
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:photoName]; 
NSData * photoImageData = UIImageJPEGRepresentation(self.remoteImage.image, 1.0); 
[photoImageData writeToFile:filePath atomically:YES]; 

NSLog(@"photo written to path: e%@", filePath); 

AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:remoteUrl]; 
NSMutableURLRequest *afRequest = [httpClient multipartFormRequestWithMethod:@"POST" 
                     path:@"/photos" 
                   parameters:nil 
                constructingBodyWithBlock:^(id <AFMultipartFormData>formData) 
            { 
             [formData appendPartWithFormData:[self.fileName.text dataUsingEncoding:NSUTF8StringEncoding] 
                    name:@"name"]; 


             [formData appendPartWithFileData:photoImageData 
                    name:self.fileName.text 
                   fileName:filePath 
                   mimeType:@"image/jpeg"]; 
            } 
            ]; 

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:afRequest]; 
[operation setUploadProgressBlock:^(NSInteger bytesWritten, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) { 

    NSLog(@"Sent %d of %d bytes", totalBytesWritten, totalBytesExpectedToWrite); 

}]; 

    [operation setCompletionBlock:^{ 
    NSLog(@"%@", operation.responseString); //Gives a very scary warning 
}]; 

[operation start];  



} 

Solía ​​hacer esto:

ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:remoteUrl]; 
[request setPostValue:self.fileName.text forKey:@"name"]; 
[request setFile:filePath forKey:@"filename"]; 
[request setDelegate:self]; 
[request startAsynchronous]; 

aquí es mi PHP:

{ 
// these could be stored in a .ini file and loaded 
// via parse_ini_file()... however, this will suffice 
// for an example 
$codes = Array(
    100 => 'Continue', 
    101 => 'Switching Protocols', 
    200 => 'OK', 
    201 => 'Created', 
    202 => 'Accepted', 
    203 => 'Non-Authoritative Information', 
    204 => 'No Content', 
    205 => 'Reset Content', 
    206 => 'Partial Content', 
    300 => 'Multiple Choices', 
    301 => 'Moved Permanently', 
    302 => 'Found', 
    303 => 'See Other', 
    304 => 'Not Modified', 
    305 => 'Use Proxy', 
    306 => '(Unused)', 
    307 => 'Temporary Redirect', 
    400 => 'Bad Request', 
    401 => 'Unauthorized', 
    402 => 'Payment Required', 
    403 => 'Forbidden', 
    404 => 'Not Found', 
    405 => 'Method Not Allowed', 
    406 => 'Not Acceptable', 
    407 => 'Proxy Authentication Required', 
    408 => 'Request Timeout', 
    409 => 'Conflict', 
    410 => 'Gone', 
    411 => 'Length Required', 
    412 => 'Precondition Failed', 
    413 => 'Request Entity Too Large', 
    414 => 'Request-URI Too Long', 
    415 => 'Unsupported Media Type', 
    416 => 'Requested Range Not Satisfiable', 
    417 => 'Expectation Failed', 
    500 => 'Internal Server Error', 
    501 => 'Not Implemented', 
    502 => 'Bad Gateway', 
    503 => 'Service Unavailable', 
    504 => 'Gateway Timeout', 
    505 => 'HTTP Version Not Supported' 
); 

return (isset($codes[$status])) ? $codes[$status] : ''; 
} 

function sendResponse($status = 200, $body = '', $content_type = 'text/html') 
{ 
$status_header = 'HTTP/1.1 ' . $status . ' ' . getStatusCodeMessage($status); 
header($status_header); 
header('Content-type: ' . $content_type); 
echo $body; 
} 

if (!empty($_FILES) && isset($_POST["name"])) { 
      $name = $_POST["name"]; 
      $tmp_name = $_FILES['filename']['tmp_name']; 
      $uploads_dir = '/var/www/cnet/photos'; 
      move_uploaded_file($tmp_name, "$uploads_dir/$name.jpg"); 
      $result = array("SUCCEEDED"); 
      sendResponse(200, json_encode($result)); 
      } else { 

      sendResponse(400, 'Nope'); 
      } 
?> 

Answer 1

No estoy muy familiarizado con lo ASI está haciendo con setPostValue:forKey:, pero es posible que le falte un parámetro name que se enviará por separado de la carga de la imagen.

¿Qué registra el cliente o el servidor, exactamente? Es el registro de bloque de progreso?

Algunos otros puntos:

• Sólo puede hacer [operation start] al final; no es necesario crear una cola de operaciones solo por eso.
• Para ayudar con el registro, establezca completionBlock en operation, con NSLog de la respuesta, o algo por el estilo.
• Es posible que desee crear una clase base AFHTTPClient con un método de clase para devolver una instancia singleton, como el cliente Gowalla API en la aplicación de ejemplo AFNetworking. Ese cliente puede administrar una única cola de operaciones para todas sus solicitudes de red.

Answer 2

Tengo una solución utilizando NSMutableURLRequest:

NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:remoteUrl]; 
[req setHTTPMethod:@"POST"]; 

NSString *contentType = [NSString stringWithFormat:@"multipart/form-data, boundary=%@", boundary]; 
[req setValue:contentType forHTTPHeaderField:@"Content-type"]; 

//adding the body: 
NSMutableData *postBody = [NSMutableData data]; 
[postBody appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[postBody appendData:[@"Content-Disposition: form-data; name=\"name\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
[postBody appendData:[name dataUsingEncoding:NSUTF8StringEncoding]]; 

[postBody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[postBody appendData:[@"Content-Disposition: form-data; name=\"filename\";\r\nfilename=\"china.jpg\"\r\nContent-Type: image/jpeg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
[postBody appendData:[NSData dataWithData:imageData]]; 
[postBody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[req setHTTPBody:postBody];

probar este fragmento de código:

NSData* sendData = [self.fileName.text dataUsingEncoding:NSUTF8StringEncoding]; 
    NSDictionary *sendDictionary = [NSDictionary dictionaryWithObject:sendData forKey:@"name"]; 
    AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:remoteUrl]; 
    NSMutableURLRequest *afRequest = [httpClient multipartFormRequestWithMethod:@"POST" 
                      path:@"/photos" 
                    parameters:sendDictionary 
                 constructingBodyWithBlock:^(id <AFMultipartFormData>formData) 
             {          
              [formData appendPartWithFileData:photoImageData 
                     name:self.fileName.text 
                    fileName:filePath 
                    mimeType:@"image/jpeg"]; 
             } 
             ]; 

    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:afRequest]; 
    [operation setUploadProgressBlock:^(NSInteger bytesWritten, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) { 

     NSLog(@"Sent %d of %d bytes", totalBytesWritten, totalBytesExpectedToWrite); 

    }]; 

    [operation setCompletionBlock:^{ 
     NSLog(@"%@", operation.responseString); //Gives a very scary warning 
    }]; 

    [operation start];
