iphone发布请求标题

Question

I am going to develop web services based on REST API. It is my first project of web services.

I have a question regarding web services-iPhone app.

Suppose when a user logged in using iPhone app his will get authentication token.

Using this token he/she wiil be authorized to use futher operation of app . I am planing about that iPhone app needs to be send hearders along with post/get request method with authentication key in herders.

Request looks like: www.mydomaoin.com

But to authorize on server I need to pass special parameters to Header of request:

Headers: X-Testing-Auth-Secret: kI7wGju76kjhJHGklk76
Headers: Content-Type : application/json

which will be used in controller (zend framework)

public function preDispatch()  
{
    $request = new Zend_Controller_Request_Http();
    $key = $request->getHeader('X-Testing-Auth-Secret');
    $type = $request->getHeader('Content-Type');
}

I don't know an iPhone capable for sending headers or not. As as in case of android.

I am a php developer

Please help me

There are some delegate methods you can use.

-(void) parser:(NSXMLParser *) parser
didStartElement:(NSString *) elementName``
  namespaceURI:(NSString *) namespaceURI
 qualifiedName:(NSString *) qName
   attributes:(NSDictionary *) attributeDict {

    if( [elementName isEqualToString:@"AddGeneralInformationResult"])
   {
    if (!soapResults)
    {
        soapResults = [[NSMutableString alloc] init];
    }
    elementFound = YES;
   }


    }

  -(void)parser:(NSXMLParser *) parser foundCharacters:(NSString *)string
   {
if (elementFound)
{
    [soapResults appendString: string];
}
}

-(void)parser:(NSXMLParser *)parser
 didEndElement:(NSString *)elementName
  namespaceURI:(NSString *)namespaceURI
  qualifiedName:(NSString *)qName
 {

 if ([elementName isEqualToString:@"AddGeneralInformationResult"])
 {
    elementFound = NO;
    //NSLog(@"AddGeneralInformationResult %@",soapResults);
    if([soapResults isEqualToString:@"true"])
    {


  [objDB updateDatabaseTable:@"GeneralInformation":@"Yes":
    [[arrGenralInfo          objectAtIndex:0] intValue]];
    }
    [soapResults setString:@""];
    elementFound = FALSE;
   }


  }
 -(void) connection:(NSURLConnection *) connection
 didReceiveResponse:(NSURLResponse *) response {
 [webData setLength: 0];

//NSLog(@"receive response");
  }  

 -(void) connection:(NSURLConnection *) connection
 didReceiveData:(NSData *) data {
  [webData appendData:data];
  }

    -(void) connection:(NSURLConnection *) connection
       didFailWithError:(NSError *) error {

    //NSLog(@"Server error");

    }

  -(void) connectionDidFinishLoading:(NSURLConnection *) connection {
     //NSLog(@"DONE. Received Bytes: %d", [webData length]);
      NSString *theXML = [[NSString alloc]
                    initWithBytes: [webData mutableBytes]
                    length:[webData length]
                    encoding:NSUTF8StringEncoding];
//---shows the XML---
//NSLog(@"%@",theXML);

// [activityIndicator stopAnimating];
if (xmlParser)
{

}
xmlParser = [[NSXMLParser alloc] initWithData: webData];
[xmlParser setDelegate: self];
[xmlParser setShouldResolveExternalEntities:YES];
[xmlParser parse];

}
