iphone发布请求标头

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

Answer 1

You can use the following code

NSMutableURLRequest *req = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:url]];
    NSString *post = @"your json";
    //NSLog(@"%@",post);
    NSData *postdata = [NSData dataWithBytes:[post UTF8String] length:[post length] ];
    [req setHTTPMethod:@"POST"];
    [req setValue:@"application/json" forHTTPHeaderField:@"content-type"];
    [req setValue:@"kI7wGju76kjhJHGklk76" forHTTPHeaderField:@"Content-Length"];
    [req setValue:[NSString stringWithFormat:@"%d",[postdata length]] forHTTPHeaderField:@"X-Testing-Auth-Secret"];
    [req setHTTPBody:postdata];

    (void)[NSURLConnection connectionWithRequest:req delegate:self];

Answer 2

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];

}

Answer 3

是的，您可以从iPhone和Android手机发送标头

Answer 4

This is how you can append tokens in 'Post' request. Sample code :

NSURL *url = [NSURL URLWithString:@"http://www.deveinvoice.sirus/process/user.asmx"];
req = [NSMutableURLRequest requestWithURL:url];

//---set the headers---

NSString *msgLength = [NSString stringWithFormat:@"%d",[strSoapMsg length]];
[req addValue:@"application/soap+xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[req addValue:@"http://tempuri.org/CheckTransactionIDExist" forHTTPHeaderField:@"SOAPAction"];
[req addValue:msgLength forHTTPHeaderField:@"Content-Length"];

//---set the HTTP method and body---

[req setHTTPMethod:@"POST"];
[req setHTTPBody: [strSoapMsg dataUsingEncoding:NSUTF8StringEncoding]];

Answer 5

Request for parsing xml data.

Suppose that is the method for request-

-(void)PostPipeSeAamAnomaly {

NSString *soapMsg =
[NSString stringWithFormat:
 @"<?xml version=\"1.0\" encoding=\"utf-8\"?>"
 "<soap:Envelope xmlns:xsi="

//NSLog(@"%@",soapMsg);
NSURL *url = [NSURL URLWithString:
              WEBSERVICEURL];
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];

//---set the various headers---
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMsg length]];
[req addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[req addValue:@"http://tempuri.org/PostPipeSeAamAnomaly" forHTTPHeaderField:@"SOAPAction"];
[req addValue:msgLength forHTTPHeaderField:@"Content-Length"];

//---set the HTTP method and body---
[req setHTTPMethod:@"POST"];
[req setHTTPBody:[soapMsg dataUsingEncoding:NSUTF8StringEncoding]];

//[activityIndicator startAnimating];


conn = [[NSURLConnection alloc] initWithRequest:req delegate:self];
if (conn) {
    webData = [NSMutableData data];


    //NSLog(@"go to delegateMethods");
}
