copied!<p>It's about some days now i'm struggling doing Archaeology work trying to translating a c++ code snippet using Qt to objective-c, it's for sending a request in order to parse xml coming from a server as a response. I really try but can't achieve it. If someone could give me some help.</p> <pre><code>void RestClient::_prepareRequest( QNetworkRequest& a_request, const QString& a_uri ) { QSslConfiguration config(QSslConfiguration::defaultConfiguration()); config.setProtocol(QSsl::SslV3); config.setSslOption(QSsl::SslOptionDisableServerNameIndication, true); a_request.setSslConfiguration(config); a_request.setRawHeader("Accept", "application/xml"); a_request.setRawHeader("Content-Type", "application/x-www-form-urlencoded"); QByteArray l_api_key; l_api_key.append( toQString( m_api_key) ); QByteArray l_request_hash; l_request_hash.append( toQString( _buildRequestHash( toStlString(a_uri) ) ) ); a_request.setRawHeader("EMApikey", l_api_key ); a_request.setRawHeader("EMRequestHash", l_request_hash ); a_request.setUrl( QUrl( a_uri ) ); } - (NSString *)hmacsha1:(NSString *)data secret:(NSString *)key { const char *cKey = [key cStringUsingEncoding:NSASCIIStringEncoding]; const char *cData = [data cStringUsingEncoding:NSASCIIStringEncoding]; unsigned char cHMAC[CC_SHA1_DIGEST_LENGTH]; CCHmac(kCCHmacAlgSHA1, cKey, strlen(cKey), cData, strlen(cData), cHMAC); NSData *HMAC = [[NSData alloc] initWithBytes:cHMAC length:sizeof(cHMAC)]; NSString *hash = [HMAC base64EncodedStringWithOptions:(nil)]; return hash; </code></pre> <p>}</p> <p>and here is my code :</p> <pre><code>- (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; if ([stories count] == 0) { NSString * myServerUrl = @"**************"; NSString * l_api_key = @"*******************************"; NSString * l_secret_key = @"************************************"; NSMutableURLRequest *theRequest=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:[myServerUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60.0]; //do post request for parameter passing [theRequest setHTTPMethod:@"GET"]; [theRequest setValue:@"xml" forHTTPHeaderField:@"xml"]; [theRequest addValue:@"l_api_key" forHTTPHeaderField: l_api_key]; [theRequest addValue:@"l_request_hash" forHTTPHeaderField:[self hmacsha1:l_api_key secret:l_secret_key]]; NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if( theConnection ) { NSLog(@"we get here !"); NSURL *webData = [[NSMutableData data] retain]; [self parseXMLFileAtURL: webData]; cellSize = CGSizeMake([newsTable bounds].size.width, 60); } else { NSLog(@"theConnection is NULL"); } [theConnection release]; } //cellSize = CGSizeMake([newsTable bounds].size.width, 60); </code></pre> <p>}</p>
