现在大约有几天了,我正在努力进行考古工作,试图将使用 Qt 的 c++ 代码片段翻译为 Objective-c,它用于发送请求以解析来自服务器的 xml 作为响应。我真的尝试但无法实现。如果有人可以给我一些帮助。
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;
}
这是我的代码:
- (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);
}
