这是关于一些日子,我努力尝试将使用Qt的C++代码片段翻译为objective-c,这是为了解析来自服务器的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。将C++翻译成目标C
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;
}
这里是我的代码:
- (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);
}
为什么你不能继续使用Qt?你的翻译工作是很多无聊的工作! –
因为我没有在我的目标c项目中使用Qt。我们可以在目标c中使用Qt吗? –
然后不要考虑将一些Qt代码翻译成Objective C,而是要从头开始重写*。在这种情况下,除了作为灵感来源之外,您并不关心旧的Qt代码。然后你的问题可能变成:“如何在Objective C中提供一些HTTP数据给一些XML数据”(我不知道这个问题,而不是Objective C中的编码!)。顺便说一句,这样的问题不属于StackOverflow,除非你显示一些代码。 –
