在黑莓10级联上创建http通信

我是开发黑莓10级联的新手。我需要使用httpget连接文件xml并从它获取dat以将其显示在列表中。有一个例子可以帮助我做http通信或导师吗？所有这样https://developer.blackberry.com/cascades/documentation/device_platform/networking/tutorial_http_comm.html HTTP通信链路没有工作，我得到404在黑莓10级联上创建http通信

使用QNetworkAccessManager，QNetworkRequest和QNetworkReply类进行HTTP连接。

QNetworkAccessManager* netManager = new QNetworkAccessManager(); 
QUrl myurl(yourURL); 
QNetworkRequest req(url); 

QNetworkReply* ipReply = netManager->get(req); 
connect(ipReply, SIGNAL(finished(QNetworkReply*)), this, SLOT(onReply(QNetworkReply*))); 
}

在onReply插槽解析您回应

if (reply) { 
    if (reply->error() == QNetworkReply::NoError) { 
     int available = reply->bytesAvailable(); 
     if (available > 0) { 
      int bufSize = sizeof(char) * available + sizeof(char); 
      QByteArray buffer(bufSize, 0); 
      int read = reply->read(buffer.data(), available); 
      response = QString(buffer); 
     } 
    } else { 
     response = 
       QString("Error: ") + reply->errorString() 
         + QString(" status:") 
         + reply->attribute(
           QNetworkRequest::HttpStatusCodeAttribute).toString(); 
    } 
    reply->deleteLater(); 
}

使用此代码...

QNetworkAccessManager* netManager = new QNetworkAccessManager(); 
     QUrl myurl("http://******"); 
     QNetworkRequest req(myurl); 

    QNetworkReply* ipReply = netManager->get(req); 

    QEventLoop eventLoop; 
    QObject::connect(ipReply, SIGNAL(finished()), &eventLoop, SLOT(quit())); 
    eventLoop.exec(); 
    std::cout << "finished" << std::endl; //request finished here 
    requestFinished(ipReply);
