Hello!

I want to create a http connection to a webserver and start downloading data in a QThread, but I'm having some problems.

First, my code is returning usually nothing from my searches:

Qt Code: 
  1. HTTPClass::HTTPClass(QObject *parent) :
  2.     QObject(parent)
  3. {
  4.     namConnection = new QNetworkAccessManager(this);
  5.  
  6.     connect(namConnection, SIGNAL(finished(QNetworkReply*)),
  7.              this, SLOT(slotReplyFinished(QNetworkReply*)));
  8.     connect(namConnection, SIGNAL(authenticationRequired(QNetworkReply*,QAuthenticator*)),
  9.              this, SLOT(slotAuthenticationRequired(QNetworkReply*,QAuthenticator*)));
  10.     connect(namConnection, SIGNAL(proxyAuthenticationRequired(QNetworkProxy,QAuthenticator*)),
  11.              this, SLOT(slotProxyAuthenticationRequired(QNetworkProxy,QAuthenticator*)));
  12.     connect(namConnection, SIGNAL(networkSessionConnected()),
  13.             this, SLOT(slotNetworkSessionConnected()));
  14.  
  15.     QNetworkRequest request;
  16.     request.setUrl(QUrl("http://en.wikipedia.org/wiki/Main_Page"));
  17.  
  18.     reply = namConnection->get(request);
  19.     connect(reply, SIGNAL(readyRead()), this, SLOT(slotReadyRead()));
  20.     connect(reply, SIGNAL(error(QNetworkReply::NetworkError)),
  21.             this, SLOT(slotError(QNetworkReply::NetworkError)));
  22.     connect(reply, SIGNAL(sslErrors(QList<QSslError>)),
  23.             this, SLOT(slotSslErrors(QList<QSslError>)));
  24. }
  25.  
  26. void HTTPClass::setConnectionData()
  27. {
  28.  
  29. }
  30.  
  31. void HTTPClass::slotReplyFinished(QNetworkReply *reply)
  32. {
  33.     qDebug() << reply->readAll();
  34.  
  35.     reply->deleteLater();
  36. }
  37.  
  38. void HTTPClass::slotAuthenticationRequired(QNetworkReply *reply, QAuthenticator *aut)
  39. {
  40.     qDebug() << "Ha";
  41.     //aut->setUser("Username");
  42.     //aut->setPassword("Password");
  43. }
  44.  
  45. void HTTPClass::slotProxyAuthenticationRequired(QNetworkProxy proxy, QAuthenticator *aut)
  46. {
  47.  
  48. }
  49.  
  50. void HTTPClass::slotNetworkSessionConnected()
  51. {
  52.     qDebug() << "Connected";
  53. }
  54.  
  55. void HTTPClass::slotReadyRead()
  56. {
  57.     reply->readAll();
  58. }
  59.  
  60. void HTTPClass::slotError(QNetworkReply::NetworkError error)
  61. {
  62.     qDebug() << QString::number(error);
  63. }
  64.  
  65. void HTTPClass::slotSslErrors(QList<QSslError> errors)
  66. {
  67.     qDebug() << errors[0].errorString();
  68. }

Everything I get is 3 blanck answers. ("" "" "") What am I doing wrong? I know how to download a file from the web, but not how to read data from a url.

My second question: actually I don't know how the information is in the link I actually want to connect with. It must be some kind of server, but not if its an sql server with MySQL or FTP something else. How could I know how the information is stored in the link I want to connect with? (which by the way: sharkbuss.banifinvest.com.br , gate 80, parameter: /BI3S2/get.aspx)

My third question: in order to connect myself with this link, I now I'll have to give a password and username. Where exactly in my code should I put this part?


Thanks,
