QtSoapHttpTransport and Proxy authentication

[rmagro]

Hi all,

I developed a client program able to send Soap request and to get a response from a Web Server, using the QtSoap module.

"QtSoapHttpTransport" Class anyway seem not ho handle proxy authentication..
(I mean, there is a method ..like setHost wich take as parameters proxy name, proxy port, username and pwd)

is it like this? If so, how can we manage to get throught proxy ?

Did Any of you experience something related to this problem ?

thank you for your help..

Any Idea ??

try to get IE proxy settings from
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsCurre ntVersion\Internet Settings
parameters:
ProxyEnable
ProxyOverride
ProxyServer


I suppose on a dialog you must take params and fill QAuthenticator...

void HttpSoapConnection::slotAuthenticationRequired( QNetworkReply *reply, QAuthenticator *authenticator )
{
  Q_UNUSED( reply );
 
  kWarning() << "Got http authentication request for" << authenticator->realm() <<
                "while connecting to" << endpoint_;
}

void HttpSoapConnection::slotAuthenticationRequired( QNetworkReply *reply, QAuthenticator *authenticator )
{
  Q_UNUSED( reply );

  kWarning() << "Got http authentication request for" << authenticator->realm() <<
                "while connecting to" << endpoint_;
}

Thank you Patrick for your help.

I have already abtained the information about Proxy configuration on the windows Registry..
but I do not understand than the solution proposed..

What I mean is..
I was expecting using the QtSoapHttpTransport class some method like
setProxy (ot setUser) like it is in QHTTP class..

but those similar methods are not there..right?

Can you then give a simple how to use the solution proposed..

I have something similar to the example proposed in the QT DOC

void WeatherFetcher::findTemperature(const QString &city)
 {
     QtSoapMessage message;
     message.setMethod("getTemperature", "http://weather.example.com/temperature");
     message.setMethodArgument("city", "", city);
 
     // transport is a private member of WeatherFetcher, of type QtSoapHttpTransport
     transport.setHost("www.example.com");
     connect(&transport, SIGNAL(responseReady()), SLOT(readResponse()));
 
     transport.submitRequest(message, "/weatherfetcher/fetch.asp");
 }
This is an example implementation of the readResponse() slot in the WeatherFetcher class:
 void WeatherFetcher::readResponse()
 {
     const QtSoapMessage &response = transport.getResponse();
     if (response.isFault()) {
         cout << response.faultString().toString().toLatin1().constData() << endl;
         return;
     }
 
     const QtSoapType &returnValue = response.returnValue();
     if (returnValue["temperature"].isValid()) {
     cout << "The current temperature is "
          << returnValue["temperature"].toString().toLatin1().constData()
          << " degrees Celcius." << endl;
 }

void WeatherFetcher::findTemperature(const QString &city)
 {
     QtSoapMessage message;
     message.setMethod("getTemperature", "http://weather.example.com/temperature");
     message.setMethodArgument("city", "", city);

     // transport is a private member of WeatherFetcher, of type QtSoapHttpTransport
     transport.setHost("www.example.com");
     connect(&transport, SIGNAL(responseReady()), SLOT(readResponse()));

     transport.submitRequest(message, "/weatherfetcher/fetch.asp");
 }
This is an example implementation of the readResponse() slot in the WeatherFetcher class:
 void WeatherFetcher::readResponse()
 {
     const QtSoapMessage &response = transport.getResponse();
     if (response.isFault()) {
         cout << response.faultString().toString().toLatin1().constData() << endl;
         return;
     }

     const QtSoapType &returnValue = response.returnValue();
     if (returnValue["temperature"].isValid()) {
     cout << "The current temperature is "
          << returnValue["temperature"].toString().toLatin1().constData()
          << " degrees Celcius." << endl;
 }
