WebService

Hii EveryOne

We have two prog :
1- Client that represents the interface (Created by : QtQuick/QML) for entering data
2- Serveur Web (Java/JEE) that should menage the database

Communication between Client(Qml, Qt/C++) and Serveur Web should be done by : Webservice : Rest

I'm beginner in Webservice, I don't know where to start.
How can I establish the communication?
Steps to follow?

Cheers,

You can try something like this for the Client (Qt)
(Be Aware that following code is rudimental and is not tested)
Ist not really a howto but i think it will help you in your first steps

Code:

---

QNetworkAccessManager networkManager;
 QNetworkRequest request;
 QByteArray arr;
 QString requestData = "";
 QString requestUrl= "www.google.at";
 
 arr.append(requestData);                                
 
 request.setHeader(QNetworkRequest::ContentTypeHeader, QVariant( QString("text/xml;charset=UTF-8")));
 request.setHeader(QNetworkRequest::ContentLengthHeader, QVariant( qulonglong(arr.size()) ));
 request.setAttribute(QNetworkRequest::CacheLoadControlAttribute, QVariant( int(QNetworkRequest::AlwaysNetwork) ));
request.setUrl(QUrl(requestUrl));
 
 QObject::connect(networkManager, SIGNAL(finished(QNetworkReply*)), this, SLOT(onRequestFinished(QNetworkReply*)));
 QObject::connect(networkManager, SIGNAL(authenticationRequired(QNetworkReply*,QAuthenticator*)), this, SLOT(onAuthenticationRequired(QNetworkReply*, QAuthenticator*)));
 
 networkReply = networkManager.post(request, arr);
 QObject::connect(this, SIGNAL(sigCancelRequest()), networkReply, SLOT(abort()));
