libmaia

libmaia is a easy-to-use XML-RPC library for Qt!

compiling libmaia

qmake

Qt Datatypes

Allowed types for Argument and Return Values:

C++/Qt-Types	XMLRPC-Types
----------------------------------------
* int           <int></int>
* bool          <bool></bool>
* double        <double></double>
* QString       <string></string>
* QDateTime     <datetime.iso8601></datetime.iso8601>

* QVariantList  <array></array>

using libmaia

1. qmake: your Project file (.pro) should contain

   INCLUDEPATH += /path/to/libmaia
   LIBS += /path/to/libmaia/libmaia.a
   QT   += xml network
   

2. in your header file include

    #include "maiaXmlRpcClient.h"
   

   and / or

    #include "maiaXmlRpcServer.h"
   

3. create object

   server:

    MaiaXmlRpcServer *server = new MaiaXmlRpcServer(8080, this);
   

   client:

    MaiaXmlRpcClient *client = new MaiaXmlRpcClient(QUrl("http://localhost:8080/RPC2"), this);
   

4. register a method

   your method has to be a Qt Slot.

    // example method:
    QString MyClass::myMethod(int param1, QString param2) {
    	if(param1 > 5)
    		return param2;
    	else
    		return "not bigger than 5";
    }
   
    // register it:
    // "example.methodName" <- used to identify the method over xml-rpc
    // this <- pointer to the class which contains the method you would export
    // "myMethod" the name of the method
    server->addMethod("example.methodName", this, "myMethod");
   

5. call a method

   when calling a method you need three things:

   1. a Slot for the MethodResponse
   2. a Slot for the FaultResponse
   3. a QVariantList containig the arguments for the RPC-Method

   example code:

    void MyClientClass::myResponseMethod(QVariant &arg) {
    	// do something with the arg
    }
   
    void MyClientClass::myFaultResponse(int error, const QString &message) {
    	qDebug() << "An Error occoured, Code: " << error << " Message: " << message;
    }
   
    QVariantList args;
    args << 5;
    args << "second argument";
   
    rpcClient->call("example.methodName", args,
    	this, SLOT(myResponseMethod(QVariant&)),
    	this, SLOT(myFaultResponse(int, const QString &)));
