Using Qobject reflection to achieve JSONRPC

The params array in the 1.JSONRPC request generates a signature

   Static QString Signaturefromjsonarray (const Qjsonarray &Array)    {        qstringlist list;         foreach (const Qjsonvalue &V, array)        {            list<<jstypetostring (V.type ());        }         return list.join (",");    }

A method within a 2.QObject object generates a signature

Static QString Signaturefrommethod (const Qmetamethod &method)    {        qstringlist list;          for (int i=0; I<method.parametercount (); i++)        {            int type = Method.parametertype (i);            List<<jstypetostring (Convertvarianttypetojstype (type));        }         return list.join (",");    }

3. Find the signature in the Qobject instance (slightly), the same is called

    StaticQvariantlist Createparametervariantlist (ConstQmetamethod &method,ConstQjsonarray &Array)        {qvariantlist varlist;  for(intI=0; I<method.parametercount (); i++)        {            intType =Method.parametertype (i); Qvariant v=convertjsvaluetovariant (Type, array.at (i));        Varlist.append (v); }        returnvarlist; }     StaticQvariant Invoke (qobject*Object,ConstQmetamethod &method,ConstQjsonarray &params) {Qvarlengtharray<void*,Ten>Invokeparams; //Press-In return value, parameter        intReturnType =Method.returntype (); if(returntype==qmetatype::void) {ReturnType=Qmetatype::unknowntype;        } qvariant returnvalue (ReturnType, nullptr);        Invokeparams.append (Returnvalue.data ()); //Press-In ParametersQvariantlist varlist = Createparametervariantlist (method,params); foreach(ConstQvariant &V, varlist) {Invokeparams.append (const_cast<void*>(V.constdata ())); }        //called        Object-Qt_metacall (Qmetaobject::invokemetamethod, Method.methodindex (), Invokeparams.data ()); returnreturnvalue; }

Key line of code: object->qt_metacall (Qmetaobject::invokemetamethod, Method.methodindex (), Invokeparams.data ());
