任务编写一个XML一个请求类Request一个反应类

1、一、任务：编写一个 XML, 个请求类(Request), 一个反应类(Response)。使Request能提取XML的信息，Response能用返回并显示提取的信息。并编写一个测试来验证程 序可以实现需要实现的函数。最后，附上说明文档。二、说明：1. Request 类概述：一个储存被解析过的 XML的类(parsed xml request)，可以利用 Request向Service类 发出请求，使 Service 能提取各种信息需要实现的函数 ：/ 提取各种信息的函数void Service:getGeneralInfo( Request & request,string &a

2、mp; serviceType,PType & type,string & date,string & name,double & amount)/get type,e.g Astring reqType;if( request.isTypeSet( ) )reqType = request.getType( );if( reqType = "A" )type = A;if( reqType = "B" )type = B;if( reqType = "C" )type = C;if( serviceT

3、ype = "pClient" ) / obtain information in pClient node of xml requestProject pClient;if( request.isProjectSet( ) )pClient = request.getProject( );if( pClient.isAmountSet( ) )amount = pClient.getAmount( );if( pClient.isDateSet( ) )date = pClient.getDate( );if( pClient.isNameSet( ) )name = p

4、Client.getName( );elsename = "N.A,"2. Response 类概述：是一个Response Object,为Serive类显示相应信息需要实现的函数：/function to invoke servicevoid Service:solve( Request & request, Response & response )stringstype;problemType pType;stringdate;stringname;doubleamountgetGeneralInfo( request, stype, pType,

5、date,name, amount );/first check if service type involved is pClientif( stype = "pClient" )switch( pType )case A: createMyResponse( response ); break;case B: createYourResponse( response ); break;case C:createHisResponse( response ); break;default:err << "Ptype invalid " er

6、ror( err.str( ) ); break;/ creates response to My problem typevoid Service:createMyResponse(Response & response) MyClass myClass; vector<MyClass> myFinal; myClass.setName("My"); myClass.setType("My"); myClass.setDate (20091001); myFinal.push_back(myClass);MyVector myVec

7、tor; myVector.setMyVec(myFinal);MyResponse mResponse; mResponse.setMyFinal(myVector); response.setMyResponse(mResponse);/ creates response to Your problem typevoid Service:createYourResponse(Response &response) YourClass yourClass; vector<YourClass> yourFinal; yourClass.setName("Yours

8、"); yourClass.setType("Yours"); yourClass.setDate (20090411); yourFinal.push_back(yourClass);YourVector yourVector; yourVector.setYourVec(yourFinal);yourResponse yResponse;yResponse.setYourFinal(yourVector); response.setYourResponse(yResponse);void Service:createHisResponse(Response &

9、amp;response)HisClass hisClass; vector<HisClass> hisFinal; hisClass.setName("His"); hisClass.setType("His"); hisClass.setDate(20080911); hisFinal.push_back(hisClass);HisVector hisVector; hisVector.setHisVec(hisFinal);HisReponse hResponse; hResponse.setHisFinal(hisVector); response.setHisResponse(h
