Hello Everyone !

Nowaday I tried to send a "Soap Request" via the Object HttpRequest
and looking for the result coming from execute Methode.

I have tried this kind of code :

#include <Core/Core.h>
using namespace Upp;
CONSOLE_APP_MAIN
{
	String reponse="";
	auto test = new HttpRequest("http://www.holidaywebservice.com//HolidayService_v2/HolidayService2.asmx?wsdl");
	test->Timeout(5000);
	test->ContentType("text/xml");
	test->Post("<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/' xmlns:hs='http://www.holidaywebservice.com/HolidayService_v2/'><soapenv:Body><hs:GetHolidaysForMonth><hs:year>2018</hs:year><hs:countryCode>UnitedStates</hs:countryCode><hs:month>11</hs:month></hs:GetHolidaysForMonth></soapenv:Body></soapenv:Envelope>");
	reponse = test->Execute();
	LOG(reponse);
}

But it crash with the message : "heap leaks detected" and the exitcode 0.
The heap leaks detected seems related to the LOG/"reponse"
so I tried without them and the result is now a crash with the exitcode : 3224225477

Can someone explain me why this occur ?

Sorry for my bad english, Thanks in advance.

Hello Xemuth,

Because you've created an HttpRequest on the heap and you forgot to delete it at the end. Smile

This is the VERY reason you should avoid using new/delete.
Try to allocate resources on the stack, or use containers (e.g. One<> for single instance, Array<> for mulitple instances.)

	HttpRequest test("http://www.holidaywebservice.com//HolidayService_v2/HolidayService2.asmx?wsdl");
	test.Timeout(5000);
	test.ContentType("text/xml");
	test.Post("<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/' xmlns:hs='http://www.holidaywebservice.com/HolidayService_v2/'><soapenv:Body><hs:GetHolidaysForMonth><hs:year>2018</hs:year><hs:countryCode>UnitedStates</hs:countryCode><hs:month>11</hs:month></hs:GetHolidaysForMonth></soapenv:Body></soapenv:Envelope>");
	reponse = test.Execute();
	LOG(reponse);

Best regards,
Oblivion

Hello Oblivion,

Indeed it fixed the crash ! thanks for your quick reply !

I did not know it was a difference between HttpRequest test(); and HttpRequest test = new HttpRequest();

Thanks a lot !
