SDK ile örnek bir http sınıfı derlemeye çalışıyorum ve bazı garip bağlantı hataları alıyorum ... Emin bir seçeneği eksik bir seçenekle veya dizine göre ...C++ WinHttp/Windows SDK ile sorun derleme
Gördüğünüz gibi C++ konusunda uzman değilim, ancak herhangi bir yardım arıyorum.
Örnek sınıfımı dahil ettim. Windows SDK'yi de kurdum. Kurulumlarım veya başka bir şey hakkında başka bir bilgiye ihtiyacınız varsa, lütfen sorun. Birinin beni çalışan bir WinHttp SDK örnek projesine yönlendirmesini tercih ederim.
