WinHTTP w C++

[QuQu97]

Cześć,

 

dotychczas WinHTTP używałem w AutoIt, ale teraz chciałbym przejść na C++. I tu pojawiają się problemy, otóż przy próbie kompilacji najprostrzego programu:

 

 

#include <windows.h>
#pragma comment(lib, "winhttp.lib")
#include <winhttp.h>

using namespace std;

int main(){


return 0;
}

 

 

otrzymuję wiele błędów:

Bibliotekę winhttp.lib dodałem do kompilatora.

 

I teraz pytanie, czy w C++ używa się WinHTTP, czy może jest przeznaczony do C/C#?

Jeżeli odpowiedź na pierwsze pytanie brzmi nie, to może jakiś zamiennik np. WinINet?

Ewentualnie prosiłbym o jakieś nakierowanie jaki język z jakim API najlepiej używać.

Refresh?

    I teraz pytanie, czy w C++ używa się WinHTTP

 

 

TAK.

 

Sprobuj Winhttp.h zamiast winhttp.h

 

P.S do zapytan HTTP, FTP itd polecam curla. Bardzo przyjemna biblioteka

[QuQu97]

Winhttp.h było złe, mimo, że pobrałem to w SDK to nie chciało działać, po pobraniu z innego źródła wszystko jest w porządku.

[twarożek]

Pewnie nie korzystałeś z kompilatora Micro$oftu? W takim razie to nie miało prawa się skompilować bo w nagłówkach z SDK masz dodatki do deklaracji funkcji takie jak np: '__out', '__in' itd... a zwykły kompilator sobie z tym nie poradzi .

 

Przynajmniej teraz znasz przyczynę swojego problemu.

[QuQu97]

Kompilatora używam GCC zainstalowałem go razem z C::B + MinGW.

[twarożek]

No właśnie, SDK z Visualem by działało, ale teraz nie ma raczej powodów żeby zmieniać środowisko :P
