我試圖建立一個http連接到我自己的域並返回一個字符串。我有它與www.microsoft.com工作,但當我更改域www.atomic-gaming.info(我的域名)我得到一個錯誤12029,如果我改變鏈接到www.yahoo.com我得到一個錯誤12017WinHTTP錯誤12029無法連接
代碼
DWORD dwSize = 0;
DWORD dwDownloaded = 0;
LPSTR pszOutBuffer;
BOOL bResults = FALSE;
HINTERNET hSession = NULL,
hConnect = NULL,
hRequest = NULL;
// Use WinHttpOpen to obtain a session handle.
hSession = WinHttpOpen(L"WinHTTP Example/1.0",

printf("Error %u in WinHttpReadData.\n", GetLastError());
else

delete [] pszOutBuffer;
}
} while(dwSize > 0);
}
// Report any errors.
if(!bResults)

// Close any open handles.
if(hRequest) WinHttpCloseHandle(hRequest);

能有人給我一個想法,爲什麼這個只有microsoft.com的作品?我將如何去修復它?
將那些什麼錯誤代碼的意思可能是更有幫助 – Twifty
@Waldermort對於它的價值,12029是ERROR_WINHTTP_CANNOT_CONNECT和12017是ERROR_WINHTTP_OPERATION_CANCELLED –
@IgorTandetnik我希望能鼓勵海報第一次使用谷歌標識錯誤,也許讓他了解他的問題可能是什麼。另一方面,我真的希望MS使用枚舉而不是錯誤代碼,使它們更易於閱讀。 – Twifty
