hOpen = WinHttpOpen(L"Aurora Console App", WINHTTP_ACCESS_TYPE_DEFAULT_PROXY,
			WINHTTP_NO_PROXY_NAME, WINHTTP_NO_PROXY_BYPASS, 0);
		if (!hOpen) {
			wprintf(L"WinHttpOpen failed (0x%.8X)\n", GetLastError());
			break;
		}
		hConnect = WinHttpConnect(hOpen, L"raw.github.com", INTERNET_DEFAULT_HTTPS_PORT, 0);
		if (!hConnect) {
			wprintf(L"WinHttpConnect failed (0x%.8X)\n", GetLastError());
			break;
		}
		LPCWSTR types[2];
		types[0] = L"text/html";
		types[1] = 0;
		// use flag WINHTTP_FLAG_SECURE to initiate SSL
		hRequest = WinHttpOpenRequest(hConnect, L"GET", L"zpfzzz/test/master/README.md",
			NULL, WINHTTP_NO_REFERER, &types[0], WINHTTP_FLAG_SECURE);
		if (!hRequest)
		{
			wprintf(L"WinHttpOpenRequest failed (0x%.8X)\n", GetLastError());
			break;
		}

		DWORD dwData = 0;
		DWORD dwSize = sizeof(dwData);
		if (!WinHttpQueryOption(hRequest, WINHTTP_OPTION_SECURE_PROTOCOLS, &dwData, &dwSize))
		{
			DWORD err = GetLastError();
			int i = 0;
		}

现在在WinHttpQueryOption 查询 WINHTTP_OPTION_SECURE_PROTOCOLS err 返回值是87,但是参数没有填错呀！
