记录下http和https的post方法 在C++中实现
来源无从考究了，这里记录一下
http 的post 方法
BOOL HttpPostToBusinessServer(LPCTSTR serverAddr, std::string urlParam, std::string &strHttpContent, LPDWORD statusCode);
BOOL HttpPostToBusinessServer(LPCTSTR serverAddr, std::string urlParam, std::string & strHttpContent, LPDWORD statusCode)
{
URL_COMPONENTS urlComponents;
ZeroMemory(&urlComponents, sizeof(urlComponents));
urlComponents.dwStructSize = sizeof(urlComponents);
TCHAR hostName[256];
urlComponents.lpszHostName = hostName;
urlComponents.dwHostNameLength = 256;
TCHAR path[1024];
urlComponents.lpszUrlPath = path;
urlComponents.dwUrlPathLength = 1024;
if (WinHttpCrackUrl(serverAddr, lstrlen(serverAddr), 0, &urlComponents) == FALSE)
{
return FALSE;
}
HINTERNET hSession = NULL;
HINTERNET hConnect = NULL;
HINTERNET hRequest = NULL;
BOOL bResults = FALSE;
std::wstring httpHeader;
std::wstring strUserIDParam;
hSession = WinHttpOpen(NULL, WINHTTP_ACCESS_TYPE_DEFAULT_PROXY, WINHTTP_NO_PROXY_NAME, WINHTTP_NO_PROXY_BYPASS, 0);
if (!hSession)
{
goto failure;
}
hConnect = WinHttpConnect(hSession, urlComponents.lpszHostName, urlComponents.nPort, 0);
if (!hConnect)
{
goto failure;
}
strUserIDParam = urlComponents.lpszUrlPath;
hRequest = WinHttpOpenRequest(hConnect, L"POST", strUserIDParam.c_str(), L"HTTP/1.1", WINHTTP_NO_REFERER, WINHTTP_DEFAULT_ACCEPT_TYPES, WINHTTP_FLAG_REFRESH);
if (!hRequest)
{
goto failure;
}
httpHeader = L"Content-type: application/json";
WinHttpAddRequestHeaders(hRequest, httpHeader.c_str(), DWORD(httpHeader.length()), WINHTTP_ADDREQ_FLAG_ADD);

}
const void *ss = (const char *)urlParam.c_str();

}
if (strHttpContent.empty())
{

}
else
