send multipart/form-data using httpsendrequest - c++

Question

I'm trying to send multipart/form-data using httpsendrequest in c++ but it doesn't seem to work. I'm using the RFC standard for boundary and this is the code I have. I'm sending simple data, plain but trying to use multipart/form-data so I can understand how boundaries work but it doesn't send. This is the code that I've got so far.
#define _WIN32_WINNT 0x600
#include <stdio.h>
#include <wininet.h>
#define BUFLEN 1024
static LPCTSTR acceptTypes[] = {"*/*", NULL};
static const char *postData = "submit=submit&cool=hawk";
static char headers[] = TEXT("Content-Type: multipart/form-data; boundary=abcde\r\n"
"--abcde\r\n"
"Content-Disposition: form-data; name=\"cool\"\r\n"
"testval\r\n"
"--abcde\r\n");
int main()
{
HINTERNET hSession, hConnect, hFile;
if( ( hSession = InternetOpen(
"myapp",
INTERNET_OPEN_TYPE_PRECONFIG,
NULL,
NULL,
0
) ) == NULL )
{
printf("Couldn't start session. Error %ld\n", GetLastError());
exit(1);
}
printf("Session started\n");
if( ( hConnect = InternetConnect(
hSession,
"localhost",
INTERNET_DEFAULT_HTTP_PORT,
NULL,
NULL,
INTERNET_SERVICE_HTTP,
0,
0
) ) == NULL )
{
printf("Unable to connect to server. Error %ld\n", GetLastError());
exit(1);
}
printf("Connected to server\n");
if( ( hFile = HttpOpenRequest(
hConnect,
"POST",
"/test/index.php",
NULL,
NULL,
acceptTypes,
INTERNET_FLAG_RELOAD,
0
) ) == NULL )
{
printf("Unable to open request. Error %ld\n", GetLastError());
exit(1);
}
printf("Opening request..Opened\n");
unsigned long dataLen = strlen(postData)+1;
bool res = HttpSendRequest(
hFile,
headers,
-1,
(char*)postData,
dataLen
);
if( !res )
{
printf("Unable to send request. Error %ld\n", GetLastError());
exit(1);
}
printf("Request sent\n");
// char *szBuffer = (char*)malloc(sizeof(char)*BUFLEN);
char szBuffer[BUFLEN];
DWORD dwRead = 0;
memset(&szBuffer, '\0', sizeof(szBuffer));
while( InternetReadFile(hFile, szBuffer, sizeof(szBuffer), &dwRead) && dwRead )
{
printf("%s", szBuffer);
}
return 0;
}
