HttpOpenRequest and HttpSendRequest

[satishsuman]

I am trying to make a HTTP connection with web server and trying to pass
authentication information.

I included INet.h.

My code for http request is..

***************************************************************************************
HINTERNET hSession = ::InternetOpen("SomeName",
PRE_CONFIG_INTERNET_ACCESS,
NULL,
INTERNET_INVALID_PORT_NUMBER,
0) ;

HINTERNET hConnect = ::InternetConnect(hSession,
"http://localhost/login",
INTERNET_DEFAULT_HTTP_PORT,
user_id,
password,
INTERNET_SERVICE_HTTP,
0,
0) ;

SetLastError(0);
HINTERNET hHttpFile = ::HttpOpenRequest(hConnect,
"POST",
"",
HTTP_VERSION,
NULL,
0,
INTERNET_FLAG_DONT_CACHE,
0);

if(hHttpFile)
{
DWORD dwErr = GetLastError();
char message[1000];
sprintf(message, "Ya! Success! - Error = %u", dwErr);
MessageBox(NULL, message, "HttpOpenRequest", MB_OK);
}
else
{
DWORD dwErr = GetLastError();
char message[1000];
sprintf(message, "No! Failure! - Error = %u", dwErr);
MessageBox(NULL, message, "HttpOpenRequest", MB_OK);
}

INTERNET_BUFFERS inBuf;
inBuf.dwStructSize = sizeof(INTERNET_BUFFERS);
inBuf.Next = NULL;
inBuf.lpcszHeader = NULL;
inBuf.dwHeadersLength = 0;
inBuf.dwHeadersTotal = 0;

char postData[1000];
sprintf(postData, "user_id=%s&password=%s", user_id, password);
inBuf.lpvBuffer = postData;
inBuf.dwBufferLength = strlen(postData);
inBuf.dwBufferTotal = strlen(postData);

inBuf.dwOffsetLow = 0;
inBuf.dwOffsetHigh = 0;

INTERNET_BUFFERS outBuf;
outBuf.dwStructSize = sizeof(INTERNET_BUFFERS);
outBuf.Next = NULL;
outBuf.lpcszHeader = NULL;
outBuf.dwHeadersLength = 0;
outBuf.dwHeadersTotal = 0;
outBuf.lpvBuffer = new char[1000];
outBuf.dwBufferLength = 1000;
outBuf.dwBufferTotal = 1000;
outBuf.dwOffsetLow = 0;
outBuf.dwOffsetHigh = 0;

SetLastError(0);

BOOL bSendRequest = ::HttpSendRequestEx(hHttpFile, &inBuf, &outBuf,
HSR_SYNC, NULL);

if(bSendRequest)
{
DWORD dwErr = GetLastError();
char message[1000];
sprintf(message, "Ya! Success! - Error = %u", dwErr);
MessageBox(NULL, message, "HttpSendRequest", MB_OK);
}
else
{
DWORD dwErr = GetLastError();
char message[1000];
sprintf(message, "No! Failure! - Error = %u", dwErr);
MessageBox(NULL, message, "HttpSendRequest", MB_OK);
}

*****************************************************************************************************************
HttpOpenRequest works an return message is Ya! Success! Error = 122
HttpSendRequestEx goes in else and gives message No! Failure! Error = 87.

What is wrong with my code?

First, you have to understand, that if the function returns TRUE, there is
no need to look at error code - it does not have meaning.

> HttpSendRequestEx goes in else and gives message No! Failure! Error = 87.

I bet you got errors just because LPINTERNET_BUFFERS lpBuffersOut for
HttpSendRequestEx is reserved, and should be NULL. Also, you do not pass
correct url into InternetConnect. It should be withOUT http://.

I will attach a complete working source code in next message. You will be
able to download the source code if you use Outlook Express.

Probably you're accessing the newsgroup from google.com. I suggest you to
use Outlook Express (OE) and configure it to use msnews.microsoft.com NG
server. Then, find newsgroup microsoft.public.inetsdk.programming.wininet.
You will be able to access attachments only from OE.

I'm very interested in seeing your code. I opened this thread in OE, but
apparently
the thread has been archived. When I opened your response, there was not an
attachment available. Any chance you would repost, including the attachment?

Much appreciated,

reply here within 24 hours.
