CHttpConnection::OpenRequest

[Yves Berquin]

VC++ 5.0

How do I have to send a form to an HTTP server, using a "post" method ?

I tried
CInternetSession * ISp_session;
CHttpFile * HFp_file;
CHttpConnection * HCp_conn;
CStrin S_req;

ISp_session = new CInternetSession;
HCp_conn = ISp_session -> GetHttpConnection ("http://..."); // "action"
in the form
HFp_file = HCp_conn -> OpenRequest (CHttpConnection::HTTP_VERB_POST,
"verb");
S_req = "data=value";
HFp_file -> SendRequest (S_req);

I always get a strange exception, not catched up by CInternetException.
Apparently some argument problem.

Any clue ?

Yves,

>ISp_session = new CInternetSession;
>HCp_conn = ISp_session -> GetHttpConnection ("http://..."); // "action"
in the form

according to docs, GetHttpConnection requires the servername only, not an
URL.

e.g. "myserver" or "10.11.12.13"

>HFp_file = HCp_conn -> OpenRequest (CHttpConnection::HTTP_VERB_POST,
"verb");

instead of "verb" --> here goes the file part, e.g.
"/myweb/scripts/handler.exe" or "myweb/hanlder.asp"

> S_req = "data=value";
> HFp_file -> SendRequest (S_req);

I am not a real expert on this, but there is one clear problem here: you are
trying to send "data=value" as request header, not as data stream (which is
required by POST).

Maybe you should attempt something like

HFp_file->Write("data=value",10);
HFp_file->SendRequest();

Let me admit I have no real experience doing this in C++, but anyway these
remarks should get you going.

Good luck

Hello!
I'm using MFC in VC++ 5.0 to create an application that shall talk to a
web site using SSL.

I have installed the Certificate for SSL on my IIS4.0 server and tried to
view the ASP-pages from my Netscape Navigator/Internet Explorer without
any problem.

When I run my application I get the exception:
"Certification organization invalid" (my translation from swedish)
from the "SendRequest()" function below.

The code works fine if I am not using SSL and remove the flag:
INTERNET_FLAG_SECURE.
Can somebody help me with this? The code follows below.
Regards
Rikard Ambric (amb...@algonet.se)

Code:

DWORD dwAccessType = PRE_CONFIG_INTERNET_ACCESS;

DWORD dwHttpRequestFlags =
INTERNET_FLAG_EXISTING_CONNECT |
INTERNET_FLAG_NO_AUTO_REDIRECT |
INTERNET_FLAG_SECURE;

CHttpConnection* pServer = NULL;
CHttpFile* pFile = NULL;
LPCTSTR pszAppName = _T("appl");
string strURL = "https://www.site.se/appl/page.asp";

CString strServerName;
CString strObject;
INTERNET_PORT nPort;
DWORD dwServiceType;

AfxParseURL(strURL.c_str(), dwServiceType, strServerName, strObject, nPort)
CInternetSession session(pszAppName, 1, dwAccessType);

pServer = session.GetHttpConnection(strServerName, nPort);

pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_GET,
strObject, NULL, 1, NULL, NULL, dwHttpRequestFlags);

pFile->AddRequestHeaders(headers);
pFile->SendRequest();
