Getting authentication token after a HttpSendRequest
- by Jessica
The following code will log in my application to a server. That server will return an authentication token if the login is successful. I need to use that token to query the server for information.
egressMsg := pchar('email='+LabeledEdit1.text+'&&password='+MaskEdit1.Text+#0);
egressMsg64 := pchar(Encode64(egressMsg));
Reserved := 0;
// open connection
hInternetConn := InternetOpen('MyApp', INTERNET_OPEN_TYPE_PRECONFIG, NIL, NIL, 0);
if hInternetConn = NIL then
begin
ShowMessage('Error opening internet connection');
exit;
end;
// connect
hHttpSession := InternetConnect(hInternetConn, 'myserver.com',
INTERNET_DEFAULT_HTTP_PORT, '', '', INTERNET_SERVICE_HTTP, 0, 0);
if hHttpSession = NIL then
begin
ShowMessage('Error connecting');
exit;
end;
// send request
hHttpRequest := HttpOpenRequest(hHttpSession, 'POST',
'/myapp/login', NIL, NIL, NIL, 0, 0);
if hHttpRequest = NIL then
begin
ShowMessage('Error opening request');
exit;
end;
label2.caption := egressMsg64 + ' '+inttostr(length(egressMsg64));
res := HttpSendRequest(hHttpRequest, Nil,
DWORD(-1), egressMsg64, length(egressMsg64));
if not res then
begin
ShowMessage('Error sending request ' + inttostr(GetLastError));
exit;
end;
BufferSize := Length(infoBuffer);
res := HttpQueryInfo(hHttpRequest, HTTP_QUERY_STATUS_CODE, @infoBuffer, BufferSize, Reserved);
if not res then
begin
ShowMessage('Error querrying request ' + inttostr(GetLastError));
exit;
end;
reply := infoBuffer;
Memo1.Lines.Add(reply);
if reply <> '200' then
begin
//error here
end;
// how to I get the token here!!!!
InternetCloseHandle(hHttpRequest);
InternetCloseHandle(hHttpSession);
InternetCloseHandle(hInternetConn);
How do I get that token? I tried querying the cookie, I tried InternetGetCookie() and a lot more.
Code is appreciated
Thanks

EDIT
I found that if you use InternetReadFile you can get that token. However that token comes out as an array of bytes. It's hard to use it later to send it to the server... anyone knows how to convert an array of bytes to pchar or string?
