Carrying an Http Session
Hello,
My friend has a website with registeration system, he asked me to make a java client that asks the same questions and such on site, I was succesful in sending POSTs and reading response, I carried on through the session by resubmitting the HiddenFields, but once I finish the last step the server generates an error, always, maybe I'm not handling cookies very well, please tell me everything I need to supply to carry on a succesful session, also tell me if there's an error in the way I handle cookies:
Note: There's some global variables used in here
public String post(String urlR, String data)
{
String out="";
try{
//sending the first POST request
URL url =new URL(urlR);
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
if(pageCookie != 1)
{
conn.setRequestProperty("Cookie",cookieToBeSent);
conn.connect();
}
else
{
conn.connect();
}
OutputStreamWriter wr =new OutputStreamWriter(conn.getOutputStream());
wr.write(data);
wr.flush();
// Get the response
BufferedReader rd =new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
while ((line = rd.readLine()) !=null)
{
out += line+"\n";
}
wr.close();
rd.close();
cookie ="";
String headerName="";
int cookieCount = 0;
for (int i=1; (headerName = conn.getHeaderFieldKey(i))!=null; i++)
{
if (headerName.equalsIgnoreCase("Set-Cookie"))
{
cookie = conn.getHeaderField(i);
cookieCount++;
StringTokenizer st =new StringTokenizer(cookie,";=");
if(pageCookie == 1 && cookieCount > 1)
{
cookieToBeSent += st.nextToken() +"=";
cookieToBeSent += st.nextToken() +";";
}
}
}
pageCookie++;
}catch (Exception e){}
return out;
}
I've noticed that the server sends cookies just the first time, the other times it just resends the same cookie over and over, so I handeld it that way, but I'm not sure if I'm sending cookies correctly, also the first cookie has a name but no value, and the 2nd cookie has the same name and with value, so I didn't read the 1st one.
