submission with POST

[adum]

the puzzles will now accept HTTP POST requests for automated problem submissions. use the same vars as for the GETs. (this first cropped up with Mortal Coil, level 437 -- nasty one.)

The POST-Sbmission seems to be broken. All the Data I submit is ignored. I test it with a test script on my own Server and it received my data, so my program seems to be ok.

How would you do a POST request in java? I'm at level 92 of crossflip, and my code no longer seems to work:

URL u;
u = new URL("http://www.hacker.org/cross/index.php?name=" + $name + "&password=" + $password + "&sol=" + sol);
InputStream is = u.openStream();
BufferedReader in = new BufferedReader(new InputStreamReader(is));

String line;
while ((line = in.readLine()) != null)
{
System.out.println(line);
}
is.close();

that should help

this is the solution posting section of the solver code in Java. it should be easy to adapt this to any game here, just change the url address and the writer.write line with '&' separated key/value pairs like a get line would have. i tried other examples but seems the page here was ignoring me till i added the content-type.

Code: Select all

public boolean solve() throws Exception {
   URL u;
   String path = findSolutionPath();
   System.out.println("solved at (" + startX + ", " + startY
            + ") : " + path);
   String enc="UTF-8";
   u = new URL("http://www.hacker.org:80/coil/index.php");
   URLConnection conn=u.openConnection();
   conn.setDoOutput(true);
   conn.setRequestProperty("Content-Type", 
            "application/x-www-form-urlencoded");        
   OutputStreamWriter writer=new
            OutputStreamWriter(conn.getOutputStream());
   writer.write("name=" + URLEncoder.encode(name, enc) + 
            "&password=" + URLEncoder.encode(pw, enc) + 
            "&path=" + path + "&x=" + startX + "&y=" + startY);
   writer.flush();
   BufferedReader rd = new BufferedReader(new
            InputStreamReader(conn.getInputStream()));
   rd.readLine();
   writer.close();
   rd.close();
   return false;
}
