send data to CGI

[Erik Kjellson]

I want to send data to a CGI script via the method POST.
So I have these lines in the source, but I can't get it work, I think it
must be the casting in the first line.

How can I get rid of the casting?

HttpURLConnection connection = (HttpURLConnection) email.openConnection();
// email is the URL of the CGI script
connection.setRequestMethod("POST");
connection.setDoOutput(true);
PrintStream out = new PrintStream(connection.getOutputStream());
out.println("Name=datorn");
out.close();
} catch(MalformedURLException mue) {
showStatus("Illegal URL: " + mue);
} catch(IOException ioe) {
showStatus("IOException: " + ioe);
} catch(Exception e) {
showStatus("Error: " + e);
}

PS. I've tested URLConnection but it didn't seem to work either DS.

Best regards, Erik

See NetUtil in my utilities package at
http://www.pobox.com/~skeet/java/skeetutil/ for an example of posting in
Java, which you can modify to do what you need to. I've always found
that the order in which you connect etc is quite fragile and badly
documented.

you also need connection.setDoInput(true); and
connection.setAllowUserInteraction(false);

see http://www.bruececkel.com for Bruce's book Thinking in Java, which
explains how to do this in detail.

hi
1-do not use HttpURLConnection in applet because ms explorer bug
2-here is a very good post method :
tf = textfield ta = textarea
public void post1(){
try{
String data="name="+URLEncoder.encode(tf.getText());
URL u=new URL("http://localhost/cgi-bin/prog.cgi");
URLConnection uc=u.openConnection();
uc.setDoInput(true);
uc.setDoOutput(true);
uc.setUseCaches(false);

uc.setRequestProperty("Content-type","application/x-www-form-urlencoded");
uc.setRequestProperty("Content-length",""+data.length());
DataOutputStream dos=new DataOutputStream(uc.getOutputStream());
dos.writeBytes(data);
dos.close();
DataInputStream dis=new DataInputStream(uc.getInputStream());
String line;
while((line=dis.readLine()) != null){
ta.appendText(line);
ta.appendText("\n");
}
dis.close();
}
catch(Exception e){
ta.appendText("post error");
e.printStackTrace();
}
}
