Maybe there is some simpliest method but I use something like this:
<code>
// assume I have created socket to required host and port 80
// get output
PrintStream output = new PrintStream(socket.getOutputStream());
// get input
InputStream input = socket.getInputStream();
BufferedReader in = new BufferedReader(new InputStreamReader(input));
// URL
String url = "/path/to/myScript.cgi";
// Host
String host = "my.server.com";
// POST
output.println("POST " + url + " HTTP/1.1");
// Host
output.println("Host: " + host);
// Accept - you can put here any mime type(s) you need
output.println("Accept: text/html");
// Content parameters
// do NOT forget the last "\n"
// it means the end of the request's header!!!
output.println("Content-Encoding: 8859_1\n"
+"Content-Type: application/x-www-form-urlencoded\n"
+"Content-Length: " + data.length() + "\n");
// and now the data
output.println(java.net.URLEncoder.encode("parameter1="+value1)
+"&"+java.net.URLEncoder.encode("parameter2="+value2)
// ... more parameters ...
);
// and now read input (CGI's output)
String line = in.readLine();
while (line!=null)
{
// do something with the line
...
// read next line
line = in.readLine();
}
</code>
I hope it wil help you.
