Sending Information to a Remote Site
- Just as it is easy to receive data from a server,
it is also easy to send data to a server, or more likely, to a CGI script
on a server.
- In this case, we will use an output and print
stream instead of an input stream as in the following example.
try
{
Socket s = new Socket("www.extropia.com",
80);
OutputStream os = s.getOutputStream());
PrintStream ps = new PrintStream(os);
ps.println("POST /cgi-bin/test.cgi");
ps.println("Content-type: plain/text");
String string = "Hello CGI Script!";
ps.println("Content-length: " +
string.length + "\n");
ps.println(string);
}
catch (IOException e)
{
System.out.println("Error: " + e);
}
- Of course, you could simply use the GET
method by passing the data as URL encoded information by replacing
the first println line above with something more like:
ps.println("GET /cgi-bin/test.cgi?phrase=Hello+CGI+Script");
