Accessing Port 80

[catch]

Hello again everyone,

I've just started developing my first PyS60 app. Things have been running good since I have started reading Scheible's book.

Anyway, going to my problem... I have used Scheible's web server code as a first step to a mature server and here it is:

import BaseHTTPServer, SimpleHTTPServer, cgi, traceback, json

class Server(BaseHTTPServer.HTTPServer):
        allow_reuse_address = True

class Handler(SimpleHTTPServer. SimpleHTTPRequestHandler):

    def do_POST(self):
        try:
            size = int(self.headers["Content-length"])
            msg = json.read(self.rfile.read(size))
            reply = process_json(msg)
        except:
            self.send_response(500)
            self.end_headers()
            print "Function process_json failed:"
            traceback.print_exc()
            return

        self.send_response(200)
        self.end_headers()
        self.wfile.write(json.write(reply))

    def do_GET(self):

        if '?' in self.path:
            path, query_str = self.path.split("?", 1)
            query = cgi.parse_qs(query_str)
        else:
            path = self.path
            query = {}

        try:
            mime, reply = process_get(path, query)
        except:
            self.send_response(500)
            self.end_headers()
            print >> self.wfile, "Function process_query failed:\n"
            traceback.print_exc(file=self.wfile)
            return

        self.send_response(200)
        self.send_header("mime-type", mime)
        self.end_headers()
        self.wfile.write(reply)


def process_json(msg):
    return msg

def process_get(path, query):
    return "text/plain", "Echo: path '%s' and query '%s'" %\
               (path, query)

def init_server():
    print "Server starts..."

init_server()
httpd = Server(('', 80), Handler)
httpd.serve_forever()

I ran the code on a local machine and changed the listening port to 80 instead of 9000. I wanted my server to listen and ONLY listen to port 80. However, things didn't work out well. I've got a permission denied on the terminal. Is there a magic to this? With this step, I will be communicating my mobile phone to this server, if this would matter.

Your aid would greatly be appreciated.

Thanks, in advance.

If your 'local machine' runs a Unix-like OS (e.g. Linux, MacOSX), then only the 'root' user may bind a socket to a port number less than 1024.

Also note that the BaseHTTPServer class is not capable of handling multiple requests simultaneously, so you might be better off using apache with mod_python.

@aya42: I have tested it running freely under the root account. It is running very good =)

And, I seem to notice that BaseHTTPServer is limited in listening to the number of requests but this fine for now. However, I'm using and will be sticking with nginx, instead of Apache, as my web server. But your suggestions are most welcome. There's still a big room for improvement for me.

Cheers and Happy Easter!
