What is server?

Server is a computer which stores data and serving the user request and running forever. We will create a socket and it binds an adress(IP) and Port number.

Implemantation

For creating server we used http.server.HTTPServer as a server and it takes two things server adress(IP,PORT) and handler. When request comes to server internally send request to handler and there are some methods in handler which we overrides for handleing the request.

Server Code:

If we call run() method it creates instance of http.server.HTTPServer by passing server_address and handler_class. Server_address here a list of ip and port. By default IP is localhost and port=80. Here httpd is a server object and after calling httpd.serve_forever() it starting to work and waiting for request.

def run(server_class=HTTPServer, handler_class=ServerHandler, port=80):
    server_address = ('', port)
    httpd = server_class(server_address, handler_class)
    print ('Start working server...')
    try:
        httpd.serve_forever()
    except KeyboardInterrupt:
        httpd.server_close()

ServerHandler

At the time of server creation passes the serverhandler object by creation ServerHandler instanmce. ServerHandler this class we create which is a subclass of http.server.BaseHTTPRequestHandlerand when request comes based on request for handleing we are overwriting the methods of http.server.BaseHTTPRequestHandler.

class ServerHandler(BaseHTTPRequestHandler):
    def _set_headers(self,header='text/html'):
        self.send_response(200)
        self.send_header('Content-type', header)
        self.end_headers()

    def do_GET(self):
        rt = os.path.join(os.path.dirname(os.path.dirname(os.path.abspath(__file__))), 'create-own-server')
        if self.path == '/abc.html' or self.path == '/':
            self.path = '/abc.html'
            filename = rt + self.path
            self._set_headers()
            with open(filename, 'rb') as fh:
                html = fh.read()
                self.wfile.write(html)
        elif self.path.endswith(".jpg"):
            self._set_headers('image/jpg')
            filename = rt + self.path
            with open(filename, 'rb') as fh:
                html = fh.read()
                self.wfile.write(html)
        else:
            self._set_headers()
            self.wfile.write("<!DOCTYPE html><html><body><div><h1>404 NOT FOUND</h1></body></html".encode())

    def do_HEAD(self):
        self._set_headers()
        
    def do_POST(self):
        self._set_headers()
        self.wfile.write("<html><body><h1>POST Section</h1></body></html>")
