Web Server code not working

Jun 8th, 2009
Hi,

I'm trying to build a web server in Python, and here is what I have so far:

Python Syntax (Toggle Plain Text) 
  1. Code:
  2. from http.server import HTTPServer, BaseHTTPRequestHandler
  3.  
  4. class RequestHandler(BaseHTTPRequestHandler):
  5.     def _writeheaders(self):
  6.         self.send_response(200)
  7.         self.send_header('Content-type', 'text/html')
  8.         self.end_headers()
  9.  
  10.     def do_HEAD(self):
  11.         self._writeheaders()
  12.  
  13.     def do_GET(self):
  14.         self._writeheaders()
  15.         self.wfile.write("""<HTML>
  16. <HEAD><TITLE>Sample title</TITLE></HEAD>
  17. <BODY>sample text</BODY>
  18. </HTML>""")
  19.  
  20. serveraddr = ('', 8080)
  21. srvr = HTTPServer(serveraddr, RequestHandler)
  22. srvr.serve_forever()

I do not get any errors, however when it runs the shell opens and nothing happens.
What changes to this code would I do to make it work?

Thanks.

I'm not that familiar with webservers in python but isn't it normal that the server just keeps running in the shell? You should probably use something else to see the servers output? Like a web browser or something?

I put a print statement at the end to make sure that the whole script was executed. It was not.

Did you put a print statement after serve_forever() ? I'm pretty sure that forever indicates a super loop (ie, while True: )

Thanks. Apparently, the code finishes. Whoopse on my part, I usually don't miss those kinds of things.

So, my question is, now what? Once I have my server running, how do I access it and make it secure?

Any help on accessing it and making it more secure would be very helpful.

Thanks.

i think this line
serveraddr = ('', 8080)
binds the server to your localhost at port 8080
so you could try typing localhost:8080 at your webserver
I could fill this thing with great stories and magical experiences.
But i guess i'm just to lazy ...

What about accessing it remotely from a different computer?

Same as above but instead of localhost use the ip address of the computer where the server is running.

Thanks. When I run it and go to it via localhost in my browser (Safari) I get this in the Shell and I get a blank browser page:

  1. localhost - - [11/Jun/2009 16:55:55] "GET / HTTP/1.1" 200 -

Why don't you try sending something simpler... this is an example i found from googling:
python Syntax (Toggle Plain Text) 
  1. class Handler(BaseHTTPRequestHandler):
  2.     def do_GET(self):
  3.         self.send_response(200)
  4.         self.send_header("Content-type", "text/plain")
  5.         self.end_headers()
  6.         self.wfile.write("Hello World!")
