question about python
I was working through a tutorial about how to write a server using
python (the url is bellow). I am sure that the server is working to
some degree because when the server is running localhost:8080 just
keeps trying to load until it times out. I would like to know how to
send information through the server to my browser?
I was working through this tutorial:
http://python.about.com/od/networkingwithpython/ss/PythonWebServer.htm
and my final code is like this:
import socket
host = ''
port = 8080
c = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
c.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
c.bind((host, port))
c.listen(1)
while 1:
csock, caddr = c.accept()
cfile = csock.makefile('rw', 0)
line = cfile.readline().strip()
cfile.write('HTTP/1.0 200 OK\n\n')
cfile.write('Welcome %s!' %
(str(caddr)))
cfile.write('Follow the link...')
cfile.write('All the server needs to do is ')
cfile.write('to deliver the text to the socket. ')
cfile.write('It delivers the HTML code for a link, ')
cfile.write('and the web browser converts it. ')
cfile.write(' http://python.about.com/
index.html">Click me! ')
cfile.write('The wording of your request was: "%s"' %(line))
cfile.write('')
cfile.close()
csock.close()

Re: question about python
@ Carl: Yes, I think your right now that I look at it (or at least all
except for the last two lines need to be indented). I'm still not sure
how to send the stuff to the web browser though. Thanks for pointing
it out!
@ Diez: I'll start googling those right away.

When you had suggested that I indent the lines at first I did all of them, but when I did that there must have been an nonindented line before the last two lines which I had indented, so ending the 'while 1:'. Because of that, that code just flat out didn't work so I assumed that they must be not be indented which is why it hasn't been working all along. Thanks for your help! I don't think I would have every figured it out if you last post hadn't gotten me to thinking about little tweeks like that. -- http://mail.python.org/mailman/listinfo/python-list
