I need a Windows equivalent of this class for a client I'm writing.
class SessionConnection:
# Encapsulate the line-by-line level of a session with a server.
# This class requires Unix services.
param_names = ('host', 'port', 'username', 'password', 'browse')
def __init__(self, file=".intriguer"):
# Initialize a SessionConnection object from user's stored paramters
self.dotfile = os.path.join(os.environ["HOME"], file)
self.host = "snark.thyrsus.com"
self.port = 99999
self.username = "esr@thyrsus.com"
self.password = "fooup"
self.browse = "netscape -remote 'openURL(%s)'"
try:
dfp = open(self.dotfile);
lexer = shlex.shlex(dfp)
while 1:
variable = lexer.get_token()
if not variable:
break
if not variable in Session.param_names:
raise SyntaxError
if lexer.get_token() != '=':
raise SyntaxError
value = lexer.get_token()
if not value:
raise SyntaxError
setattr(self, variable, value);
dfp.close()
except IOError:
pass # if file is absent, fall back to defaults.
self.socket = None
self.sockfp = None
def __repr__(self):
# Dump current session parameters
res = "# intriguer configuration\n"
for p in Session.param_names:
if getattr(self, p):
res = res + "%s=%s\n" % (p, `getattr(self, p)`)
return res
def wrapup(self):
# Update the dotfile to reflect parameter edits
dfp = open(self.dotfile, "w")
dfp.write(`self`);
dfp.close()
# Establish and break server connections
def connect(self):
# Initialize a server connection.
# Not part of the class initialization sequence only because
# we might want to create an instance just to examine or
# edit the parameters.
self.socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self.socket.connect(self.host, self.port)
self.sockfp = self.socket.makefile("r+")
def disconnect(self):
# Terminate a server connection
if self.socket:
self.socket.close()
self.sockfp.close()
# Communication with server
def readline(self):
# Read a raw line from the server
return self.sockfp.readline()
def writeline(self, line):
# Write a raw line to the server
return self.sockfp.write(line + "\n")
# Local service invocations
def browse_url(self, url):
# Point a local browser at a specified URL
os.system(self.browse % url)
The issues here are:
(1) How do I get (at least) line-oriented access to an Internet server
from a Python program running under Windows?
(2) How does one read and write the Windows equivalent of a dotfile?
Must this involve the (shudder) registry?
(3) Is there a reliable way for Python programs under Windows to point a local
browser at a specified URL?
