I want something like BaseHTTPRequestHandler, except that I don't want it to bind to any sockets; I want to handle the raw HTTP data to and from it myself. Is there a good way that I can do this in Python?

To Clarify, I want a class that receives raw TCP data from Python (NOT a socket), processes it and returns TCP data as a resp开发者_运维百科onse (to python again). So this class will handle TCP handshaking, and will have methods that override what I send on HTTP GET and POST, like do_GET and do_POST. So, I want something like the Server infrastructure that already exists, except I want to pass all raw TCP packets in python and not through operating system sockets.

BaseHTTPRequestHandler derives from StreamRequestHandler, which basically reads from file self.rfile and writes to self.wfile, so you can derive a class from BaseHTTPRequestHandler and supply your own rfile and wfile e.g.

import StringIO
from  BaseHTTPServer import BaseHTTPRequestHandler

class MyHandler(BaseHTTPRequestHandler):

    def __init__(self, inText, outFile):
        self.rfile = StringIO.StringIO(inText)
        self.wfile = outFile
        BaseHTTPRequestHandler.__init__(self, "", "", "")

    def setup(self):
        pass

    def handle(self):
        BaseHTTPRequestHandler.handle(self)

    def finish(self):
        BaseHTTPRequestHandler.finish(self)

    def address_string(self):
        return "dummy_server"

    def do_GET(self):
        self.send_response(200)
        self.send_header("Content-type", "text/html")
        self.end_headers()
        self.wfile.write("<html><head><title>WoW</title></head>")
        self.wfile.write("<body><p>This is a Total Wowness</p>")
        self.wfile.write("</body></html>")

outFile = StringIO.StringIO()

handler = MyHandler("GET /wow HTTP/1.1", outFile)
print ''.join(outFile.buflist)

Output:

dummy_server - - [15/Dec/2009 19:22:24] "GET /wow HTTP/1.1" 200 -
HTTP/1.0 200 OK
Server: BaseHTTP/0.3 Python/2.5.1
Date: Tue, 15 Dec 2009 13:52:24 GMT
Content-type: text/html

<html><head><title>WoW</title></head><body><p>This is a Total Wowness</p></body></html>
