Python + apache Server SETUP

Source: Internet
Author: User

Recently, I used Python + Apache to build a server and found a problem: for the Content-Type of POST request + application/octet-stream, the server always returns the 501 error.

Later, I checked the mod_python/util. py script and found that the configured pythonhandler is mod_python.publisher. For post requests, its content-type has constraints:

109        if req.method != "POST":110            return111 112        try:113            clen = int(req.headers_in["content-length"])114        except (KeyError, ValueError):115            # absent content-length is not acceptable116            raise apache.SERVER_RETURN, apache.HTTP_LENGTH_REQUIRED117 118        if not req.headers_in.has_key("content-type"):119            ctype = "application/x-www-form-urlencoded"120        else:121            ctype = req.headers_in["content-type"]122 123        if ctype.startswith("application/x-www-form-urlencoded"):124            pairs = parse_qsl(, keep_blank_values)125            for pair in pairs:126                # TODO : isn't this a bit heavyweight just for form fields ?127                file = cStringIO.StringIO(pair[1])128                self.list.append(Field(pair[0], file, "text/plain", {}, None, {}))129            return130 131        if not ctype.startswith("multipart/"):132            # we don't understand this content-type133            raise apache.SERVER_RETURN, apache.HTTP_NOT_IMPLEMENTED

Http_not_implemented indicates that the Server Returns Error 501.

It seems that mod_python.publisher cannot be used as pythonhandler!

Therefore, using a Custom Handler as the pythonhandler encountered another problem:

All requests are processed using this handler. As a result, different Python scripts cannot be used to serve different requests.

Think about it and make a roundabout way: use this handler for general control. Each different request dynamically sets its pythonhandler according to the URI.

The index. py script is as follows:

import os;from mod_python import apachedef handler(req):handler = req.uri[1:];if handler[-3:] == ".py" :handler = handler[0:-3];if not handler == "index" :req.add_handler("PythonHandler", handler);return apache.OK;

In this way, with the following configuration file, everything will be OK!

AddDefaultCharset GBKListen 8080<VirtualHost *:8080>#    AddType application/x-http-python .py        DocumentRoot /usr/htdocs    <IfModule alias_module>        Alias /index /usr/htdocs/    </IfModule>        <Directory "/usr/htdocs">        AllowOverride FileInfo        SetHandler mod_python        #PythonHandler mod_python.publisher        PythonHandler index        PythonDebug On        Order allow,deny        Allow from all    </Directory></VirtualHost>

I have mentioned the problem of using the logging module in Apache + python in another blog:
