Having Trouble Getting SimpleHTTPRequestHandler to respond to AJAX

Make sure your response has a send_header() with a content type. I have seen AJAX requests get confused without this. You can also try switching your POST to a GET for debugging and make sure the browser can see the content.

Here is a simple HTTP example for returning XML if you point your query or browser to 127.0.0.1/test:

import SimpleHTTPServer, SocketServerimport urlparsePORT = 80class MyHandler(SimpleHTTPServer.SimpleHTTPRequestHandler):   def do_GET(self):       # Parse query data & params to find out what was passed       parsedParams = urlparse.urlparse(self.path)       queryParsed = urlparse.parse_qs(parsedParams.query)       # request is either for a file to be served up or our test       if parsedParams.path == "/test":          self.processMyRequest(queryParsed)       else:          # Default to serve up a local file           SimpleHTTPServer.SimpleHTTPRequestHandler.do_GET(self);   def processMyRequest(self, query):       self.send_response(200)       self.send_header('Content-Type', 'application/xml')       self.end_headers()       self.wfile.write("<?xml version='1.0'?>");       self.wfile.write("<sample>Some XML</sample>");       self.wfile.close();Handler = MyHandlerhttpd = SocketServer.TCPServer(("", PORT), Handler)print "serving at port", PORThttpd.serve_forever()
