Having Trouble Getting SimpleHTTPRequestHandler to respond to AJAX

Question

I recently tried implementing the SimpleHTTPRequestHandler to accept AJAX requests according to this.

Although everything seems to work as far as receiving the request f

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, SocketServer
import urlparse

PORT = 80

class 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("");
       self.wfile.write("Some XML");
       self.wfile.close();

Handler = MyHandler

httpd = SocketServer.TCPServer(("", PORT), Handler)

print "serving at port", PORT
httpd.serve_forever()
