我如何将XML格式的数据从flex传递到python

Question

我想将XML格式的数据从flex.python传递给python，我知道如何从flex传递信息，但我的问题是我如何才能在python中获取传递的数据，然后将数据插入mysql.and我也想检索mysql数据到python（cgi），python应该将所有数据转换为xml格式，并将所有数据传递给flex ..谢谢。

See http://www.artima.com/weblogs/viewpost.jsp?thread=208528 for more details, here is a breif overview of what I think you are looking for.

The SimpleXMLRPCServer library allows you to easily create a server. Here's about the simplest server you can create, which provides two services to manipulate strings:

import sys
from random import shuffle
from SimpleXMLRPCServer import SimpleXMLRPCServer

class MyFuncs:
    def reverse(self, str) :
        x = list(str);
        x.reverse();
        return ''.join(x);
    def scramble(self, str):
        x = list(str);
        shuffle(x);
        return ''.join(x);

server = SimpleXMLRPCServer(("localhost", 8000))
server.register_instance(MyFuncs())
server.serve_forever()

Once you make a connection to the server, that server acts like a local object. You call the server's methods just like they're ordinary methods of that object.

This is about as clean an RPC implementation as you can hope for (and other Python RPC libraries exist; for example, CORBA clients). But it's all text based; not very satisfying when trying to create polished applications with nice GUIs. What we'd like is the best of all worlds -- Python (or your favorite language) doing the heavy lifting under the covers, and Flex creating the user experience.

To use the library, download it and unpack it somewhere. The package includes all the source code and the compiled as3-rpclib.swc library -- the .swc extension indicates an archive file, and pieces of this library can be pulled out and incorporated into your final .swf. To include the library in your project, you must tell Flexbuilder (you can get a free trial or just use the free command-line tools, and add on the Apollo portion) where the library is located by going to Project|Properties and selecting "Apollo Build Path," then choosing the "Library path" tab and pressing the "Add SWC..." button. Next, you add the namespace ak33m to your project as seen in the code below, and you're ready to create an XMLRPCObject.

Note: the only reason I used Apollo here was that I was thinking in terms of desktop applications with nice UIs. You can just as easily make it a Flex app.

Here's the entire Apollo application as a single MXML file, which I'll explain in detail:

<?xml version="1.0" encoding="utf-8"?>

            import mx.controls.Alert;

            private function manipulate() : void {
                server.reverse(instring.text).addResponder(new ItemResponder(reverseResult, onFault));
                server.scramble(instring.text).addResponder(new ItemResponder(scrambleResult, onFault));
            }
            private function reverseResult(event : ResultEvent, token : AsyncToken = null) : void {
                reversed.text = event.result.toString();
            }
            private function scrambleResult(event : ResultEvent, token : AsyncToken = null) : void {
                scrambled.text = event.result.toString();
