[Zope] Flash XMLRPC clients for Zope ....

[Steve Spicklemire]

Hi Nigel,

	I got so frustrated with Flash Player I just cooked up my own way. 
The version I was using had no way to set content type! I ended up with 
a couple of external methods and a Python Script to use them. There 
is/was also a problem with the Windows version of FlashPlayer. The 
sendAndLoad command is supposed to do a POST, but it sends a "GET" 
command, and then "POST"s anyway. ;-( So I commented out the meth != GET 
below and unconditionally seek/read stdin. I posted a detailed bug 
report to MM, but got no response.

Anyway.. thanks for the update. I wonder if they'll ever get it right?

;-(

External Methods:

rawInput:

def getRawInput(self, REQUEST):

     meth = REQUEST.environ.get('REQUEST_METHOD','GET')

     if 1: # meth != 'GET':
         #
         # Flash has a broken .sendAndLoad() method on Windows.. so we 
need to
         # force a "POST" response rather than handle "GET"
         #

         REQUEST.stdin.seek(0)
         result = REQUEST.stdin.read()
     else:
         result = REQUEST.environ.get('QUERY_STRING','')

     return result


handleXML:

def getRawInput(self, REQUEST):

     meth = REQUEST.environ.get('REQUEST_METHOD','GET')

     if meth != 'GETfoo':
         #
         # Flash has a broken .sendAndLoad() method on Windows.. so we 
need to
         # force a "POST" response rather than handle "GET"
         #

         REQUEST.stdin.seek(0)
         result = REQUEST.stdin.read()
     else:
         result = REQUEST.environ.get('QUERY_STRING','')

     return result


Finally.. here is the PythonScript to use getRawInput and handleXML:

import string

REQUEST=context.REQUEST

rawInput = context.getRawInput(REQUEST)

if len(rawInput):
	try:
		xmlDict = context.handleXML(rawInput)
	except:
		xmlDict = {}
else:
	xmlDict = {}
