parse url form data

[ephemeralz]

i need a function that decodes form data encoded in HTTP GET REQUEST URL:

http://www.myspace.com/formWrite?user=jdoe&name=john+doe

and return a dictionary of key/value pairs representing the
form data. ‘+’ signs in values should be converted to spaces

{'user':'jdoe','name':['john doe']}

below is my attempt:
the problem to the code below is that it's not able to handle mutliple key with same values


import string

print context.standard_html_header(context,context.REQUEST)

firstKeyList=string.split(url,'?')
urlList=firstKeyList[-1]
urlKeyList=string.split(urlList,'&')
urlTuple = ('key',['values'])
urlList = range(len(urlKeyList))

urlTemp=''
urlFinal=''
urlDict= {}

for i in urlList:
urlValueList = string.split(urlKeyList,'=')
for j in range(len(urlValueList)-1):
string.join(string.split(urlValueList[j+1],'+')) + ")"
urlTuple = (urlValueList[j], "['" + string.join(string.split(urlValueList[j+1] + "']",'+')))
string.join(string.split(urlValueList[j+1],'+'))
string.join(string.split(urlValueList[j+1],'+')) + "'),"
urlList = urlTuple

urlList.reverse()
urlDict = dict(urlList)

print urlDict



print context.standard_html_footer(context,context.REQUEST)
return printed

You're reinventing the wheel, use the cgi module:

#!/usr/bin/env python
import cgi

form = cgi.FieldStorage()

urlDict = {}
for key in form.keys():
    urlDict[key] = form.getvalue( key )

print "Content-Type: text/plain\n\n"
print urlDict

http://www.brunson.com/cgi-bin/formWrite.py?one=1&two=1+plus+1&three=1&three=plus&three=2

yields:
{'three': ['1', 'plus', '2'], 'two': '1 plus 1', 'one': '1'}
