I've noticed there's a problem with Rebol's standard decode-cgi function.
Here's the source:
>> source decode-cgi
decode-cgi: func [
{Converts CGI argument string to a list of words and value strings.}
args [any-string!] "Starts at first argument word"
/local list equate value name val
][
plus-to-space: func [arg /local seek chr] [
if any [none? arg empty? arg] [return ""]
seek: arg
while [seek: find seek #"+"] [
change seek #" "
seek: next seek
]
head arg
]
list: make block! 8
equate: [copy name to "=" "=" (append list to-set-word name) value]
value: ["&" (append list copy "") | [copy val to "&" "&" | copy val to
end]
(append list either none? val [copy ""] [form dehex plus-to-space
val])]
parse/all args [some equate | none]
list
]
Note that 'plus-to-space is created inside 'decode-cgi each time it's used.
It can also be easily replaced with 'replace/all. Also, CRLF aren't
converted to Rebol's newline. This replacement function should fix these
problems:
Decode-CGI: function [
{Converts CGI argument string to a block of set-words and value
strings.}
Args [any-string!] "Starts at first argument word."
] [
Block Name Value
] [
Block: make block! 10
parse/all Args [
any [
copy Name to #"=" skip (
append Block to-set-word Name
)
[
#"&" (
append Block copy ""
)
| [copy Value to "&" "&" | copy Value to end] (
append Block either none? Value [
copy ""
] [
replace/all dehex replace/all Value #"+" #" " CRLF
newline
]
)
]
]
end
]
Block
]
I've sent it in to feedback.
